Description
RELATED APPLICATIONS
[0001] This application is a division of U.S. patent application
Ser. No. 12/391,044, filed Feb. 23, 2009, which is a continuation
of U.S. patent application Ser. No. 09/441,892, filed Nov. 17,
1999. These applications are incorporated herein by reference.
BACKGROUND ART
[0002] Sparked by the concept of an information superhighway, a
revolution will take place in the distribution of books. Not since
the introduction of Gutenberg's movable typeset printing has the
world stood on the brink of such a revolution in the distribution
of text material. The definition of the word "boor will change
drastically in the near future. Due to reasons such as security,
convenience, cost, and other technical problems, book and magazine
publishers are currently only able to distribute their products in
paper form. This invention solves the problems encountered by
publishers.
Technical Field And Brief Summary Of Invention
[0003] The electronic book selection and delivery system is a new
way to distribute books to bookstores, public libraries, schools
and consumers. The technological breakthroughs of this invention
provide a secure electronic system for both delivering selected
books and receiving payments. The system has an unusual combination
of features that provides the consumer with a daily use household
appliance that has a high tech aura while being very practical,
portable, and easy to use.
[0004] An advantage of the system is that it eliminates the
distribution of any physical object such as a paper book or
computer memory device from any book or text distribution system.
The purchase of a book becomes a PAY-PER-READ.TM. event avoiding
the overhead, "middle-men," printing costs, and time delay
associated with the current book distribution system. Published
material and text such as the President's speech, a new law, a
court decision on abortion, or O. J. Simpson's testimony can be
made immediately available to the consumer at a nominal fee.
Alternatively, books may be made available free to the end use
consumer, subsidized by advertisers who sponsor books or embed
advertising within the books.
[0005] The system is a novel combination of new technology
involving the television, cable, telephone, and computer
industries. It utilities high bandwidth data transmissions, strong
security measures, sophisticated digital switching, high resolution
visual displays, novel controls, and user friendly interface
software.
[0006] The primary components of the text delivery system are the
subsystem for preparing the text for delivery and the subsystem for
receiving and selecting text that was delivered. An embodiment of
the system includes additional components and optional features
that enhance the system. The system may be configured for use by
bookstores, public libraries, schools and consumers. in one
embodiment, the system for consumer use is made up of four
subsystems, namely: (1) an operations center, (2) a distribution
system, (3) a home subsystem including reception, selection,
viewing, transacting and transmission capabilities, and (4) a
billing and collection system. Alternative configurations of the
system are defined to allow for a variety of traditional and
non-traditional delivery methods.
[0007] The operations center performs several primary functions:
manipulating text data (including receiving, formatting and storing
of text data), security encoding of text, cataloging of books,
providing a messaging center capability, and performing uplink
functions. In one embodiment, the system delivers the text from the
operations center to consumer homes by inserting text data within
analog video signals. The insertion of text is generally performed
with an encoder at an uplink site that is within or near the
operations center. The system can use several lines of the Vertical
Blanking Interval (VBI), all the lines of the analog video signal,
a digital video signal or unused portions of bandwidth to transmit
text data. Using the VBI delivery method, the top ten or twenty
book titles may be transmitted with video during normal programming
utilizing existing cable or broadcast transmission capability
without disruption to the subscriber's video reception. Using the
entire video signal, thousands of books may be transmitted within
just one hour of air time. Nearly any analog or digital video or
data distribution system may be used to deliver the text data. The
text data may also be transmitted over other low and high speed
signal paths including a telephone network (e.g., a public switched
telephone network) having a high speed connection such as a digital
subscriber line (DSL) connection and the Internet, for example.
[0008] The home subsystem performs at least four functions:
connecting to the distribution system, selecting text, storing
text, and transacting through a communicating mechanism. The
components of the home subsystem may be configured in a variety of
hardware configurations. Each function may be performed by a
separate component, the components may be integrated, or the
capability of existing cable set top converter boxes, computers,
and televisions may be utilized. A connector, library unit and
viewer unit may be used. In one embodiment, the connector portion
of the home subsystem receives an analog video signal and strips or
extracts the text from the video. The home library stores the text
signal, provides a user friendly software interface to the system
and processes the transactions at the consumer home. The viewer
provides a screen for viewing text or menus and novel user friendly
controls. Alternative embodiments are presented that support
delivery of text using a variety of communication mechanisms.
[0009] The viewing device may be a portable book shaped viewer
which stores one or more books for viewing and provides a screen
for interacting with the home library unit. A high resolution LCD
display is used to both read the books and to interact with the
home library software. In one embodiment, an optional phone
connector or return-path cable connection initiates the telephone
calls and, with the aid of the library, transmits the necessary
data to complete the ordering and billing portion of the consumer
transaction. Alternative embodiments are presented that support
ordering and billing using a variety of communication mechanisms.
The user friendly controls include a bookmark, current book and
page turn button. The billing and collection system performs
transaction management, authorizations, collections and publisher
payments automatically. A system similar to the system for consumer
use may be used in bookstores, schools and public libraries.
[0010] The system also provides for various electronic commerce
features. The viewer displays identification of products or
services and permits the user obtain information concerning them or
execute purchase requests for them. The system may display related
products or services to the user and also target advertising to the
particular user. For certain products, the user may obtain a sample
of it. For digital products, the user has the option to download
the product directly into the viewer or library.

DETAILED DESCRIPTION OF INVENTION
[0065] FIG. 1a shows an electronic book distribution system 100
that may be used for distributing an electronic book. A content
provider 110 may publish hard copy versions of books or other
printed media including newspapers, Magazines, and product
catalogs, for example. The content provider 110 may convert printed
materials to an electronic format and provide the electronic
formatted materials to a distribution point, or center 120, over
uplink path 115. The uplink path 115 may be a wired or a wireless
path. The uplink path 115 may be a telecommunications network, for
example. The uplink path 115 may be a satellite relay path or a
wireless telephone path. The uplink path 115 may involve providing
electronic books to the distribution center on a fixed media, such
as a CD-ROM, for example.
[0066] In FIG. 1a, the content provider 110 and the distribution
center 120 are shown as separate components of the electronic book
distribution system 100. However, the content provider 110 and the
distribution center 120 may be co-located.
[0067] The distribution center 120 may convert printed matter into
an electronic format. Alternately, the distribution center 120 may
receive electronic files from an outside source, such as the
content provider 110. The distribution center 120 may process and
store electronic books.
[0068] The distribution center 120 distributes electronic books.
The distribution may be, for example, over distribution path 125,
distribution network 130, and distribution path 135 to an
electronic book subsystem or terminal 140, which may include an
electronic book viewer (not shown). The terminal may also be a
television, a set top terminal, a personal computer, or similar
device. An apparatus and method for distributing electronic books
is disclosed in greater detail later. The distribution network 130
may be an electronic book store, an Internet web site, a wired or
wireless telecommunications network, an intranet, a radio program
delivery system, a television program delivery system, including
cable television, satellite television broadcast, and over-the-air
broadcast, for example. The electronic book distribution network
130 could include direct delivery through a mail delivery system of
electronic books on a fixed media, such as a CD-ROM, for
example.
[0069] FIG. 1b shows components of an electronic book distribution
system 170 using a television program delivery system to distribute
electronic books.
[0070] In the embodiment shown in FIG. 1b, the components of the
electronic book selection and delivery system 170 are an encoder
174, a video distribution system 178, a connector 182, and a text
selector 186. The encoder 174 places textual data on a video signal
to four a composite video signal. Although the composite signal may
contain only textual data, it usually carries both video and
textual data. A variety of equipment and methods may be used to
encode text data onto a video signal. The video distribution system
178 distributes the composite video signal from the single point of
the encoder 174 to multiple locations, which have connectors 182.
The connector 182 receives the digital or analog video signal from
the video distribution system 178 and separates, strips or extracts
the text data from the composite video signal. If necessary, the
extracted text data is converted into a digital bit stream. The
text selector 186 works in connection the connector 182 to select
text.
[0071] Using the connector 182 and text selector 186 combination,
various methods of selecting and retrieving desired text from a
composite or video signal are possible. Text may be preselected,
selected as received or selected after being received and stored.
One method is for the connector 182 to strip or extract all the
text from the video signal and have the text selector 186 screen
all the text as received from the connector 182. The text selector
186 only stores text in long term or permanent memory if the text
passes a screening process described below.
[0072] FIG. 2 shows another embodiment of an electronic book
selection and delivery system 200. The delivery system 200
includes: an operations center 250 including an uplink site 254, a
video distribution system 208, an electronic book device, or home
system 258 including a video connector 212, a library 262, a viewer
266, and a phone connector 270, telephone system 274, an Internet
web site 279 and a billing and collection system 278. Also as shown
in FIG. 2, the home system 258 may include connections to a
television 259 and a personal computer 261 may be used to display
menu screens, electronic books, electronic files, or any other
information associated with the electronic book delivery system
200. In addition, the television 259 and the personal computer 261
may provide control functions that replicate and supplement those
of the viewer 266.
[0073] The operations center 250 receives textual material from
outside sources 282 such as publishers, newspapers, and on-line
services. Alternately, the outside sources may maintain electronic
books at the Internet web site 279. The outside sources 282 may
convert textual and graphical material to digital format, or may
contract with another vendor to provide this service. The
operations center 250 may receive the textual and graphical
material in various digital formats and may convert the textual
material to a standard compressed format for storage. In so doing,
the operations center 250 may create a pool of textual material
that is available to be delivered to the home system 258. The
textual material may be grouped by books or titles for easy
access.
[0074] As used herein, "book" means textual or graphical
information such as contained in any novels, encyclopedias,
articles, magazines, newspapers, catalogues, periodicals, or
manuals. The term "title" may represent the actual title assigned
by an author to a book, or any other designation indicating a
particular group, portion, or category of textual information. The
title may refer to a series of related textual information, a
grouping of textual information, or a portion of textual data. For
example, "Latest Harlequin Romance", "Four Child Reading Books
(Ages 10-12)," "Encyclopedia BRITANNICA.TM.," "President's Speech,"
"Instruction Manual," "Schedule of 4th of July Events," "Pet
Handbooks," "Roe v. Wade," and "The Joy of Cooking," are suitable
titles. Also, the title may be a graphical symbol or icon. Thus, a
picture of a wrench may be a title for a repair book, a picture of
a computer a title for a computer book, a graphical symbol of a
telephone a title for a telephone book, a drawing of a dagger a
title for a mystery book, a picture of a bat and ball a title for a
sports book, and a picture of tickertape a title for a business
book.
[0075] The operations center 250 includes the uplink site 254 for
placing the text onto a telecommunications signal and sending the
telecommunications signal into a distribution system. The uplink
site 254 would generally include an encoder 204 (not shown in FIG.
2) to encode the text onto the telecommunications signal.
[0076] Many analog and digital video distribution systems may be
used with the electronic book delivery system 200, such as cable
television distribution systems, broadcast television distribution
systems, video distributed over telephone systems, direct satellite
broadcast distribution systems, and other wire and wireless video
distribution systems. Nearly any distribution system which can
deliver a telecommunications signal, including a video signal, will
work with the electronic book delivery system 200. It is also
possible to distribute the electronic book without using a
telecommunications signal as described in the embodiments presented
in Section VII below.
[0077] The home system 258 performs five functions: (1) connecting
with a video distribution system; (2) selecting data; (3) storing
data; (4) displaying data; and (5) handling transactions. An
important optional function of the home system 258 is communicating
using, in one embodiment, a telephone communication system 274. The
home system 258 may be made up of four parts: a video connector 212
or similar type of connector for connecting with the distribution
system 208, a library 262 for storing and processing, a viewer 266
for viewing menus and text and a telephone connector 270 for
connecting with a telephone communications system 274. Additional
embodiments are presented in Section VII that address alternative
communication mechanisms.
[0078] The billing and collection system 278 may be co-located with
the operations center 250 or located remote from the operations
center 250. The billing and collection system 278 may be in
communication with the home system 258 using telephone-type
communication systems (for example 274). Any of a number of
communication systems as presented in Section VII, such as a
cellular system or the Internet, will operate with the billing and
collection system 278. The billing and collection system 278
records the electronic books or portions of text that are selected
or ordered by the subscriber. The collection system will charge a
subscriber's credit account or bill the subscriber. In addition,
the billing and collection system 278 may monitor that amount due
to publishers or other outside sources 282 who have provided
textual data or other services such as air time to enable the text
delivery system 200 to operate.
[0079] Also shown in FIG. 2 is an intranet 279'. The intranet 279'
may be used as a part of a private distribution network for
distributing and circulating electronic books. For example, a
university library may use the intranet 279' to circulate
electronic books to university students and professors.
[0080] FIG. 3 is an expanded overview of a delivery plan 301 for
the electronic book delivery system 200. It is a comprehensive
delivery plan 301 to support various types of users and various
billing systems. FIG. 3 shows that publishers 282 may provide text
transfer 302 to the operations center 250' and receive payments 306
from the billing and collection system 278'. A separate channel
uplink site 254' is shown in this configuration receiving data 310
from the operations center 250'. The operations center 250' has
three separate sections (318, 322, 326) one for text receiving,
formatting and re-entry 318, a second for security encoding 322 and
a third section for catalog and messaging center functions 326.
[0081] The collection and billing system 278' shown has two
sections (330, 334) one for transaction management, authorizations
and publisher payments 330, and the other for customer service 334.
The customer service section 334 provides for data entry and access
to customer account information. Transaction accounting information
338 is supplied to credit card companies 342 by the transaction
management section 330 of the billing and collection system 278'.
The credit card companies 342 provide billing 346 to customers
either electronically or by mail.
[0082] Methods for communicating between the subscriber base 348
and the billing and collection system 278' include: by telephone
switching 350 alone, cellular switching 354 and telephone switching
350 combined, and by use of the cable system 358 and the telephone
switching 350. The system shown supports both one-way 362 and
two-way cable communication 366 with subscribers. Additional
communication methods are presented in Section VII. Public
libraries and schools 370 as well as bookstores 374 may use the
delivery system 301.
[0083] Public libraries and schools 370 could have a modified
system to allow the viewer to be checked-out or borrowed while
bookstores 374 would rent or sell the viewer and sell electronic
book data. The bookstores 374 as well as the public libraries and
schools 370 may be serviced by cable 378. Optional direct broadcast
systems (DBS) 382 can also be used with the system 200 as detailed
in Section VII.
[0084] I. The Operations Center
[0085] FIG. 4 is a schematic of the operations center 250, which
includes the uplink 254. The operations center 250 may gather text
or books by receiving, formatting, storing, and encoding. A data
stream 302 containing text may be received at the operations center
250 by a data receiver 402. The data receiver 402 is under the
control of a processor 404. After reception, the data stream is
formatted using digital logic for formatting 406 which is also
under the control of the processor 404. If any additional text is
generated at the operations center 250 locally for insertion into
the distributed signal, the text generation is handled through text
generator hardware 410, which may include a data receiver and a
keyboard (not shown). Following processing by the text generator
410, the additional text can be added to the text received by the
combining hardware 414 that includes digital logic circuitry (not
shown).
[0086] The processing at the operations center 250 is controlled by
a processor 404, which uses an instruction memory 416. The
processor 404 and instruction memory 416 may be supplied by a
personal computer or mini-computer, for example. To perform the
catalog and messaging functions, the operations center 250 uses a
catalog and message memory 420 and the text generator 410 if
necessary.
[0087] The data stream of text, catalog and messages may be encoded
by security module encoding 424 prior to being sent to the uplink
module 254. Various encoding techniques may be used by the security
encoding module 424 such as the commercial derivative of NSA's
encryption algorithm (Data Encryption System (DES)) and General
Instrument's DigiCipher II. Following encoding, the encoded text
may be stored in text memory 428 prior to being sent to the uplink
254. A first-in-first-out text memory arrangement may be used under
the control of the processor 404. Various types of memory may be
used for the text memory 428 including RAM. The operations center
250 may use file server technology for the text memory 428 to
catalog and spool books for transmission as is described below. The
operations center 250 may also store the electronic book as
compressed data files.
[0088] In an embodiment, to transmit textual data, the distribution
system 208 (see FIG. 2) may use high bandwidth transmission
techniques such as those defined by the North American Broadcast
Teletext Standard (NABTS) and the World System Teletext (WST)
standard. Using the WST format (where each line of the Vertical
Blanking Interval contains 266 data bits), a four hundred page
book, for example, may be transmitted during regular television
programming using four lines of the Vertical Blanking Interval at a
rate of approximately one book every 1.6 minutes (63,840 bits per
second). Alternatively, books may be transmitted over a dedicated
channel, which interrupts programming so that 246 lines of video
can be used to transmit approximately 2,250 books every hour (3.9
Mbits per second). A teletext type format is the simplest but
possibly the slowest text format to use with the electronic book
delivery system 200. In either event, an encoder 204 may be used at
an uplink site 254 to insert textual data into the analog video
signal. In many other respects, the delivery of the textual
information may be completed using an existing cable television
plant and equipment. Alternative transmit formats and delivery
systems are presented in Section VII.
[0089] FIG. 5a is a flowchart of steps involved in processing text
from the publisher or provider 282 that may occur at the operations
center 250. As shown in block 500, the publisher 282 processes data
files of text for books, compresses, encrypts and sends the data
files to the operations center 250 or uplink 254. Text files for
books may be sent one book at a time. As shown in block 504, the
uplink 254 or operations center 250 receives and processes the data
stream from the publisher 282. Generally, part of this processing
includes encryption and error correction. Text files may be
delivered for receipt by multiple home subsystems simultaneously,
or to a specific individual home subsystem.
[0090] In FIG. 5a, the electronic books are distributed to
consumers using a video distribution system such as a cable
television system. However, the electronic books may also be
packaged as data packets and distributed over other
telecommunications networks such as a digital wireless telephone
network, for example.
[0091] In one embodiment, as shown in block 508, files are broken
into smaller packets of information. Header information is added to
the packets. The bit stream is converted from a serial digital bit
stream to an analog bit stream that is compatible with an NTSC
video signal. Block 512 shows the switching of analog data into the
video lines of a video signal. The analog data may be placed either
in the VBI or the active video lines. In some instances, unused
portions of bandwidth (such as 5-40 MHZ, 70-75 MHZ, 100-109 MHZ or
other guard bands) may be used instead of the video lines.
Alternate transmission methods are presented in Section VII.
[0092] FIG. 5b is an example of a hardware configuration to perform
some of the functions for blocks 508 and 512. A video feed 516 is
received and processed through a sync stripper 520. The stripped
sync signal 532 is used by the digital logic control 524. The
digital logic control 524 receives the sync signal 532 and a serial
digital bit stream 528 for processing. The digital logic control
524 passes the serial digital bit stream to the Digital to Analog
converter 536 and outputs a control signal 540 for the video switch
544. The video switch 544 integrates the video feed 516 and analog
data stream 548 into a video feed with analog data signal inserted
552.
[0093] As an alternative to cable, broadcast or other television
delivery methods, the public telephone system may be used to
transmit books to the subscribers. An average book would take about
7 minutes to transmit over the public telephone system. Using the
telephone system, it is not necessary to combine video and text
into a composite signal. In most other respects, the operations
center would remain similar whether text delivery was by telephone
or cable. File server technology (such as that described in U.S.
Pat. No. 5,262,875, entitled AUDIO/VIDEO FILE SERVER INCLUDING
DECOMPRESSION/ PLAYBACK MEANS, issued to Mincer, et al., and, U.S.
Pat. No. 5,218,695, entitled FILE SERVER SYSTEM HAVING HIGH-SPEED
WRITE EXECUTION, issued to Noveck, et al., incorporated herein by
reference) may be used at the operation center with a telephone
system text delivery method.
[0094] As another alternative to cable, television, and telephone
system delivery, the public telephone system may be used to provide
access to the Internet, where the Internet web site 279 may be
accessed. Electronic books may be ordered, paid for, and delivered
directly from the Internet web site 279 over the telephone
system.
[0095] When a wireless telephone network is used to distribute
electronic books, or otherwise communicate with the home system
258, the home system may receive data using any one or more
standard protocols including time division multiple access (TDMA),
code division multiple access (CDMA), Global Systems for Mobile
Communications (GSM) and Advanced Mobile Telephone System (AMPS)
protocols.
[0096] In any delivery system using the telephone system,
individual subscribers may increase the electronic book deliver
rate by incorporating high speed modems or other communications
devices such as an Integrated Services Digital Network (ISDN)
connector, or by use of a Digital Subscriber Line (DSL). These
alternative delivery methods are presented in Section VII.
[0097] II. The Home Subsystem
[0098] The hardware configuration for a four component home system
258 is shown in FIG. 6a. FIG. 6b shows a hardware configuration for
a two component home subsystem. The home system 258 performs
several functions, such as receiving data and video transmissions,
stripping (or extracting) the data from the video signal, screening
and storing the data, providing user friendly interface controls
and software, displaying menus and text, processing transactions,
initiating telephone calls and transmitting billing data. Various
hardware configurations may be utilized to achieve the desired
functions of the home system 258. For example, as shown in FIG. 6b,
the home system 258 can be configured to utilize the reception and
channel tuning capability of the current installed subscriber base
of cable converter boxes and televisions 601 and networked
computers. The home system 258 can also be designed as an advanced
set top terminal converter box with menu generation capability,
electronic memory and a telephone modem as described in section V
below. Alternatively, the home system 258 can be configured to
support alternate delivery and ordering methods as described in
Section VII.
[0099] The electronic components, which make up the home system 258
can be arranged in a variety of ways. In the four unit subsystem of
FIG. 6a the viewer 266 and library 262 are wired together while the
remaining components communicate through RF transceivers 604. In a
simple version of the home system 258 there are only two units, a
library 262 and a viewer 266. FIG. 6b shows a two unit home system
258 with certain optional features.
[0100] The viewer 266 is generally equipped with a high resolution
viewing area 602, digital logic (including a key 605, security 606,
and a microprocessor 621), video graphics control and memory 607,
power supply circuitry 602 (not shown), an optional battery 603 and
an optional RF transceiver 604. In a two unit arrangement, the
library 262 contains the connector function to the electronic book
distribution system 208, connector function to a public telephone
communications system, and memory 600 (which may be removable and
portable 600'). More specifically, the library 262 would include
data stripping functions 617, digital logic 609, memory storage
600, power circuitry 610, optional connections 611 (including
cellular or PCN 611'), optional battery (not shown), optional tuner
module 613 and an optional RF transceiver 604. The connector 212
and the public telephone system connection 270, as well as the
removable portable memory unit 600 of the library 262 may be broken
out into separate components. (FIG. 6b shows a removable portable
hard disk memory 600' with removable cartridges 614.) Finally, the
home system 258 may include an attached keyboard 267 or a wireless
keyboard 268. Both the attached keyboard 267 and the wireless
keyboard 268 may be used to communicate with the viewer 266 (not
shown) or the library unit 262. The wireless keyboard 268 may
communicate using radio frequency (RF) signaling, for example.
[0101] In an alternate arrangement, all functions of the home
system 258 may be incorporated into a single unit. The functions of
the library 262, for example, may be carried out by a card or
chipset in the viewer 266. All the communications devices needed to
couple the home system 258 to various telecommunications networks
may also be incorporated into the viewer. All interfaces between
the home system 258 and the subscriber may be included with the
viewer 266. In this embodiment, the viewer 266 may include a
communication device for receiving inputs from a separate keyboard.
The viewer 266 may also include a built-in video camera 608'' that
may be used to transmit images of the subscriber. Using the
transceiver 608, the camera 608'' and the speaker/microphone 608',
the subscriber may use the viewer 266 for video conferencing, for
example.
[0102] Therefore, the home system 258 may have as many as five
separate components, which communicate with each other. The two,
three, four or five separate components which make up the home
subsystem can communicate with each other in a variety of ways,
including hardwired connection 615, RF transceiver 604 and other
wireless methods.
[0103] RF communications may be used in the home, allowing separate
components to be located throughout the home without restriction.
The data communicated between the units may be secure data. In
addition, the library 262 may provide power to the viewer 266
through the hard wire communication link 615.
[0104] To receive and strip data from a video signal at the
consumer's home, a device such as a cable interface device or cable
connector 212 is used. The cable connector device includes a tuner
613, while the cable interface device makes use of existing tuning
equipment in the home. In either configuration, data is stripped
from the video signal and stored at the subscribers location in the
library 262. The phone connector 270, optional connector 611, and
modular connector 701 initiate communications and transmit ordering
and billing information to the operations center 250 or billing and
collection system 278. A digital connector 619 is provided to
communicate digital information with the set top 601. The library
262 is the intelligent component of the home subsystem,
incorporating the hardware and software necessary to store the text
data, generate menus and effect the purchase transactions. In
addition to an RF transceiver 604, the home library 262 also
includes the necessary jacks and connections to allow the system to
be connected to the viewer 266. As shown in FIG. 6b, the library
262 communicates the text data to the viewer 266 in a secure
format, which requires a key 605 for decryption. The text may be
decrypted page by page just before viewing.
[0105] a. The Video Connector
[0106] FIG. 7 shows the flow of the processes performed by the
video connector 212. The video connector 212 receives the video
signal 608, tunes to the channel containing the text data 612,
strips the text data from the video signal 616, and communicates
the text data stream to logic components in the library 620.
[0107] The connection to the video distribution system may be a
cable connector to a cable television delivery system, as shown in
FIG. 6b. The cable connector includes a data stripper circuit 617,
which accepts video input from either a set top converter, TV or
VCR 601, or an optional tuner block 613 that receives the CATV
signal through the cable connector 212'. The data stripper circuit
617 strips data out of the video, and outputs a digital bit stream
to the digital logic portion 609 of the library unit 262. The data
is embedded in the video signal either in the vertical blanking
interval or the active video portion in an encrypted and compressed
format. The data stripper circuit 617 can be placed inside the set
top converter box 601, TV, or in the library unit. The data
stripper circuit 617 outputs the digital bit stream to be used by
the library digital logic 609.
[0108] The video connector 212 may also contain a channel tuner
module 613 that can tune to the video channel and provide access to
the video that contains the data to be stripped. Using the optional
tuner module 613, a set top converter, VCR, or TV tuner is not
needed in the home subsystem. The optional tuner module 613 would
instead receive the CATV signal directly through the cable
connector 212. Additional connector options. which allow for the
receipt of text files using alternative delivery methods, are
presented in Section VII. This ubiquitous access is provided using
the modular connector 700 as depicted in FIG. 6b.
[0109] b. Library
[0110] An embodiment of the library 262 for a two unit home
subsystem is shown in both FIG. 6b and FIG. 8. The embodiment shown
includes the following optional parts: the video connector 212,
phone connector 270, RF transceiver 604, and battery pack 624 in
addition to a removal portable memory 600', microprocessor 628,
instruction memory unit 632, digital logic 636, and power unit
640.
[0111] The library 262 contains a digital logic section 609 (not
shown in FIG. 8) which includes the microprocessor 628, the digital
logic 636 and the instruction memory unit 632. The microprocessor
628 may be a secure microprocessor such as the Mot SC21 device sold
by Motorola. The digital logic section 609 will receive the serial
digital bit stream from the data stripper circuit 617 and process
the data. Error correction will also be performed by the digital
logic section 609 and the data will be checked for proper address.
If the address of the data is correct and the library 262 is
authorized to receive the data, the data will be transferred to the
memory storage unit 600, 600'. Authorization to receive the data is
provided by the cable headend or another distribution point. An
authorization code may be sent in the serial digital bit stream.
The digital logic section 609 will send appropriate text and
graphical data to the memory storage unit 600, 600'. It transfers
this data in a compressed and encrypted format and the data remains
stored in a compressed and encrypted format.
[0112] i. Memory Storage Unit
[0113] The memory storage unit of the library may be a removable
portable memory unit 600' (as shown in FIGS. 6a, 6b and 8). A
variety of options are available for memory storage: a hard disk
drive, such as an 80 megabyte, a 200 megabyte, a hard disk with
removable platters, and CD ROM. Referring to FIG. 6b, a hard disk
drive unit 600', which contains removable platters, may also be
used. This would provide virtually unlimited library storage
capacity. Data will be stored in the memory storage unit in a
compressed and encrypted format. As is also shown in FIG. 6b, the
data may also contain a key or unique ID number that matches the ID
or key of the viewer 266. This matching of a unique key or ID
number prevents unauthorized transfer of text data from the memory
storage unit to an unauthorized viewer. Small memory devices such
as smart cards, electronic memory cards or PCM CIA cards (personal
computer memory card industry association) may also be used to
store the data.
[0114] ii. Power Circuitry
[0115] As shown in FIGS. 6b and 8, the library 262 will accept
power from AC wall power 610, DC power 640, or optional battery
power 624. The power circuitry 610, 640 may provide all the voltage
necessary from either the battery 624 or AC unit for the various
circuitry in the library. The power circuitry 610, 640 may also
provide power to the viewer through a single data cable when
connected to the viewer. The power circuitry 610, 640 will recharge
the battery using AC power when in operation. With the optional
battery unit 624 installed, the library 262 becomes a portable unit
and can still provide power to the viewer 266. In order to extend
battery life, power conservation measures may be utilized, such as
shutting down the memory system when not in use. When the viewer
unit 266 is being utilized and the library circuitry is not being
utilized, virtually all power may be shut down to the library
262.
[0116] iii. Connection to the Public Telephone System
[0117] In an embodiment, the connection to the telephone system may
be provided by a connector device 611, which consists of a modem.
Various available modems may be used to perform this function. As
shown in FIG. 6b, cellular phone or PCN phone connections 611' may
also be provided. When the home system 258 is first initialized,
the modem may be used to transfer the name and credit card
information of the consumer to the billing and collection system
278. The telephone connection 270 may be utilized each time an
electronic book is purchased by a consumer to complete and record
the transaction. The telephone connection 270 may also be used to
receive the text data from the operations center 250, by-passing
the video distribution system 208. The phone connection 270 may be
a separate unit as shown in FIG. 6b. However, alternate means exist
to connect the home system 258 to the billing and collection system
278 or the operation center 250. The modular connector 701 (shown
in FIGS. 6b and 8) provides access to each communication network to
provide a path from the home system 258 to the billing and
collection system 278 or the operations center 250. These
alternatives are presented in detail in Section VII.
[0118] iv. Library Processing
[0119] FIG. 9 shows for one embodiment, an example of processing
performed by the digital logic section 609 of the library 262 on
the data stream 651 received from the video connector 212 or
stripper circuit 617. In step S650, digital logic section 609
checks the data stream 651 for error correction. If an error is
detected, in step S654 digital logic section 609 de-interleaves the
data and in step S658 runs a FEC (Forward Error Correcting)
algorithm. In steps S650, S654 and 5658, the digital logic section
609 performs the error correction needed on the data stream. If no
error correction is necessary the digital logic section 609
proceeds to step 5662 and checks data packets individually for
packet address.
[0120] If the address is a unique address, the process moves to
step S666 and the digital logic section 609 checks whether the
address of the packet matches the library box ID number. The
library box ID number is a unique number associated with the
library 262. The library box ID is used to ensure security of the
data. The process then moves to step S670 and the digital logic
section 609 determines whether an electronic file has already been
opened into which the data packet can be saved. If no data file has
been opened; the digital logic section 609 opens a new data file
for that packet. If an electronic file has been opened, the process
moves to step 5678 and the digital logic section 609 saves the
packet in the electronic file on disk. The process moves to step
682 and the digital logic section 609 checks to see if this is the
last packet for a particular book for a particular textual data
block being received. If it is the last packet of information, the
process moves to step 686 and the digital logic section 609 closes
the electronic file and updates the directory of available
electronic files. Following either step 5682 or S686, the process
returns to receive another data packet from the data stream
received from the data stripper block.
[0121] If the packet address is checked and the address is
determined to be a broadcast address, the process moves to step
S690 and the digital logic section 609 determines the type of
message that is being sent. The message may be an index of book
titles, menu (and menu graphics) information, announcements,
special offerings, discounts, promotions, and previews, for
example. The process then moves to step S694 and the digital logic
section 609 stores the message in an appropriate electronic Message
file. The process then returns to step S650 to receive another data
packet and perform another error check.
[0122] Using the process of FIG. 9, the library 262 is able to
receive, store and update directories related to the textual data
and graphical data (that can be used to depict pictures in a given
book or to generate menus). Variations of the processes are
possible depending on the format of the data and operating system
of the library 262.
[0123] FIG. 10 shows an example of the processing of information
requests from the viewer 266 at the library 262. Information
requests from the viewer 266 are received either through the cable
connecting the viewer 266 to the library 262 or through wireless
transmissions such as RF. It is possible in some embodiments for
subscribers' requests to come from a set top converter box 602 (see
Section V).
[0124] Information requests received from the viewer 266 generally
fall into three categories: (1) directory data of books stored in
the library 262, (2) index of all available books on the system,
and (3) requests for a specific book (step S700). In step S704, the
digital logic section 609 answers a request from the viewer 266 for
a directory of data showing the books stored at the viewer 266. The
directory of data is sent to the viewer 266 so that it may be
displayed to the subscriber. In step 5708, the digital logic
section 609 handles requests from the viewer 266 for an index of
all available books on the system. The library 262 will obtain an
index of all the available books on the system and transmit that
index, in step 5712, with menu information to the viewer 266. In
step 5716, the digital logic section 609 replies to a request from
the viewer 266 for a specific book. In step S720, the digital logic
section 609 opens an electronic file for the specific book
requested by the viewer 266 and transmits the record or transmits
the information on a packet-by-packet basis to the viewer 266. This
process of transmitting the specific book, record, or packets to
the viewer 266 continues until the last record or packet has been
sent in step S724.
[0125] In addition to the processes shown on FIG. 10 in handling a
request for a specific book, the library 262 also orders and
receives specific books from the operations center 250 using the
process as described in step 5716. Following a request for a
specific book which is not stored at the library 262, the library
262 will proceed to determine the next available time the book will
be on the video distribution system 208 or an alternative delivery
system and ensure reception and storage of that book (process not
shown). In performing this process the library 262 will transmit to
the viewer information on when it will obtain the text data for the
book so that the subscriber may view the book. In addition to
timing information, price and other ordering information may also
he passed by the library 262 to the subscriber.
[0126] c. The Viewer
[0127] FIG. 11 is a block diagram of a viewer 266 showing its
internal components. The viewer 266 of FIG. 11 is similar to the
viewer 266 depicted in FIG. 6b. The viewer 266 is designed to
physically resemble a bound book. The viewer 266 is made up of five
primary components and seven optional components: (1) LCD display
602, (2) digital circuitry (not shown), (3) video graphics
controller 607', (4) controls 740, (5) book memory 728, (6)
optional power supply circuitry 736, (7) optional battery 603', (8)
optional RF transceiver 604, and (9) optional cellular or mobile
connector (such as 611') (10) optional keyboards 267 and 268, and
(11) an optional speaker/microphone 608', (12) optional alternative
communication interface devices.
[0128] (1) A high resolution LCD screen 602, of VGA quality, may be
used by the viewer 266 to display text and graphic images. The
screen may be the size of one page of an electronic book. A two
page screen or two screens may also be used with the viewer
266.
[0129] (2) Digital circuitry that includes a secure microprocessor
621, instruction memory 732, and digital logic. Data is transferred
to the viewer 266 in compressed and encrypted format. The secure
microprocessor 621 compares the ID number of the viewer 266 with
the incoming data stream and only stores the text data if the ID
number of the viewer 266 matches that within the incoming data
stream. The viewer 266 may be configured to not output text data or
other data and that the data is decompressed and decrypted only at
the moment of viewing and only for the current page being viewed.
These measures provide additional security against unauthorized
access to data.
[0130] (3) A video graphics controller 607' that is capable of
assisting and displaying VGA quality text and graphic images is
included in the viewer 266. The graphics controller 607' is
controlled by the digital circuitry described above. Text may be
displayed in multiple font sizes.
[0131] (4) The viewer 266 of FIG. 11 has touch panel controls 740.
These unique and novel controls 740 allow the consumer to select
stored electronic books and electronic books from catalogues, move
a cursor, and turn pages in an electronic book. Typically, the
controls 740 include forward and reverse page buttons 742, 741, a
ball 743 for cursor movement, one or more selection buttons 745, a
current book button 747 and a bookmark button 749 (see FIG.
14a).
[0132] The controls 740 should be easy to use and conveniently
located. Referring to FIG. 14a, the controls for the viewer 266 may
be located below the screen 602 at the bottom portion of the viewer
266. The next page turn button 742 is the most used button 740 and
is located towards the right edge of the page. The subscriber is
likely to use right hand thumb movements to work the controls
particularly the page turn buttons 741, 742. Therefore, the buttons
may be arranged in such a manner that the buttons are easily
controlled by a subscriber's right thumb. Generally, this can be
accommodated either on the lower portion of the viewer 266 (as
shown) or along the right hand margin of the viewer 266 (not
shown). The current book button 747 and bookmark button 749 are
usually the least used of the controls 740. Therefore, in the
example shown, those buttons 747, 749 are located on the inside
portion towards the binder of the viewer 266.
[0133] Locating the ball 743 or other cursor movement device (such
as four pointer arrows not shown) in the bottom center of the
viewer 266 is both easier for the subscriber to use and easier in
manufacturing the viewer 266. The selection buttons for the cursor
745 may be located below the middle diameter of the cursor ball 743
on the right and left sides of the ball as shown. If pointer arrows
are used for cursor movement, a selection button 745 may be located
in the center of the four arrow buttons (not shown). Again, the
most used controls 740 should be located where a subscriber's right
hand thumb would normally rest.
[0134] (5) Book memory 728 for at least one electronic book or more
of text is included in the viewer 266. The memory 728 stores text
and any graphics, which represent pictures in a book. The memory
728 can also store menu graphics data. Two different memory 728
devices may be used in the viewer 266, one for the instructions for
the microprocessor 621 in the digital circuitry and a second type
of memory may be used for the book memory 728 (and graphics).
Various memory devices available on the market may be used such as,
ROM, RAM or a small hard disk. Since an electronic book requires
approximately 0.6 megabytes of storage, a small hard disk providing
approximately 60 MBytes of storage provides memory to store
approximately 100 electronic books.
[0135] Text for electronic books may be displayed in various font
sizes. To accommodate various fonts for display, a variety of fonts
are stored in instruction 732 or book memory 728. Thus larger or
smaller fonts may be recalled from memory 621, 728 to create
displays desired by the subscriber.
[0136] (6) Power supply circuitry 736 in the viewer 266 will accept
power from either an AC power source or from an optional battery
603', or the library 262. The power supply circuitry 736 provides
the necessary voltages to accommodate the various systems within
the viewer 266.
[0137] (7) An optional battery 603' is provided in one embodiment.
The battery 603' is automatically recharged when AC power is
available.
[0138] (8) An optional RF transceiver 604 which provided two-way
data link between the viewer 266 and other components of the home
subsystem can also be included in the viewer 266.
[0139] (9) Also, the viewer 266 may include a cellular transceiver
(not shown) for mobile communications.
[0140] (10) The optional wired (attached) keyboard 267 and wireless
(e.g., RF) keyboard 268 (see FIG. 6a) may be used with the viewer
266 to provide communications between the subscriber and the viewer
266.
[0141] (11) The optional speaker and microphone 608' allow the
viewer 266 to provide audio signals to the subscriber, and allow
the subscriber to provide an audio input. The speaker and
microphone 608' may be used in conjunction with the cellular
transceiver 608 or other telecommunications equipment to provide
for reception and transmission of telephony and data.
[0142] (12) The optional alternative communication interface
devices allow the viewer 266 to make use of a variety of
communication paths.
[0143] The viewer 266 of FIG. 11 has parts available for providing
connections to: a library 744, electronic card memory 748, CD ROM
units 752, and a portable memory unit 756 (such as that shown in
FIG. 6b as 600'). Various electronic memory cards such as PCMCIA
can be used with the viewer 266 to supply and store electronic
books.
[0144] Security, low power consumption and excellent display
technology are desired features of the viewer 266 design. The
viewer 266 should be lightweight and portable. The viewer 266
contains a software operating system that allows electronic books
to be stored, read and erased and includes the capability to order
electronic books and retain them in memory 728 for a predefined
period of time determined by the system operator. The software can
be configured to allow the electronic book to be read during a
period of time (i.e., two weeks) and then automatically erased,
read once and erased, or held in memory permanently. Each viewer
266 may have a unique key 605. All of the data storage may be
encrypted with the key 605 for an individual viewer 266 to prevent
more than one viewer 266 accessing the text file or electronic book
file.
[0145] FIG. 12 is a flow diagram of some of the processes executed
by the microprocessor 621 in the viewer 266. The viewer 266 may
receive inputs from the subscriber through touch panel controls
740. In step S800, the subscriber's information requests are then
processed by the microprocessor 621.
[0146] In step 5804, if the subscriber requests a menu of available
electronic books, the microprocessor 621 will select an electronic
book menu. In step 5808, the microprocessor 621 will open the
electronic files that list the electronic books which are available
(related to the category of topic of the menu) and display the menu
with the names of the available electronic books.
[0147] If the subscriber selects a particular book to read, then in
step S812, the microprocessor 621 will process the selection and
determine the electronic file that contains the specific electronic
book. In step S816, the microprocessor 621 will open the file for
that specific electronic book and normally access the first page.
(If a pointer has already been set in that books electronic file,
the process may default to that page.) In step S820, the
microprocessor 621 will then determine which page needs to be
displayed. That is, the microprocessor 621 will determine whether a
next page, previous page or a bookmarked page needs to be
displayed. If the pointer for the electronic file is not in the
correct location then in step S828, the microprocessor 621 will
move the pointer and obtain the previous page of data from the
stored file. Otherwise, in step S824, the microprocessor 621 will
normally obtain the next page of text from the stored electronic
file. In step 5832, the microprocessor 621 will decrypt and
decompress the text data and send the data to the video display.
The video display will generally have a video display memory
associated with it. In step 5832, the microprocessor 621 will send
the data directly to that video display memory. The circuitry for
the display then completes the process of displaying the page of
text.
[0148] If the subscriber, through the controls 740, requests (from
step S800) that the power be turned off, then in step S836, the
microprocessor 621 initiates power off. In step S840, the
microprocessor 621 saves the pointer in memory to the page number
in the book that the viewer 266 is currently reading. In step S844,
the microprocessor 621 closes all the electronic files and signals
the power circuitry to shut down the power to the various circuits
in the viewer 266. With these examples of basic processes the
viewer 266 is able to display book selections and display text from
those electronic books.
[0149] d. Menu System
[0150] Referring generally to FIG. 13, the electronic book system
200 may have a menu system 851 for selecting features and books
from the electronic book system 200. The operating software and
memory required for the menu system 851 may be located at the
viewer 266 (e.g., the instruction memory 732 and/or book memory
728). However, it can also be located at the library 262 (e.g., the
instruction memory 632) or the library 262 and the viewer 266 can
share the software and memory needed to operate the menu system
851. Since the menus are usually displayed on the viewer, and since
the viewer 266 may be capable of operating in the absence of the
library 262, the basic software and memory to create the menus is
more conveniently located at the viewer 266.
[0151] The menu system 851 allows sequencing between menus and
provides menu graphics for graphical displays such as on the LCD
display 602 of the viewer 266. In an electronic book system that
uses a set top converter these menus may also be displayed on a
television screen. In an electronic book system that uses a
computer, these menus may also be displayed on the computer
monitor. In an embodiment, the menus provide just basic text
information from which the subscriber makes choices. In other
embodiments, the menus provide visual displays with graphics and
icons to assist the subscriber and allow for subscriber interaction
and real-time ordering of electronic books or other content
available to the subscriber.
[0152] FIG. 13 depicts the menu system 851 with sequencing. The
primary menus in the menu system 851 are an introductory menu 850,
a main menu 854 and various submenus 858. In the embodiment shown,
there are three levels of submenus 858. In certain instances one or
two submenus 858 is sufficient to easily direct the subscriber to
the selection or information requested. However, there are features
in which three or more submenus 858 make the user interface more
friendly for the subscriber. Each level of submenus 858 may consist
of multiple possible menus for display. The particular menu
displayed depends on the selection by the subscriber on the
previous shown menu. An example of this tree sequence of one to
many menus are the help submenus 887, 888. Depending upon the
specific help requested, a different level two help menu is
displayed to the subscriber.
[0153] An example of an introductory menu 850 is shown on FIG. 14a.
Generally the introductory menu 850 introduces the viewer 266 to
the system and provides initial guidance, announcements and
instruction. The introductory menu 850 is followed by a main menu
854, an example of which is shown in FIG. 14b. The main menu
provides the viewer 266 with the basic selection or features
available in the system. FIG. 14b is an example of a main menu 854
offering many additional features and submenus 858 to the
subscriber. For example, FIG. 14b shows that the viewer 266 is able
to choose by a point and click method, many options including.: (1)
free previews, (2) books you can order, (3) books in your library,
(4) your current book, (5) help, (6) on-line services and (6) other
system features. Following a selection on the main menu 854, a
corresponding submenu 858 is shown.
[0154] FIG. 13 shows fourteen available primary or first level
submenus. They are (1) account set up 862, (2) free previews 866,
(3) book suggestion entries 855, (4) books in your library 872, (5)
books you can order 878, (6) your current book 884, (7) help 887,
(8) available features 890, (9) messages 893, (10) account
information 896, (11) outgoing message submenu 898, (12) show links
submenu 970, (13) create links submenu 980, and (14) show
interactive files submenu 990. FIG. 14c is an example of a first
level submenu for books in your library 872. This "Book In Your
Library" example submenu 872 shows six available books by title and
author and provides the subscriber with the ability to check a
different shelf of books 874 or return to the main menu 854. FIGS.
14d and 14e show example submenus 858 for books that may be ordered
using the "Books You Can Order" submenu 878.
[0155] FIG. 14f is an example of a confirmation menu which confirms
a subscribers order. In this particular example, the subscriber is
required to enter a PIN number to complete the subscriber's order.
Any alpha-numeric or similar password may be used to ensure the
subscriber is an authorized subscriber. In one embodiment, the
subscriber confirms an order with a PIN or password and then
receives a final confirmation screen. The final confirmation screen
is primarily text and may state: [0156] Your book order is now
being processed using CABLE. [0157] Your book will be delivered
overnight and your VISA account will be charged $2.95. [0158] Your
book will be available for reading at 6:00 AM EST tomorrow. Make
sure that: [0159] 1. your Library Unit and Cable Connection Unit
are plugged in with aerials up tonight; and [0160] 2. you tune your
cable converter to THE BOOK Channel. The TV set does not have to
remain on. or similar language.
[0161] Examples of the "Account Set Up Menu" 862 and further
submenus 858 related to account set up (which provide instructions
and account input 864) are shown in FIGS. 14g and FIG. 14h. These
submenus 858 allow initialization of an account at the operations
center 250 and orders to be charged to credit cards. The submenus
858 include the ability to enter data related to your desired PIN
number or password, credit cards, phone numbers, etc. In one
embodiment, the account set up be performed using the telephone
system. A confirmation menu verifies that the account has been
properly set up with the desired PIN or password and credit card.
However, additional set-up methods are presented in Section
VII.
[0162] Free previews for books 866 are also provided by submenus
(868, 870). Examples of the free preview menus are shown in FIG.
14i and FIG. 14j. FIG. 14i shows a menu depicting various books for
which previews are available for viewing. Following a book
selection, a screen submenu showing an excerpt of the selected book
cover's description is provided along with an excerpt from a
critic's review of the selected book. In one embodiment, this
preview screen for a particular book also allows the subscriber to
select a submenu which provides information about the author. The
book preview submenu may also include a still video picture or
graphics portraying a book cover or a scene from the book. An
example of such a still video picture or graphics is shown in FIG.
14j which depicts a preview screen 870 about the author. The
author's preview screen 870 shows a picture of the author, provides
a short biography, and may allow the subscriber to order the
author's books. The price for ordering the authors various books
may also be shown on the menu.
[0163] In addition to free previews, in other embodiments, the
electronic book system 200 provides the subscriber with a book
suggestion feature (see 855). This is accomplished using the menu
system 851 and the processor with associated memory located at the
viewer 266, library 262 or at the distribution point (1020 or 250).
When necessary, information for the book suggestion feature is sent
in the text data of the signal to the home system 258. With this
feature, books or authors are suggested to a subscriber based upon
historical data of the subscriber's previous orders, demographics
or mood of the subscriber, other indicators, and/or by text word
searches.
[0164] In one book suggestion embodiment, text word searches of
preview information (such as book cover descriptions, critics
reviews and biographies about the author) and/or text of books or
other titles are performed by the library 262 using databases
stored in the library memory 600. Personalized book or author
suggestions are made to the subscriber by obtaining information
from the subscriber indicative of general subscriber interests.
Subscriber entries may be solicited from the subscriber using the
book suggestion entry submenu 855. The system uses these subscriber
entries either directly or indirectly to search for books or
authors to suggest to the subscriber.
[0165] Generally, the electronic book suggestion methods may be
categorized into two categories, either responsive methods (which
respond to a series of subscriber menu entries), or intelligent
methods (which analyze data to suggest a book). Using a responsive
or intelligent method, the system 200 determines a list of
suggested titles or authors and creates a second or third level
submenu 856, 857 to suggest the titles for subscriber
selection.
[0166] Responsive methods of suggesting titles include, for
example, the use of mood questions, searching for authors, and
keyword searching. Using the instruction memory 732 and menu
generation hardware (e.g., 607) of the viewer 266, a series of mood
questions can be presented on menus to determine a subscribers
interest at a particular time. For this methodology, the operations
center's 250 processor 404 and instruction memory 416 assign each
title mood indicators (and sub-indicators) from a group such as
light, serious, violent, short, long, dull, exciting, complex,
easy-read, young theme, old theme, adventure, romance, drama,
fiction, science-fiction, etc. These indicators are sent to the
home system 258 with the text data and are stored in library memory
600. Based upon the subscriber entries, the processor associates a
set of indicators with the subscriber's request and a set of books
with matching indicators are located for suggesting to the
subscriber.
[0167] Responsive searches for authors or keywords (a search word
provided by the subscriber) are generally performed by the library
processor 628 and instruction memory 632 on data stored in the
library memory 600. For example, a keyword given by the subscriber
may be searched for a match in library memory 600 storing the book
reviews, critics and previews databases. Thus, if a subscriber
provided an entry of the word "submarine" on an appropriate
submenu, the title "Hunt For Red October" may be located by the
microprocessor 628 using instruction from a routine in instruction
memory 632.
[0168] Intelligent methods of suggesting programs include analyzing
personal profile data on the subscriber and/or historical data
about the subscriber such as past books ordered by the subscriber
(or buy data). This method may be performed at the distribution
point or operations center 250 by the on-site processor 404 using
subscriber databases stored in memory 428. The home system 258
receives the text data including program suggestion information
from the distribution point or operations center 250 and generates
the program suggestion submenus 855, 856, 857 using the same text
data receiving 212 and viewer menu generation hardware (e.g., 607,
621) described above. Software routines and algorithms stored in
instruction memories (e.g. 632, 732) are used to analyze historical
data and book ordered data to determine a line of books to suggest
to the subscriber.
[0169] The algorithms for this powerful feature of suggesting books
or authors to subscribers is disclosed in great detail in U.S. Pat.
No. 5,798,785, entitled TERMINAL FOR SUGGESTING PROGRAMS OFFERED ON
A TELEVISION PROGRAM DELIVERY SYSTEM, filed Dec. 2, 1993, which is
incorporated, herein by reference.
[0170] Referring to FIG. 13, submenus 858 are shown on the "Books
In Your Library" submenu 872 and may be broken into shelf numbers
with submenus for each shelf 874, 876. The submenus 858 for the
"Books You Can Order" submenu 878 is similarly broken out into
submenus by shelves 880, 882. These shelves may each be a category
or genre of books. Books may be grouped into categories such as
best sellers, novels, fiction, romance, etc. See FIG. 14d.
[0171] Referring to FIG. 13, the submenu 858 for "Your Current
Book" 884 allows a subscriber to select a current book 884 and then
determine what page to view. This selection is confirmed with a
level two submenu 885. The help submenu 887 provides the subscriber
with additional help screens 888. The submenus 858 for available
features 890 may be broken out into a sequence of separate submenus
for each feature 891, 892.
[0172] Referring to FIG. 13, messages can also be sent with the
electronic book selection and delivery system 200. A level one
message screen provides the subscriber with the ability to select
from various messages the subscriber has pending 893. Each message
is then shown on a separate submenu screen 894, 895. The message
may contain text and graphics.
[0173] Referring to FIG. 13, account information is shown on a
level one submenu 896 and then follow-on submenus 858 show the
recent orders and your account balance 897. There is also a level
one submenu for outgoing messages 898 which has a follow-on submenu
used as an input screen 899.
[0174] In addition to the specific features and submenus described
in FIG. 13 and FIG. 14a through FIG. 14j, many other variations and
features are possible. When a book is finally selected for viewing
the title page 886 will appear on the screen followed by a page of
text.
[0175] III. The Billing And Collection System
[0176] In one embodiment, the billing and collection system 278
(shown in FIGS. 2 and 3) utilizes the latest technology in
electronic transaction and telephone switching to track orders,
authorize deliveries, bill consumers, and credit publishers
automatically.
[0177] The telephone calls initiated by the phone connector 270 are
received by the billing and collection system 278 which responds
immediately without human intervention by placing the order and
charging the consumers credit card account. Data is compiled
periodically and publishers 282 are credited for sales of their
books or other text. The billing and collection system 278 may also
connect with subscribers through two-way cable connections,
cellular, or other communication means. These additional methods
are detailed in Section VII.
[0178] The billing and collection system 278 communicates with the
operations center to track changes in available books and to
provide statistical data to the operations center 250.
[0179] IV. Public Library, School, and Bookstore System
[0180] The electronic book system can be modified to be used at
public libraries, schools, bookstores, newsstands, or stand-alone
kiosks. FIG. 15 shows one possible arrangement of components for
the distribution location. The main unit is the file server 900.
The file server 900 is a large electronic memory unit that can
store thousands of books, newspapers, or periodicals. Various
electronic storage means may be used in the file servers, such as
hard disks, read-write CD ROMs and read-only CD ROMs.
[0181] The system comprises five components; the file server 900, a
converter or video connector 904 or connector capable of
interfacing to one of the alternative delivery systems presented in
Section VII, a controller 908, a viewer 912, and a catalog printer
916. The software for controlling the system is primarily located
in the controller 908. The converter or video connector 904 is
similar to those described above. In this configuration the
controller unit 908 monitors the data being transferred to the file
server 900 by the converter 904. The controller 908 may be provided
with a viewing screen and several control buttons. When it is
necessary to have a larger screen to perform more sophisticated
controlling of the system a viewer 266 may be connected to the
controller 908 and the viewer screen and controls 740 may be
used.
[0182] For security reasons, the controller 908 is only able to
download books to public viewers 912 which are authorized to
receive books from the particular file server 900. Also for
security reasons it is not desirable that the public viewer 912
have access to more than one file server 900. In this way, security
can be maintained over the text data for books. The public viewer
912 may be limited to receiving one or two books at a time from the
controller 908. When the user of the public viewer 912 needs a new
or additional book, the user returns the viewer 912 to the school
or public library where the user receives a new book from the
controller 908.
[0183] In order to track the books that are available on the file
server 900, the titles of the available books may be printed on a
catalog printer 916. The catalog printer 916 is connected to the
library controller 908 and the titles of the books are downloaded
to the catalog printer 916. For security reasons, the coded text
for any of the electronic books may not be authorized for printing
using the controller 908 and catalog printer 916. In order to
maintain security over the data, none of the electronic book data
may be allowed to be downloaded to the printer 916. Once a complete
printout of available book titles, magazines, or other textual
material is complete, a hard copy of the catalog 920 can be
maintained at the file server 900.
[0184] The system shown may also be used at bookstores. The
bookstores can rent the public viewer 912 to customers with the
text for one or two books loaded onto the public viewer 912. The
public viewer 912 may be provided with an automatic timeout
sequence. The timeout sequence would erase the textual data for the
books after a certain period of time, for example, two weeks. It is
expected that after a period of time (perhaps within two weeks) the
renter would return the public viewer 912 to the bookstore and
receive additional books for viewing. Using this arrangement, it is
also possible for the bookstore to (permanently) sell a viewer 912
to a regular customer. The customer then returns to the bookstore
from time to time to receive textual data for a book which the
customer can then store permanently on the customer's own viewer
912. Various other configurations are possible for bookstores,
schools and public libraries using the file server 900 and public
viewer 912 described.
[0185] V. Use Of A Set Top Converter
[0186] Existing set top converter boxes such as those made by
Scientific Atlanta or General Instruments are presently unequipped
to handle the book selection system of the present invention.
Although set top converters may be built which include the library
functions, hardware modifications are necessary in order to use the
book selection system with existing set top converter
technology.
[0187] FIGS. 16a and 16b are examples of hardware modifications or
upgrades. A port is used to attach hardware upgrades described
below to a set top terminal. Two upgrades are possible to set top
converters 601 to assist in receiving and selecting electronic
books, a menu generation card upgrade (FIG. 16a) and an information
download unit (FIG. 16b). Each of these upgrades may be connected
to the set top terminal unit through an upgrade port. A four wire
cable, ribbon cable, FireWire (WEE 1394B) interface connector, USB
connector, or the like may be used to connect the upgrade to the
set top converter 601.
[0188] A card addition 950, to a set top converter 601 is depicted
in FIG. 16a. The card 950 shown provides the additional
functionality needed to utilize the book selection system with
existing set top converter 601 technology. The card 950 may be
configured to slip inside the frame of a set top terminal and
become part of the set top terminal, an advanced set top terminal.
The primary functions the card 950 adds to the set top converter
601 are the interpreting of data signals, generating of menus,
sequencing of menus, and, ultimately, the ability of the subscriber
to select a book using either the television or a viewer 266. The
card 950 also provides a method for a remote location, such as the
cable headend, to receive information on books ordered. The books
ordered information and control commands may be passed from the
cable headend to the card 950 using telephone lines or alternative
ordering methods as presented in Section VII.
[0189] The primary components of the card 950 are a PC chip CPU
952, a VGA graphic controller 954, a video combiner 956, logic
circuitry 958, NTSC encoder 960, a receiver 962, demodulator (not
shown), and a connector 611', which consists of a dialer. The card
950 operates by receiving the data text signal from the cable
headend through the coaxial cable. The logic circuitry 958 of the
card 950 receives data 964, infrared commands 966, and
synchronization signals (not shown) from the set top converter 601.
Menu selections made by the viewer 266 on the remote control are
received by the set top converter's 601 IR equipment and passed
through to the card 950. The card 950 interprets the IR signal and
determines the book (or menu) the subscriber has selected. The card
950 modifies the IR command to send the information to the set top
converter 601. The modified IR command contains the channel
information needed by the set top converter 601. Using the phone
line 968 and dialer 611', the card 950 is able to transmit
electronic books ordered information to the cable headend. It is
also possible to receive the electronic books over the telephone
lines and other telecommunications networks, including wireless
networks, and by-pass the video distribution system.
[0190] These commands are passed through the interface linking the
set top terminal's microprocessor with the microprocessor of the
hardware upgrades. In this way, subscriber inputs, entered through
the set top terminal keypad or remote control, can be transferred
to any of the hardware upgrades for processing and responses
generated therein can then be sent back to the set top terminal for
display. In one embodiment the IR commands 966 are transferred from
set top terminal 601 to hardware upgrade.
[0191] Hardware upgrades may include a microprocessor, interactive
software, processing circuitry, bubble memory, and a long-term
memory device. In addition to these basic components, the hardware
upgrade may make use of an additional telephone modem or CD-ROM
device.
[0192] An information download hardware upgrade 1001 shown in FIG.
16b allows the subscriber to download large volumes of information
from the operations center 250 or cable headend using a set top
terminal 610. The hardware upgrade 1001 will enable subscribers to
download data, such as electronic books and electronic magazines,
to local storage. Primarily, the hardware upgrade 1001 is an
additional local storage unit 1003 (e.g., hard disk, floppy,
optical disk or magnetic cartridge and may include a microprocessor
1005, instruction memory 1007, and a random access memory 1009, as
shown in FIG. 16b). A small portable viewer may also provided with
the upgrade 1001 to enable downloaded text to be read without the
use of a television.
[0193] The downloadable information may be text or graphics
supplied by the operations center 250 or cable headend. With the
upgrade 1001, electronic books may be downloaded and read anywhere
with the viewer 266. Using the upgrade 1001, electronic books may
be downloaded and stored in compressed form for later
decompression. The electronic books may be decompressed only at the
time of viewing. Important text that the public desires immediate
access may made available through this system. Text such as the
President's speech, a new law, or a recent abortion decision
rendered by the Supreme Court may be made immediately
available.
[0194] In one embodiment, electronic book ordering information is
stored at each set top terminal 610 until it is polled by the cable
headend using a polling request message format. An example of a
polling request message format consists of six fields, namely: (1)
a leading flag at the beginning of the message, (2) an address
field, (3) a subscriber region designation, (4) a set top terminal
identifier that includes a polling command/response (or P/F) bit,
(5) an information field, and (6) a trailing flag at the end of the
message. A similar response frame format for information
communicated by the set top terminal to the cable headend in
response to the polling request may be used.
[0195] FIG. 17 shows components of a set top terminal 610'. The
components include a data receiver 617' and a data transmitter
1011. The data transmitter provides upstream data communications
capability between the set top terminal 610' and the cable headend.
Upstream data transmissions are accomplished using the polling
system described and, using a data transmitter 1011. Both receiver
617' and transmitter 1011 may be built into the set top terminal
610' itself or added through an upgrade module. Regardless of the
specific hardware configuration, the set top terminal's data
transmission capabilities may be accomplished using the hardware
shown in FIG. 17.
[0196] FIG. 17 shows RF signals, depicted as being received by a
data receiver 617' and tuner 613 working in unison. Both of these
devices are interfaced with the microprocessor 1013, which receives
inputs 1015, from the subscriber, either through a set top
terminal's keypad, a remote control unit or viewer 266. Generally,
all cable signals intended for reception on the subscriber's TV are
accessed by the tuner 613 and subsequently processed by the
processing circuitry 1017. This processing circuitry 1017 typically
includes additional components (not shown) for descrambling,
demodulation, volume control and remodulation on a Channel 3 or 4
TV carrier.
[0197] Data targeted to individual set top terminals is received by
the data receiver 617' according to each set top terminal's
specific address or ID. In this way, each addressable set top
terminal 610' only receives its own data. The data receiver 617'
may receive set top terminal 610' specific data in the information
field of the signal frame described or on a separate data carrier
located at a convenient frequency in the incoming spectrum.
[0198] The received data includes information regarding electronic
books and menus available for selection. The subscriber may enter a
series of commands 1015 using a keypad or remote control in order
to choose an electronic book or menu. Upon receipt of such
commands, the set top terminal's microprocessor 1013 instructs the
tuner to tune to the proper frequency of the channel carrying data
and subsequently instructs the processing circuitry 1017 to begin
descrambling of this data.
[0199] Upon selection of an electronic book, the microprocessor
1013 stores any selection information in local memory (not shown)
for later data transmission back to the cable headend. The set top
terminal's microprocessor 1013 coordinates all CATV signal
reception and also interacts with various upstream data
transmission components. Typically, the data transmitter 1011
operates in the return frequency band between 5 and 30 MHZ. In an
alternative embodiment, the frequency band of 10 to 15 MHZ may be
used. Regardless, however, of the frequency band used, the data
transmitter 1011 sends information to the cable headend in the
information field of the response frame described. Those skilled in
the art will recognize that a number of variations and combinations
of the above-described set top terminal hardware components may be
used to accomplish upstream data transmissions.
[0200] VI. Books-On-Demand System
[0201] The electronic book system 200 described may also be
configured in a book-on-demand style. FIG. 18a shows one example of
a configuration for a book-on-demand system. A book on demand
system requires more powerful two-way communications between the
consumer's home, bookstore, school or public library and either the
operations center 250 or a distribution site 1020 such as the cable
headend. In one embodiment, this type of two-way communication can
be provided by the hardware shown in FIG. 17 and described above.
Additional methods related to alternative communication paths are
presented in Section VII.
[0202] Referring to FIG. 18a, in a book-on-demand system, the
subscriber selects the book to be download from an available menu
of books (see for example FIGS. 14d and 14e). The data for menus of
available books is usually sent to the subscriber location by the
distribution site 1020. After the subscriber's menu selection,
information about the subscriber selection (or request) is then
communicated to either a distribution point 1020 (such as a cable
headend) or the operations center 250. Upon receipt of this
request, the needed textual and graphical information for the book
is spooled and sent to the subscriber. In this manner, electronic
books are only sent when requested by the subscriber and are sent
immediately upon demand for the electronic book (or text).
[0203] In order to support such a demand system, the text delivery
and distribution must be conducted on a strong nodal architecture
distribution system, such as, a video-on-demand cable or telephone
television system, through use of individual telephone calls on the
public telephone system or cellular phone system, through the use
of the Internet, or a number of other data network options.
[0204] The book-on-demand system allows for a greater selection of
electronic books to the subscriber and limits the amount of
communicated book data that is unnecessary or unneeded. It also
provides the electronic book to the subscriber in a much timelier
fashion.
[0205] In addition to a stronger distribution system, a
hook-on-demand system requires a distribution point 1020 to have
more sophisticated equipment to access and "spool out" the textual
information. This can be accomplished using file server technology
1024 for storing the books and distribution technology such as ATM
1028 or telephone-type switching `,not shown) to distribute the
textual information. The file server 1024 and distribution
technology that can be used in configuring such a book-on-demand
system is described in U.S. Pat. No. 5,262,875 and U.S. Pat. No.
5,218,695, cited above.
[0206] FIG. 18a shows an embodiment for a book-on-demand system
that utilizes file server technology. In addition to books, the
embodiment of FIG. 18a will support distribution of nearly any
digital data. Books or textual files are received from publishers
282 and other sources through local feeds 1032, ATM 1028, or by
satellite dish 1036, for example. The data is then stored in memory
1040 at the file server 1024. In one embodiment, the distribution
point 1020 is a cable headend that receives requests from
subscribers and delivers text to subscribers over a two-way
communication system (such as a video-on-demand system (VOD)
1044).
[0207] The library 262 can be connected to either a basic
premium-type service cable system 1048, a near video-on-demand type
cable system (or pay-per-view (PPV) 1052) or a video-on-demand
cable system 1044. In connecting with either of these three systems
the library 262 may access the cable directly or may access the
system through a set top terminal 601', 601'', or 601?'.
[0208] Using the two-way video-on-demand system 1044, a subscriber
is able to request a specific book title and receive that text
immediately following its request. To accomplish this, the
distribution point 1020 transmits a list of available books through
the cable delivery system to the library 262. The library 262
displays the list of available books on a menu or similar format.
As described earlier, the librar3, 262 may use menus which list
categories of available books to form its request from the
distribution point 1020. After selecting a book the library 262
then sends a request signal on the two-way communication system
1044 back to the distribution point 1020. This request signal can
be handled in two ways. The library 262 either initiates the
request or the distribution point 1020 polls the various libraries
on to the two-way system 1044. Upon receiving the request for the
book title, the text associated with that book title is transmitted
to the library 262 using the two-way cable system 1044.
[0209] FIG. 18b is an expanded view of an operations center 250
that supports a regional or national book-on-demand system. In
fact, the operations center 250 shown supports distribution of
nearly any digital data. The operations center 250 supports
multiple feeds to receive digital information by tape 1060, 1060',
ATM 1028, or satellite 1036. The information is processed through
an input MUX 1064 and a small file server 1068 before reaching the
master file server 1072. Digital data such as books received from
publishers 282 is then stored on the master file server 1072. The
digital data may be stored compressed in a standard format such as
MPEG2.
[0210] A system controller 1076 provides control over the regional
or national book-on-demand system. Books may be packaged into
groups to provide feeds to various cable headends. In addition,
scheduling and marketing research are conducted at the operations
center 250. In order to handle the scheduling and market research,
book buy data is received at the operations center 250 through a
multiplexer 1082. Book buy information can be provided by the
operation center 250 to the billing and collection system 278.
[0211] The operations center 250 is also equipped to insert
messages or advertisements into the file server. These messages or
advertisements will eventually be received by the subscribers.
[0212] The master file server 1072 uses an output multiplexer 1080
and ATM 1028 as well as satellite connections to distribute digital
data. In one embodiment, cable headends receive text data on books
from the master file server 1080 through the output multiplexer
1028 and an ATM system 1028. After receiving the digital book data,
the cable headends store the books in a local file server 1024.
FIG. 18a's distribution point 1020 is an example of a cable headend
which may receive data from the operations center 250 of FIG. 18b
through an ATM hookup 1088 or satellite hookup.
[0213] VII. Alternative Delivery And Ordering Methods
[0214] Electronic books and related data, including electronic book
menu data, may be books are delivered after an order is received by
the delivery system. The delivery system may supply the electronic
books in real time or near-real time (i.e., near on-demand), or
after a delay period that allows the delivery system to process,
package and transmit the electronic book. Alternatively, the
delivery system may broadcast one or more electronic books in a
continuous fashion. In this alternative, the subscriber indicates a
desired electronic book from a list of the broadcast electronic
books. The delivery system may include a billing system that debits
a subscriber's account, or debits a credit card, for example, upon
delivery of the electronic book. The delivery system, or a related
authorization system, may provide a local authorization code that
allows the subscriber to decrypt, store and view the desired
electronic book.
[0215] a. Use of TV Program Broadcast Delivery System for
Electronic Book
[0216] Delivery
[0217] i. Delivery System Description
[0218] In addition to advances in television broadcast technology,
government regulatory agencies have placed requirements on the
broadcast television industry. In particular, the over-the-air
broadcast television networks will soon transition to high
definition television (HDTV)--a digital broadcast television
standard. These broadcasters may elect to provide a single HDTV
digital signal in their allotted bandwidth, with the remaining
bandwidth used for standard definition television (SDTV) digital
programming. Alternatively, broadcasters may elect to make use of
their bandwidth for data-related services, such as the delivery of
electronic books.
[0219] This embodiment relates to an electronic book delivery
system using a digital television program delivery system. This
embodiment may be used in at least two domains: delivery of
electronic books embedded in the broadcast digital multiplex signal
using terrestrial, over-the-air media; and delivery of electronic
books embedded in the broadcast digital multimedia signal over an
existing cable television system. Over-the-air delivery includes
standard terrestrial television broadcasts. Cable delivery systems
include coaxial cable systems, fiber optic delivery systems, and
telephone delivery systems (including T1 and T3 lines, Integrated
Services Digital Network (ISDN) lines and Asymmetric Digital
Subscriber Lines (ADSL)). In addition, electronic books may be
delivered within the broadcaster's signal by direct satellite
broadcast, by wireless broadcasts, and by other wired means
including local area networks.
[0220] FIG. 19 shows a broadcast television environment 1100 in
which a broadcast program provider, such as a national broadcaster
1110, provides digital multiplex television programming with
embedded electronic book data 1111 to a broadcast affiliate 1112.
The programming with embedded electronic book data 1111 may be
provided to the broadcast affiliate 1112 by any suitable means. For
example, the national broadcaster 1110 may provide the programming
with embedded electronic book data 1111 by satellite transmission
using a satellite broadcast system 1120. The satellite broadcast
system 1120 may include an uplink site 1121, a satellite 1122, and
a downlink site 1123. The satellite broadcast system 1120 may
transmit the programming with embedded electronic book data 1111 to
the broadcast affiliate 1112 and directly to home systems 258',
258'', and 258''' at remote locations such as subscribers' homes,
for example.
[0221] The broadcast affiliate 1112 may provide digital multiplex
television programming with embedded electronic book data 1115 to
intermediate locations such as local cable system 1114.
Alternately, the broadcast affiliates 1112 may provide the
programming with embedded electronic book data 1115 directly to the
subscriber's home systems 258', 258'', and 258'''. The local cable
system 1114 that receives the programming with embedded electronic
book data 1115 may in turn provide the programming with embedded
electronic book data 1115 to the home systems 258', 258'', and
258''.
[0222] The home systems 258', 258'', and 258''' may receive digital
television signals from any device capable of receiving digital TV
signals, including digital televisions, digital set top boxes and
personal computers, or any combination of these devices, or home
subsystems may have a built-in digital TV receiver. The home
systems 258' 258'', and 258''' may receive the programming with
embedded electronic book data 1115 by cable, including coaxial
cable and fiber optic cable, by telephone cable (including T1 and
T3 lines, Integrated Services Digital Network (ISDN) lines and
Asymmetric Digital Subscriber Lines (ADSL)). Alternately, the home
systems 258', 258'', and 258''' may receive the programming with
embedded electronic book data 1111 directly from the national
broadcaster 1110 using the satellite broadcast system 1120. For
example, the home system 258''' receives direct broadcast satellite
programming with embedded electronic book data using a backyard
satellite antenna 1143.
[0223] Also coupled to the home systems 258', 258'', and 258' may
be an Internet 1105. The Internet 1105 provides access to web sites
such as the web site 279. The Internet 1105 may also connect to the
billing and collection system 278, or operations center 250, which
is responsible for formatting and delivering the electronic book
data to the broadcast affiliate 1112 and the national broadcaster
1110 to be embedded into their respective program signals for
delivery. The operations center 250 may use the Internet 1105 to
post electronic book ordering menus, such as provided in the menu
system 851 shown in FIG. 13. The billing and collection system 278
may use the Internet 1105 to receive orders and payment for the
purchases of electronic books. The electronic book ordering menu
851 may be provided as part of the broadcast from the national
broadcaster 1110, the broadcast affiliate 1112, or the local cable
system 1114. Alternatively, the electronic book ordering menu 851
may be downloaded from an Internet web site or alternately viewed
directly on the Internet web site. The use of the Internet 1105 for
these purposes will be described later in more detail.
[0224] In FIG. 19, the national broadcaster 1110 may be a
television program broadcaster. Alternately, the national
broadcaster 1110 may be a radio program broadcaster, or a combined
television and radio broadcaster. The national broadcaster 1110 may
also broadcast any other type of data or communication, either
separately or in combination. Likewise, the broadcast affiliate
1112 may broadcast television or audio or both and may also
broadcast any other data or communication, either separately or in
combination. The national broadcaster 1110 and the broadcast
affiliate 1112 may broadcast analog signals and any type of digital
signals including packet data. Digital data broadcast by the
national broadcaster 1110 and the broadcast affiliate 1112 may
include high definition television and standard definition
television signals.
[0225] FIG. 20 is a flowchart of steps involved in processing text
from the publisher or provider 282 that may occur at the operations
center 250. As shown in step 5500, the publisher 282 processes data
files of text for books, and compresses, encrypts and sends the
data files to the operations center 250. Text files for books may
be sent one book at a time. As shown in step S504, the operations
center 250 receives and processes the data stream from the
publisher 282. Part of this processing may include encryption and
error correction and storage for future delivery purposes. Text
files may be delivered for receipt by multiple home systems
simultaneously, or to a specific individual home system.
[0226] In one embodiment, as shown in step S509, files are broken
into smaller packets of information. Header information is added to
the packets. The bit stream is converted from a serial digital bit
stream to a digital stream that is compatible for insertion into
the broadcaster's video/audio program multiplex signal. Step S513
shows the multiplexing of digital data into the appropriate data
fields, within the video/audio program multiplex. The digital data
may be treated as an ancillary MPEG2 service, being placed into the
multiplex as private data, carried either in the adaptation header
of the MPEG2 transport packets or in a separate transport stream
altogether. Step S513 also shows the operations center 250
performing the necessary modification to the industry standard MPEG
Program Map Table and Program Specific Information.
[0227] ii. In-Home Reception Options for a Broadcast Delivery
System
[0228] FIGS. 21a-21g show reception options at the remote locations
such as at a subscriber's home. In FIG. 21 a, the home system 258
is coupled to a digital set top terminal 1220. The set top terminal
1220 receives the programming with embedded electronic book data
1115 from the broadcast affiliate 1112 or the local cable system
1114. Alternately, the national broadcaster 1110 may provide the
programming with embedded electronic book data by use of the
satellite broadcast system 1120. In this alternative, the set top
terminal 1220 would be coupled to a local, or backyard, satellite
dish antenna or similar device. In yet another alternative, the set
top terminal 1220 receives programming from both the satellite
broadcast system 1120, the local cable system 1114, and directly
from the broadcast affiliate 1112 using terrestrial broadcast.
[0229] Also shown in FIG. 21a is a telephone 1178 that may be used
to communicate with the billing and collection system 278, and a
personal computer (PC) 1172 and a modem 1173 that may be used to
communicate with the Internet 1105. The personal computer 1172 may
be coupled to the set top terminal 1220 using signal path 1174. The
signal path 1174 may include a cable connection such as a RS-232
cable, USB format interface, Firewire interface, and connectors or
by wireless means, such as infrared signaling and radio frequency
signaling, for example.
[0230] The set top terminal 1220 performs the necessary processing
to send the programming with embedded electronic book data 1115 to
the home system 258. The set top terminal 1220 may demultiplex the
programming with embedded electronic book data 1115 and supply the
demultiplexed signal to the home system 258. To do this, the set
top terminal 1220 extracts the data related to the electronic book
from the digital program multiplex signal.
[0231] The set top terminal 1220 may receive commands from a remote
control 1900. The set top terminal 1220 may include communication
devices 1221 that allow reception and transfer of data with
external sources such as the Internet 1105. For example, the set
top terminal 1220 may include a telephone modem, a cable modem, a
wireless modem, a fiber optic connector, a LAN connector, or any
combination of these devices. Using this connection to the Internet
1105, the set top terminal 1220 and PC 1172 may access the billing
and collection system 278 or alternatively connect to the Internet
1105 to access the Internet web site 279 to view electronic book
ordering menus 851 provided by the operations center 250.
[0232] The set top terminal 1220 has input and output ports for
communication with other local and remote devices. Although the
local cable system 1114 or terrestrial broadcast methods are the
most prevalent transmission mediums for delivering programming with
embedded electronic book data to the home, telephone lines
(including T1 and T3 lines, Integrated Services Digital Network
(ISDN) lines and Asymmetric Digital Subscriber Lines (ADSL)),
cellular networks, fiber optics, local area networks, Personal
Communication Networks, and analog and digital satellites and
similar technology for transmitting to the home can be used
interchangeably. The set top terminal 1220 may have output ports
that provide communications from thee set top terminal 1220 to the
home system 258 and a television. Also, the set top terminal 1220
may contain a phone jack that can be used for maintenance, trouble
shooting, reprogramming and additional customer features. The phone
jack may also be used to connect the set top terminal 1220 with the
Internet 1105 for the purpose of ordering electronic books.
Alternately, the set top terminal may support other communication
interfaces using the appropriate interface device connector. The
electronic book data embedded within the programming 1115 contains
data, such as the electronic book ordering menu 851 information, to
advise the subscriber which electronic books are available for
purchase. Once the electronic book ordering menus 851 have been
received by the home system 258, the home system 258 can generate
the appropriate menus. Alternately, menu retrieval or viewing and
electronic book selecting and ordering may be achieved using the
Internet web site 279 on the Internet 1105, which is accessed using
the provided modem interface.
[0233] FIG. 21b shows an alternate arrangement of components for
receiving the broadcast digital programming with embedded
electronic book data 1115 and providing it to a home system 258. In
FIG. 21b, the digital television 1171 is coupled to the broadcast
affiliate 1112 to receive the programming 1115. The digital
television 1171 may also receive the programming with embedded
electronic book data 1115 from the local cable system 1114 or from
the satellite broadcast system 1120.
[0234] The digital television 1171 may include an optional smart
card 1180 that performs the functions described above for the set
top terminal 1220. For example, the smart card 1180 may include a
cable modem, a telephone modem, a wireless modem, a fiber optic
connector, or a LAN connector. Also shown in FIG. 21b is the
personal computer 1172 and the modem 1173, which function as before
to connect to the Internet 1105. The functions of the digital
television 1171 may be controlled by the remote control 1900, using
either infrared signals or radio frequency signals, for example.
Using this connection to the Internet 1105, the television 1171 and
PC 1172 may access the billing and collection system 278 or
alternatively connect to the Internet 1105 to access the web site
279 to view electronic book ordering menus 81 provided by the
operation center 250.
[0235] FIG. 21c shows another arrangement of components for
receiving the broadcast digital programming with embedded
electronic book data 1115. In FIG. 21c, a digital television 1171'
incorporating the smart card 1180 receives the programming with
embedded electronic book data 1115 from the local cable system 1114
and performs all the functions of the library 262 described
previously, including connecting to the viewer 266. The television
1171' could also receive the programming with embedded electronic
book data 1115 using other media including direct satellite
broadcast, fiber optic connections, local area networks, such as an
ethernet, the Plain Old Telephone Service (POTS), other telephone
delivery systems (including T1 and T3 lines, Integrated Services
Digital Network (ISDN) lines and Asymmetric Digital Subscriber
Lines (ADSL)) and by over-the-air broadcast from the broadcast
affiliate 1112. The television 1171', incorporating the smart card
1180, includes some or all of the functionality of the personal
computer 1172 shown in FIG. 21b, for example. The television 1171'
connects to the Internet 1105 and is able to access the web site
279 to view electronic book ordering menus 851 provided by the
operations center 250. The remote control 1900 may be used to
control the television 1171' and library 262. The television 1171'
may also, in its programming, include a soft key board 1174 that is
displayed on the display a the television 1171'. The remote control
1900 can then be used to operate "soft keys" on the soft key board
1174. The television 1171' may also incorporate a separate key
board 1174' that is used to control the television 1171' and the
library 262 and to operate the television 1171' in its personal
computer role. The key board 1174' may be connected to the
television 1171' by a wired connection. Alternately, the key board
1174' may communicate with the television 1171' and library 262 by
wireless means including infrared signaling, radio frequency
signaling and by other optical means including a laser. The
television 1171' and library 262 may connect to a telephone system
using signal path 1154.
[0236] FIG. 21d shows yet another arrangement of components for
receiving the broadcast digital programming with embedded
electronic book data 1115. In FIG. 21d, a digital television 1171'
incorporating a smart card that functions as a complete electronic
book home system 258 receives the programming with embedded
electronic book data 1115 from the local cable system 1114 and
performs all the functions of the home system 258 described
previously, and displays the electronic book data on the television
display. The television 1171' could also receive the programming
with embedded electronic book data 1115 using other media including
direct satellite broadcast, fiber optic connections, local area
network, such as an ethernet, the POTS, other telephone delivery
systems (including T1 and T3 lines, Integrated Services Digital
Network (ISDN) lines and Asymmetric Digital Subscriber Lines
(ADSL)) and by over-the-air broadcast from the broadcast affiliate
1112. The television 1171', incorporating the home system 258
functionality, may include some or all of the functionality of the
personal computer 1172 shown in FIG. 21b, for example. The
television 1171' connects to the Internet 1105 and is able to
access the web site 279 to view electronic book ordering menus 851
provided by the operations center 250. The remote control 1900 may
be used to control the television 1171' and home system 258. The
television 1171' may also, in its programming, include a soft
keyboard 1174 that is displayed on the display of the television
1171'. The remote control 1900 can then be used to operate "soft
keys" on the soft keyboard 1174. The television 1171' may also
incorporate a separate keyboard 1174' that is used to control the
television 1171' and home system 258 and to operate the television
1171' in its personal computer role. The keyboard 1174' may be
connected to the television 1171' by a wired connection.
Alternately, the keyboard 1174' may communicate with the television
1171' and home system 258 by wireless means including infrared
signaling, radio frequency signaling and by other optical means
including a laser. The television 1171' and home system 258 may
connect to a telephone system using signal path 1154.

receiver incorporating the smart card 1180 receives the programming
with embedded electronic book data 1115 from the local cable system
1114 and performs all the functions of the library 262 described
previously, including connecting to a viewer 266. The PC 1172 could
also receive the programming with embedded electronic book data
1115 using other media including direct satellite broadcast, fiber
optic connections, local area network, such as an ethernet, the
POTS, other telephone delivery systems (including T1 and T3 lines,
Integrated Services Digital Network (ISDN) lines and Asymmetric
Digital Subscriber Lines (ADSL)) and by over-the-air broadcast from
the broadcast affiliate 1112. The PC 1172 connects to the Internet
1105 and is able to access the web site 279 to view electronic book
ordering menus 851 provided by the operations center 250.
[0238] FIG. 21f shows another arrangement of components for
receiving the broadcast digital programming with embedded
electronic book data 1115. In FIG. 21f, the PC 1172 with digital TV
receiver incorporating a smart card that functions as a complete
electronic book home system 258 receives the programming with
embedded electronic book data 1115 from the local cable system 1114
and performs all the functions of the home system 258 described
previously. The PC 1172 could also receive the programming with
embedded electronic book data 1115 using other media including
direct satellite broadcast, fiber optic connections, local area
network, such as an ethernet, the POTS, other telephone delivery
systems (including T1 and T3 lines, Integrated Services Digital
Network (ISDN) lines and Asymmetric Digital Subscriber Lines
(ADSL)) and by over-the-air broadcast from the broadcast affiliate
1112. The PC 1172 connects to the Internet 1105 and is able to
access the web site 279 to view electronic book ordering menus 851
provided by the operations center 250.
[0239] FIG. 21g shows another arrangement of components for
receiving the broadcast digital programming with embedded
electronic book data 1115. In FIG. 21g, the home system 258
contains a digital TV receiver 1613 to receive the programming with
embedded electronic book data 1115 from the local cable system
1114. The home system 258 connects to the Internet 1105 and is able
to access the web site 279 to view electronic be ok ordering menus
851 provided by the operations center 250.
[0240] FIG. 22 presents the hardware configuration of a home system
258 to support delivery of electronic books using the TV program
broadcast delivery system. The home system 258 in FIG. 22 includes
a home system front end 259 and home system backend 259'. The home
system front end 259 can vary based on the delivery system from
which electronic book data is being received. The home system
backend 259' and its associated components and functionality are
consistent regardless of the delivery system used and are as
described in Section II above. The home system front end 259
performs several functions, such as receiving digital data
directly, or receiving TV program broadcast signals, and stripping
(or extracting) the data from the signal. Various hardware
configurations may be utilized to achieve the desired functions of
the home system front end 259. For example, as shown in FIG. 22,
the home system 258 can be configured to receive digital program
multiplexes from the set top terminal 1220, from the TV 1171, or
from the computer 1172 using the connector 1617. Alternatively, the
home system 258 can receive the RF channel in which the digital
program multiplex signal is contained using the digital TV receiver
1613 and provide the signal to a digital program broadcast
connector 1617 to extract the electronic book data from the signal.
Finally, the home system 258 can receive a digital data stream,
which has already been extracted from the digital program
multiplex, using a connector 1619. Once the digital data that is
related to the electronic book system has been extracted from the
TV program broadcast signal, the digital data is provided to the
digital logic 609 in the home system 258 for continued processing,
as described in Section II.
[0241] To receive and strip the data from the digital TV program
signal at the consumer's home, the connector 1617 is used. FIG. 23
is a flowchart of processes performed by the connector 1617. The
connector 1617 receives the digital program multiplex signal in
step S1607, removes the MPEG control information from the signal in
step S1608, determines if the stream contains any electronic book
data embedded within it in step S1612, extracts the electronic book
data from the signal in step S1616, and communicates the extracted
electronic book data stream to digital logic components 609 in step
S1620.
[0242] iii. Electronic Book Ordering Process for TV Program
Broadcast
[0243] Delivery
[0244] As described in Section II above, a subscriber selects their
desired electronic book from a menu system. This menu system and
its contents are updated by the operations center 250 using
information delivered to the home system 258 either periodically
distributed over the TV program broadcast delivery system, or
delivered to the home system 258 by the billing and collection
system 278 upon ordering a new electronic book. Order requests for
electronic books made from this menu are forwarded to the billing
and collection system 278 for processing.
[0245] In the case where the delivery is done using a two-way cable
system, the set top terminal 1220 can be used to convey order
request information to the local cable system 1114. The local cable
system 1114 will in turn be in communication with the billing and
collection system 278 or the operations center 250 that handle
requests from the set top terminal 1220 for electronic book
ordering or billing purposes. Further, telephone lines with modems
may be used to transfer information from the set top terminal 1220
to the billing and collection system 278 or the operations center
250. Alternately, the set top terminal 1220 may incorporate a cable
modem, a wireless modem, LAN connectors, T1 and T3 connectors,
Asymmetric Digital Subscriber Line (ADSL) Connectors, Integrated
Digital Service Network (ISDN) connectors or other advanced
communications interfaces for transmitting information to the cable
system 1114 or over alternate communication paths directly to the
billing and collection system 278 or the operations center 250.
Alternatively, the home system 258 may contact the billing and
collection system 278 directly over any of these communication
paths.
[0246] FIGS. 24a-24c show alternate arrangements of an ordering
process that can be used with the programming with embedded
electronic book data 1111 or 1115. In the discussion that follows,
the subscriber receives the programming with embedded electronic
book data 1115 from the local cable system 1114. However, the order
process may also be used when the programming with embedded
electronic book data 1115 is provided by the broadcast affiliate
1112 or the satellite broadcast system 1120, or from any other
entity capable of providing digital broadcast programming with
embedded electronic book data.
[0247] In FIGS. 24a-24c, electronic book order requests may be
provided over a variety of telecommunications media including using
a cable modem to the billing and collection system 278; over a
proprietary two-way transmission system to the billing and
collection system 278; over a fiber optic cable system to the
billing and collection system 278; using a telephone modem to the
billing and collection system 278, using existing telephone lines;
using a cellular modem over wireless telecommunication systems;
using T1 and T3 lines, Asymmetric Digital Subscriber Lines,
Integrated Digital Services Network lines, and using a telephone
and the POTS. Alternately, the electronic book order requests may
also be provided over a LAN, such as an ethernet.
[0248] In FIG. 24a, the national broadcaster 1110 provides the
programming with embedded electronic book data 1111 to the
broadcast affiliate 1112. The broadcast affiliate 1112 sends the
programming with embedded electronic book data 1115 to the local
cable system 1114. The local cable system 1114 sends the
programming with embedded electronic book data 1115 to the home
system 258. To receive the requested electronic book from the
programming with embedded electronic book data at the home system
258, the subscriber may initiate an order request. In the
embodiment shown in FIG. 24a, the subscriber sends an order request
1190 to the billing and collection system 278, which then initiates
the delivery of the requested electronic book data from the
operations center 250 for inclusion in the programming.
[0249] Electronic books may also be received at the home system 258
without the subscriber providing the order request. Another
subscriber may provide an electronic book for delivery to the home
system 258 as a gift, for example. Electronic books also may be
sent to the home system 258 on a trial, or approval basis. For
example, a trial electronic book may be sent to a home system 258
on a trial basis and the trial electronic book could include a code
that prevents viewing after a set, elapsed time from receipt at the
home system 258. To retain viewing privileges for the trial
electronic book, the subscriber could indicate a desire to purchase
the trial electronic book. The operations center 250 would then
return an authorization code that permits the subscriber to retain
the trial electronic book on a permanent basis. Alternatively, the
delivery system 200 could provide a portion of an electronic book,
in an unencrypted format, such as the first chapter, and the
subscriber would have to purchase the electronic book to receive
the authorization code to decrypt the remainder of the electronic
book.
[0250] FIG. 24b shows an alternate arrangement of the ordering
process. The ordering process shown in FIG. 24b differs from that
shown in FIG. 24a in that an order request 1190' is sent to the
billing and collection system 278, which then initiates delivery of
the electronic book data for insertion by the broadcast affiliate
1112.
[0251] FIG. 24c shows yet another arrangement of the ordering
process. In FIG. 24c, an order request 1190'' is sent to the
billing and collection system 278, which then initiates delivery of
the electronic book data for insertion by the national broadcaster
1110.
[0252] b. Operation of the Ordering System Using the Internet
[0253] In the one-way delivery environment typified by the TV
program broadcast delivery environment, the use of the Internet can
provide ubiquitous access to subscribers for ordering electronic
books. The subscriber may log on to the Internet web site 279,
using the PC 1172 of FIG. 21a, 21b, 21e, or 21f, or the television
1171' of FIG. 21c or 21d, or the home system 258 of FIG. 21g. The
subscriber may then enter a subscriber identification. The Internet
web site 279 may then present an individualized menu to the
subscriber. The subscribers may view the individualized menu on the
PC 1172, television 1171' or home system 258, for example. The
individualized menu may be based on subscriber specific data, such
as past electronic books ordered, for example.
[0254] When the electronic book ordering is performed on the
Internet web site 279, the Internet web site 279 may also recognize
the subscriber 285, based on the subscriber's automatic number
identification (ANI), user name, user identification, and Internet
address (i.e., REMOTE._HOST, REMOTE_ADDR, and HTTP_NAME), for
example. The subscriber may also be identified by a unique
subscriber identifier that is provided to the subscriber upon
subscribing to a broadcast television service. Other means for
identifying a subscriber include special features such as browser
cookies. A browser cookie is a mechanism that allows a web site
server to store limited amounts of information on a browser. The
information is typically information sent to a subscriber's
terminal using a Set-cookie HTTP response field header. The
Set-cookie field contains the cookie content as a name/value pair,
and can also contain information explaining when the cookie will no
longer be valid (expires), the Internet domain for which the cookie
is valid (domain), and the path portion of the URL within this
domain for which the cookie is valid. Browsers that understand
cookies will store the data on the set top terminal's hard disk,
for example, and will return these data to the web site server from
which the cookie originated within a cookie request header field.
Cookies are useful for storing state information (when the
subscriber last visited the web site, which resources the
subscriber last used, for example) on the browser, in such a way
that the information is not lost when the subscriber leaves the web
site or shuts down the browser.
[0255] A web site, such as the web site 279, may use cookies to
customize electronic book ordering for the subscriber. For example,
the web site 279 may welcome a subscriber to the web site 279,
based on the information in the cookie, and may navigate the
subscriber to a menu, or individualized menu, based on previous
orders provided by the subscriber. When the subscriber is
identified, the web site 279 may create the individualized order
menu, which the specific subscriber may download to the home system
258.
[0256] Once an order for an electronic book has been made, the
billing and collection system 278 processes the order and initiates
a request to the operations center 250 for the delivery of the
requested electronic book for delivery over the TV program
broadcast delivery system.
[0257] FIG. 25 is a flow chart of the major steps associated with
ordering an electronic book using the Internet. The flow chart
assumes the broadcast environment of FIG. 19.
[0258] The process begins with step S100. In step S110, the PC 1172
of FIG. 21a, 21b, 21e, or 21f, or the television 1171' of FIG. 21c
or 21d, or the home system 258 accesses the web site 279. The web
site 279 may be accessed by entering the address of the web site
279 into a location window of a web browser, by activating a
hypertext link provided on the home system 258 menu or within an
actual electronic book being viewed in the viewer 266, or by
activating a hypertext link received from a different web site. The
process then moves to step S120.
[0259] In step S120, a data signal showing the web site 279 home
page is transmitted to the set top terminal 220, and the web site
279 home page is displayed on the requesting device. The process
then moves to step 5130. In step S130, the web site 279 receives
the order signal 1190 for an electronic book selected by a
subscriber. The order signal 1190 includes an electronic book
identifier and the address and identification of the requesting
home system 258. The process then moves to step S140.
[0260] In step S140, the web site 279 transmits the authorization
request 1196 to the billing and collection system 278. The process
then moves to step S150. In step S150, the billing and collection
system 278 determines if the home system 258 from which the order
signal 1190 originated is authorized to receive the selected
electronic book. The billing and collection system 278 may evaluate
the past credit history of the requesting subscriber. The billing
and collection system 278 may determine if the subscriber's account
is delinquent. If the home system 258 is not authorized to receive
the selected electronic book, the process moves to step S160.
Otherwise, the process moves to step S170.
[0261] In step S160, the billing and collection system 278 sends a
message to the requesting home system 258 stating that the selected
program cannot be accessed, along with the reason for no access.
The process then moves to step S190 and ends.
[0262] In step S170, the billing and collection system 278 sends an
authorization signal 1191 to the operations center 250. The process
then moves to step S180. In step S180, the operations center 250
retrieves and embeds the requested electronic book data within the
programming. The process then moves to step S190 and ends.
[0263] The method of ordering electronic books using the Internet
is not limited to the TV program broadcast delivery embodiment.
This ordering method is general in nature and may be used for
ordering electronic books to be delivered using any of the delivery
methods presented herein.
[0264] c. Internet Delivery Methods
[0265] FIG. 26 is an alternate delivery plan 301' that provides for
electronic book delivery using the Internet. In FIG. 26, the
publishers 282 provide the electronic books to be posted at the
Internet web site 279. The publishers may convert the text and
graphical data to digital format, compress the digital data, and
upload the compressed digital data to the Internet web site 279.
Alternately, the publishers 282 may arrange for an outside
conversion activity 283 to convert the text and graphical data to
digital format. The conversion activity 283 may then provide the
digital data to the Internet web site 279. For example, a large
on-line bookstore could gather publications in electronic form from
a variety of publishers, or could convert hard-copy books to
electronic foul', and post the electronic books on the Internet
such as at the Internet web site 279.
[0266] The electronic books may then be transferred using a public
switched telephone network (PSTN), for example, or other
communications systems, direct to a subscriber 285, a library 286
and a bookstore 287. The library 286 and the bookstore 287 may also
provide electronic books to the subscriber 285.
[0267] When electronic books are provided by the Internet web site
279, the billing and collecting functions may be incorporated into
the Internet web site 279. For example, a subscriber may pay for an
electronic book selection by entering a credit card number into a
data field of a page of the Internet web site 279. In this
configuration, a separate billing and collection system may not be
required. Alternatively, the Internet web site 279 may communicate
information with the billing and collection system 278.
[0268] Electronic book delivery over the Internet may be handled
using a number of methods. In a method, the electronic book may be
downloaded to the requesting home system 258 immediately after the
order has been processed. Alternatively, the electronic book may be
e-mailed to an e-mail address that is entered as part of the
ordering process.
[0269] In another embodiment, as part of the ordering transaction
process, the subscriber is provided with location and authorization
information that allows the subscriber to retrieve the ordered
electronic book at the subscriber's convenience. For delivery of
subscription electronic book products, like newspapers, magazines
or other periodicals, the Internet web site 279 can deliver the
latest version of the product to the subscriber automatically
immediately upon logon by the subscriber to the Internet web site
279. Electronic book data may also be embedded into continuous
multicast streaming video, audio, or data feeds.
[0270] d. Other Delivery Methods
[0271] A number of embodiments for the delivery of electronic books
have been addressed above. This subsection calls out these specific

modular connector 700. A satellite receiver 2903, or other device
capable of receiving a satellite video signal, such as a TV, or PC
with satellite receiver, may process the video signal and deliver
the video signal to the modular connector 700 in the home system
1280, which extracts the embedded electronic book data.
Alternately, the satellite receiver 2903, or other such device, may
extract the embedded electronic book data from the video signal and
provide the data to the modular connector in the home system
258.
[0282] In another embodiment, electronic book data may be embedded
within the audio signal, requiring an appropriate audio-capable
modular connector 700 in the home system 1280 to extract the
electronic book data from the audio signal for processing by the
digital logic 609. In one embodiment, the audio signal is an analog
audio signal. In another embodiment, the audio signal is a digital
audio signal.
[0283] In yet another embodiment, the signal is a spread spectrum
signal containing a digital data stream, requiring an appropriate
spread spectrum receiver modular connector 700 in the home system
1280 to extract the electronic book data for processing by the
digital logic 609. In this embodiment, the spread spectrum signal
is transmitted in the same bandwidth as the video or audio signal,
but below the noise level.
[0284] FIG. 30 presents embodiments associated with the delivery of
electronic books over a wired data network 3001 to a home system
1290. Electronic book data is encoded for delivery by the modular
encoder 2541 and formatted and transmitted by the modular
transmission subsystem 2542. The signal is delivered over the wired
data network 3001. This signal may provide for the dedicated or
non-dedicated delivery of electronic book data. This signal may
also provide for ordering access from the home system 1290 to the
billing and collection system 278 or operations center 250, or the
signal may be a means to provide access to the Internet or other
public network through which electronic books are ordered and
electronic book data is delivered. The wired data network 3001 can
be metallic wire or fiber, supporting any of a number of
communication standards including HDSL, ADSL, DSL, ISDN, T1, T3,
SONET, ATM, X.25, frame relay, Switched MultiMegabit Data Service
(SMDS), or others. The signal sent over the wired data network may
be generated by a data modem or transmission device, in which the
appropriate modem, interface device, or Data Terminating Equipment
(DTE) device is used to receive the signal and provide the embedded
electronic book data to the home system 1290 modular connector 700
for processing. Embodiments of such receiving devices are shown in
FIG. 30 as HDSL modem 3002, ADSL modem 3003, DSL modem 3003, ISDN
Terminal equipment (TB) device 3005, T1 Digital service unit (DSU)
3006, T3 DSU 3007, Fiber user network interface device (UNI) 3008,
ATM UNI 3009, X.25 DTE 3010, Frame relay assembler/disassembler
(FRAD) 3011, and SMDS subscriber network interface device (SNI)
3012. Alternatively, the home system 1290 may contain an internal
modem or DTE 3013, which receives one or more signal types and
provides the received signal with embedded electronic book data to
the home system 1290 modular connector 700 for processing. Finally,
the home system 1290 may be attached to a wired LAN using a
transceiver. In this embodiment, electronic book data may be
delivered over the LAN at any time. One example of how this
embodiment may be used is in a university environment where each
student has an electronic book home subsystem attached to the LAN.
Professors can then deliver textbooks and assignments to selective
students. In each embodiment, the modular connector 700 provides
the embedded electronic book data to the digital logic 609 for
further processing.
[0285] FIG. 31 presents embodiments associated with the delivery of
electronic books using the public switched telephone network (PSTN)
3101 to a home system 1310. Electronic book data is encoded for
delivery by the modular encoder 2541 and formatted and transmitted
by the modular transmission subsystem 2542. The signal is delivered
over the PSTN 3101. This signal may provide for ordering access
from the home system 1310 to the billing and collection system 278
or operations center 250, or the signal may be a means to provide
access to the Internet or other public network through which
electronic books are ordered and electronic book data is delivered.
The signal sent over the PSTN may be generated by a data modem or
transmission device, in which the appropriate modem 3102 is used to
receive the signal and provide the embedded electronic book data to
the home system 1310 modular connector 700 for processing.
Alternatively, the home system 1310 may contain an internal modem
3103, which receives the signal and provides the received signal
with embedded electronic book data to the home system 1310 modular
connector 700 for processing. In each embodiment, the modular
connector 700 provides the embedded electronic book data to the
digital logic 609 for further processing.
[0286] FIG. 32 presents embodiments associated with the delivery of
electronic books using wireless personal communications system
(PCS) 3201 to a home system 1310. Electronic book data is encoded
for delivery by the modular encoder 2541 and formatted and
transmitted by the modular transmission subsystem 2542. The signal
is then delivered over the PCS network 3201. The wireless PCS
system may be, for example, a wireless LAN, digital cellular
telephony network, analog cellular telephony network, digital
cellular radio system, analog cellular radio system, digital pager
network, analog pager network, or Personal Communication Network
(PCN). This signal may provide for the dedicated or non-dedicated
delivery of electronic book data. This signal may also provide for
ordering access from the home system 1320 to the billing and
collection system 278 or operations center 250, or the signal may
be a means to provide access to the Internet or other public
network through which electronic books are ordered and electronic
book data is delivered. A wireless PCS receiver 3202 is used to
receive the signal and provide the embedded electronic book data to
the home system 1320 modular connector 700 for processing.
Alternatively, the home system 258 may contain an internal wireless
PCS receiver 3203 which receives the signal and provides the
received signal with embedded electronic book data to the home
system 1320 modular connector 700 for processing. In each
embodiment, the modular connector 700 provides the embedded
electronic book data to the digital logic 609 for further
processing.
[0287] Returning to FIG. 19, several embodiments are shown
associated with the delivery of electronic books using a national
or local television broadcaster's signal. The signal from the
national broadcaster 1110 can be delivered to the home subsystem
258', 285'', or 258''' using a satellite system 1122, using a
broadcast affiliate 1112 terrestrially, or using a local cable
system 1114. Alternatively, the local television broadcast
affiliate 1112 can originate the signal which can be delivered to
the home system 258', 258'' or 258''' terrestrially, or using a
local cable system 1114. In one embodiment, the video signal is an
analog video signal and the electronic book data is embedded in the
video signal. In another embodiment, the video signal is a digital
video signal and the electronic book data is carried as an
independent data stream. In another embodiment, electronic book
data may be embedded within the audio signal. In one embodiment,
the audio signal is an analog audio signal. In another embodiment,
the audio signal is a digital audio signal.
[0288] In yet another embodiment, the signal is a spread spectrum
signal containing a digital data stream, requiring an appropriate
spread spectrum receiver modular connector, such as the connector
700 of FIG. 32, in the home system 258', 258'' or 258''' to extract
the electronic book data for processing by the digital logic 609.
In this embodiment, the spread spectrum signal is transmitted in
the same bandwidth as the video or audio signal, but below the
noise level.
[0289] Alternatively, several embodiments are associated with the
delivery of electronic books using a national or local radio
broadcaster's signal. The signal from the national radio
broadcaster can be delivered to the home system 258', 258'' or
258''' using the satellite system 1122, or using a broadcast
affiliate 1122. Alternatively, the radio broadcast affiliate 1122
can originate the signal, which can be delivered to the home system
258', 258'' or 258''', terrestrially. In one embodiment, the audio
signal is an analog audio signal and the electronic book data is
embedded in the audio signal. In another embodiment, the audio
signal is a digital audio signal and the electronic book data is
carried as an independent data stream. In yet another embodiment,
the electronic book data is embedded in a sub-carrier of the analog
audio broadcast. In a final embodiment, the signal is a spread
spectrum signal containing a digital data stream, requiring an
appropriate spread spectrum receiver modular connector 700 in the
home system 258', 258'', or 258''' to extract the electronic book
data for processing by the digital logic 609. In this embodiment,
the spread spectrum signal is transmitted in the same bandwidth as
the audio signal, but below the noise level.
[0290] In any of the delivery methods above, the delivery path may
be used to establish connectivity to the Internet, allowing
Internet delivery of electronic book data as presented early in
this section.
[0291] In an alternative delivery embodiment, the electronic book
system can be modified, as was presented in FIG. 15 and discussed
above, to be used at public libraries, schools, bookstores,
newspaper stands or stand-alone kiosks, for example. Public
newsstands for electronic books and periodicals may be conveniently
located, such at the corner store on a New York City street corner,
at an airport, or even on an airplane. The main unit at the public
library, school, bookstore, newsstand, or kiosk may be the file
server 900 as shown in FIG. 15. The file server 900 is a large
electronic memory unit that can store thousands of books,
newspapers, or periodicals. Various electronic storage means may be
used in the file servers, such as hard disks, read-write CD ROMs
and read-only CD ROMs. The controller 908 in FIG. 15 is able to
download books to public viewers 912. The bookstores or libraries
can rent the public viewer 912 to customers with the text for one
or two books loaded onto the public viewer 912. Alternatively, the
customer may own the viewer. The customer returns to the file
server 900 from time to time to receive textual data for a book,
which the customer can read and delete or store permanently on the
customer's own home system 258. Based on the specific information
known about a customer, advertisements contained in the electronic
books may be customized, creating a unique version of the
downloaded newspaper, magazine, or book for each customer.
[0292] Electronic book data also may be delivered as content stored
on physical devices like a floppy disk, magnetic tape, Smart Card
device, Memory Stick device, or any other portable memory storage
device and provided to a subscriber for transfer to the home system
258. Each electronic book memory storage device can contain a
unique identifier, one or more electronic book files, and
associated viewing authorization information. Viewing of any
electronic book file from the memory device may be supported
without restriction. Alternatively, some or all electronic book
files on the memory device may be available for limited viewing or
may require authorization from the billing and collection system
278 prior to being viewed. In this case, the home system 258 may
contact the billing and collection system 278 for authorization
prior to viewing.
[0293] When the electronic book is delivered on a portable storage
medium, such as the Smart Card device or the Memory Stick device,
the electronic book and its storage medium may be packaged in a
manner that protects the storage device, and also provides a
simulation of an actual book. FIG. 33 is an example of a storage
device 2600 that stores an electronic book portable storage medium.
A Smart Card 2601 is held in place in a recess 2602 in a back panel
2603 of the storage device 2600. A front panel 2604 is attached to
the back panel 2603 by a hinge 2605 that is placed at a back spine
2606 of the storage device 2600. The front panel 2604 may be
operated to close over the back panel 2603 to completely cover the
storage medium 2601. The front panel 2604 may incorporate a clasp,
or similar locking device, that engages a corresponding detent 2608
in the back panel 2603 so as to securely close the storage device
2600.
[0294] The front panel 2604 of the storage device 2600 may include
a cover 2609 that replicates a front cover, or dust jacket of a
hard copy book corresponding to the electronic book. Similarly, the
back panel 2603 may include a display similar to that existing on a
back cover, or dust jacket of the corresponding hard copy book. A
cover such as the cover 2609 may be a piece of paper or similar
material that is inserted into the front panel 2604, for example.
Alternately, the cover 2609 may be a permanently fixed replication
of the front cover of the corresponding hard copy book. The
resulting storage device 2600 may thus emulate the corresponding
hard copy book, and may be stored on an actual bookshelf, or other
storage area, in the same manner as the corresponding hard copy
book.
[0295] Electronic book data may also be delivered from a machine or
other device to the home system 258. FIG. 34 shows a system 2700 of
machines 2701 that are coupled by a communications network 2702.
The communications network 2702 may be any wired or wireless system
previously described herein. The communications network 2702 may
also be an electrical distribution system, such as a home wiring
system that is rated at 110 and 220 volts, for example. The system
2700 may include an interface 2703 through which the viewer 266
communicates with the machines 2701. For example, the interface
2703 may be a plug-in device that may be inserted into a 110-volt
wall socket. Such a device 2703 may include a wired or wireless
interface to the viewer 266.
[0296] The machines 2701 may include a microprocessor 2710, a
memory 2711, and a transceiver 2712, which may be incorporated in
VLSI, for example. Included in the memory 2711 may be one or more
electronic books that may be downloaded to the viewer 266, or
otherwise viewed by the viewer 266 using the interface 2703. For
example, a home appliance could include in its memory, an
electronic technical manual related to the home appliance. To
access the electronic technical manual, the viewer 266, through the
interface 2703, may transmit a code or similar "handshake" to cause
the microprocessor 2710 to transmit the electronic technical
manual, using the transceiver 2712, to the viewer 266.
[0297] The electronic book system 200 may also incorporate a book
preview mechanism. Such a preview mechanism may provide the look
and feel of browsing through a selection of books or magazines in a
bookstore. Thus, the subscriber may browse electronic books,
electronic magazines, and electronic newspapers, for example,
before purchasing the electronic books, newspapers or magazines.
Electronic book previews were previously described with respect to
FIGS. 14i and 14j. Such electronic book previews may be provided as
an on-line service, an off-line service, or both.
[0298] The on-line electronic book preview mechanism may use an
Internet web site, such as the web site 279, to display electronic
book previews. To obtain an electronic book preview, the subscriber
may communicate with, or access, the web site 279 using the viewer
266, or one of the other devices shown in FIGS. 21a-21g including
the set top terminal 1220, the personal computer 1172 and the
television 1171, for example. Once in communication with the
Internet web site 279, the subscriber may select an electronic book
preview to view from a list or menu, such as the menu 866 shown in
FIG. 13, for example, of available electronic book previews. The
selected electronic book preview may then be displayed on a web
page of the Internet web site 279, and may be viewed on the viewer,
266, the television 1171 or the personal computer 1172, for
example.
[0299] Other on-line sites may be used to display electronic book
previews. In general, any addressable node, such as an e-mail
address, for example, in a telecommunications network may be used
as a display site for electronic book previews.
[0300] The electronic book previews may also be provided off-line,
to be downloaded to the home system 258, for example. The
subscriber may access the Internet web site 279 and download an
electronic file that includes the electronic book preview. The
electronic book preview may be stored in the library or the viewer,
for example. The subscriber may then view the electronic book
preview using the viewer 266, the television 1171, or the personal
computer 1172, for example.
[0301] When the electronic book previews are provided for
downloading to the home system 258, the electronic book previews
may be provided in encrypted format or in unencrypted format.
[0302] The delivery methods discussed above that allow for
dedicated, full time delivery can be used to provide continuous
distribution of electronic book data including requested electronic
books from subscribers, electronic books to be broadcast to all
subscribers, updated menu contents, and updated advertising. For
the delivery methods discussed above that allow for non-dedicated
or user established connectivity, the operations center 250 may
manage the timing and delivery of content by delivering the
electronic book only when requested, or periodically, to ensure
delivery for those home systems that may not be able to receive the
delivery. Finally, the delivery methods discussed above that are
capable of two-way communication may be used to provide a return
path to the operations center 250 or billing and collection system
278 for the purpose of ordering or requesting updated electronic
book information.
[0303] Additionally, although the home system 258 is presented as
an independent device that directly interfaces with the delivery
system 200, the home system 258 may connect to the delivery system
200 through a set top terminal, TV, PC, radio, or any other device
capable of receiving the signal provided by the delivery system
200. Additionally, the home system 258 may not be an independent
apparatus, having some or all of its functionality supported within
the set top terminal, TV, PC, radio, or any other device capable of
receiving the signal provided by the delivery system.
[0304] e. Alternative Ordering Methods
[0305] Any of the delivery methods described in the section above
are viable embodiments for providing access from the home system
258 to the billing and collection system 278 or operations center
250. In an embodiment, the modular connector 701, as shown in FIGS.
6b and 8, may be used to provide the specific protocol formatting
and transmission processing to allow the home system 258 to use the
communication path. In the embodiment where the PSTN is used to
provide access, the modular connector 701 includes the phone
connector 270 and the modem 611 as depicted in FIG. 6b. In the
embodiment where the cellular phone system is used to provide
access, the modular connector 701 includes the cellular phone or
PCN phone 611' as depicted in FIG. 6b.
[0306] f. Mobile Environments
[0307] A feature provided by the delivery methods using a wireless
broadcast system 2801, satellite broadcast system 2901, wireless
personal communication system 3201, or terrestrial television
broadcast system, is mobility of the electronic book home system or
viewer 266. This mobility allows for ordering and receiving
electronic book data anytime or anywhere, from sitting on a beach
in Florida to sitting on a bus in New York City. This mobility
allows for the delivery of electronic book data subscription
products such as daily newspapers, monthly magazines, or books from
book-of-the-month clubs. These subscription products may be
delivered automatically to the appropriate home system 258 or
electronic book viewer 266. Enhanced end-to-end error correction
techniques can be added to the transmission system to ensure higher
probability of receipt for these mobile environments. Additionally,
transmission methods may be implemented that resend packets of
electronic book data, changing their delivered order on each
resend, to improve likelihood of receipt. For lower bandwidth
mobile environments, an electronic book file may be broken up into
packets and the packets sent a limited number of times. If the
electronic book file is not received completely, the electronic
book viewer 266 may initiate a request to the operations center 250
to resend only that portion of the electronic book file yet to be
received.
[0308] VIII. Electronic Commerce Features
[0309] Electronic commerce features permit users of electronic
books to shop for products and services using an electronic book
viewer. Users can view information about products and services,
electronically purchase them, arid electronically download digital
products. The electronic commerce features also permit tracking of
purchases by particular users and purchases of particular products
for recommending, for example, other products and services to
users. For certain products, such as music and video, a user may
download a sample of the product before deciding whether to
purchase it.
[0310] The processing for providing electronic commerce features is
illustrated in flow charts described below. This processing may be
implemented in software or firmware, including software modules,
for execution by the viewer 266, the library 262, or a combination
of them. Information on products or services may be locally stored
for access by the viewer 266 or the library 262, or accessed and
downloaded via a network such as the Internet using the delivery
mechanisms described above.
[0311] FIG. 35 is a flow chart of a method 3500 for providing
functions for electronic commerce in conjunction with display of an
electronic book. A user selects an electronic book for viewing
using, for example, a displayed menu (step 3502). The viewer 266
displays the electronic book (step 3504) and displays pages of the
electronic book as selected by the user (step 3506). When viewing
the electronic book, the user may enter functions relating to
electronic commerce features using a cursor-control device or other
input device (step 3508) and, in response, the viewer 266 executes
the requested function (step 3510). The viewer 266 continues to
display pages of the electronic book and execute selected
electronic commerce functions until the user closes the electronic
book, as determined by step 3512. If the user selects another
electronic book for viewing, as determined by step 3514, the viewer
266 displays that electronic book (step 3504).
[0312] FIG. 36 is a schematic illustrating a viewer 266 with a
screen 3520 having sections providing for electronic commerce.
Screen 3520 includes a displayed page 3522 of an electronic book,
which may include text, as shown, or other types of information
such as graphics, pictures, or any type of multimedia information.
Page 3522 also includes a task bar 3528 providing sections for
various electronic commerce features, further explained below. The
terms section refers to a definable portion of the screen, and the
phrase task bar refers to a collection of sections for permitting
selection of various commands. A user may select the various
sections by using a cursor-control device to select or "click on"
the section or by entering a particular command using a keyboard or
other input device. The act of selecting a section may involve, for
example, positioning the cursor or a pointer over the section using
the trackball 743 and depressing the selection button 745 to "click
on" the section. Other cursor-control devices, including peripheral
devices, may be used to select a section.
[0313] A menu section 3530 permits a user to access a menu or index
of stored electronic books in order to choose one for viewing, and
examples of such menus are provided in FIGS. 14a-14j. An
information section 3532 permits a user to view information
concerning a particular product or service. A purchase section 3534
permits a user to submit a request to purchase a particular product
or service. A sample section 3536 permits a user to view a sample
relating to a particular product. A catalog section 3538 permits a
user to access an electronic catalog of products and services. A
browser section 3560 permits a user to access a web browser for
retrieving content from the World Wide Web. Page turn sections 3562
and 3564 permit a user to page backward and forward, respectively,
in the displayed electronic book. Task bar 3528 can alternatively
include various other sections for retrieving and manipulating
displayed electronic books.
[0314] Page 3522 also illustrates how an electronic book may
include an identification section 3524 for identifying a particular
product or service. The identification may include a text string,
icon, or other type of symbol. As shown in section 3526, it may
also include a hypertext link. The identification of a product or
service in identification section 3524 may itself be a hypertext
link. The identified product or service may relate to information
in the displayed electronic book. For example, when the user views
a particular electronic book, the viewer 266 may display an
identification of other electronic books by the same author. If the
user views an electronic book on sports, the viewer 266 may display
an identification of sports equipment for purchase. If the user
views an electronic book concerning travel to a particular city,
the viewer 266 may display an identification of entertainment
events for which the user may purchase tickets. These are only a
few examples of displaying products or services for electronic
commerce, and many other possibilities exist.
[0315] FIG. 37 is a flow chart of a method 3570 for displaying
product or service information concerning products or services
selected by a user. A user first selects a product or service
identified in identification section 3524 and then selects
information section 3532. The viewer 266 receives the identified
product or service (step 3572). The viewer 266 retrieves and
displays information concerning the selected product or service
(step 3574). The product or service information may be stored in a
database, such as in library menu 600, and accessed locally or
accessed via a network, such as the Internet, and downloaded using
one or more of the delivery mechanisms described above. In
addition, the viewer 266 may select and display an identification
of related products (step 3576) for potential selection by the
user. The viewer 266 may also optionally select and display an
advertisement (step 3578), the selection of which may be based upon
the product or service selected by the user or other information
related to the user. The advertisements may be targeted to
particular users as described in the co-pending application
entitled "TARGETED ADVERTISEMENT USING TELEVISION DELIVERY SYSTEMS"
and identified above. Upon viewing information about a product or
service, the user may select the purchase section 3534 in order to
purchase a particular product or service. The viewer 266 determines
if the user selects the purchase section 3534 (step 3580) and, if
so, it executes a purchase routine (step 3582), explained below.
The viewer 266 also records statistics (step 3584), as explained
below, in order to record information concerning purchases and
requests for information concerning particular products and
services.
[0316] FIG. 38 is a schematic illustrating a screen 3590 for
display of product or service information in method 3570. Upon
selection of a product or service in conjunction with information
section 3532, the viewer 266 displays an information section 3592
having information concerning the identified product or service.
The information may include, for example, a textual description of
the product or service, features of the product or service, a
photograph or graphical representation of the product or service,
or any type of multimedia information concerning the product or
service. An information section 3594 may display information
concerning related products or services that may be of interest to
the user. The viewer 266 also optionally displays an advertisement
in an advertisement section 3596, the advertisement potentially
being selected based upon information related to the user and thus
targeted to the user. The sections 3592 and 3596 optionally may be
expanded to cover the entire screen of the viewer 266 upon
selection of an expand feature by the user. The user may
subsequently shrink the expanded section to its original size. In
addition, the sections 3592, 3594 and 3596 may incorporate a
feature that allows the user to turn the sections off so that none
or some of the sections are not displayed. This feature may be
available on a page-by-page basis or for an entire electronic book.
The feature may be available in advance of viewing, or only after
the sections have been displayed for a specified time.
[0317] FIGS. 39a and 39b are a flow chart of a method 3600 for
permitting a user to purchase a product or service. Method 3600 is
typically invoked upon a user's selection of the purchase section
3534. The viewer 266 receives an identification of a product or
service (step 3602), which may occur through a user's selection of
a product or service identified in section 3524 or in an electronic
catalog as described below. The viewer 266 determines whether to
automatically generate an order form for the purchase request (step
3604). The viewer 266 typically has stored information concerning
the user, such as the user's name, address, and credit card number.
Also, the viewer 266 receives identification of a product or
service in step 3602.
[0318] Therefore, the viewer 266 can automatically compile the user
information and identified product or service information into an
electronic order form for submission by the user. If auto order
form generation is invoked, the viewer 266 automatically generates
the electronic order form (step 3610) and receives the user's
submission of the electronic order form (step 3612). The user
typically may alter or change the information in the auto generated
form prior to submitting it. Otherwise, if auto form generation is
not invoked, the viewer 266 presents an electronic order form for
completion by the user (step 3606) and receives the user's
submission of it (step 3608). An example of an electronic order
form is described below. The determination of whether to use auto
order form generation may be set by a manufacturer or distributor
of the viewer; alternatively, a user may set that option using a
set-up menu or other mechanism for setting operating parameters of
the viewer 266.
[0319] Upon submission of the electronic order four", the viewer
266 may optionally encrypt the order form and generate a digital
signature for it upon transmission of the form to a server for
order processing (step 3614). If the digital signature is not
valid, as determined by step 3614, the viewer 266 may return an
error message to the user (step 3618). Various types of encryption
are known in the art. Use of digital signatures is described in
copending U.S. application Ser. No. 09/400,296, entitled ELECTRONIC
BOOK SECURITY AND COPYRIGHT PROTECTION SYSTEM, the disclosure of
which is hereby incorporated by reference. Digital signatures may
include a computed digest of an encrypted message, and the digest
is sent with the encrypted message. A recipient decrypts the
digital signature and recomputes the digest from the received
information. If the digests match, the message was received intact
from the sender and is authenticated.
[0320] The viewer 266 may also receive submission of a digital
coupon, if one is available (step 3620). A digital coupon may be
displayed in a section on the viewer 266 and permit a user, upon
selection for submission of it, to receive a discounted price for a
selected product or service. Digital coupons may be time-limited
such that they are displayed using time-based information and are
thus only valid for a particular time period. Other parameters or
criteria may also be used for determining when to display digital
coupons and the content of them.
[0321] In certain situations the viewer 266 may permit a user to
negotiate a price for a product or service. In this case, the
viewer 266 determines if the price received in the electronic order
form is an offered price (step 3622). If it is an offered price,
the viewer 266 or server determines whether to accept the offered
price based on particular criteria (step 3624). For example, the
viewer 266 or server may determine if the offered price is within a
range of acceptable prices and if the user is entitled to a
particular price based upon repeat purchases. The viewer 266 or
server may also determine if rebates or discounts are currently
available for the identified product or service for which purchase
is requested. If the price is accepted, as determined in step 3626,
the viewer 266 displays an indication of the acceptance (step
3630); otherwise, if the price is not accepted, the viewer 266
displays an indication of the non-acceptance and permits the user
to enter another offered price (step 3628).
[0322] The viewer 266, potentially in conjunction with a server,
executes the purchase requested in the electronic order form (step
3632). Payment is attempted using the entered credit card or other
payment-related information (step 3634). If payment is not
approved, the viewer 266 may display an error message (step 3636).
Upon approval of payment, the viewer 266 arranges for delivery of
the product or service (step 3638). For a digital product, the user
can receive the product electronically. A digital product is any
product capable of being electronically stored in digital form;
examples include electronic books, software applications, music,
video, photographs, animations, multimedia information, and slide
shows. The viewer 266 determines if the user purchased a digital
product (step 3640) and, if so, whether the user requested
electronic download of the product (step 3644). If requested, the
product is electronically downloaded to the viewer 266 or library
262 (step 3646). Otherwise, other delivery is arranged and the
viewer 266 provides an indication of the alternative delivery (step
3642). For example, the product may by mailed to the user. The
viewer 266 also records statistics (step 3648), as explained
below.
[0323] FIG. 40 is a schematic illustrating a screen 3650 having an
electronic order form for permitting a user to submit a request to
purchase a product or service as executed by method 3600. Page 3522
presents an electronic order form 3652 upon a user's selection of
purchase section 3534. Electronic order form 3652 may be presented
as an inset image within a displayed electronic book in page 3522,
as an overlayed image in the displayed electronic book, or in place
of the displayed electronic book.
[0324] As shown, the electronic order form 3652 includes sections
for the user to enter information for use in submitting a purchase
request. In particular the electronic order form 3652 includes a
user information section 3654 for user to entered identifying
information such as their name and address. A product/service
identification section 3656 permits a user to enter an
identification of a product or service to purchase. A payment
information section 3658 permits a user to enter a credit number or
other payment-related information. An offered price section 3659
permits a user to enter an offered price, if the user desires to
negotiate a price for the product or service. A digital download
section 3661 permits a user to request digital downloading for
purchased digital products. A submit section 3660, upon selection
by the user, permits the user to submit electronic order form 3652
and its contents for a purchase request. Screen 3650 also
illustrates display of an optional digital coupon in a digital
coupon section 3662 for use with purchase of a corresponding
product or service. The digital coupon may also be displayed in
screen 3520 when the user views a particular electronic book.
[0325] FIG. 41 is a flow chart of a method 3670 for recording
statistics concerning requests to purchase or view information
concerning products and services. The viewer 266 may record these
statistics for use in recommending related products or services to
a user or for selecting particular advertisements for display to
the user. In method 3670, the viewer 266 or a corresponding server
records an identification of a purchased product or service in a
product/service data structure (step 3672) and also records an
identification of the purchased product or service in a user data
structure (step 3674). The viewer 266 optionally records other
information in the product and user data structures such as a time
and date of the purchase, amount of the purchase, quantity of the
purchase, version of a purchased product, and whether the user
entered a purchase request or product/service information
request.
[0326] The product/service data structure can include a table or
series of tables for each product or service, storing information
concerning purchases or requests to view information concerning the
product or service. The user data structure can include a table or
series of tables for each user, storing information concerning
purchases and requests to view product or service information by
the user. The following provides an example of tables for storing
statistics.
TABLE-US-00001 1 product/service 1 number of purchases number of
information requests P(1) product/service 1; purchase 1 amount of
purchase date and time of purchase quantity of purchase version of
purchase . . . P(N) product/service 1; purchase N amount of
purchase date and time of purchase quantity of purchase version of
purchase 1(1) product/service 1; information request 1 time and
date of request . . . 1(N) product/service N; information request N
time and date of request
TABLE-US-00002 1 user 1 purchase request 1 purchase request N
purchase request 1 . . . information request N . . . N user N
purchase request 1 . . . purchase request N Information request 1 .
. . Information request N
[0327] Therefore, tables may exist for each product or service and
for each user to record and store the statistics. A purchase
request for particular product by a particular user, for example,
may be linked to the table storing information for that purchase
request, thus providing a mechanism to cross-reference the
statistics. Use of such linkages using foreign keys is known in the
art with respect to relational database structures. Other data
structures, such as an object-oriented database, may also be
used.
[0328] FIG. 42 is a flow chart of a method 3680 for providing a
user with a sample concerning a product or service. In method 3680,
the viewer 266 receives an identification of a product (step 3682)
and selection of sample section 3536 (step 3684). The viewer 266 or
corresponding server determines if a sample is available for the
identified product, which may be accomplished by accessing an index
of samples cross-referenced with the corresponding products and
services (step 3686). If no sample is available, the viewer 266 can
display an error message (step 3688). If a sample is available, the
viewer 266 retrieves the sample and delivers it to the user (step
3690). The samples may be stored in a database, such as in library
memory 600, and accessed locally or accessed via a network, such as
the Internet, and downloaded using one of the deliver mechanisms
described above. The samples may include, for example, the
following: a video clip (step 3692); an audio clip (step 3694); a
portion of an electronic book such as the first chapter (step
3696); an image (step 3698); a slide show or portion of it (step
3700); an animation (step 3702); or other type of sample (step
3704).
[0329] FIG. 43 is a schematic illustrating a screen 3720 for
displaying a sample concerning a product or service. Upon a user's
selection of sample section 3536, the viewer 266 displays a product
sample section 3722 and presents the requested sample in it. For an
audio sample, the viewer 266 uses speakers to provide the audio
clip and need not necessarily display product sample section 3722.
The audio clip or other audio information may be provided using
speaker/microphone 608.degree..
[0330] FIG. 44 is a flow chart of a method 3730 for providing a
user with an electronic catalog identifying products or services.
The electronic catalog permits the user to shop on-line for
products or services. The electronic catalog may include a static
version in which a user can view information about products and
services, and an interactive version in which the user can order
products or services on-line. In method 3730, the viewer 266
receives a request for an electronic catalog through a user's
selection of catalog section 3538 (step 3732). The viewer 266 or
corresponding server determines whether to provide a custom catalog
(step 3734). If the viewer 266 or server does not provide a custom
catalog, the viewer 266 may alternatively generate and display a
default catalog (step 3736).
[0331] For the custom catalog, the viewer 266 may access the user
data structure storing products or services for which the user has
entered purchase or information requests (step 3738). The viewer
266 determines if the user data structure contains any
identification of products or services previously purchased or for
which information was requested (step 3740). If the user data
structure contains no such identification, the viewer 266 generates
and displays the default catalog (step 3736). A default catalog may
be generated from a sample of products or services based, for
example, upon empirical evidence to determine the most popular
products and services. A manufacturer or distributor of the viewer
may prestore that default catalog or make it available for
downloading into the viewer via a network.
[0332] Otherwise, the viewer 266 retrieves the identification of
the products and services (step 3742) and also retrieves
identification of related products and services (step 3744). The
viewer 266 may include tables or other data structures of related
products or services linked to particular products or services. The
viewer 266 retrieves information for the identified products or
services (step 3746), and compiles the identification of the
products or services and the information into an electronic catalog
(step 3748), which is then displayed to the user (step 3750).
Alternatively, the viewer 266 may generate a custom electronic
catalog by querying the user to determine the user's preferences,
for example, and retrieve products and services based upon those
preferences. The electronic catalog may be displayed as an inset
image within a displayed electronic book, as an overlayed image on
the displayed electronic book, or in place of the displayed
electronic book.
[0333] If the user requests product information through selection
of information section 3532 (step 3752), the viewer 266 executes
product information routine 3570 (step 3754). If the user requests
a purchase of a product or service through selection of purchase
section 3534 (step 3756), the viewer 266 executes purchase routine
3600 (step 3758). The viewer 266 continues to display the
electronic catalog and execute purchase or information requests
until the user closes the electronic catalog, as determined by step
3760.
[0334] FIG. 45 is a schematic illustrating display of an electronic
catalog in a screen 3770. Upon generation of an electronic catalog,
either custom or default, the viewer 266 in page 3522 displays an
interactive electronic catalog in an electronic catalog section
3772, including identification of products or services in sections
3774, 3776, and 3778. Only identification of three products or
services is shown for illustrative purposes; electronic catalog
section 3772 may display more or fewer. The electronic catalog, as
shown, may be displayed within an electronic book, as an inset or
overlayed image, or displayed in place of an electronic book in
page 3522.
[0335] FIG. 46 is a flow chart of a method 3780 for permitting a
user to access and use a web browser in the viewer 266. In method
3780, the viewer 266 receives a user's selection of browser section
3560 (step `1782). In response, the viewer 266 launches a web
browser program (step 3784). Using the web browser, the viewer 266
displays web pages as selected by the user (step 3786) until the
user closes the browser (step 3788). Web browsers are known in the
art and include, for example, the Netscape Navigator program by
Netscape Communications, Inc. and the Internet Explorer program by
Microsoft, Inc. FIG. 47 is a schematic illustrating a web browser
screen 3800 for displaying a web browser 3802 within a viewer 266.
The web browser screen 3800 may be displayed as, an inset image
within a displayed electronic book, as an overlayed image on the
displayed electronic book, or in place of the displayed electronic
book.
[0336] FIG. 48 is a flow chart of a method 3810 for retrieving and
displaying web pages as selected by a user. The user may retrieve
web pages either by using the browser program through selection of
browser section 3560 or by directly selecting hypertext link 3526.
In method 3810, the user selects hypertext link 3526 (step 3812).
In response, the viewer 266 launches web browser 3802 (step 3814)
and, using web browser 3802, retrieves a web page identified by the
hypertext link (step 3816). The viewer 266 continues to display web
pages as selected by the user (step 3818) until the user closes web
browser 3802 (step 3820).
[0337] Upon completion of processing for various electronic
commerce features, as described above, viewer 266 may return by
default to display screen 3520. Alternatively, various other
screens may be used for displaying other information potentially of
interest to the user. The screens may display product and service
information, and potentially other information, using a wide
variety of types of content, including multimedia information, for
enhancing a user's experience in interacting with the viewer and
the ease with which the user may use the various electronic
commerce features.
[0338] A variety of electronic commerce features have been
described for obtaining information concerning products or services
and purchase of them. Also, a variety of delivery mechanisms,
systems and methods have been described for ordering and delivery
of electronic books. One of ordinary skill in the art will
recognize that the above description is that of exemplary
embodiments of the invention and that various changes and
modifications may be made thereto without departing from the scope
of the invention as defined in the following claims and equivalents
to them.
