entitled SYSTEM AND METHOD TO FACILITATE PROGRAMMING OF AN
ASSOCIATED RECORDING SYSTEM. The entireties of these applications
are incorporated herein by reference.
TECHNICAL FIELD
[0002] The present invention relates to a system and method to
facilitate selection of an audio and/or visual program having a
token that may be employed to program operation of an associated
audio/visual system.
BACKGROUND OF THE INVENTION
[0003] In order to see a list of currently scheduled programs and
to select which programs to watch, television viewers may employ
printed television guides, such as appear in daily newspapers or
weekly magazines. Cable television systems often include a channel
with a video broadcast corresponding to the printed program guide.
The cable channel displays listings of programs appearing on the
different available channels over a fixed number of time slots. The
listings are commonly arranged in a grid, in which the various
scheduled programs or shows are arranged within rows and columns,
indicating the channels and times at which they can be found. The
grid is continuously scrolled vertically so that a viewer may scan
a continuously refreshing set of programs within the displayed time
slots.
[0004] Users of conventional television and cable systems often
employ video tape recorder ("VTR") systems to implement a
non-commercial time-shifting function of desired programs. In this
way, an individual is able to record a program that the individual
is unable to view as it is being broadcast and watch the recorded
program at a more convenient time. The VTR system includes a user
interface through which the individual enters programming
information defining the time, channel, and duration corresponding
to a selected program that is to be recorded.
[0005] One type of VTR system employs a feature (known as "VCR
Plus") that enables a user to record a pre-selected program by
entering a unique program identification number associated with a
specific program. The program identification number, which may be
found in a printed television listing, corresponds to programming
information (e.g., channel, time, duration) that is set by the VTR
to record the particular program when it is broadcast.
[0006] More recently, satellite, Direct TV, or cable distribution
systems are employing interactive electronic program guides
("EPGs") which function somewhat similarly to the broadcast program
listing channels described above. Rather than scrolling
automatically, however, an EPG allows a viewer to employ a remote
control device to scroll, as desired, through an interactive
program grid. The EPG is typically implemented in software, which
runs on a set-top box connected to a TV and a system input. When
scrolling through the EPG, the set-top box inserts the appropriate
programming information into each new row or column. The
programming information is typically cached at the set-top box, and
is updated by the system's headend by employing an appropriate
communications path. The updating of program information may be
implemented, for example, utilizing two-way communications
capabilities of interactive cable or satellite systems or another
communications path, such as by employing a modem to communicate
over a conventional telecommunications network.
[0007] In order to remain competitive in the home entertainment
industry, manufacturers and service providers are increasing
efforts to develop improved entertainment systems. A rapidly
evolving type of entertainment system relates to a personal video
recorder ("PVR") system. A PVR system includes a large digital data
storage device, such as a hard disk drive, for storing recorded
audio and/or video programming in a digital format (without a video
tape). The storage device enables a viewer to efficiently implement
a time-shifting function so that the view can watch the recorded
program at a more convenient time. The PVR system receives
broadcast programs from a service provider, such as in the form of
cable television, satellite, or another source of programming. The
PVR system also may employ a video compression system (e.g., an
MPEG-2 format) in combination with an analog-to-digital converter
for converting analog broadcast signals into a suitable digital
format. Alternatively or additionally, the PVR system may receive
broadcast signals in a digital format.
[0008] A PVR typically records a program based on program criteria
selected from an interactive on-screen listing, such as provided by
an associated interactive EPG. An EPG is typically implemented in
software, which runs on a set-top box connected to a television and
a system input. When scrolling through the EPG, the set-top box
inserts the appropriate programming information into each new row
or column. The programming information is typically cached at the
set-top box, and is periodically updated by the system's headend
over an appropriate communications path. The updating of program
information may be implemented, for example, utilizing two-way
communications capabilities of interactive cable or satellite
systems or another communications path, such as by employing a
modem to communicate over a conventional telecommunications
network. However, the programming only provides programming choices
according to the information downloaded to the PVR system.
[0009] A PVR system further may provide enhanced recording
capabilities and enhanced television functionality. By way of
example, a PVR system may include a virtual pausing function, such
that a user may pause a live broadcast for a period of time while
the PVR continues to record the live broadcast. The user may then
continue watching from the point that the pause was initiated while
the PVR continues to record the live broadcast. Other available
features may include fast-forwarding through recorded programming,
rewinding parts of recorded programming, skipping ahead through the
recorded programming, as well as other enhanced television
functionality.
[0010] Another feature of a PVR system relates to intelligent
recording of programming. One example of intelligent recording
enables a user to program one or more keywords that are searched
for on the EPG program listings stored at the PVR. The PVR, in
turn, automatically records shows that match the search criteria.
Another recording method enables a user to select a particular
program to record all future broadcast episodes of that program.
Commercially available PVR systems include, for example, TiVO.TM.,
ReplayTV.TM., and WebTV.TM..
[0011] By way of example, a WebTV-based system employs a standard
television set as a display device for browsing the World Wide Web
(the "Web") and is able to connect to the Internet using a standard
telephone, DSL (Digital Subscriber Line), Cable Modem, wireless
data communications (e.g., satellite or fixed wireless), or another
similar communication path. A user of a WebTV system employs a
client system that includes a set-top box having hardware and
software for providing a graphical user interface (GUI), such as
including an EPG, by which the user can browse the Web, send email,
and access other Internet services. The client system utilizes a
television set as both a display device and an audio output device.
The set-top box is coupled to the television set by a link for
communicating audio and/or visual information to the television.
The client system also includes a remote control (e.g., an infrared
remote control device) that a user employs to control the system
to, for example, browse the Web and perform other functions, such
as to provide enhanced television or satellite capabilities. A
WebTV-based (or other similar) client system may also include a
digital recording device to enable a user to record selected
programs and provide other enhanced features while viewing a
program, such as described above.
[0012] As the available bandwidth for broadcast program continues
to increase, service providers are continuing to increase the
number of programming channels from which to choose. As a result, a
conventional EPG running on a PVR system may not provide a
completely satisfactory mechanism to sort through and select
programs.
SUMMARY OF THE INVENTION
[0013] The present invention provides a system and method to
facilitate selection and programming operation of an audio/visual
system, such as to record a predetermined audio/visual program when
it is broadcast. The system includes a local computer (e.g., a PC,
a PDA, etc.) that may connect to a server system through a network
infrastructure, such as the World Wide Web (the "Web"). The server
system, for example, includes a searchable database, which may be
accessed as a website, including information about numerous audio
and/or visual programs (e.g., sports programs, movies, situation
comedies, news shows, educational programs, etc.). The local
computer is programmed to connect to the server system for
searching and/or filtering through the program information of the
database.
[0014] A user may employ the local computer to select one or more
programs and have a token assigned to one or more recipients (who
also may include the user) representing program criteria for each
selected program. Each recipient may obtain the assigned token. For
example, a recipient may employ the local computer to obtain the
token. The token may be provided to the local computer, such as
part of an electronic mail ("email") message or it may be
downloaded to the local computer from the server. Alternatively or
additionally, a token may be received at the local computer from
another remote computer by any data communications mechanism. Each
token includes program criteria representing a specific audio
and/or visual program in a known format that may be employed to
program a recording system to record a corresponding broadcast
program based on the corresponding token.
[0015] Another aspect of the present invention provides a system to
facilitate selection of at least one of audio and visual program.
The system includes a first computer operative to connect to a
second computer for filtering through a plurality audio and/or
visual programs based on selection criteria to provide a filtered
representation of one or more programs. A program from the filtered
representation of programs is selectable at the first computer so
as to cause a token indicative of the selected program to be
assigned to a recipient. The token represents the selected program
with sufficient particularity to program a recording system to
record the program represented by the token based on the associated
token.
[0016] Still another aspect of the present invention provides a
system to facilitate selection of at least one of audio and visual
program. The system includes a first computer programmed provide a
first signal to a second computer for instructing the second
computer to sort through information related to a plurality audio
and/or visual programs. The first computer receives a second signal
from the second computer indicative of a filtered representation of
programs, the first computer being operative to provide a third
signal to the second computer for causing a message having an
associated token to be assigned to a recipient. The assigned token
represents at least one of an audio and visual program of the
filtered representation of programs so as to enable the recipient
thereof to program a recording system based on the associated token
to record the program represented by the token.
[0017] Still another aspect of the present invention provides a
computer-readable medium having computer-executable instructions
for filtering through information at a server system in response to
a request from a remote computer to provide a filtered
representation of one or more audio and/or visual programs. A
message is assigned to a recipient having an associated token based
on the filtered representation, which token includes program
criteria sufficient to program a recording system to record a
predetermined program represented by the token based on the
token.
[0018] Another aspect of the present invention provides a method
for facilitating programming of an associated device. The method
includes selecting at a remote computer a program from program
information provided by a server system identifying one or more
audio and/or visual programs. A message is assigned to a recipient,
the message having a token that represents the selected program
with sufficient particularity to program a recording system to
record the program represented by the token based on the token.
[0019] To the accomplishment of the foregoing and related ends,
certain illustrative aspects of the invention are described herein
in connection with the following description and the annexed
drawings. These aspects are indicative, however, of but a few of
the various ways in which the principles of the invention may be
employed and the present invention is intended to include all such
aspects and their equivalents. Other advantages and novel features
of the invention will become apparent from the following detailed
description of the invention when considered in conjunction with
the drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0048] The present invention relates to a system and method to
facilitate selection of audio and/or visual programs that, in turn,
may be employed to program an associated recording system. Briefly
stated, the system includes a local computer operative to connect
to a server system through a network infrastructure, such as the
World Wide Web (the "Web"). The local computer is programmed to
search and/or filter through audio and/or visual program
information in the searchable database. A token representing a
specific one of the programs may be obtained (e.g., received as
email or downloaded or obtained by other data communication means)
based on selecting one or more programs from the filtered
information.
[0049] In the following description, for purposes of explanation,
numerous specific details are set forth in order to provide a
thorough understanding of the present invention. It will be evident
to one skilled in the art, however, that the present invention may
be practiced without these specific details. In other instances,
well-known structures and devices are shown in block diagram form
in order to facilitate description of the present invention.
[0050] Turning now to FIG. 1A, a functional block diagram of a
system 1 to facilitate programming of a recording system 2, in
accordance with an aspect of the present invention, is illustrated.
The system 1 includes a program selection system 4 for selecting
one or more audio and/or visual programs. The program selection
system 4 may communicate information identifying the selected
program to the recording system 2 through a transport system 6. The
system also may include a token service system 8 for, if needed,
processing program information, which may be a token, into a more
appropriate form to program the recording system to record each
selected audio/visual program. The token service system 8 may
receive program information from the program selection system 4
directly, from the transport system 6 during transport to the
recording system 2, and/or from the recording system 2 via the
transport system.
[0051] The program selection system 4 may include a resource or
service for selecting audio and/or visual programs that may be
recorded at one or more recording systems 2 in accordance with an
aspect of the present invention. By way of example, the program
selection system 4 may include an EPG, which may be local or remote
relative to the recording system 2. One or more Website services
also may operate as program selection systems 4, such as may be
provided by any third party, including network broadcasters, MSOs,
telephone service providers, publishers, etc.
[0052] The program selection system 4 may be implemented in
conjunction with an electronic appliance operable to communicate
with a Web-based service, such as, for example, a telephone (wired
or wireless), a personal computer (PC) (e.g., handheld, desktop,
portable, etc.), a roaming PC, a PDA, the recording system 2, or
any other suitable electronic appliance.
[0053] In addition to a user selecting programming, such as with an
EPG or Web-based service, the program selection system 4 also may
include a subscription service that automatically sends to the
recording system 2 information identifying program selections made
by the subscription service. The subscription service could be an
individual, a group of persons, or an organization to which a user
has subscribed and provided sufficient information to enable the
subscription to send program information to the subscriber and/or
directly to the recording system 2 identified by the subscriber,
such as through the transport system 6.
[0054] Program information identifying one or more selected
programs, such as in the form of tokens, also may be communicated
via email or any other data transport mechanism. The message
containing a token may be sent to a user or directly to an address
associated with the recording system 2, such as through the
transport system 6. The message and/or tokens further may
communicated to any other address, such as from the recording
system 2 or another device (e.g., a remote computer or PDA).
[0055] As just described, the transport system 6 facilitates
communication of selected programming information to and/or from
the recording system 2. Advantageously, the transport system 6 may
include any type of transport medium or communications
infrastructure to effect programming of the recording system 2 in
accordance with an aspect of the present invention. By way of
example, the transport system 6 may utilize email, TCP/IP,
universal plug-n-play (UPNP), phone dial-up to and/or from the
recording system 2, addressability through a satellite and/or cable
service provider (MSO), or any other type of communication capable
of communicating a token and/or other information to the recording
system 2.
[0056] The token service system 8 is operable to convert (or
translate) program information into a useable format, which may be
employed to program the recording system 2 to record a selected
program in the tuning space associated with the recording system
based on the program information. The program information, for
example, may include a universal program identifier (UPID) that
identifies a specific program that is scheduled to be broadcast
(which broadcast particulars may differ according to the local
tuning space). Alternatively or additionally, the selected program
information provided to the token service system 8 may include a
general purpose program identifier (GPID). A GPID may be utilized
to identify a program, such as by identifying attributes indicative
of the program. The program attributes, for example, may include a
title, director, producer, actors and/or actresses, plot, genre,
category, year, etc.
[0057] As mentioned above, the program selection system 4 and/or
the recording system 2 may provide the program information to the
token service system 8. The token service system 8 may convert the
received program information, such as may include a UPID, a GPID,
and/or any other identifying information for a program into
scheduling data (e.g., date, time, and channel) sufficient to
program the recording system 2 to record the identified program.
The translation at the token services system 8, for example, may be
based on stored profile data for the recording system 2 or,
alternatively, the program information or associated information
(e.g., zip code and service provider information or other data
identifying configuration requirements for a recording system) may
provide sufficient details about the recording system 2 and local
tuning space to enable retrieval of appropriate details for
programming the recording system to record the selected program.
Desired local tuning space and scheduling data may be stored in one
or more scheduling databases that may be associated with the token
service system 8.
[0058] Various types of services also may be associated with the
token service system 8. One related service, for example, may
include links to related types of media or events. Another type of
related service may store program selections (e.g., made with the
program selection system) corresponding to programs not yet
scheduled to be broadcast. An associated token service could be
programmed to provide the appropriate local programming information
to each respective recording system 2 after the program has been
scheduled to be broadcast and corresponding scheduling information
has been stored in the corresponding scheduling database. Moreover,
a token service associated with the token service system might
enable dynamic broadcast programming. That is, a broadcaster or
network might adjust its broadcast schedule to include a particular
program in response to receiving a sufficient number of program
selection requests for the program even though it was otherwise not
scheduled. Advantageously, the broadcast may occur at off-peak
times so as not to interrupt regularly scheduled programming, as
the recording system 2 provides an efficient means to time shift
broadcast programming.
[0059] The token service system 8 further may be employed to
monitor token translations and store corresponding demographic
and/or marketing information. This information may, in turn, enable
a variety of other associated services, such as rating systems,
subscription services identifying or sending tokens to recording
systems 2, indicative of the most watched (or recorded) programs,
etc.
[0060] The recording system 2 may include any type of recording
device, analog or digital, and a communications link for receiving
tokens and/or program information based on which the recording
system may be programmed to record one or more identified audio
and/or visual programs. For example, the recording system 2 may
include a digital video recorder (DVR) for selectively storing
broadcast audio and/or visual programs. The recording system 2 also
may include more than one tuner to help avoid programming conflicts
that might occur, such as being capable of recording more than one
program concurrently. Moreover, the recording system may be capable
of recording programs from one or more broadcast medium (e.g.,
cable television, satellite, HDTV, conventional broadcast, radio,
etc.). The recording system 2 may be addressable for receiving
program information via the transport system 6, which program
information may be provided by the program selection system 4
and/or the token service system 8, such as described above.
[0061] It is to be understood and appreciated that the translation
of the received program information into the appropriate local
program information could be implemented at the recording system 2
or at a system local to the recording. For example, the recording
system 2 may regularly (periodically or intermittently) receive
local tuning space data, which data may be stored locally in a
tuning space database. The local tuning space database may, in
turn, be accessed to convert received program information into more
specific scheduling information based on the source(s) of
programming and configuration at the recording system 2.
[0062] Moreover, the recording system 2 may be programmable to
employ storage management to facilitate storage of programs. For
example, the storage medium of the recording system may be
partitioned, with each partition being separately addressable via
the transport system 6. In this way, the recording system 2 may
provide separate storage space for different individuals and/or
different types of programming.
[0063] By way of example, a user may access a Website by employing
a computer, such as a PDA (Personal Digital Assistant), a portable
PC, a desktop PC, etc., and see an interesting article for an
upcoming movie. The user may obtain a token corresponding to the
movie. The token may include a GPID and/or a UPID or other data
identifying the movie. The user may employ the computer to, in
turn, effect programming of a recording system and/or send the
token to one or more individuals that the user believes may be
interested in recording the movie.
[0064] The token service system may translate the token to the
appropriate local tuning space based on identifying information
associated with the user, such as may be stored in a cookie or
another user ID. The associated scheduling information may be
communicated to the recording system identified by the user.
However, in the event that program has not yet been schedule in the
local tuning space for the identified recording system, appropriate
data may be stored for subsequent communication of the scheduling
data to the recording system after the scheduling information
becomes available. Each individual receiving a token further may
utilize the token to program an authorized recording system and/or
forward the token to other people.
[0065] FIG. 1B illustrates a block diagram of an infrastructure or
system 10 according to one aspect of the present invention. By way
of example, the system 10 includes one or more servers 20 that
provide a portal to program criteria that may be selectively
obtained and, in turn, employed to program operation of a recording
system. The server 20 may provide network services, such as storing
information, including program characteristics, links to
program-related information, tokens, etc., for numerous audio
and/or visual programs. The services provided by the server 20 may
be used in conjunction with software running in the remote computer
30 and/or each of a plurality of client systems 40a, 40b, and 40c.
The services enable a user thereof, for example, to browse the Web,
search and obtain information content contained on the server, send
and/or receive electronic mail, and to make use of the Internet in
various other known ways. The system 10 also may include one or
more other servers 50, which also may provide electronic mail or
other Internet-based services, as is known in the art.
[0066] By way of example, one or more of the other servers 50 may
be a third party service provider that cooperates with the server
20 to facilitate remote programming of a client system 40 (e.g.,
the user's own or another individual's PVR) in accordance with an
aspect of the present invention. A user may access services, such
as may be associated with a Website, provided by the server 50 and
select one or more desired audio and/or visual programs, such as by
clicking on an associated icon with a user input device.
[0067] The server 50 may, in turn, send a corresponding request to
the server 20 or another of the servers 50, which request may
include a token identifying the selected show and user information.
The user information, for example, may include a user ID and/or
other data (e.g., a cookie) from which the server 20 may determine
more specific identifying information associated with the user's
client system (e.g., information about the broadcast
services--cable, satellite, broadcast television, etc.) and/or the
user. By way of example, the user ID information further may
include a global identifier for the user, similar to the
Passport.TM. and Wallet.TM. services provided by the Microsoft
Corporation of Redmond, Wash. That is, another of the servers 50
may correspond to a server (e.g., a passport server) that provides
a Wallet.TM./Passport.TM. type of service, which facilitates
roaming. For example, the server 50 can communicate to the server
20 desired information about the user's (or another person's)
client system 40a, such as a PVR ID, zip code, service provider
information, etc. in response to the request to the user's
selection. Alternatively, the server 50 that provides the service
where the user made the selection may send information to the
server 20 via the Internet 60 or another communications link
sufficient to identify the user and/or a client system associated
with the user. In response to the identifying data from the server
50, the server 20 may locate local programming information, such as
may be stored in a broadcast content database for each selected
program. The server 20, in turn, may pass the programming
information directly to the user's client system 40, which
automatically programs itself to record each audio and/or visual
program selected by the user.
[0068] Each of the client systems 40a, 40b, and 40c (hereinafter
collectively referred to as "client systems 40") is located
remotely from each server 20 and 50. While, in the example of FIG.
1B, the remote computer 30 is illustrated as being separate from
each client system 40, it is to be understood and appreciated that
the remote computer may be integrated into or operatively connected
to an associated one of the client systems 40a, 40b, and 40c. For
purposes of brevity, FIG. 1B illustrates three client systems 40a,
40b, and 40c and one remote computer 30, although it is to be
appreciated that a greater number of client systems and remote
computers may be in the system 10.
[0069] The remote computer 30 is connectable to a conventional
network infrastructure, such as the Internet 60, through an
associated communications infrastructure 70. The communications
infrastructure 70, for example, is a modem bank associated with an
ISP (Internet Service Provider). As mentioned above, the remote
computer 30 may be employed to browse a website and/or search for
programs matching selection criteria provided by a user or by a
service provider. The servers 20 and/or 50 may comprise multiple
physical and logical devices connected in a distributed
architecture. Each client system 40 and the remote computer 30
further may connect to the servers 50 and 60 either through a
direct data connection (not shown) (e.g., telephone, DSL, Cable
Modem, wireless data communications, ISDN, etc.) or through the
Internet 60 via its associated communications path.
[0070] Each client system 40, for example, is an entertainment
appliance programmed and/or configured to receive audio and/or
visual programs content in a predetermined format. Examples of
signal formats include analog television (cable, satellite, etc.),
digital television, or other formats. Examples of systems employing
such standard formats that may be implemented in a system, in
accordance with the present invention, include Direct Satellite
Systems ("DSS"), Advanced Television ("ATV") systems, Digital
Television ("DTV") systems, Video-on-Demand, MPEG over ATM
Networks, High Definition Television ("HDTV"), cable (e.g., DVB-C)
etc. audio and visual programming from a source of programming.
[0071] Each client system 40 also may be programmed and/or
configured to connect to connect to the Internet 60 and employ a
standard television set as a device for browsing the World Wide Web
("the Web"). The connection between each client system 40a, 40b,
40c and the Internet 60 is made through a respective communications
link or data connection 80a, 80b, 80c. A communications link may
be, for example, a standard telephone, DSL, ISDN (Integrated
Services Digital Network), or other similar communications path. In
the example of FIG. 1B, communications links 80a and 80b connect
the client systems 40a and 40b, respectively, to the Internet 60
through a common communications infrastructure 84, such as a modem
pool at an Internet Service Provider ("ISP"). The communications
link 80c connects the client system 40c to the Internet 60 through
another communications infrastructure 90 such as, for example,
another ISP or a private Internet server.
[0072] Each client system 40 may have one or more email addresses
associated therewith. As a result, a remote device, such as the
remote computer 30, having email capabilities may, in turn,
communicate with any of the client systems 40 via email in a
conventional manner. For example, each person in a given family may
have a different email address associated with a common client
system 40a for receiving email. A component or subsystem (e.g., a
digital audio/video recording system) of the client system 40a also
may be provided with its own email address (or addresses) for
receiving program instructions or other pertinent control
information via email, such as in the form of an attachment or an
object embedded in the email. The remote computer 30 may be located
remotely from the client systems 40, although it may be located in
generally the same physical location (e.g., an individual's home)
as one of the client systems.
[0073] FIG. 2 illustrates a block diagram of an illustrative client
system 40a in accordance with an aspect of the present invention.
By way of example, the system 40a includes a set-top box 100. The
box 100 includes hardware and software for providing the user with
a graphical user interface ("GUI") by which the user can browse the
Web, send email, access other Internet services, and control other
functions of the system 40a. The client system 40a also includes an
ordinary television set 110 (or other type of display device) and a
remote control device 120, which may be used to control the set-top
box and/or the television. Alternatively, the box 100 may be built
into the television set 110 to form an integral unit.
[0074] The client system 40a may employ the television set 110 as
both a display device and an audio output device, although a
supplemental audio system may be operatively connected to the box
or the television for providing an additional audio source. The box
100 is coupled to the television set 110 by a link 130. The link
130 includes an audio channel (digital and/or analog) for
generating sound from the television's speaker and a video channel,
such as an RF (radio frequency), fiber optic, S-video, composite
video, component video, or other suitable form of video
channel.
[0075] The box 100 also is coupled to one or more sources of audio
and/or visual broadcast programming 140 by a connection 150. In the
example of FIG. 2, the broadcast programming source is illustrated
as an antenna for receiving programming signals transmitted through
free space, such as in the form of satellite, conventional
broadcast television, or high definition television signals (analog
or digital). It is to be appreciated that the box 100 may be
programmed and/or configured to receive audio and/or visual
programs from other types of programming sources, such as cable
television or Internet audio/visual streaming, such as in
accordance with any broadcasting format. Moreover, different
programming sources also may be combined to provide a broader
programming selection. The audio-visual source 140 provides a
signal to the set-top box 100 via a connection 150. The signal may
be digital or analog, with the set-top box 100 being appropriately
programmed and/or configured for processing the signal received via
the connection 150.
[0076] The set-top box 100 also is connectable to a communications
link 42 or 44 (FIG. 1B) via a bi-directional connection (or data
link 80a) 160. The connection 160 may be in the form of a
conventional telephone network (POTS, i.e., Plain Old Telephone
Service), ISDN, DSL, Cable Modem or other suitable data connection.
The extent of the connection 160 may be intermittent, continuous
and/or user defined. The box 100 also may be connected to a power
supply (not shown) for receiving an appropriate electrical
energy.
[0077] A user employs the remote control 120 in order to control
the client system 40a, such as to browse the Web and perform other
functions. The box 100 receives commands from remote control 120
via a wireless communications link 170. The communications link
between the box 100 and the remote control 120, for example, is an
infrared ("IR") communication link, although any other suitable
type of link may be used, including a wired link (e.g., an
electrically conducting or fiber optic cable). A control panel (not
shown) also may be built into the set-top box 100 for controlling
operation of the client system 40a.
[0078] Referring now to the internal contents of the box 100, the
box includes a processor 180, which is coupled to a bus 190, for
controlling the internal operation of the box and peripheral
devices coupled to the box. The functions performed by the box 100
under the control of the processor 180 may result from software
instructions executed by the box 100 and/or from operation of
hardwired circuitry. In addition, the bus 190 may represent
multiple physical buses connected by various bridges and/or
adapters, the details of which are not required for an
understanding of the present invention.
[0079] The box 100 also includes a receiver/tuner 200 (digital or
analog) for receiving and decoding the audio and/or visual programs
received from the source 140 via connection 150. By way of example,
the receiver/tuner 200 may be programmed and/or configured to
receive and decode signals in at least one of several data formats
(e.g., based on the MPEG standard, the NTSC standard, broadband,
etc.). The receiver 200 is coupled to the bus 190, such as for
receiving instructions identifying which channel or channels to
decode. The receiver also provides a digital output signal to the
bus 190 corresponding to the decoded audio and/or visual programs.
It is to be understood and appreciated that multiple tuners 200 may
be incorporated into the box 100 so as to enable the system to
receive, decode, and play or record multiple broadcast and/or
stored programs concurrently. Moreover, multiple tuners may be
employed to receive broadcast programs from different sources of
programming (e.g., cable and satellite).
[0080] Also coupled to the bus 190 are an audio digital-to-analog
("D/A") converter 210, which provides audio output to the
television set 110, and a video encoder 220, which provides video
output to the television 110. The outputs of the audio converter
210 and the video encoder 220 are combined by conventional
circuitry (not shown) to provide the link 130 to the television
110. While the audio converter 210 and video encoder 220 have been
described as providing analog output signals, it is to be
appreciated that corresponding digital components may be employed
provided that the television or other associated display and/or
audio equipment are capable of demodulating such signals.
[0081] An IR interface 230 also is coupled to the bus 190 for
detecting IR signals transmitted by remote control 120. In response
to the IR signals, the IR interface 230 provides corresponding
digital signals to the bus 190 indicative of the IR signals 170.
The signals from the IR interface 230 are utilized, for example, to
control a GUI displayed on the television 110 (or other display)
and/or execute command instructions associated with the IR signals
170. As a result, a user may employ the remote control 120 to send
and/or receive email, connect to and navigate the Web, select audio
and/or visual programs, program recording of selected programs,
etc.
[0082] A digital video recorder ("DVR") 240 also is coupled to the
bus 190 for recording selected audio and/or visual programs in
response to instructions from the processor 180. The DVR 240 stores
recorded programming on an associated storage device 242 (e.g.,
magnetic, optical, magneto-optical, or other equivalent mass
storage medium) and may employ appropriate data compression
techniques, such as the Motion Picture Experts Group ("MPEG")
family of compression/decompression standards (e.g., MPEG-2),
although other data storage formats (analog or digital) also may be
utilized. A user may, for example, employ the remote control device
to retrieve selected programming for playing or sending a selection
to an associated peripheral device, such as the television 110. For
example, the DVR 240 may maintain in associated memory 242 a data
structure, such as a table, indicative of audio and/or visual
programs that are to be recorded. Another table may be provided for
storing a listing of recorded programs stored in the storage device
242. A user may, for example, employ the remote control 120 to
graphically navigate the programming lists, modify or update a
programming list, or select to view a recorded program of interest.
As set forth in greater detail below, an email message also may
contain program criteria based on which the processor 180 may
instruct the DVR 240 to add program criteria to the program list
for recording corresponding broadcast programming.
[0083] A communications device 250 is coupled to the bus 190 to
provide bi-directional data communication through the connection
160. The communications device 250 may, for example, communicates
with the server 20 and/or the other server(s) 50 (FIG. 1B) through
the connection 160. The communication device 250 may be a
conventional telephone modem, DSL modem, an ISDN adapter, or any
other suitable data communication device. A read-only memory (ROM)
260 and a random access memory (RAM) 270 are also coupled to the
bus 190. The RAM 270 provides the main memory into which the
operating system and application programs are loaded for
controlling operation of the set-top box 100 and associated
peripheral equipment. The ROM 260 may include programmable-erasable
memory, such as an electrically-erasable programmable ROM
("EEPROM") or flash memory.
[0084] Other devices also may be coupled to the bus 190, including
an expansion bus (not shown). By way of example, the expansion bus
is a high-speed, multiplexed (address and data), parallel data bus
that is used to connect various peripheral devices to the set-top
box 100. Peripheral devices which may be connected to the box 100
using the expansion bus include devices such as, for example,
printers, mass storage devices (e.g., CD-ROM, digital versatile
disk ("DVD"), magnetic disk, etc.), microphones, video cameras,
video tuners, and additional data communication devices. A client
PC also may be directly coupled to the client bus 190 through the
expansion bus. It will be recognized that various adapters may be
used to interface the expansion bus with bus 190 the details of
which are not required for an understanding of the present
invention. Additionally, while the DVR 240 is illustrated as being
an integrated part of the box 100, it is to be understood that the
DVR alternatively may be external to the box, such as coupled to
the bus 190 through the expansion bus.
[0085] FIG. 3 illustrates a functional representation of the DVR
240 operating as part of the client system 40a in accordance with
an aspect of the present invention. As mentioned above, the DVR 240
includes a mass storage device 242, such as a hard disk drive or
other suitable non-volatile data storage device. The storage device
242 includes, among other things, a program list 280 that is
indicative of audio and/or visual program content that is to be
recorded.
[0086] The storage device also includes a program database 282 for
storing recorded programs, such as in a compressed data format. As
described herein, each program may be formed of a plurality of
discrete program segments that are linked together and stored in
the program database 282 so that the individual program segments
may be combined in a predetermined order, such as may be indicated
in the token(s) representing the program segments. The storage
device 242 further may include a separate commercial database 284
for storing program segments corresponding to advertisements. It is
to be appreciated that, for purposes of practicing the present
invention, program segments for shows and advertisements may be
employed in a substantially identical manner. As a result, program
segments may be selectively combined at the client system in an
order, such as may be indicated in a token representing a
particular program or as may be programmed by a service provider.
By way of example, the client system may be programmed to select
commercials from its stored database based on viewing
characteristics of the client system, such as, for example, who is
watching, the time of day, the particular show being viewed, the
type of show, etc. In this way, program segments from the
commercial database 284 may be dynamically inserted between
adjacent pairs of program segments of a corresponding program from
the program database 282 to provide customized advertisements
during playback of the corresponding program.
[0087] The DVR 240 also includes a decoder/encoder 290, such as
according to an MPEG standard format (e.g., MPEG-2) for
coding/decoding audio and/or visual data (movies, video, music,
etc.) in a digital format. It is to be understood and appreciated
that other encoding/decoding schemes may be utilized, and that all
such schemes are within the scope of the present invention.
[0088] By way of example, the DVR 240 also is programmed (e.g.,
computer-executable code stored in the storage device 242) to
include a token application or API 300 that may run at the client
system. The token application 300 enables interactions with tokens,
in accordance with an aspect of the present invention, so as to
facilitate remote programming of the DVR 240 based on program data
contained within a received token. The token application 300, which
runs in the processor 180 and associated memory, may be used in
conjunction with an email application 310 and/or an EPG 320 also
running in the processor 180 of the client system, such as to send
and/or receive an email message having one or more associated
tokens indicative of preselected audio and/or visual programs.
[0089] As used herein, the term "token" refers to transportable
data or information that identifies a specific audio and/or visual
program or a segment of a specific audio and/or visual program. The
token may include an XML formatted packet of data having an agreed
upon format (or schema--see FIG. 8) for identifying pertinent
program information for a corresponding segment of broadcast audio
and/or visual information so as to enable the DVR 240 to add
program criteria to the program list 280 for recording the program.
A token may include specific tokens requested by the user and/or
those provided to the user as part of a subscription.
[0090] A token, for example, may be communicated to and from a
client system as an attachment to an email message (see, e.g., FIG.
5), as well as by other data communication methods. Other methods
for sending tokens to a client system may include other Internet
Protocol from a remote server, TCP/IP or other protocol on a local
network (e.g., a home network), etc. A client system further may be
programmed to call a certain telephone number (e.g., corresponding
to a service provider) to connect to the service provider's
computer that provides one or more tokens, which previously may
have been assigned to the client system, to remotely program a
recording device associated with the client system to record each
program represented by a token. A token also could be sent to a
user as part of a digitally encoded message (or data packet)
embedded within a globally broadcast signal (cable, satellite,
etc.) that is received at a client system, such as a separate
channel or on a subcarrier of a broadcast channel.
[0091] Those skilled in the art will appreciate other methods or
processes that may be implemented (e.g., as part of the token
application 300) at a client system for receiving tokens, in
accordance with an aspect of the present invention, based on which
a recording device, such as the DVR 240, may be programmed to
record a specific program represented by each token. It further
will be appreciated that, in accordance with an aspect of the
present invention, a given client system may be programmed and/or
configured to employ more than one type of data communication
protocol for sending and/or receiving such tokens.
[0092] Referring back to the example of FIG. 3, the token
application 300 includes a token decoder 330 and a token encoder
340 for respectively decoding and encoding token information.
Specifically, the token decoder 330 extracts token information from
a token. For example, a user may select a token with a user input
device (e.g., the remote control 120 of FIG. 2), from which DVR
programming may be implemented.
[0093] When a client system receives a token having program data,
such as may be associated with an email message, for example, the
token application 300 may employ a token authorization/translation
module 350. It is to be appreciated that the client system may
receive the token by other data communication mechanisms (wired or
wireless). The token authorization/translation module 350
determines whether the token originated from an authorized source,
such as a trusted friend, a website, or other pre-authorized
location (e.g., a service provider). When the token is sent
associated with an email message, for example, the token
authorization/translation module 350 may determine whether the
message is from an authorized sender based on the sender's email
address and/or an authorization password provided with the email,
such as part of the token or another email attachment. If a proper
authorization mechanism is provided, the token authorization module
may accept the token. Once accepted, a token is utilized to program
the DVR 240 for recording the selected audio and/or visual
program(s) when broadcast.
[0094] In contrast, if no authorization mechanism is provided to
permit automatic acceptance, the user may be prompted with a
graphical display requesting explicit instructions as to whether
the token should be accepted. In order to mitigate the potential of
receiving false authorizations via email (or spamming), password
protection or other authentication techniques may be employed. The
password may be provided (e.g., entered by the sender) as part of
the token or it may be in another portion of the email message.
Alternatively or additionally, the sender's email address may be
examined to determine whether it corresponds to a source that has
been pre-authorized by the user.
[0095] The token authentication/translation module 350 also may be
employed to translate each token into a predetermined format for
selectively programming a PVR to record the program(s) represented
by the token. The token authentication/translation module 350, for
example, may be resident within the client system (e.g., part of
the token application 300 (as shown)) and periodically updated to
include program criteria for a plurality of programs in the local
tuning space associated with the client system. Alternatively, a
translation module (or a portion thereof) may be a remote
component, such as resident on a server (e.g., the server 20 shown
in FIG. 1B). The token authentication/translation module 350 may be
implemented, for example, in response to receiving an email message
at the client system after the token associated with the message
has been authenticated. Alternatively, a remote translation module
may be initiated at a server when the token is obtained from the
server and/or forwarded to a PVR. Regardless of its implementation,
the program criteria provided by the token enables the PVR to be
programmed to record selected programs broadcast locally relative
to the client system. The discrete nature of having a token
associated with a specific program enables other client systems to
selectively determine which token (any, all or none) to execute
specific instructions to record a specific program.
[0096] The token encoder 340 is operative to encode program data in
the form of a token, such as may be associated with (e.g., attached
to) an outgoing email message based one or more selections of the
user. In particular, the token encoder 340 operates to place
programming data associated with a selected audio and/or visual
program into a predetermined format for a token decoder, such as
may be resident at another client system or remote device. For
example, a user may select audio and/or visual broadcast
programming of interest and send an email message to one or more
other persons. The token encoder 340 creates a token corresponding
to the programming selected by the user. The token is then attached
to an email message, such as with the remote control 120 (FIG. 2).
It is to be appreciated that each token may include program
information associated with a single program or, alternatively, a
token may bundle program information, which is then decoded into
individual programming selections by an appropriate token
decoder.
[0097] The token application 300 also includes a token graphics
module 360 that controls the graphical display associated with
creating, sending, receiving, and viewing programming information
associated with a token. The token graphics module 360 writes a
graphical user interface (GUI) to a window address to display
selected information to the user. The user interacts with the
displayed GUI by employing a user input device, such as the remote
control 120 (FIG. 2).
[0098] It is to be appreciated that a token application (or
portions thereof), in accordance with the present invention, also
may be resident in another device, such as the remote computer 30
(FIG. 1B), for attaching tokens to email messages corresponding to
audio and/or visual programs selected by the user of such device.
In this way, a user may employ the other device to locate and
select audio and/or visual programs and to send an email message to
one or more selected email addresses having an attached token (or
tokens) indicative of the selected programming. For example, a
PC-based EPG may be utilized to browse the data-intensive Internet
and locate programming content. The token application (including a
token encoder thereof), which is associated with the EPG, places
the programming information into a predetermined format as token
associated with an email message.
[0099] FIG. 4 illustrates a remote computer system 30, which may
form part of the system 10 of FIG. 1B, in accordance with an aspect
of the present invention. It is to be understood and appreciated
that the illustrated computer system 30 is one possible example of
architecture; a computer is not restricted to such architecture for
purposes of practicing the present invention. The computer system
30 includes a processor 370 and memory 372 operatively coupled to a
system bus 374. The bus 374 may represent multiple physical buses
connected by various bridges and/or adapters, the details of which
are not required for an understanding of the present invention. The
memory 372 includes ROM 376, RAM 378, and a mass storage facility
380, each of which may be coupled to the bus 374 via a suitable
interface (not shown). The ROM 376 may include programmable and/or
programmable-erasable storage. The mass storage facility 380 may
include a magnetic, optical, magneto-optical, or other equivalent
mass storage medium.
[0100] The computer system 30 also includes a communications device
382 and various input/output (I/O) devices 384 and 386, which also
may communicate over the bus 374. The I/O devices 384 and 386, for
example, may include interfaces that connect to external peripheral
devices, such as a user input device (e.g., mouse, keyboard, etc.)
388 and a display device 390, respectively. It is to be understood
and appreciated that additional I/O facilities (not shown) also
could connect to other peripheral devices or other related
computing devices.
[0101] The communication device 382 may be a conventional telephone
(POTS) modem, a DSL modem, a cable modem, an ISDN adapter, or any
other suitable data communication device (wired or wireless). The
communication device 382 may be used to communicate data between
the computer 30 and another computer (e.g., a remote server or
another PC), such as to receive and send email, browse the Web, and
implement other queries related to audio and/or visual
programs.
[0102] While, for purpose of brevity, the computer 30 is
illustrated as a single device, it is to be appreciated that it may
actually comprise multiple devices connected in a distributed
architecture. In distributed system, the communication device 382
(or one of the I/O facilities 384-386) may be used to communicate
data between the computer 30 and other physical devices used to
implement selected functionality remotely.
[0103] By way of example, the computer system 30 is a personal
computer (PC), although it also may be a workstation, a hand-held
computing device, a wireless web phone, a microprocessor-based or
programmable consumer electronic system (wired or wireless), or
similar type of device. A PC, generally speaking, is able to
navigate the intensive Web content by employing an input device,
such as a mouse or other input device. The user input device 388
and PC, facilitate navigation of a variety of resources available
on the Web along with displaying high resolution textual
information that, in turn, may enhance the program selection
process. The remote computer 30 further may be employed to send to
one or more client systems (or directly to a recording device) an
email message having a token(s) indicative of program criteria
selected by the user of the remote PC. The use of specific tokens
for each program enables other clients receiving the emails with
tokens to selectively determine which of the programs it will
record.
[0104] The computer system 30 may, in accordance with an aspect of
the present invention, be programmed and/or configured to implement
a variety of processes or methods with respect to the applications
and/or other data stored in the memory 14. It will be recognized
that processes described herein as being performed by the computer
30 may result from the processor 12 executing software
instructions, from operation of hardwired circuitry, or combination
of both. It will be appreciated that in a distributed computing
model, for example, part of one or more of the applications,
method, or functions also might run on a computer remote relative
to the computer 30. The processes also may run on a server computer
to which the local computer 30 is connected through a network
infrastructure, such as the Internet, with a graphical user
interface being displayed on the local computer. As set forth in
greater detail below, the processes and/or interfaces may include
an EPG 392, subscription(s) 394 from a service provider, a program
selection mechanism 396 for obtaining tokens for selected programs,
and any other functionality 398 that may be useful in searching for
and obtaining information and/or tokens indicative of one or more
audio and/or visual programs.
[0105] Briefly stated, the EPG 392 may be implemented in connection
with one or more databases, such as at one or more remote computers
(servers). A user at the local computer may employ the EPG 392 to
filter through information content in the database(s) and help
locate one or more audio and/or visual programs matching selection
criteria entered by the user.
[0106] A subscription process 394, for example, may be provided by
a website running on a server computer that provides an interface
to which a user may connect for sorting through information and
program criteria stored in one or more databases in association
with the subscription. The subscription 394 employs selection
criteria selected by the provider of the subscription service to
provide a set of programs from which a subscriber or user may
select. A user/subscriber, for example, may access a website for a
subscription to receive information about selected programs, access
links to related websites, obtain or send program criteria (e.g.,
tokens) indicative of audio and/or visual programs selected by the
service provider, etc. The subscription function 394, which may
include passive or active lists maintained on one or more servers
accessible via the Internet (e.g., for a trusted television or film
critic, an Internet movie database, American Film Institute,
etc.).
[0107] The program selection process 396 is employed by a user of
the local computer to obtain and/or send a token representing a
selected program to a recipient, which may be the user, the user's
PVR, or another recipient. The user also may select to store tokens
remotely, such as at a server, from which a client system may
connect to (directly or indirectly via a network infrastructure) to
obtain one or more of the stored tokens for programming the user's
PVR. The recipient of the token may be the user or one or more
other users or a recording system. The program selection process
396 may be part of a website running on a server computer and/or
may run on software resident in the local computer 30.
[0108] The computer 30 also may utilize other websites and/or
functionality 398, such as to provide additional functionality with
respect to searching for programs and for obtaining and/or sending
tokens related to selected programs. For example, a website may
exist that enables a user to create a customized filter (similar to
a subscription) based on selection criteria provided by the user.
The other functionality 398 may have several programmable levels,
similar to the levels of criteria that may be selected with the EPG
function 36. The other functionality 398 further may work in
conjunction with Internet browsing software and search engines
(local and remote) programmed in the remote computer for searching
various websites for programs matching the selection criteria
programmed in the filter function. The results are provided to the
computer 30 as part of an interactive display from which a user may
select one or more programs, obtain additional information about
programs, and obtain and/or send tokens related to each selected
program(s).
[0109] It is to be understood and appreciated that the
functionality described with respect to the remote computer 30 also
may be implemented at the client systems 40 (FIG. 1B). For example,
the functionality may be provided at a client system 40 in
connection with a television-based Internet service.
[0110] FIG. 5 illustrates a graphical representation of an email
GUI 400 having a text message 402 and three tokens 404, 406, and
408. In this example, the tokens 404-408 are illustrated as
attachments to the email text. It is to be understood and
appreciated, however, that a token also may, in accordance with an
aspect of the present invention, be associated with an email
message in other contexts. For example, a token may be inserted
into the text of an email message in the form of a Component Object
Model (COM) object or by employing any other embedding or linking
technology to associate the token with an email message (e.g.,
CORBA, etc.). Moreover, a token having audio and/or visual program
data may be communicated from a remote computer to a client system
via other data communication means.
[0111] Each token 404, 406, 408 has an associated filename having a
suffix ".TOK" so as to identify each respective token as a token to
an appropriate application (or other object). In particular, the
token filenames are "TITLE1.TOK", "TITLE2.TOK", AND "TITLE3.TOK",
with each filename identifying either a title of a corresponding
program or describing the program in a predetermined manner.
Associated with each token also may be an indication as to the
length of the program and/or its rating. The rating system, for
example, may be an established standard. In order to obtain
additional information about programming corresponding to a
particular token 404, 406, or 408, a user invokes one or more
selected tokens, such as by selecting the token with a user input
device (e.g., the remote control, a mouse, etc.).
[0112] The email message 402 also may include a uniform resource
locator ("URL") 410 that identifies a Web site selected by the
sender. For example, the sender may direct the email recipient,
Steve, to a Web site containing an interesting arrangement of
programming selections from which corresponding tokens, in
accordance with the present invention, may be derived.
[0113] FIG. 6 illustrates a graphical representation of an
exemplary pop-up window 412 (or GUI) that might be displayed in
response to invoking the token 406 (cross-hatching is used to
indicate the token being selected). The GUI 412, for example,
provides information indicative of the audio and/or visual program
identified by the token 406. By way of example, different aspects
of the program information may be separated in individual folders,
such as a DESCRIPTION folder 414, a TIMES & CHANNEL folder 416,
and a DETAILS folder 418. The DESCRIPTION folder 414 may contain a
short summary of the program and an image (or a short preview
video) 420 for the selected program. The attachment also identifies
the airdate for the program.
[0114] Action buttons, namely, a SEND button 422 and a RECORD
button 424 also are associated with the pop-up window 412. The SEND
button 422 enables the user to send the token to an email address,
such as may be located on a distribution list of the email GUI 400.
The RECORD button 424 provides a mechanism to enable the user to
program an associated device (e.g., a PVR) to record the audio
and/or visual broadcast programming identified by the token
406.
[0115] By way of example, when the email reader 400 is part of a
client system, such as a client system, the RECORD button 424 may
be selected to cause program information from the token 406 to be
added to a program list of the associated PVR. As a result, the PVR
will record the program on its corresponding airdate and time based
on the token. Alternatively, when the email reader 400 is part of a
remote computer, the RECORD button 424 may cause the token to be
sent as part of an email message to an email address of the user's
(or another person's) PVR. As mentioned above, a PVR may be
programmed to automatically program operation of the PVR in
response to receiving an email message having a token from a
pre-authorized source. The authorization or authentication, for
example, may be determined based on the email address of the
sender, a password provided with the email (e.g., as part of the
token or another attachment), or another authentication
technique.
[0116] If the user desires neither to record the program nor to
send the token to another email address, the user may simply close
the pop-up window 412. The user may then elect to view the other
attachments 404 and/or 408, close the email, or take other action
relative to the email message 402 or its attachments (e.g., delete,
forward, reply, go to the URL 410, etc.).
[0117] FIG. 7 is a graphical representation of an exemplary GUI
430, which might be displayed in order to obtain programming
authorization in response to receiving tokens. In this example, the
GUI 430 includes a message 432 indicating that three tokens have
been received from "curtis@msn.com." The GUI 430 provides the user
with options concerning whether to accept the tokens. The options
are in the form of action buttons, which may include: a YES button
434; a NO button 436; an ALWAYS ACCEPT button 438 (upon
authentication); and a NEVER ACCEPT button 440.
[0118] For example, if the user selects the YES button 434, a token
application adds the tokens to a program list of the PVR to record
each of the shows indicated by the accepted tokens. The NO button
436 is employed to decline the tokens. Selecting the ALWAYS ACCEPT
button 438 results in a token application adding the sender's email
address to list of pre-authorized sources, which may result in
automatic programming of the user's PVR according to tokens
received from that source. In contrast, the NEVER ACCEPT button 440
may add the sender's email address to another list or filter, which
identifies sender's whose email is to not to trigger a programming
authorization request 430.
[0119] FIGS. 8-10 are examples of graphical interactive graphical
user interfaces, such as may be implemented in connection with one
or more websites to help locate programs based on program selection
criteria, which may be provided by a user and/or a service
provider. The websites, for example, may be accessed from a remote
computer or from a client system. A user also may employ the
processes and/or interfaces of associated websites to manipulate
and/or view a token and its associated information in accordance
with an aspect of the present invention. It is to be appreciated
that the illustrated graphical representations are for purposes of
simplicity of explanation and that any configuration of display and
graphical user interface may be implemented in practicing the
present invention.
[0120] FIG. 8 illustrates an example of a token schema 450 that may
be utilized in accordance with an aspect of the present invention.
The token schema 450 may be a multi-level data structure that
contains a plurality of fields for holding different types of data.
Each field also may contain actual data, such as in the form of raw
data, an object, a component, a module, etc., or a link to the data
associated with the link. By way of example, the schema 450
includes a header 452 that identifies a group of data as a token as
well as may define attributes of the token schema and/or the
different levels of data.
[0121] The token schema 450 may include a globally unique
identifier for a token (a "token GUID") 454, which uniquely
identifies a respective token obtained from a server 20 (FIG. 1B).
A service provider, for example, may employ the token GUID 454, to
track a token as it is transmitted from one computer to another as
well as to provide a link between a specific token and billing
information, such as in situations when a token corresponds to a
program that has been purchased or rented from a service
provider.
[0122] The token schema 450 also includes program criteria 456 for
identifying different characteristics of the audio and/or visual
program represented by a token. One aspect of the program criteria
456 may be a global unique identifier (GUID) 458 identifying a
specific program (hereinafter referred to as a "program GUID"). The
program GUID 458, for example, may be a unique program
identification number (or series of numbers and other characters)
that represents a specific program, such as may be established by a
service provider. A program GUID 458 may further include other data
that may be employed to uniquely identify a program, either
globally or in a local tuning space. The program GUID individually
may identify a program with sufficient particularity so that a
recording system may be programmed to record the program
represented by the token.
[0123] The program criteria 456 further may include one or more
other program characteristics 460 that may be employed to help
identify a program. As illustrated in the example of FIG. 8, the
program characteristics 460 may include data identifying different
aspects of a program, such as, for example: title, keywords,
rating, director, producer(s), actors and/or actresses, host(s),
format, category, channel or broadcast network, genre, broadcast
date, broadcast time (if known), program duration, a URL link to
information (e.g., other program characteristics, a program GUID,
local tuning space information, etc.) about the program, and/or any
other aspect of a program that could be used to help identify a
particular program. It is to be appreciated that each type of
program characteristic may not be applicable to all types of
programs. Accordingly, a token might not include each type of data
element and may further include other agreed upon
characteristics.
[0124] The token schema 450 further may include program description
462 to provide additional information about a program represented
by the token. The description field 462, for example, provides a
brief description about the program, such as including its topic or
plot, its length, a rating, etc. The description 462 also may form
part of the program criteria that may be employed to identify the
program. That is, the text of the description 462 may be searched
at a server to locate a program based on selection criteria entered
by a user. A user may read the text portion of the description 462
so as to make a more informed decision whether to record the
corresponding program, such as by invoking (or opening) a
corresponding token at a computer displaying the token (see, e.g.,
FIGS. 5 and 6).
[0125] The token schema 450 also includes a program image/video
element 464 (e.g., provided in JPEG or MPEG formats) to provide
additional information about the program represented by the token.
The program image/video element 464 of the schema 450 provides an
image and/or an audio/visual clip from the program (e.g., a
trailer). For example, a short preview and/or sound effects or a
link to such may be provided as part of the token. Biographies of
the stars or hosts also may be provided as part of the image
element 464 and/or the description element 462. A user may view the
image/video associated with a token by invoking the token at the
user's computer (see, e.g., FIGS. 5 and 6).
[0126] The illustrated example of a token schema 450 also supports
a token authentication element 466. The token authentication
element 466, for example, may include a password or other
authentication data that a PVR may employ to verify that a token is
from a trusted source. When appropriate authentication data is
included as part of a token, a PVR may automatically accept the
token and program the PVR to record the program represented by the
token, such as based on the program criteria 460. By way of
example, a user may receive an email message at a remote computer
having an associated token. If the user desires to record the
program represented by the token, the user may forward the token to
an email address associated with the user's PVR. When the token is
received at the PVR and upon authentication of the message (e.g.,
based on a user's email address, authentication data, or other
authentication techniques), a token programming component running
in the PVR may add the program to the program list of the PVR.
[0127] The token schema 450 also may include a token encryption
element 466, which may include data or other proprietary
information for controlling or monitoring operation of a PVR in
connection with a token and/or a program represented by the token.
By way of example, the encryption element may contain data that
enables a PVR to record and/or playback a pay program. The data may
contain part of a decryption algorithm for decoding an encrypted
broadcast, such as at playback or during recording. The data within
the encryption element 468 also may be employed to restrict access
to a recorded program to particular times of the day, to limit the
number of times that a recorded program may be played, and/or to
perform any other monitoring and control functions associated with
a particular program. The data within the encryption element 468
may be linked to other data such as the token GUID or a PVR GUID,
which may uniquely identify a PVR.
[0128] The token schema 450 also may include other elements 470.
The other elements 470 may be employed to perform other functions
related to the recording or playback of a program and/or related to
the sending of a token for a particular program. For example,
account information, such as billing, account status, etc. may be
implemented within the other element 470. Those skilled in the art
will appreciated that part of the other element 470 also may be
reserved for future use, such as to accommodate new features.
[0129] The token schema 450 may be arranged in an agreed upon
format, such as an XML (extensible mark up language) formatted
block of data. An example of a schema for a token is illustrated in
Table I. It is to be appreciated that, as illustrated in the
example of Table I, a token might not include data for each type of
element in the token schema 450.

[0130] FIG. 9 illustrates a graphical representation of an EPG
interface 500 that may be displayed on the remote computer 30 or a
client system 40 (FIG. 1B), although the corresponding process may
run on the remote computer or as part of a website running on a
server 20, 50 to which remote computer is connected (FIG. 1B). The
EPG interface 500 provides an interactive EPG 502 that enables a
user to select one or more selection criteria to search for
programs in which the user may be interested. By way of example,
the EPG 502 may include a keyword search tool 504 for receiving one
or more keywords (e.g., as part of an Active Server Page ("ASP")
request) identifying program characteristics about which a user
desires to locate one or more programs. The EPG 502 further may
include a plurality of other search tools having a plurality of
selectable parameters that may be employed to search for programs
meeting selected parameters. In the illustrated example, the
additional search tools include a format list 506, a category list
508, a time list 510, a rating selection mechanism 512, and a
channel selection list 514. Each list 506-514 may include one or
more selectable parameters (or selection criteria) that a user may
employ to narrow the search for a program or a type of program.
[0131] Search results matching (or substantially matching) the
selection criteria are returned to the remote computer and
displayed on an associated graphical user interface 520, such as
displayed adjacent to the EPG 502 (as shown). It is to be
appreciated that the EPG 502 and adjacent interface 520 also could
be implemented in association with separate webpages provided to
the user. The interactive display provides additional functionality
to enable a user to sort through the search results, such as
according to one or more characteristics of the programs. For
example, action buttons 522-530 may be provided so that a user may
organize the search results in a desired format, such as
alphabetically, by format, by channel, by time, or by rating,
respectively.
[0132] Each program in the displayed search results, for example,
may include its title (e.g., TITLE 1-TITLE 6) and/or other
pertinent information (e.g., ratings, duration, etc.). Additional
information also may be associated with each program that a user
may access by selecting a corresponding arrow 532 with a user input
device (e.g., a mouse). By selecting an arrow 532 of a
corresponding program (TITLE 6), for example, one or more pop-up
windows 534-538 may be displayed. The pop-up windows may include a
window 534 for providing a brief description of the program, a
window 536 listing the times and channels when the program is to be
broadcast, and a window 538 indicating other related program
details.
[0133] A selection box 540 also is associated with each program,
which a user may select and deselect in order to add and remove
programs from an associated storage bin. A storage bin, for
example, provides a link between each program selected by a user so
that program criteria associated with each program (e.g., a token
and other related program information) may be sent to one or more
recipients. As mentioned above, a token is a formatted program
identifier that identifies a program with sufficient detail so that
a recording system may employ the token to record the program
represented by the token. In certain circumstances, it further may
be necessary to translate a token to obtain program information for
a particular local tuning space before a recording system is able
to record the corresponding program. As described herein, the
translation may occur locally at the recording system and/or at a
server. Additional information, such as the information contained
in the pop-up windows 534-538, also may be operatively associated
with each token.
[0134] The program criteria may be sent to a recipient (the user,
another individual, a PVR, etc.), such as in response to a user
selecting a SEND button 542 or RECORD button 544 displayed on the
interface 520. Each of the SEND button 542 and the RECORD button
544 associates or attaches a token for each program that has been
selected from returned search results on the interface 520. The
SEND button 542, for example, enables a user to send a token(s) for
each selected program to an email address (or addresses), such as
may be selected by the user from an email distribution list. The
RECORD button 544 provides a mechanism to enable the user to
program an associated device (e.g., a PVR) to record the audio
and/or visual broadcast program identified by each selected
token.
[0135] Each button 542 and 544 may be associated with an email
application or process implemented at a server 20 or 50.
Alternatively, the email process alternatively could be implemented
locally at the remote computer 30 or the client system 40 (FIG.
1B), such as after the token(s) for each selected program has been
downloaded. By way of example, the user may employ the SEND button
542 to send a token(s) for each selected program to one or more
email addresses provided. The RECORD button 544 may be selected to
cause a token(s) for each selected program to be sent as an email
attachment to one or more predetermined email addresses, such as
may be associated with the user's (or another person's) PVR. It is
to be appreciated that tokens may be provided to the PVR using data
transfer mechanisms other than email. The PVR may, in turn, employ
each token to add program information based on the token to a
program list of the associated PVR (which program information may
be based on an appropriate translation of the token). As a result,
the PVR will record each program on its corresponding airdate and
time.
[0136] FIG. 10 is an example of a homepage 550 for a website (e.g.,
somewebsite.com) that may be employed to provide an interactive
graphical user interface to facilitate program selection by a user.
The website 550 may be associated with one or more databases that
may run on one or more computers, such as the servers 20 and 50
(FIG. 1B).
[0137] It is to be appreciated that, in accordance with an aspect
of the present invention, one or more servers 20 or 50 may operate
as a central clearing house for storing the information necessary
for recording audio and/or visual programs. Accordingly, one or
more webpage service providers may, in turn, subscribe to and
utilize the central clearing house for providing their own users
with programming data (e.g., tokens) for programs selected by the
user. Appropriate programming data for a user's local tuning space
may be obtained for selected programs based on identifying data
(e.g., zip code, broadcast service provider(s), etc.) provided by
the user.
[0138] As discussed above, the identifying data, for example, may
be provided when a user logs into a service, such as a website. The
identifying data also may accompany a user as the user navigates
the Web, such as may be incorporated into a suitable identification
scheme.
[0139] By way of example, the local tuning space and location
information for a PVR may be incorporated into a Microsoft
Passport.TM. service and/or part of a Microsoft Wallet.TM. service,
developed by Microsoft Corporation of Redmond, Wash., or a similar
type of service. The Microsoft Passport.TM. and/or Microsoft
Wallet.TM. services store pertinent user information in association
with a login ID and a password provided by the user. Accordingly,
participating Passport.TM. sites may utilize PVR-related data
associated with the user (e.g., part of their Passport or Wallet
services) to provide a user with local program criteria for each
selected program. The user identification information further may
be utilized by the central clearing house server and/or sites
accessing the central server to collect information, such as
demographic data, about each user and the programs selected to be
recorded by each user.
[0140] Referring back to FIG. 10, the homepage 550 may include a
tool bar or panel 552 having a plurality of selectable buttons
associated with each page thereof. By way of example, a brief
description of each button in the tool bar 552 is contained in
TABLE II. In addition to the functionality provided by the tool bar
552, the website homepage 550 may include a listing of one or more
hot picks 554 and links 556 to related websites (website A and
website B) to which a user may subscribe.

[0141] The homepage 550 further may include a user-configured
section 558 for displaying pertinent account information to a user
who is logged in to the website. The user-configured section 558,
for example, may include one or more drop down menus 560 for
different program subjects, such as new releases and a listing by
genre. A keyword searching mechanism 562 also may be located within
the user-configured section 558, along with links 564 to additional
searching tools. The homepage 550 further may include a listing (or
section) 566 for displaying new programs.
[0142] Each of the hot picks section 554 and the new selections
section 566 includes one or more selectable boxes 568 associated
with an identified program. The selectable box 568 may be selected
to add a corresponding program to a "MY BIN" storage area
associated with the website. When a user selects a MY BIN button
570 of the toolbar 552, for example, the user is provided an
interactive graphical display, such as shown in FIG. 11.
[0143] FIG. 10A illustrates a graphical representation of a
subscriptions webpage 574, which may be accessed in response to a
user selecting the subscriptions button 576 from the toolbar 552
(FIG. 10). For sake of brevity, identical reference numbers refer
to identical components previously described in FIG. 10. The
subscriptions webpage 576 contains a list of all subscriptions 578
to which a user belongs. The subscriptions 578, for example, may be
links (URLs) to other websites or different pages within the
website of FIG. 10 for providing program related information.
[0144] One subscription ("subscription 6") 580, for example, may
provide a link (URL) to a website for a trusted film critic, which
may provided within the graphical interface of the website so that
the tool bar 552 is displayed. An example of a graphical
representation for a subscription website 582 for the Trusted Film
Critic is illustrated in FIG. 10B, in which identical reference
numbers refer to parts previously identified with respect to FIG.
10A. The subscription website 582 may include links to program
selections and program-related information selected by the Trusted
Film Critic, which may be a person(s) or an organization. By way of
example, the website 582 may include selectable buttons or
hypertext links 584 to display: an interactive of list of new
programs selected by the critic (WHAT'S NEW); the critic's favorite
movie of the month (PICK OF THE MONTH); special programs that are
dear to the critic (SPECIAL PICKS); a list of the critic's all time
favorite programs (MY FAVORITES); children's programs selected by
the critic (FOR THE KIDS); the critic's top 100 rated movies (TOP
100); and a historical list of selected programs (FROM THE
ARCHIVE).
[0145] An interactive graphical program list 586 of the programs
associated with a particular one of the links is displayed on the
webpage adjacent to the links. The graphical list 586, for example,
may include an image (or audio/visual clip) and brief description
associated with each program in the displayed list 586. Each
displayed film in the graphical program list 586 also has an
associated selectable box 588, which may be selected (and
deselected) to add (and remove) the associated program to (and
from) the programs contained in the MY BIN 570. The MY BIN button
570 also may include a graphical (and/or audible) indicator 590 to
indicate the number of selected programs that are in a user's
storage bin.
[0146] FIG. 10C illustrates a graphical representation of a WHAT'S
HOT webpage 592, in which identical reference numbers refer to
corresponding components previously identified with respect to FIG.
10B. The WHAT'S HOT webpage 592 may be accessed in response to a
user selecting the FIND IT, WHAT'S HOT button 594 from the toolbar
552 (e.g., FIG. 10), The WHAT'S HOT webpage 592, for example,
identifies the most recorded programs arranged by program
categories, which may include may include series, movies, sports,
news, and an others category. Each category may include a
corresponding list of programs 596, 598, 600, 602, 604, with the
programs in each list being arranged in order of popularity. The
popularity, for example, may be based on the number users
requesting tokens or the number of users recording a particular
program. The number of users recording a program may be determined
by a server computer, such as by compiling each token translation
request or in response to program information obtained from each
recording system.
[0147] Each program listed has an associated selectable box 606,
which may be selected (and deselected) by a user to add (and
remove) the corresponding program to (and from) the programs
contained in the MY BIN 570. Accordingly, the WHAT'S HOT webpage
592 provides a useful tool that enables a user to select the most
popular programs. The user may then send and/or receive tokens
(together with other related information) for each selected
program. For example, the user may select the user's MY BIN button
570 and then send a message having a token(s) for each selected
program to an email address of a recipient(s), such as disclosed
with respect to FIG. 11.
[0148] FIG. 11 illustrates an example of a webpage 610 for a user's
storage bin in which identical reference numbers refer to
corresponding components previously identified with respect to FIG.
10C. The storage bin webpage 610 may be accessed, for example, in
response to a user selecting a storage button 611 or by selecting
the MY BIN button 570. The webpage 610 includes a selectable list
612 for each program that has been selected by the user, which may
include the title and other program related information. The
webpage 610 also may include a list of show times 614 and other
information 616 (an image, video, description, etc.) for each
program (TITLE 1) that has been selected from the list 612. For
example, one or more program listings 618 and 620 may be provided
within the show times list 614 for the selected program (TITLE 1).
Each program listing 618, 620 may identify the time, date and
channel that the selected program (TITLE 1) is to broadcast within
a given window of time. Each listing 618, 620 also may have an
associated action button 622, 624, which a user may employ to
record the corresponding program. In the illustrated example, the
button 622 corresponds to a pay version of the program and the
action button 624 corresponds to a "free" version ("free" meaning
there is no additional charge provided that the user receives the
associated channel). The pay version, for example, may have an
earlier broadcast date and time than the "free" version.
[0149] The storage bin webpage 610 also may include a SEND button
626, a PURCHASE button 628, and a RENT button 630. Each button may
be selected by a user (with an appropriate user input device) to
initiate the function associated with each button. By way of
example, the SEND button 626 may be employed to send a recipient a
token(s) for each program selected by a user. The recipient may be
identified by the user (e.g., by email address), such as described
above with respect to FIG. 9. Briefly stated, when the SEND button
626 is activated, a function or method associates or attaches to an
email message a token for each selected program. The user may send
the message to one or more individuals, such as to an email address
provided by the user or a predetermined email address stored at the
server.
[0150] The PURCHASE button 628 provides a mechanism to enable the
user to record a pay program in a format that, for example, permits
substantially unlimited viewing of the recorded at an identified
PVR that recorded the program. In contrast, if a user may only
desire to watch a pay program a limited number of times (typically
for a smaller fee), the user may select the RENT button 630. The
RENT button 630, for example, enables a recording system to record
a selected program in a format that only permits limited playback
of the recorded program, such as over a predetermined time period
or for predetermined number of playbacks.
[0151] Similar to the SEND button 626, activation of each of the
PURCHASE button 628 or the RENT button 630 may result in a token
for each selected program being sent to a recipient. The token is
sent, for example, as an attachment to or embedded in an email
message. The message is addressed to the email address of the
recipient, which may be an email address of a PVR or another
address(es) selected by the user and/or a service provider. As
mentioned above, a token may include encryption/decryption data,
such as for a pay program, and/or other authentication data to
permit and control the recording and playback of a corresponding
program.
[0152] While the send, record, and purchase buttons 626, 628, and
630 have been described as triggering mechanisms for sending tokens
to a client system, it is to be appreciated that a client system
may receive tokens by other data communication mechanisms. For
example, activation of the buttons may result in program data
assigned to one or more recipients being stored at a remote
computer (e.g., server 20) for each selected program. A client
system to which the program data is assigned may, in turn, connect
to (directly or indirectly) the server 20 to receive (download)
tokens corresponding to the data for the selected programs.
Alternatively, tokens corresponding to the stored program data may
be periodically sent by the server to each assigned client system,
such as in email messages, by a direct connection (e.g., a modem)
to the client system, or any other data communication
mechanism.
[0153] It is to be appreciated that information and functionality
of the user interfaces associated with FIGS. 9-11 are for purpose
of illustration and that any format and configuration may be
employed by to provide a selectable resource for programs in
accordance with an aspect of the present invention. Moreover, it is
to be appreciated that one or more service providers may provide
websites similar to the illustrated examples. Some or all of such
service providers may utilize a common central clearing house, in
accordance with an aspect of the present invention, that stores the
programming data, although some may employ their own databases.
[0154] FIG. 12 is block diagram of a remote server architecture,
such as the server 20 shown in FIG. 1B. It is to be understood and
appreciated that the illustrated architecture is one possible
architecture; a server 20 is not restricted to such architecture
for purposes of practicing the present invention. The server 20
includes a processor 650 and memory 652 operatively coupled to a
system bus 654. The bus 654 may represent multiple physical buses
connected by various bridges and/or adapters, the details of which
are not required for an understanding of the present invention. The
memory 652 includes ROM 656, RAM 658, and a mass storage facility
660, each of which may be coupled to the bus 654 via a suitable
interface (not shown). The ROM 656 may include programmable and/or
programmable-erasable storage. The mass storage facility 660 may
include a magnetic, optical, magneto-optical, or other equivalent
mass storage medium.
[0155] The server 20 also includes a communication device 662 and
various input/output (I/O) facilities 664, which also may
communicate over the bus 654. The I/O facilities 664 may include an
interface for a monitor, a keyboard, a pointing device, and/or
other similar devices. The communication device 662 may be a
conventional telephone (POTS) modem, an ISDN adapter, or any other
suitable data communication device (wired or wireless). The
communication device 662 may be used to communicate data between
the server 20 and another computer (e.g., the server 50, remote
computer 30, or client system 40 of FIG. 1B), such as to receive
input requests for program information and/or updates for the
information stored in memory 652. It will be recognized that
functions described herein as being performed by the server 20 may
result from the processor 650 of the server executing software
instructions, from operation of hardwired circuitry, or combination
of both.
[0156] While, for purpose of brevity, the server 20 is illustrated
as a single device, it is to be appreciated that it may actually
comprise multiple devices connected in a distributed architecture.
In distributed system, the communication device 662 (or another I/O
facility 664) may be used to communicate data between the server 20
and other physical devices used to implement server functionality.
The server 20 may also include a network interface or other similar
device for communicating with other physical devices that provide
desired server functions. The server system 20 may, in accordance
with an aspect of the present invention, be programmed and/or
configured to implement a variety of selectable processes with
respect to the program criteria stored in the memory 652.
[0157] With reference to FIG. 13, the server memory 652 (e.g., ROM
656, RAM 658 and/or mass storage 660) contains a data structure 666
for storing program criteria representing a plurality of audio
and/or visual programs and other related information. The data
structure 666 may be organized as one or more relational databases,
object-oriented databases, and/or object-relational databases,
although other types of databases also may be implemented at a
server, in accordance with the present invention, to store and
access program data and related information. For example, a
commercially available database engine may be employed in
conjunction with a computer software database program to facilitate
storage and access of program and system related data.
[0158] The data structure 666 may include one or more program
databases 668 that include program information identifying various
aspects of a plurality of audio and/or visual programs. The program
criteria associated with the program database 668 may include the
program GUID (e.g., a unique program identification number) and/or
other descriptive information indicative of program characteristics
for a corresponding program. The other information may include, for
example, title, actors, directors, producer, category, genre,
ratings, keywords, relevant web links, a brief description of the
program, an image or video clip for the program, etc. The program
GUID and/or other related program information for a specific
program may be utilized, in accordance with an aspect of the
present invention, to form a token for the respective program.
[0159] As set forth in greater detail below, the data structure 666
also may include a tuning space database 670, a token database 672,
a stored selection database 674, a ratings database 676, and a user
profile database 678. Those skilled in the art will understand and
appreciate that other databases (alternatively or additionally) may
be used to store and access pertinent information at the server
20.
[0160] By way of example, the processor 650 may run a token
generator 680, which may be an application, function, or method,
for accessing the program database 668 and providing a program GUID
according to selection criteria. The server 20 may receive
selection criteria, for example, based on a query entered remotely
by a user, such as at a client system 40 or remote computer 30
(FIG. 1B). Remotely entered selection criteria may be received at
the server 20 via the communications device 662 or via a user input
device coupled to one of its I/O devices 664. Such selection
criteria may originate, for example, at a remote computer or from
another remote server, such as may be associated with a particular
website. The selection criteria also may be internally stored and
accessed at the server 20, such as may be associated with program
characteristics of a service provider (e.g., the Trusted Film
Critic Website of FIG. 10B). The selection criteria may be stored
as part of a preprogrammed user profile (e.g., stored in the user
profile database 678) or stored in response to selection criteria
that did not yield satisfactory results (e.g., stored in the stored
selection criteria database 674).
[0161] The selection criteria, for example, describes details
concerning an audio and/or visual program about which a user may
desire additional information and/or wish to record. The selection
criteria may indicate any of a variety of characteristics about a
program, such as title, descriptive aspects of the program, actors,
release date, episode, producer, category, genre, rating
information, etc. The server 20 may process the criteria as a query
from a search engine, program criteria from a remote EPG system, or
any other type of request. The selection criteria may be packaged
and sent to the server following a predetermined schema (e.g., as
part of an ASP page request) having agreed upon elements and
attributes for identifying the program characteristics.
Additionally or alternatively, keywords, or natural language
searching capabilities may be employed at the server 20 to search
for program content based on selection criteria.
[0162] The token generator 680 employs the selection criteria to
search the program database 668 and determine whether one or more
audio and/or visual programs contained in the program database (or
other parts of the memory 652) match the criteria. The token
generator 680 returns a token, which may include a unique program
GUID, for each program substantially matching the selection
criteria. By way of example, the token generator 680 may select a
program GUID from the program database 668 for each program exactly
matching the selection criteria. Additionally, the token generator
680 may select program GUIDs for relatively close matches, such as
based on a statistical evaluation of available programs as compared
to the selection criteria. The server 20 may present search results
to the user in the form of a token(s), such as through the
communications device 662 or an input device associated with an I/O
facility 664. The user may, in turn, select one or more tokens, as
desired. Each token further may include or have associated
attributes (or elements), which characterize details concerning the
program, such as in the form of a description of the program,
image(s), audio, etc. Any number of program GUIDs may be obtained
from the server 20 based on the selection criteria.
[0163] When no program(s) matches the selection criteria, the
selection criteria and information identifying the user making the
request may be stored in an associated database, such as the stored
selection database 674. The storing of selection criteria may be
implemented automatically or at the request of the user. The stored
selection database 674 may store pertinent selection criteria in
association with information identifying the user or the computer
of the user (e.g., an email address or other information
identifying the user's PVR) who implemented the request. As a
result, a notification and/or one or more tokens (e.g., containing
a program GUID(s) or other program characteristics) corresponding
to the selection criteria may subsequently be provided to the user,
such as via email or other data communication mechanisms. The
notification or subsequent sending of a token, for example, may be
triggered in response to the program criteria being updated at the
server 20 to include one or more programs better matching the
stored selection criteria.
[0164] The server 20 also may include a translation function 682
for translating or converting a token into program instructions
that identify a specific program as it is broadcast in a particular
local tuning space (or headend). The translation function 682, for
example, interfaces with each of the program database 668 and the
tuning space database 670 to provide localized program information
in a particular tuning space. The translation function 682 provides
a mechanism that enables a recording system to be programmed to
record a specific broadcast program identified by a token or
program GUID for a particular tuning space in which the recording
system is situated for receiving the broadcast. The translation
function 682 may be programmed to, based on a token and/or program
GUID, query the program database 668 and the tuning space database
670. The translation function 682 may also add, extract, and
provide specific tuning information, such as the local time,
frequency or satellite transponder on which a corresponding program
will be broadcast.
[0165] Each tuning space, for example, has a unique channel line-up
for all networks and service providers that broadcast in its tuning
space. A tuning space, for example, may include cable, satellite
(analog or digital), traditional television broadcast (UHF, VHF),
traditional radio broadcast (AM radio, FM radio), HDTV, audio
and/or video streaming, etc. A client system may be operative to
receive audio and/or visual programs via one or more such tuning
spaces, as is known in the art.
[0166] FIG. 14 illustrates a functional example of implementing a
token translation request 684 (e.g., implemented by the translation
function 682) within a database system formed of the program
database 668 and tuning space database 670. The token translation
function 682 returns local programming data 686 in response to the
translation request 684. The translation request 684, for example,
includes information sufficient to identify the PVR that is
utilizing the local programming data. The local programming data
686, for example, includes data (which may be a token) identifying
the date, time, duration, and channel that a specific program is to
be broadcast in a particular tuning space. The translation request
684, for example, may be implemented in response to a request to
record a program and/or a more general inquiry concerning local
program specifics, such as the date, time, duration, and channel
associated with a particular program in a particular tuning space.
Once the translation function 682 accesses the local programming
information for a program (or program segments) identified in the
translation request 684, the local programming data 686 is provided
in a useable format. The programming data 686 may be provided to
recording system directly (via email or a direct connection) and/or
to another remote device (e.g., remote computer 30 of FIG. 1B),
which initiated the translation request 684.
[0167] The token translation function 682 employs the translation
request 384 by locating a corresponding unique program ID in the
program database(s) 668 for the audio and/or visual program
represented by the request. Each program ID in the program database
668 may include (or be linked to) an associated database of one or
more attributes 688 that provide information about each respective
program. As mentioned above, the attributes 688 may include: a
program GUID for the program; the title of the program; a brief
description about the program; keywords associated with the
program; a list of the actors and/or actresses; the director;
information identifying the category of the program; the genre of
the program; a rating for the program (e.g., a popularity rating
and/or a classification rating); etc. The attributes 688 also may
include an image, a video clip, a URL for a related website(s), and
other data or objects that may provide useful information about the
program represented by a program ID. The attributes and other
associated program information 688 also may be returned with the
local programming data 686 so that a user may obtain additional
information about the program, if desired.
[0168] The translation request 684 and corresponding program ID are
employed to locate an appropriate local tuning space and other
local programming data so as to enable a recording system to be
programmed to record the program represented by the request. In the
example illustrated in FIG. 14, each tuning space includes a
separate tuning space database 690, 692. Each tuning space database
690, 692 further includes a channel/network database 694, 695 and a
schedule database 696, 698, respectively. Each channel/network
database 694, 695 provides a channel line-up for the respective
tuning space. Each schedule database 696, 698 stores the
programming specifics for each program ID on each channel in the
tuning space. For example, each schedule database 696, 698 may
include elements or attributes identifying each program as it is
broadcast in the corresponding tuning space, such as including its
program ID, channel ID, date, time, duration, and channel.
[0169] It is to be appreciated that each of the time and duration
fields may correspond to another database or list identifying the
time and/or duration for each program segment associated with some
or all programs. As set forth in greater detail below, a time list
and duration list may be employed to selectively combine program
segments to form a composite program, which may be an aggregation
of different programs segments arranged in a selected order. A
broadcast network may globally determine which particular program
segments to combine for a particular program or, alternatively, a
translation request 684 may contain an individual reference (e.g.,
a token) identifying each program segment and the order in which
they are to be combined. For example, the composite program may
include a combination of a network program segments and commercials
customized for an individual user or a group of users in a
particular tuning space.
[0170] In order to determine which tuning space database to access,
additional information identifying a user and/or a local tuning
space(s) associated therewith may be provided to the server 20. For
example, a PVR GUID associated with a recording system may be
submitted to the server 20 and incorporated into the translation
request 684. A PVR GUID uniquely identifies each PVR, such as may
be registered with the server 20 and stored in a user profile
database 678. The translation function 682 may employ the PVR GUID
to search the user profile database(s) 678 (FIG. 13) to locate an
appropriate tuning space database associated with a PVR so that
corresponding local programming data 686 may be provided for each
translation request 684.
[0171] While, for sake of brevity, two tuning space databases 690
and 692 are illustrated in FIG. 14, it is to be understood and
appreciated that a corresponding database may be provided for each
tuning space in which audio and/or visual programs may be
broadcast. Those skilled in the art will understand and appreciate
that other mechanisms may be employed to associate one or more
local tuning spaces with each program GUID (or other programming
information) so as to enable recording of a corresponding program
in a proper tuning space. All such mechanisms are considered to be
the within the scope of the present invention.
[0172] Data in each database 668, 690, 692 may receive update data
700 as needed. Referring between FIGS. 13 and 14, the processor 650
may include an update function or method 702 responsive to updates
or modifications in the program database 668 and/or the tuning
space databases 690-692. The update function 702 receives updated
program information, such as from another computer via the
communications device 662 or via an input device through one of its
I/O facilities 664. The update information may add to, modify, or
replace existing program characteristics of the program database
668. Alternatively, part or the entire program database 668 may be
replaced with an updated version of the database. Occasionally, a
regularly scheduled program may be interrupted or its broadcast
delayed, such as due to a presidential speech or a broadcast event
running longer than originally expected. The update function 702
thus may employ update data 700 to accommodate such changes in
program scheduling and/or to add to the appropriate tuning space
databases 690 and 692 new and/or modified program characteristics
that are being scheduled for broadcast.
[0173] The update function 702 also may be employed to notify one
or more users (e.g., by a text email message) that program criteria
for one or more programs have been updated. The update function 702
further may provide an updated version of local programming data
for some or all tokens that were previously translated from the
server. For example, each time an update is received at the server
20, the update function 702 may determine whether the update has
modified any characteristics of tokens that were previously sent.
The update function may then send (via email) a notification and/or
an updated token to each recipient requiring an update. A
modification or update may, for example, correspond to a change in
program criteria, such as the time, date, channel, etc. at which a
particular program is to be broadcast. By notifying an individual
of the change, the individual may make an informed decision
concerning whether to record the program. Alternatively, the
updated tokens may be sent directly to the recording system at each
client system to automatically accommodate any programming changes,
such as based on an address stored in the user profile database
and/or token database.
[0174] The update function 702 also may determine whether the
update includes any new tokens and whether the new program criteria
corresponds to any selection criteria in the stored selection
database 674. As mentioned above, selection criteria may be stored
in the stored selection database 674 if a search is unable to
locate a program based on the selection criteria. If the new
program criteria corresponds to stored selection criteria, a
notification or corresponding token(s) may be sent to each
individual that requested an update or, alternatively, the
notification may automatically be sent to each individual for which
corresponding selection criteria was stored in the stored selection
database 674.
[0175] As mentioned above, the server 20 may include a user profile
database 678 for storing information about a user and/or a
recording system (e.g., a PVR) associated with the user. The user
may register the PVR with the server 20. As part of a system
registration procedure, for example, a user may connect to the
server 20 (via a website or other connection) and provide
information about the user's client system, such as location
(address, zip code, etc.), the headend(s) that provides program
content to the client system, and information about the client
system (type of system, model number, etc.). The user profile
database 678, for example, may include a PVR GUID and data
identifying the tuning space(s) for each user/recording system. The
user profile database 678 enables the server applications and
functions to determine sufficient details about the local tuning
space(s) for each client system and, in turn, disseminate
appropriate local programming data 686 for each translation request
684.
[0176] Each time a token is translated, pertinent information also
may be collected and stored at the server 20, such as part of the
ratings database 676. The ratings database 676, for example, may
store information about the viewership of each program, about the
viewing history of each individual or recording system, the viewing
history within a local tuning space, etc. The server 20 may compile
and evaluate information stored in the ratings database 676 to
provide a better understanding about a viewing audience and/or
popularity of a particular program.
[0177] Because a token typically is translated for a program prior
to the program being broadcast, valuable information may be
collected in advance of the program being broadcast. The server 20,
for example, may employ predictive filtering techniques to estimate
the size and/or demographics of a viewing audience for a particular
show prior to the broadcast time of the show based on the data
stored in the ratings database 676. As a result, advertisers and
networks may better determine which advertising to utilize in
connection with a particular program. As more is known about the
size and demographics of an audience for a particular program, more
accurate rates also may be charged for such advertising broadcast
with each program.
[0178] Broadcasters and/or advertisers also may select
demographically pertinent advertisements (broadcast as program
segments) according to a stored profile of users that request
tokens and/or token translations for a specific program. The
advertisements may be implemented by providing local program data
686 for a program that includes time, date, and channel data for
program segments corresponding to the program segments requested by
a user and to program segments corresponding to advertisements
selected by the network or advertisers. The process of combining
program segments may be implemented at the server 20 in conjunction
with the local programming data 686 and used to create a composite
program. Part of (or the entire) process also may be implemented
locally at a recording system by dynamically combining program
segments in a preselected manner during playback.
[0179] The user profile database 678 also may be employed to track
program selections and/or token translation requests associated
with each client system (or user thereof), such as based on a PVR
GUID, as described above. The user profile database 678, for
example, may correlate token-related information of the database
(token requests, translation requests, etc.) with user-provided
information associated with a particular PVR. The user-provided
information, for example, may include general information about the
user, such as: the location (address) of the PVR; the user's
occupation, hobbies and other interests; programming likes and
dislikes; etc. Such user information, for example, may be collected
during a previous registration online, such as when a user
registers a system on the server 20 or from other service
providers, or offline (such as by telephone or mailing a
corresponding product registration form). Once registered, the
server 20 may track program selection criteria, tokens and other
program-related information requested or obtained by the user of a
particular PVR.
[0180] Advertising may, in turn, be customized for each PVR (or a
group of PVRS) based on the program selections stored in the user
profile database 678 and other information that may have been
gathered about each user and/or associated with each PVR GUID. As
advertisements become more interesting or incentives are provided
for watching commercials, there is less motivation for a user to
skip commercials between program segments. For example, an
incentive may be in the form of providing commercials for products
of services in which a user has expressed interest. The incentives
also may be in the form of a reward, such as redeemable (online or
offline) coupons, a reduction in a monthly service fee associated
with the user's entertainment system in exchange for watching a
certain amount of commercials, or other compensation for feedback
provided by a user (e.g., via email) in response to watching a
commercial or infomercial for a particular product or service.
Additionally or alternatively, incentives may be provided to a user
that permits a server to track programs (e.g., advertisements and
other shows) watched and listened to at the user's client system. A
database of customized commercials also may be stored at each
user's client system, which commercials are selected based on the
user profile associated with the user's client system and
dynamically inserted between program segments in a predefined
manner. Those skilled in the art will appreciate other arrangements
that may, in accordance with the present invention, be employed to
entice an individual to watch commercials on free (or discounted)
programming channels.
[0181] Program information from the ratings database 676 also may
be compiled and shared with users in a format to facilitate user
selection of programs, such as part of WHAT'S HOT webpage (FIG.
10C). The server 20 may collect and store program information
(e.g., in the program database 668 and/or the ratings database 676)
that tracks each token translation so as to provide an indication
of shows being recorded. Alternatively or additionally, each
request for a token or program GUID may be stored in the token
database 672 to provide more generalized information about the
popularity of programs about which one or more viewers may be
interested, such as based on a user obtaining a token for a
particular program. The information, for example, may be compiled
into a format to highlight popular shows, such as based on the
number of persons requesting tokens and/or translating a particular
token into programming instructions for its corresponding tuning
space. The token-related information may be made accessible at a
website associated with the server 20. A user may browse through a
visual representation of the database at a website displaying the
popular program selections from which the user may obtain one or
more tokens for selected programs.
[0182] The server 20 also may employ collaborative filtering
techniques to highlight shows that may be of interest to one or
more users. A user, for example, may subscribe to an email list for
receiving tokens for programs meeting criteria identified in
connection with an email list to which the user subscribed. An
email message may be provided to selected users (from a server or
another computer), which message includes one or more tokens
identifying popular shows and/or shows meeting selection criteria
associated with a particular list to which the user belongs. A user
also may create a customized filter at a server (e.g., server 20 or
50 of FIG. 1B) or at their client system to sort through available
programs and, in turn, provide tokens meeting selection criteria
specified by the user. The tokens, for example, may be sent to
subscribers as attachments to (or objects embedded in) email
messages.
[0183] The processor 650 also may include a token GUID generator
704 that generates a token GUID for each token sent by or obtained
from the server 20. A token GUID uniquely identifies each
respective token obtained from the server 20. The token GUID
generator 704 may store a token GUID in the token database 672 for
each token, such as in response to a request for a token and/or
when a token is translated. Other information may be linked or
associated with the stored token GUID, such as information about
individual (e.g., a PVR GUID) that requested the token or token
translation. The token GUID further may be tracked each time a
corresponding token is sent from one computer to another computer,
such as to provide an indication as to how many recipients are sent
the token. This information further may be linked with the ratings
database 676 to further provide an indication of the popularity of
a particular program. Additionally, a token GUID may be employed to
provide a link between a specific token and billing information,
such as in situations when the token corresponds to a paid-for
broadcast program. The token GUID also may be utilized as a public
key for an encrypted broadcast transmission. Those skilled in the
art will understand and appreciate other uses for which a unique ID
associated with each token may be implemented, all of which are
contemplated as falling within the scope of the present
invention.
[0184] In order to provide additional context for various aspects
of the present invention, FIG. 15 and the following discussion are
intended to provide a brief, general description of a suitable
computing environment 710 in which the various aspects of the
present invention may be implemented. While the invention has been
described above in the general context of computer-executable
instructions that may run on one or more computers, those skilled
in the art will recognize that the invention also may be
implemented in combination with other program modules and/or as a
combination of hardware and software. Generally, program modules
include routines, programs, components, data structures, etc. that
perform particular tasks or implement particular abstract data
types. Moreover, those skilled in the art will appreciate that the
inventive methods may be practiced with other computer system
configurations, including single-processor or multiprocessor
computer systems, minicomputers, mainframe computers, as well as
personal computers, hand-held computing devices,
microprocessor-based or programmable consumer electronics, and the
like, each of which may be operatively coupled to one or more
associated devices. The illustrated aspects of the invention may
also be practiced in distributed computing environments where
certain tasks are performed by remote processing devices that are
linked through a communications network. In a distributed computing
environment, program modules may be located in both local and
remote memory storage devices.
[0185] With reference to FIG. 15, an exemplary environment 710 for
implementing various aspects of the invention includes a computer
712, including a processing unit 714, a system memory 716, and a
system bus 718 that couples various system components including the
system memory to the processing unit 714. The processing unit 714
may be any of various commercially available processors, including
but not limited to Intel x86, Pentium and compatible
microprocessors from Intel and others, including Cyrix, AMD and
Nexgen; Alpha from Digital; MIPS from MIPS Technology, NEC, IDT,
Siemens, and others; and the PowerPC from IBM and Motorola. Dual
microprocessors and other multi-processor architectures also can be
used as the processing unit 714.
[0186] The system bus 718 may be any of several types of bus
structure including a memory bus or memory controller, a peripheral
bus, and a local bus using any of a variety of conventional bus
architectures such as PCI, VESA, Microchannel, ISA, and EISA, to
name a few. The computer 712 memory includes read only memory (ROM)
720 and random access memory (RAM) 722. A basic input/output system
(BIOS), containing the basic routines that help to transfer
information between elements within the computer 712, such as
during start-up, is stored in ROM 720.
[0187] The computer 712 further includes a hard disk drive 724, a
magnetic disk drive 726, e.g., to read from or write to a removable
disk 728, and an optical disk drive 730, e.g., for reading a CD-ROM
disk 732 or to read from or write to other optical media. The hard
disk drive 724, magnetic disk drive 726, and optical disk drive 730
are connected to the system bus 718 by a hard disk drive interface
734, a magnetic disk drive interface 736, and an optical drive
interface 738, respectively. The drives and their associated
computer-readable media provide nonvolatile storage of data, data
structures, computer-executable instructions, etc. for the computer
712, including for the storage of broadcast programming in a
suitable digital format. Although the description of
computer-readable media above refers to a hard disk, a removable
magnetic disk and a CD, it should be appreciated by those skilled
in the art that other types of media which are readable by a
computer, such as magnetic cassettes, flash memory cards, digital
video disks, Bernoulli cartridges, and the like, may also be used
in the exemplary operating environment, and further that any such
media may contain computer-executable instructions for performing
the methods of the present invention.
[0188] A number of program modules may be stored in the drives and
RAM 722, including an operating system 740, one or more application
programs 742, other program modules 744, and program data 746. The
operating system 740 in the illustrated computer is, for example,
the "Microsoft Windows NT" operating system, although it is to be
appreciated that the present invention may be implemented with
other operating systems or combinations of operating systems, such
as UNIX, LINUX, etc.
[0189] A user may enter commands and information into the computer
712 through a keyboard 748 and a pointing device, such as a mouse
750. Other input devices (not shown) may include a microphone, an
IR remote control, a joystick, a game pad, a satellite dish, a
scanner, or the like. These and other input devices are often
connected to the processing unit 714 through a serial port
interface 752 that is coupled to the system bus 718, but may be
connected by other interfaces, such as a parallel port, a game
port, a universal serial bus ("USB"), an IR interface, etc. A
monitor 754 or other type of display device is also connected to
the system bus 718 via an interface, such as a video adapter 756.
In addition to the monitor, a computer typically includes other
peripheral output devices (not shown), such as speakers, printers
etc.
[0190] The computer 712 may operate in a networked environment
using logical connections to one or more remote computers, such as
a remote computer(s) 758. The remote computer(s) 758 may be a
workstation, a server computer, a router, a personal computer,
microprocessor based entertainment appliance (e.g., a client
system), a peer device or other common network node, and typically
includes many or all of the elements described relative to the
computer 712, although, for purposes of brevity, only a memory
storage device 760 is illustrated in FIG. 15. The logical
connections depicted in FIG. 15 include a local area network (LAN)
762 and a wide area network (WAN) 764. Such networking environments
are commonplace in offices, enterprise-wide computer networks,
intranets and the Internet.
[0191] When used in a LAN networking environment, the computer 712
is connected to the local network 762 through a network interface
or adapter 766. When used in a WAN networking environment, the
computer 712 typically includes a modem 768, or is connected to a
communications server on the LAN, or has other means for
establishing communications over the WAN 764, such as the Internet.
The modem 768, which may be internal or external, is connected to
the system bus 718 via the serial port interface 752. In a
networked environment, program modules depicted relative to the
computer 712, or portions thereof, may be stored in the remote
memory storage device 760. It will be appreciated that the network
connections shown are exemplary and other means of establishing a
communications link between the computers may be used.
[0192] In accordance with the practices of persons skilled in the
art of computer programming, the present invention has been
described with reference to acts and symbolic representations of
operations that are performed by a computer, such as the computer
712 or remote computer(s) 758, unless otherwise indicated. Such
acts and operations are sometimes referred to as being
computer-executed. It will be appreciated that the acts and
symbolically represented operations include the manipulation by the
processing unit 604 of electrical signals representing data bits
which causes a resulting transformation or reduction of the
electrical signal representation, and the maintenance of data bits
at memory locations in the memory system (including the system
memory 716, hard drive 724, floppy disks 728, CD-ROM 732) to
thereby reconfigure or otherwise alter the computer system's
operation, as well as other processing of signals. The memory
locations where such data bits are maintained are physical
locations that have particular electrical, magnetic, or optical
properties corresponding to the data bits.
[0193] In view of the foregoing structural, functional, and
graphical features described above, methodologies in accordance
with various aspects of the present invention will be better
appreciated with reference to FIGS. 16-22. While, for purposes of
simplicity of explanation, the methodologies of FIGS. 16-22 are
shown and described as a series of steps, it is to be understood
and appreciated that the present invention is not limited by the
order of steps, as some steps may, in accordance with the present
invention, occur in different orders and/or concurrently with other
steps from that shown and described herein. Moreover, not all
illustrated steps may be required to implement a methodology in
accordance with an aspect the present invention.
[0194] FIG. 16 is a flow diagram illustrating an example of a
methodology for programming a device, such as a PVR, based on a
token. The process begins at step 800, in which a message is
received. This may correspond to, for example, receiving an email
message at the PVR, at another email address, such as a remote PC
associated with the PVR, or receiving a message by another data
communications mechanism. The process proceeds to step 802, in
which a determination is made as to whether the received message
includes any program data (e.g., tokens). If the determination is
negative, indicating that no tokens are associated with the
message, the process returns to step 800 to receive additional
messages and no action is taken with respect to the received
message without user interaction. If the determination at step 802
is affirmative, indicating that one or more tokens are associated
with the received message, the process proceeds to step 804.
[0195] At step 804, each token is extracted from the message for
further processing. Each extracted token is then authenticated
(step 806), such as by evaluating authentication data contained in
the token. Next, at step 808, a determination is made as to whether
the token(s) is authentic. Each PVR may be programmed and/or
configured to accept tokens from one or more authorized sources,
such as based on the sender's email address, a password, or other
authentication techniques. If the token(s) is not authenticated,
the process returns to step 800. A non-authenticated token may
subsequently be authenticated manually by a user, such as based on
a predefined programming authorization process (e.g., a method or
function) in which the user accepts a token. The programming
authorization may include a GUI, such as shown and described with
respect to FIG. 7. If the token(s) is determined to be authentic,
the process proceeds to step 810.
[0196] At step 810, a determination is made as to whether a token
requires local programming data to record the program represented
by the token. Local programming data may be required when the token
itself does not identify all program criteria (e.g., time, date,
channel, duration) needed to record the program in a particular
local tuning space. If the determination is affirmative, indicating
that at least some local programming data may be required, the
process proceeds to step 812. At step 812, a local database is
queried for corresponding program data necessary to program the
recording system to record the program represented by the token.
From step 812, the process proceeds to step 814.
[0197] At step 814, a determination is made as to whether
corresponding program data is present in the local database. If the
local programming data is present in the local database, the
process proceeds to step 816. At step 816, local programming data
for the program represented by the token is added to the program
list of the client system for recording the program when broadcast
in the local tuning space. Additional information also may be
stored in connection with the local programming data so that a user
may obtain information about the programs that are to be recorded.
If the determination at step 814 is negative, indicating that at
least some programming data is absent from the local database, the
process proceeds to step 818.
[0198] At step 818, the client system connects to a server for
accessing a database from which it may obtain local programming
data. Next, at step 820, a translation request is submitted, such
as described above with respect to FIG. 14. At step 822, local
programming data is received at the client system in response to
the translation request. From step 822, the process proceeds to
step 816 in which the local programming data is added to the
program list. Additionally, if the determination back at step 810
is negative, indicating that the token itself includes local
programming data for programming the associated recording system to
record the program in the local tuning space, the process advances
to step 816. From step 816, the process proceeds to step 824, in
which the program represented by the token is recorded as it is
broadcast in the local tuning space based on the stored local
programming data in the program list. As a result, the program is
recorded and stored in a storage device associated with the PVR by
storing audio and/or visual data associated with the selected
program based on the program criteria of the token. The recorded
programs are, in turn, available for viewing at a more convenient
time.
[0199] In addition to receiving messages having tokens indicative
of audio and/or visual broadcast programs, another aspect of the
present invention relates to sending tokens, such as by email, such
as according to the methodology illustrated in FIG. 17. Tokens may
be sent to any email address, such as an email address associated
with a PVR or a selected individual.
[0200] The process of FIG. 17 begins at step 830, in which a user
makes an appropriate program selection of one or more audio and/or
visual programs. By way of example, the program selection is
performed at a client system employing an EPG, such as TV-based EPG
or a simplified enhanced power EPG. The user may employ the remote
control 120 (FIG. 2) to navigate the EPG and make program
selections. The user also may navigate the Web at the client
station, such as with the remote control 120 (FIG. 2), and make
programming selections.
[0201] Alternatively, the program selection(s) may be performed
using a Web-based EPG and/or program selector, such as at a remote
computer (e.g., remote computer 30 of FIG. 1B) programmed and/or
configured for performing enhanced Web programming. The program
selector, for example, may employ a sophisticated Web-based
intelligent program selector, such as in the form of a user-defined
GUI, to provide enhanced Web content selection. The program
selector also may employ various types of program filtering, such
as collaborative filtering and editorial filtering (e.g., American
Film Institute ("AFI") filters or filters from other service
provider). The program selector also may employ historical program
selection analysis and/or other Web related content enhancements to
facilitate program selection from the content-intensive Web
according to the program interests of the user. Based on the
user-defined filters and selections made by the user, program
selections may be made from the filtered programming selections
presented by the program selector.
[0202] Referring back to FIG. 17, the process proceeds to step 832
in which a token is generated based on the program selections. As
mentioned above, the token includes program criteria, such as in
the form of an XML formatted block of information, having an
appropriate schema for identifying pertinent program information
for a corresponding segment of audio and/or visual information so
as to enable a PVR to record the program. If more than one program
has been selected (step 830), each program may be provided a
corresponding token for identifying the respective program
selection. Additionally, separate tokens may be provided for
different program segments and, if needed, for advertisements that
are to be inserted between program segments. From step 832 the
process proceeds to step 834, in which each token is associated
with a message, such as an attachment of a text email message. It
is to be appreciated that this step may occur contemporaneously
with or separately from the program selection (step 830).
[0203] Next, the process proceeds to step 836 in which each
intended recipient of the message and token(s) are identified. The
identification of recipients, for example, may be based on a
distribution list of an email GUI or by entering the email address
manually. A text and/or audio message also may be provided as part
of the message to advise the intended recipient(s) about the
token(s) and/or the program represented by the token as well as to
provide information about any other topic (see, e.g., FIG. 5).
[0204] From step 836, the process proceeds to step 838, in which
the message and associated token(s) are sent to the recipient(s) to
which the message is addressed. For example, the user may send an
email message that includes one or more tokens identifying the
selected broadcast program to an email address corresponding to the
user's own PVR. Alternatively or additionally, the user may send an
email message to another recipient having a PVR client system, such
as a colleague or friend or relative, containing one or more tokens
identifying programming content selected by the user. The email
messages and associated tokens may be sent from the computer where
the program selection criteria is entered, such as the remote
computer 30 or client system 40, or from another computer, such as
the server 20 or server 50 (FIG. 1B).
[0205] As mentioned above, a translator may be employed to
translate each token into a predetermined format corresponding to
the recipient's local tuning space. The translator may be employed,
for example, when the token is created, when it is opened by the
recipient, or at another time. The translation may be performed at
the client system, at a remote server, or a combination of
both.
[0206] Each recipient of the message sent at step 838, for example,
employs an email reader (e.g., the email GUI 400 of FIG. 5)
programmed and/or configured to read the email and view information
related to the tokens provided by the user. The email reader also
may be capable of initiating programming of a PVR by forwarding a
token, such as by one or more corresponding tokens being sent
directly to a PVR and, upon authentication, added to the program
list. As a result, programs identified by tokens may be recorded by
a PVR as they are broadcast over a local tuning space associated
with the client system. The recorded programs are maintained in
memory for viewing at a convenient time selected by the user.
[0207] While the example of FIG. 17 relates to email-based token
communications, those skilled in the art will understand and
appreciate that tokens also may be communicated by other means of
data communication in accordance with an aspect of the present
invention.
[0208] FIG. 18 illustrates a methodology for locating programs
based on selection criteria, such as may be entered in connection
with an EPG or another program selection/searching process or
method. The process begins at step 840 in which an EPG function or
other program selection mechanism is activated, such as by
selecting an EPG or accessing a suitable website with an
appropriate user interface device. From step 840, the process
proceeds to step 842 in which program characteristics are selected.
The program characteristics, for example, may include those set
forth with respect to FIG. 9 or other characteristics, such as may
be selected by a service provider. The selected program
characteristics provide selection criteria that may be employed by
an appropriate search engine. From step 842 the process proceeds to
step 846.
[0209] At step 846, a database(s) is queried based on the program
characteristics selected at step 842. The database may be part of
or associated with the server on which the EPG front end is running
or, alternatively, it may form part of or be associated with
another server. At step 848, the search results are returned in
response to the query (step 846). The search results may include
one or more programs corresponding to the program characteristics
that were selected at step 842. The search results may include
information about each program meeting the selection criteria
and/or other related information, such as links to related URLs,
tokens, images or video clips related to the program, and/or other
information that may prove useful to a user. At step 850, the
search results are displayed in connection with the EPG or other
corresponding display so that a user may view the results.
[0210] FIG. 19 illustrates an exemplary methodology for providing
one or more tokens for selected programs in accordance with an
aspect of the present invention. The process begins at step 860 in
which program information is provided to a user, such as may be
selected by the user at a remote computer or a service provider.
The process proceeds to step 862 in which the selected programs are
displayed. For example, the selected programs may be displayed in
connection with a user's personal storage bin (see, e.g., FIG. 11)
or an EPG (see, e.g., FIG. 9). From step 862 the process proceeds
to step 864.
[0211] At step 864, a determination is made as to whether a user
has selected a displayed program. If a program is selected, the
process proceeds to step 866 in which detailed program information
is displayed. The detailed information may include, for example,
information about the time, channel, duration, and cost (if any)
associated with the selected program, a description of the program,
etc. Additional information related to the selected program also
may be provided, such as URLs to related links, audio and/or video
clips related to the program, etc. From step 866 the process
proceeds to step 868. If the determination at step 864 is negative,
indicating a user has not selected a program, the process also
proceeds to step 868.
[0212] At step 868, a determination is made as to whether a program
has been selected to be sent or to be recorded. The selection may
be made in response to a user employing a user input device to
select an appropriate button (a SEND button, a RECORD button, a
PURCHASE button, a RENT button, etc.) associated with the
interactive display (see, e.g., FIGS. 9 and 11). If a selection is
made to send or record a program, the process proceeds to step 870.
At step 870 a determination is made as to whether the selected
program requires payment to view (e.g., Is it a pay program?). If
the determination at step 870 is affirmative, the process proceeds
to step 872 in which appropriate financial accounting steps are
taken to ensure proper payment for the pay program. This may
include, for example, obtaining credit card information from the
user or referring to preapproved credit information for the user.
From step 872, the process proceeds to step 874. If the
determination at step 870 is negative (indicating no payment is
required for the program), the process also proceeds to step
874.
[0213] At step 874, a message is created. The message may be an
email message created at a server or at the user's computer,
although a message (data packet) may be created in another form for
sending via another means of data communication. Next, at step 876,
a token(s) for each selected program is associated with the
message, such as an email attachment to or a component or object
embedded within the text of the email message. At step 878, one or
more recipients for the message are selected. The user may select a
recipient at this time, such as by entering an email address.
Alternatively, a service provider may provide an appropriate email
address. By way of example, when the user logs onto the system, the
user may include a user ID and password operatively linked to the
address information, although other user identification techniques
also could be used (e.g., a cookie associated with a user). This
information may be employed to access pertinent user-related data,
which may be stored in a database (e.g., a user profile database).
The user-related data may be employed to address the message, such
as with an address of the user's PVR.
[0214] From step 878, the process proceeds to step 880, in which
the message (including the token(s) and other program related
information) is sent to each recipient selected at step 878. Prior
to sending the message, however, a user may enter a personalized
message or, alternatively, a default message may be provided
indicating that the message and token(s) were sent at the request
of the user. The process then returns to step 862.
[0215] FIG. 20 illustrates a methodology, which may be implemented
at a server 20 (FIG. 1B), for providing a token in response to
selection criteria. The process begins at step 890 upon selection
criteria being received or cached into memory. As mentioned above,
the selection criteria may be entered from a remote computer or it
may be internally stored in the server 20. The process proceeds to
step 892 in which the program database is searched based on the
selection criteria. Those skilled in the art will understand and
appreciate that other databases (in the server or other computers)
also could be searched and that other searching methodologies could
be employed, in accordance with an aspect of the present invention,
to locate one or more programs matching the selection criteria.
[0216] Next, the process proceeds to step 894 in which a
determination is made as to whether a corresponding program ID
based on the selection criteria. A program ID may exist, for
example, when the program database includes programming data for a
scheduled program broadcast. If the determination at step 894 is
negative, the process proceeds to step 896. At step 896, another
determination is made as to whether a corresponding token should be
sent when it becomes available. This procedure may be implemented
in response to a user request or automatically, such as in response
to a user entering a request for a token corresponding to the
selection criteria. If it is determined that no token has been
requested to be sent when it becomes available, the process returns
to step 890. Alternatively, if a token is to be sent, the process
proceeds to step 898, in which an email address or other
appropriate identifying information is stored in connection with
the selection criteria. As a result, one or more tokens may
subsequently be sent to the stored address(es), such as after the
program database has been updated to include one or more programs
better matching the selection criteria. Other data also may be
stored in connection with the selection criteria and
user-identifying information, such as may be employed to set a time
limit during which the selection criteria may be stored.
[0217] If the determination at step 894 is affirmative, the process
proceeds to step 900 in which a token is generated. As mentioned
above, the token may include a program GUID and/or other attributes
or characteristics related to or identifying a specific program.
Next, at step 902, a corresponding token GUID is generated for the
token. The token GUID uniquely identifies the token so that the
token may be tracked and/or corresponding transaction information
may be linked back to a token request and the individual making the
request. The process then proceeds to step 904 in which the token
is provided to another computer, such as via email or download or
other means of data communication.
[0218] FIG. 21 illustrates a methodology for translating a token,
such as by a translation function running on a server in accordance
with an aspect of the present invention. The process begins at step
910 in which data is received at the server and evaluated. The
process then proceeds to step 912 in which a determination is made
as to whether the data is a translation request, such as may be
implemented by a translation function. If the data is not a
translation request the process returns to step 912 to await
another request. A proper translation request, for example,
includes sufficient information (e.g., a token) to identify a
specific audio and/or visual program. If the request is a
translation request, the process proceeds to step 914.
[0219] At step 914, one or more of the databases at the server are
queried to locate a program ID matching the program criteria
contained in the translation request. The program criteria in the
translation request may include a program ID or other data
identifying a specific program. After one or more program IDs are
located based on the selection criteria, the process proceeds to
step 916.
[0220] A step 916, each program ID is correlated with the channel
and schedule characteristics of a proper tuning space. Included
within step 916 is a determination of an appropriate local tuning
space, which may be identified from part of the translation
request, such as based on a PVR GUID or other identifying data. The
tuning space(s) associated with a translation request determines
which tuning space database(s) to employ in order to determine the
channel and scheduling details associated with the program
represented by the program ID. The process proceeds to step
918.
[0221] At step 918, local programming data is generated according
to the program ID and local tuning space information. The local
programming data, for example, may include the date, time,
duration, channel, and other associated broadcast characteristics
of the program as it is broadcast in the local tuning space. As
indicated above, the time and duration fields may correspond to
another database (or list) identifying the time and/or duration for
several program segments that comprise the intended program.
[0222] The process then proceeds to step 920, in which a
determination is made as to whether there are multiple sets of
local programming data, such as in response to plural translation
requests or when a program is defined as an aggregate of program
segments. When multiple sets of programming data exist, the process
proceeds to step 922. At step 922, each respective set of
programming data or instructions is packaged in a manner to
facilitate programming of a recording system. The packaging, for
example, may include providing computer executable instruction
indicating the order at which individual program segments are to be
combined and/or arranging each set of programming data with
appropriate header information. The process then proceeds to step
926. If the determination at step 920 is negative, the process also
proceeds to step 926.
[0223] At step 926, the local programming data is provided, such as
by email or other communication mechanisms to a computer, such as
may be identified in the translation request and/or to the computer
initiating the request. From step 926, the process proceeds to step
928 in which a PVR address is linked with the program criteria of
the translation request. This provides a mechanism to enable the
server to notify or provide an updated version of local programming
data to each recipient and/or recording system.
[0224] FIG. 22 illustrates a methodology that may be implemented by
an update function running on a computer (a server or other
computer) in accordance with an aspect of the present invention.
The process begins at step 940 with update data being received. The
update data, for example, may be entered at the computer via an I/O
facility or user input device. Alternatively or additionally, the
update may be received from a remote computer, such as via a
communications device. From step 940, the process proceeds to step
942.
[0225] At step 942, the program database is updated to reflect
changes and additions to the program data. Next, at step 944, the
tuning space database(s) is updated based on the received update
data. The update data may be utilized to implement changes in
program scheduling information, to add program criteria for
programs being newly added to a schedule, to add new channels to a
tuning space, etc. Appropriate tuning space filters also may be
employed to implement modifications and additions in each local
tuning space database in response to national or regional program
updates.
[0226] From step 944 the process proceeds to step 946, in which the
token database is searched to locate tokens for which the update
data may relate. The process then proceeds to step 948, in which a
determination is made as to whether any local programming data may
have been modified by the update data, such as that which was sent
by or obtained from the server in response to a translation
request. If the determination is negative the process advances to
step 950. If the determination is affirmative, however, the process
proceeds to step 952. At step 952, an update message is sent (e.g.,
via email). The update message, for example, may include a token
identifying the updated program, a notification about the update,
and/or an updated version of the local programming data. The update
and/or notification may be sent to each identifiable recipient of
the out-of-date data or each individual requesting an update of
such information. The address of the program data recipients, for
example, may be based a PVR GUID or other user information that may
have been provided to the server with a token translation request
or otherwise stored at the server. From step 952, the process
proceeds to step 950.
[0227] At step 950, a determination is made as to whether the
update data results in one or more tokens being added to the
program database, such as to reflect future programming not
previously indicated in the scheduling database of the tuning space
database (see FIG. 14). If no new tokens were added to the
database, the process returns to step 940. If one or more new
tokens have been added, the process proceeds to step 954. At step
954, a determination is made as to whether each newly added
token(s) corresponds to selection criteria stored in a stored
selection database. If the tokens do not match any of the stored
selection criteria, the process returns to step 940 to await
another update.
[0228] If the determination at step 954 is affirmative, indicating
that the new token matches at least one instance of the stored
selection criteria, the process proceeds to step 956. At step 766,
a message is sent (e.g., via email or other means of data
communication) to each individual identified as a proper recipient
of the token. The message may include a token corresponding to the
stored selection criteria and/or a notification that the program
data has been updated. As mentioned above, selection criteria may
be stored in response to a user presenting selection criteria to a
server that does not result in a satisfactory match to an audio
and/or visual program. Identifying information for the user may be
stored in association with the selection criteria at the user's
request or automatically, such as based on a PVR GUID or other
user-identifying information (e.g., a cookie) that may accompany
the selection criteria. It is to be appreciated that updated tokens
also may be stored at the server and be sent to a user in response
to the user contacting the server, such as by calling the server
directly or connecting to the server via a network
infrastructure.
[0229] FIG. 23 illustrates a methodology for processing program
selection data in accordance with an aspect of the present
invention, such as may be received at a server (e.g., the server 50
of FIG. 1B). The process begins at step 1000 in which program
selection data is received. The program selection may be made based
on information provided at a Website, such as by browsing the
Website with a PDA, a PC, a PVR, etc., or a program selection from
a subscription service maintained by a third party service
provider.
[0230] Next, at step 1002, the received program selection is
processed into a suitable request format. The request, for example,
may include information identifying an audio and/or visual program
(e.g., UPID, GPID) as well as other information identifying one or
more users or recording systems. As mentioned above, the other
identifying information may include a user ID, a PVR ID or address,
and/or other data (e.g., a cookie) for determining more specific
identifying information associated with one or more users and/or
client systems (e.g., information about the broadcast
services--cable, satellite, broadcast television, etc.). By way of
example, the user ID information further may include a global
identifier that facilitates roaming for a user, similar to the
Passport.TM. and Wallet.TM. services provided by the Microsoft
Corporation of Redmond, Wash.
[0231] At step 1004, the request is communicated to another
computer, such as another server (e.g., the server 20 of FIG. 1B)
through a communications system, such as the Internet. The process
proceeds to step 1006 in which local tuning space information is
determined in response to the request. The local tuning space
information in conjunction with the programming information is then
employed (step 1008) to determine corresponding scheduling data for
the selected program. The scheduling data, for example, may include
the date, time, and channel corresponding to the selected program
in an appropriate local tuning space. It is to be appreciated by
those skilled in the art that steps 1006 and 1008 may correspond to
a token translation process, such as shown and described with
respect to FIG. 21. From step 1008, the process proceeds to step
1010.
[0232] At step 1010, the scheduling data is communicated to each
recording system and/or user identified in the request. By way of
example, the scheduling data may be communicated by email, by
direct dial-up to the recording system, via TCP/IP, or any other
type of communications that may be operable to transport the
scheduling data to the identified recording system and/or user.
[0233] FIG. 24 illustrates another methodology, similar to the
methodology of FIG. 23, for processing a program selection and for
providing corresponding scheduling data to a recording system.
Steps 1000-1008 may be substantially identical to that described
with respect to FIG. 23 and, therefore, reference should be made to
the description accompanying FIG. 23 for additional details
concerning these steps.
[0234] Referring to FIG. 24, from step 1008, the process proceeds
to step 1012. At step 1012 the scheduling data is returned to the
computer, which provided the program selection request at step
1004. Next, at step 1014, the scheduling data is communicated to
each recording system identified in the request. That is, in this
example, the scheduling data is not provided directly to each
identified recording system and/or user, but instead is first
provided to the computer receiving the program selection. The
computer receiving the program selection may, in turn, forward the
scheduling data to one or more recording systems and/or users as
described herein.
[0235] What has been described above includes examples of the
present invention. It is, of course, not possible to describe every
conceivable combination of components or methodologies for purposes
of describing the present invention, but one of ordinary skill in
the art will recognize that many further combinations and
permutations of the present invention are possible. Accordingly,
the present invention is intended to embrace all such alterations,
modifications and variations that fall within the spirit and scope
of the appended claims. Furthermore, to the extent that the term
"includes" is used in either the detailed description or the
claims, such term is intended to be inclusive in a manner similar
to the term "comprising."
