Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 11/246,392, filed Oct. 7, 2005, which is a
continuation of U.S. patent application Ser. No. 10/927,814, filed
Aug. 26, 2004, which is a continuation of U.S. patent application
Ser. No. 09/354,344, filed Jul. 16, 1999, which claims the benefit
of U.S. Provisional Application No. 60/097,527, filed Aug. 21, 1998
and U.S. Provisional Application No. 60/093,292, filed Jul. 17,
1998, all of which are hereby incorporated by reference herein in
their entireties.
BACKGROUND OF THE INVENTION
[0002] This invention relates to interactive television program
guide video systems, and more particularly, to interactive
television program guide systems that provide remote access to
program guide functionality.
[0003] Cable, satellite, and broadcast television systems provide
viewers with a large number of television channels. Users have
traditionally consulted printed television program schedules to
determine the programs being broadcast at a particular time. More
recently, interactive electronic television program guides have
been developed that allow television program information to be
displayed on a user's television.
[0004] Interactive television program guides allow the user to
navigate through television program listings using a remote
control. In a typical program guide, various groups of television
program listings are displayed in predefined or user-defined
categories. Listings are typically displayed in a grid or
table.
[0005] Interactive television program guides are typically
implemented on set-top boxes located in the homes of users. A
typical set-top box is connected to the user's television and
videocassette recorder. The program guide system is therefore not
portable. As a result, the user cannot use the program guide to
adjust program reminder settings, to select programs for recording,
to purchase pay-per-view programs, or to perform other program
guide functions without that user being physically located in the
same room in the home.
[0006] On-line program guides allow users to view program listings
using a web-browser. However, the on-line program guides that are
available on the Internet do not provide the versatility of in-home
program guides. For example, on-line program guides do not allow
the user to set in-home reminders for programming, to adjust
parental control settings, or to select programs for recording on
the user's videocassette recorder.
[0007] On-line program guides have also been implemented that allow
users to order pay-per-view programs. Such systems allow users to
order programs via a web server as opposed to via the telephone or
using impulse ordering. A third party takes orders via the
internet, bills the user, and provides ordering information to the
headend. The headend authorizes the user's set-top to view the
ordered program using conventional signal denial or signal
scrambling systems without coordinating the ordering of the
pay-per-view program with an in-home guide. Ordering pay-per-view
programs in this manner (i.e., without coordinating the order with
an in-home guide), does not provide users with many of the benefits
of ordering pay-per-views through an in-home guide, such as
upcoming program reminders or missed program reminders. Users are
also not prevented from attempting to order a pay-per-view program
with a guide after the program has been ordered.
[0008] Program guides that run on personal computers are also
available. Such programs guides are useful for users who wish to
view program listings information, but who cannot readily access
their set-top-box-based program guide. For example, another member
of the user's household may be watching television and therefore
dominating the use of the set-top box and television. Because there
is no way for the user of such a personal computer program guide to
coordinate the operation of the personal computer program guide
with the operation of the set-top box program guide, the user of a
personal computer program guide is not able to use the personal
computer program guide to set in-home reminders for programming, to
adjust parental control settings, to select programs for recording
on the user's videocassette recorder, or to purchase pay-per-view
programs.
[0009] Presently existing program guide systems therefore require
that the user be physically present in the home to access important
program guide features such as program reminders, parental control,
and program recording.
[0010] It is therefore an object of the present invention to
provide an interactive television program guide system in which the
program guide may be remotely accessed by the user. Such a system
may allow the user to access important features of the user's
in-home program guide from a remote location and set program guide
settings for those features.
SUMMARY OF THE INVENTION
[0011] This and other objects of the present invention are
accomplished in accordance with the principles of the present
invention by providing an interactive television program guide
system with remote access. A local interactive television program
guide is implemented on interactive television program guide
equipment. The interactive television program guide equipment is
connected to one or more remote program guide access devices over a
remote access link. A remote access interactive television program
guide is implemented on the remote program guide access device. The
remote program guide and remote program guide access devices
provide users with the opportunity to remotely access features of
the interactive television program guide on the interactive
television program guide equipment and to remotely set program
guide settings.
[0012] Any suitable interactive television program guide function
or setting may be accessed. The remote access program guide may,
for example, provide the user with an opportunity to remotely
schedule a reminder for a program, remotely view television program
listings, remotely select programming for recordings (storage),
remotely play a stored program or a currently broadcasted program
on the remote program guide access device, remotely set and
navigate through favorites (e.g., favorite channels, program
categories, services, etc.), and remotely set parental control
settings.
[0013] The remote program guide access device may also provide the
user with an opportunity to remotely perform additional functions
such as sending and playing or displaying messages with the
interactive television program guide, polling the interactive
program guide for status information, and storing interactive
television program guide data at the remote program guide access
device.
[0014] Providing remote access to these and other features may
allow users to control television related activity in ways and in
situations in which the users could not do so before. A person who
is caught in traffic in an automobile may, for example, access the
program guide using appropriate voice commands to access listings
for programs that the user anticipates he or she will not arrive
home in time to view. The listings may be displayed on a screen, or
recited back to the user in synthesized voice listings. The user
may select any such programs for recording on their videocassette
recorder or other storage device in the home, or on a server at a
television distribution facility or other distribution facility.
Systems in which users store programs on a remote server are
described, for example, in Ellis et al. U.S. patent application
Ser. No. 09/332,244, filed Jun. 11, 1999 (Attorney Docket No.
UV-84), which is hereby incorporated by reference herein in its
entirety.
[0015] A parent may, for example, access the program guide while at
work to see if a child is watching television. If the child should
not be watching television, the parent may cause the program guide
to display a message to the child (e.g., "Go do your homework!")
and then may prevent viewing via a parental control feature. On the
other hand, if television viewing is prevented by default (e.g.,
prevented until the parent arrives home), then the parent may
remotely access the program guide to allow a child to watch
television.
[0016] A person at work may, for example, receive a call from a
spouse or other family member at home who explains to the person at
work that the person at home cannot operate home television
equipment as desired (e.g., "I can't program the VCR!"). The person
at work may remotely access the program guide, poll for equipment
status information, and perform the desired function.
[0017] If desired, non-program-guide applications may be
implemented on the user television equipment. Such
non-program-guide applications may include, for example, a web
browser application, a home shopping application, a game
application, an e-mail application, a chat application, a banking
application, etc. These applications may be implemented on a
set-top box within the user television equipment. The user may
adjust the settings of such a non-program-guide application using a
remote access device.
[0018] Further features of the invention, its nature and various
advantages will be more apparent from the accompanying drawings and
the following detailed description of the preferred
embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0033] An illustrative system 10 in accordance with the present
invention is shown in FIG. 1. Main facility 12 provides interactive
television program guide data from program guide data source 14 to
interactive television program guide equipment 17 via
communications link 18. There are preferably numerous pieces or
installations of interactive television program guide equipment 17,
although only one is shown in FIG. 1 to avoid over-complicating the
drawing. Link 18 may be a satellite link, a telephone network link,
a cable or fiber optic link, a microwave link, a combination of
such links, an Internet link, or any other suitable communications
path.
[0034] The interactive television program guide data transmitted by
main facility 12 to interactive television program guide equipment
17 may include television program listings data (e.g., program
times, channels, titles, and descriptions) and other program guide
data for additional services other than television program listings
(e.g., pay-per-view information, weather information, associated
Internet web links, computer software, etc.). Interactive
television program guide equipment 17 may be connected to remote
program guide access device 24 via remote access link 19.
Interactive television program guide equipment may have more than
one associated remote program guide access device 24, although only
one such device 24 is shown in FIG. 1 to avoid overcomplicating the
drawing.
[0035] An interactive television program guide is implemented on
interactive television program guide equipment 17. Four
illustrative arrangements for interactive television program guide
equipment 17 is shown in FIGS. 2a-2d. As shown in FIGS. 2a-2d
interactive television program guide equipment 17 may include
program guide distribution equipment 21 located at television
distribution facility 16 and user television equipment 22.
Television distribution facility 16 may be any suitable
distribution facility (e.g., a cable system headend, a broadcast
distribution facility, a satellite television distribution
facility, or any other suitable type of television distribution
facility). Television distribution facility 16 may distribute
program guide data that it received from main facility 12 to
multiple users via communications path 20.
[0036] Program guide distribution equipment 21 may be any equipment
suitable for providing program guide data to user television
equipment 22. Program guide distribution equipment 21 may include,
for example, suitable transmission hardware for distributing
program guide data on a television channel sideband, in the
vertical blanking interval of a television channel, using an
in-band digital channel, using an out-of-band digital signal, or by
any other suitable data transmission technique. Video signals
(e.g., television programming) may also be provided by program
guide distribution equipment 21 to user television equipment 22
over communications paths 20 on multiple television channels.
[0037] FIGS. 2a and 2b show illustrative arrangements for
interactive television program guide equipment 17 and remote
program guide access device 24 in systems in which program guide
data is provided to user television equipment 22 using a non
client-server based approach. For example, program guide data may
be provided by television distribution facility 16 to user
television equipment 22 in a continuous stream or may be
transmitted at a suitable time interval (e.g., once per hour). If
transmitted continuously, it may not be necessary to store data
locally at user television equipment 22. Rather, user television
equipment 22 may extract data "on the fly" as it is needed. If
desired, television distribution facility 16 may poll user
television equipment 22 periodically for certain information (e.g.,
pay program account information or information regarding programs
that have been purchased and viewed using locally-generated
authorization techniques).
[0038] In the system configuration of FIG. 2a, remote program guide
access device 24 is connected to user television equipment 22.
Television distribution facility 16 may distribute program guide
data to user television equipment 22. User television equipment 22
may transfer the program guide data to remote program guide access
device 24. User television equipment 22 may also transfer
additional data that may be necessary for allowing remote program
guide access device 24 to access various functions of the
interactive program guide (e.g., reminder information, parental
control settings, favorite channel settings, user profiles, etc.).
Any suitable distribution scheme may be used. For example, user
television equipment 22 may provide the data to remote program
guide access device 24 continuously, periodically, using a
client-server based approach, using a polling scheme, or using any
other suitable approach. Remote program guide access device 24 may
store the data if suitable for a particular transmission
scheme.
[0039] In the system configuration of FIG. 2b, remote program guide
access device 24 is connected to television distribution facility
16 via communications device 27. In this approach television
distribution facility 16 may distribute program guide data to
remote program guide access device 24 directly. Television
distribution facility 16 may also distribute additional data from
user television equipment 22 that may be necessary for allowing
remote program guide access device 24 to access various functions
of the interactive program guide (e.g., reminder information,
parental control settings, favorite channel settings, user
profiles, etc.). Television distribution facility 16 may provide
the data to remote program guide access device 24 continuously,
periodically, using a client-server based approach, using a polling
scheme, or using any other suitable approach. Remote program guide
access device may store the data if suitable for a particular
transmission scheme.
[0040] FIGS. 2c and 2d show illustrative arrangements for
interactive television program guide equipment 17 and remote
program guide access device 24 in client-server based interactive
program guide systems. As shown in FIGS. 2c and 2d, program guide
distribution equipment 21 may include program guide server 25.
Program guide server 25 may be any suitable software, hardware, or
combination thereof for providing a client-server based program
guide. Program guide server 25 may, for example, generate program
guide display screens as digital frames and distribute the frames
to user television equipment 22 for display by an interactive
program guide client implemented on user television equipment 22.
In another suitable approach, program guide server 25 may run a
suitable database engine, such a SQL server, and provide program
guide data in response to queries generated by user television
equipment 22. If desired, program guide server 25 may be located at
main facility 12 or at some other facility suitable for providing
program guide data via a program guide server (not shown).
[0041] Remote program guide access device 24 may, for example,
communicate with user television equipment 22 over remote access
link 19 as shown in FIG. 2c. Requests, commands, or other suitable
communications may be provided by remote program guide access
device 24 to user television equipment 22 and then forwarded by
user television equipment 22 to program guide server 25. Program
guide data or display screens provided by program guide server 25
may be forwarded by user television equipment 22 to remote program
guide access device 24.
[0042] Alternatively, remote program guide access device 24 may,
for example, communicate with program guide server 25 over remote
access link 19 via communications device 27 as shown in FIG. 2d.
Appropriate commands, requests, or other suitable communications
may be transmitted by remote program guide access device 24 for
processing by program guide server 25. If any changes to program
guide settings are made (e.g., a change to the parental control
settings), program guide server may, for example, update a local
program guide client running on user television equipment 22 with
the necessary information.
[0043] In the arrangements illustrated in FIGS. 2b and 2d,
television distribution facility 16 may have communications device
27 for communicating with remote program guide access device 24
over remote access link 19. Communications device 27 may be, for
example, a communications port (e.g., a serial port, parallel port,
universal serial bus (USB) port, etc.), modem (e.g., any suitable
analog or digital modem, cellular modem, or cable modem), network
interface card (e.g., an Ethernet card, token ring card, etc.),
wireless transceiver (e.g., an infrared transceiver or other
suitable transceiver), or other suitable communications device.
[0044] As shown in FIGS. 1 and 2a-2d, interactive television
program guide equipment 17 communicates with remote program guide
access device 24 via remote access link 19. In practice, remote
program guide access device 24 may be connected to user television
equipment 22 (as shown in FIGS. 2a and 2c), television distribution
facility 16 (as shown in FIG. 2b), connected to both (as indicated
in FIG. 1), or may communicate with remote program guide server 25
(as shown in FIG. 2d) via remote access link 19. Remote access link
19 may be any suitable wired or wireless communications path or
paths over which digital or analog communications may take place
between interactive television program guide equipment 17 and
remote program guide access device 24.
[0045] Each user has user television equipment 22 for displaying
the television program listings information and other program guide
data using a local interactive television program guide. There are
typically multiple pieces of user television equipment 22 and
multiple associated communications paths 20, although only one
piece of user television equipment 22 and communications path 20
are shown in FIGS. 2a-2d to avoid overcomplicating the drawing.
Television distribution facility 16 may distribute television
programming to user television equipment 22 via communications path
20. If desired, television programming may be provided over
separate communications paths (not shown).
[0046] For clarity, the present invention is illustrated, unless
otherwise indicated, in connection with a system arrangement in
which program guide data is distributed from a main facility to an
interactive television program guide implemented on user television
equipment via a television distribution facility. Other suitable
systems involve arrangements in which data is distributed to a
program guide on user television equipment using other suitable
distribution schemes, such as schemes involving data transmission
over the Internet or the like. If desired, the interactive
television program guide application may be implemented using a
client-server architecture in which the primary processing power
for the application is provided by a server located at, for
example, the television distribution facility or the main facility
(e.g., program guide server 25), and user television equipment 22
acts as a client processor as illustrated by FIGS. 2c and 2d.
Alternatively, the interactive television program guide may obtain
program guide data from the Internet. On-line program guides are
described, for example, in Boyer et al. U.S. patent application
Ser. No. 08/938,028, filed Sep. 18, 1997, which is hereby
incorporated by reference herein in its entirety.
[0047] An illustrative arrangement for user television equipment 22
is shown in FIG. 3. User television equipment 22 of FIG. 3 receives
video and data from television distribution facility 16 (FIG. 1) at
input 26. During normal television viewing, the user tunes set-top
box 28 to a desired television channel. The signal for that
television channel is then provided at video output 30. The signal
supplied at output 30 is typically either a radio-frequency (RF)
signal on a predefined channel (e.g., channel 3 or 4), or a analog
demodulated video signal, but may also be a digital signal provided
to television 36 on an appropriate digital bus (e.g., a bus using
the Institute of Electrical and Electronics Engineers (IEEE) 1394
standard, (not shown)). The video signal at output 30 is received
by optional secondary storage device 32.
[0048] Secondary storage device 32 can be any suitable type of
analog or digital program storage device or player (e.g., a
videocassette recorder, a digital video disc (DVD) player, a
hard-disk based storage device, etc.). Program recording and other
features may be controlled by set-top box 28 using control path 34.
If secondary storage device 32 is a videocassette recorder, for
example, a typical control path 34 involves the use of an infrared
transmitter coupled to the infrared receiver in the videocassette
recorder that normally accepts commands from a remote control such
as remote control 40. Remote control 40 may be used to control
set-top box 28, secondary storage device 32, and television 36.
[0049] The interactive television program guide may run on set-top
box 28, on television 36 (if television 36 has suitable processing
circuitry and memory), on secondary storage device 32 or on
optional digital storage device 31 (if they have suitable
processing circuitry and memory) or on a suitable analog or digital
receiver connected to television 36. The interactive television
program guide may also run cooperatively on both television 36 and
set-top box 28. Interactive television application systems in which
a cooperative interactive television program guide application runs
on multiple devices are described, for example, in Ellis U.S.
patent application Ser. No. 09/186,598, filed Nov. 5, 1998, which
is hereby incorporated by reference herein in its entirety.
[0050] If desired, the user may record programs and program data in
digital form on optional digital storage device 31. Digital storage
device 31 may be a writable optical storage device (such as a DVD
player capable of handling recordable DVD discs), a magnetic
storage device (such as a disk drive or digital tape), or any other
digital storage device. Interactive television program guide
systems that have digital storage devices are described, for
example, in Hassell et al. U.S. patent application Ser. No.
09/157,256, filed Sep. 17, 1998, which is hereby incorporated by
reference herein in its entirety.
[0051] Digital storage device 31 can be contained in set-top box 28
or it can be an external device connected to set-top box 28 via an
output port and appropriate interface. If necessary, processing
circuitry in set-top box 28 formats the received video, audio and
data signals into a digital file format. Preferably, the file
format is an open file format such as the Motion Pictures Expert
Group (MPEG) MPEG-2 standard. The resulting data is streamed to
digital storage device 31 via an appropriate bus (e.g., a bus using
the Institute Electrical and Electronics Engineers (IEEE) 1394
standard), and is stored on digital storage device 31. Digital
storage device 31 and secondary storage device 32 may be integrated
into a sophisticated set-top box if desired.
[0052] Television 36 receives video signals from secondary storage
device 32 via communications path 38. The video signals on
communications path 38 may either be generated by secondary storage
device 32 when playing back a prerecorded storage medium (e.g., a
videocassette or a recordable digital video disc), by digital
storage device 31 when playing back a pre-recorded digital medium,
may be passed through from set-top box 28, may be provided directly
to television 36 from set-top box 28 if secondary storage device 32
is not included in user television equipment 22, or may be received
directly by television 36. During normal television viewing, the
video signals provided to television 36 correspond to the desired
channel to which the user has tuned with set-top box 28. Video
signals may also be provided to television 36 by set-top box 28
when set-top box 28 is used to play back information stored on
digital storage device 31.
[0053] Set-top box 28 may have communications device 37 for
communicating with remote program guide access device 24 over
remote access link 19. Communications device 37 may be, for
example, a communications port (e.g., a serial port, parallel port,
universal serial bus (USB) port, etc.), modem (e.g., any suitable
analog or digital modem, cellular modem, or cable modem), network
interface card (e.g., an Ethernet card, token ring card, etc.),
wireless transceiver (e.g., an infrared transceiver or other
suitable transceiver), or other suitable communications device.
Television 36 may also have such a suitable communications device
connected to remote access link 19 if desired.
[0054] If desired, there may be multiple installations of user
television equipment 22 within the home connected via an in-home
network. This may provide for coordinating the functionality of
multiple guides within the home. Systems in which the functionality
of multiple guides are coordinated are described, for example, in
concurrently filed Ellis et al. U.S. patent application Ser. No.
09/356,161, filed Jul. 16, 1999, which is hereby incorporated by
reference herein in its entirety. In such systems, remote program
guide access device 24 may be connected via remote access link 19
to one of the guides and may provide users with the ability to
remotely coordinate the functions of all of the guides.
[0055] A more generalized embodiment of user television equipment
22 of FIG. 3 is shown in FIG. 4. As shown in FIG. 4, program guide
data from television distribution facility 16 (FIGS. 2a-2d) is
received by control circuitry 42 of user television equipment 22.
Control circuitry 42 may also send data and commands or requests
back to television distribution facility 16. The functions of
control circuitry 42 may be provided using the set-top box
arrangement of FIGS. 2a and 2b. Alternatively, these functions may
be integrated into an advanced television receiver, personal
computer television (PC/TV), or any other suitable arrangement. If
desired, a combination of such arrangements may be used.
[0056] The user controls the operation of user television equipment
22 with user interface 46. User interface 46 may be a pointing
device, wireless remote control, keyboard, touch-pad, voice
recognition system, or any other suitable user input device. To
watch television, the user instructs control circuitry 42 to
display a desired television channel on display device 45. Display
device 45 may be a television, monitor, or other suitable display
device. To access the features of the program guide, the user
instructs the program guide implemented on interactive television
program guide equipment 17 to generate a main menu or other desired
program guide display screen for display on display device 45.
[0057] User television equipment 22 of FIG. 4 may also have
communications device 51 for supporting communications between user
television equipment 22 and remote program guide access device 24
over remote access link 19. Communications device 51 may be a
communications port (e.g., a serial port, parallel port, universal
serial bus (USB) port, etc.), modem (e.g., any suitable analog or
digital standard, cellular, or cable modem), network interface card
(e.g., an Ethernet card, Token ring card, etc.), wireless
transceiver (e.g., an infrared, radio, or other suitable analog or
digital transceiver), or other suitable communications device.
[0058] User television equipment 22 may also have secondary storage
device 47, digital storage device 49, or any suitable combination
thereof for recording programming. Secondary storage device 47 can
be any suitable type of analog or digital program storage device
(e.g., a videocassette recorder, a digital video disc (DVD), etc.).
Program recording and other features may be controlled by control
circuitry 42. Digital storage device 49 can be, for example, a
writable optical storage device (such as a DVD player capable of
handling recordable DVD discs), a magnetic storage device (such as
a disk drive or digital tape), or any other digital storage
device.
[0059] An illustrative arrangement for remote program guide access
device 24 is shown in FIG. 5. As shown in FIG. 5, remote program
guide access device 24 may be any suitable personal computer (PC),
portable computer (e.g., a notebook computer), palmtop computer,
handheld personal computer (H/PC), display remote, touch-screen
remote, automobile PC, personal digital assistant (PDA), or other
suitable computer based device. Remote program guide access device
24 may have user interface 52, processing circuitry 54, storage 56,
and communications device 58. User interface 52 may be any suitable
input or output device or system, and may include a pointing
device, keyboard, touch-pad, touch screen, pen stylus, voice
recognition system, mouse, trackball, cathode ray tube (CRT)
monitor, liquid crystal display (LCD), voice synthesis processor
and speaker, or any other suitable user input or output device.
Processing circuitry 54 may include any suitable processor, such an
Intel 486 or Pentium.RTM. microprocessor. Remote program guide
access device 24 may also have storage 56. Storage 56 may be any
suitable memory or other storage device, such as RAM, ROM, flash
memory, a hard disk drive, etc.
[0060] Remote program guide access device 24 may also have
communications device 58. Communications device 58 may be any
device suitable for supporting communications between remote
program access device 24 and interactive television program guide
equipment 17 over link 19, such as a communications port (e.g., a
serial port, parallel port, universal serial bus (USB) port, etc.),
modem (e.g., any suitable analog or digital standard modem or
cellular modem), network interface card (e.g., an Ethernet card,
token ring card, etc.), wireless transceiver (e.g., an infrared,
radio, or other suitable analog or digital transceiver), or other
suitable communications device.
[0061] Remote access link 19 (FIG. 1) may include any suitable
transmission medium. Link 19 may include, for example, a serial or
parallel cable, a dial-up telephone line, a computer network or
Internet link (e.g., 10Base 2, 10Base 5, 10BaseT, 100BaseT,
10BaseF, T1, T3, etc.), an in-home network link, an infrared link,
a radio frequency link, a satellite link, any other suitable
transmission link or suitable combination of such links. Any
suitable transmission or access scheme may be used such as standard
serial or parallel communications, Ethernet, Token Ring, Fiber
Distributed Data Interface (FDDI), Circuit-Switched Cellular (CSC),
Cellular Digital Packet Data (CDPD), RAM mobile data, Global System
for Mobile communications (GSM), time division multiple access
(TDMA), code division multiple access (CDMA), any other suitable
transmission or access scheme, or any suitable combination thereof.
Preferably remote access link 19 is bidirectional. If desired,
however, certain limited program guide functions may be accessed
using a unidirectional link. An advantage of using a unidirectional
scheme for link 19 is that such schemes are generally less
complicated and then less expensive than bidirectional links.
[0062] Remote program guide access device 24 and interactive
television program guide equipment 17 may communicate over remote
access link 19 using any suitable network and transport layer
protocols, if desired. Remote program guide access device 24 and
interactive television program guide equipment 17 may communicate,
for example, using a protocol stack which includes Sequenced Packet
Exchange/Internetwork Packet Exchange (SPX/IPX) layers,
Transmission Control Protocol/Internet Protocol (TCP/IP) layers,
Appletalk Transaction Protocol/Datagram Delivery Protocol (ATP/DDP)
layers, or any other suitable network and transport layer protocols
or combination of protocols.
[0063] Remote program guide access device 24 may communicate with
interactive television program guide equipment 17 using any
suitable scheme. Remote program guide access device 24 may, for
example, connect to interactive television program guide equipment
17 using a terminal emulation scheme, such as VT100 terminal
emulation, and access the interactive television program guide as
if it were a "dumb terminal." Remote program guide access device 24
may, for example, run a standard remote access client such as a
Windows.RTM. Remote Access Services (RAS) client and may connect to
a Windows NT.RTM. Server process running on interactive television
program guide equipment 17. Any suitable combination of hardware
and software may be used. In addition to using any of the already
mentioned protocols, any number of other access, data-link,
network, routing or other protocols may be involved in supporting
communications between remote program guide access device 24 and
television distribution facility 16 over remote access link 19
(e.g., X.25, Frame Relay, Asynchronous Transfer Mode (ATM), Serial
Line Interface (SLIP), point-to-point protocols (PPP), or any other
suitable access, data-link, network, routing or other
protocol).
[0064] FIGS. 6a and 6b show illustrative arrangements for
supporting communications between remote program guide access
device 24 and interactive television program guide equipment 17
over an Internet link. Television distribution facility 16 may, for
example, include Internet service system 61 for providing
Internet-based access to the program guide. Internet service system
61 may be any combination of hardware and software capable of
providing an Internet connection to the programming guide. Remote
program guide access device 24 may establish an Internet session
with Internet service system 61 and thereby obtain program guide
data from or set program guide settings with (e.g., set reminders
or notifications, view listings, schedule program recording, set
favorites, set parental control features, send messages, poll
interactive television program guide equipment 17, etc.) the
program guide running on interactive program guide equipment 17. If
desired, Internet service system 61 may be located at a facility
that is separate from television distribution facility 16.
[0065] Program guide server 25 may, in turn, interact with the
user's client device (e.g., user television equipment 22). If the
program guide is implemented on user television equipment 22 of
program guide equipment 17 as shown in FIG. 6a, Internet service
system 61 (or other suitable equipment at television distribution
facility 16 that is connected to Internet service system 61) may
interact with user television equipment 22 directly or via program
guide distribution equipment 21 when supporting communications
between the program guide and the remote program guide access
device. If the program guide implemented on interactive television
program guide equipment 17 is a client-server guide as shown in
FIG. 6b, Internet service system 61 may interact with program guide
server 25 when supporting communications between the program guide
and the remote program guide access device 24. Alternatively,
Internet service system 61 and program guide server 25 may be the
same device or system.
[0066] In an illustrative system configuration using Internet
service system 61, remote program guide access device 24 is a
user's personal computer at work, Internet service system 61 is a
web server at a cable system headend, and user television equipment
22 at the user's home contains a set-top box on which the user's
program guide is implemented. Using this arrangement, the user may
access features of the program guide such as setting reminders or
notifications, viewing listings, program recording, setting
favorites, parental control, sending messages, polling for status,
or any other suitable function. For example, if a child in the
user's home desires permission to watch a parentally controlled
program while the user is a at work, the user may access a suitable
web page provided by Internet service system 61 that allows the
user to enter a password and adjust the program guide parental
control settings. The changed settings allowing the child access to
the desired program are then automatically transferred from
Internet service system 61 to user television equipment 22, while
the user is still at work.
[0067] As another example, the user at work may interact with the
program guide on user television equipment 22 via Internet service
system 61 to select programs for recording on the user's home
videocassette recorder, or to schedule program reminders that will
appear on the user's home television or remote program guide access
device just before a program is broadcast.
[0068] FIG. 6c shows another illustrative arrangement for remote
program guide access using the Internet. In the system arrangement
of FIG. 6c, users do not directly communicate a local guide via the
Internet as with the arrangements of FIGS. 6a and 6b. Instead,
users may have personal computer (PC) 231 as their remote access
device on which a web browser is implemented for accessing an
on-line program guide. On-line program guides are described, for
example, in above-mentioned Boyer et al. U.S. patent application
Ser. No. 08/938,028, filed Sep. 18, 1997.
[0069] Personal computer 231 may be connected to Internet service
system 235 via Internet link 233. Internet service system 233 may
use any suitable combination of computer hardware and software
capable of providing an on-line program guide server application or
web site. The user may access a personal web page and set various
program guide settings and access various program guide functions.
The user may, for example, set favorite channels, set parental
control settings, schedule programs for play back or recording by
the user's television equipment. After the user has set various
program guide settings or accessed various program guide functions
via a web page, Internet service system 235 may provide the
settings and another program guide information to Internet service
system 61 for distribution by program guide server 25 or
distribution equipment 21 (as shown) to user television equipment
22. The local guide updates its settings, records programs, plays
back programs, or performs any other suitable function accordingly.
The local guide may also order pay-per-view programs.
[0070] A remote access interactive television program guide may,
for example, be implemented on remote program guide access device
24. The remote access interactive television program guide may
communicate with the interactive television program guide that is
implemented on interactive television program guide equipment 17,
herein referred to as a "local" interactive television program
guide. The remote access and local guide may, for example, be the
same guide but compiled to run on two different platforms and to
communicate in a manner or manners discussed herein. Alternatively,
the remote access guide may be a client guide that communicates
with the local guide (i.e., a server guide). In still another
suitable approach, the two guides may be different guides that
communicate in a manner or manners discussed disclosed herein.
Generally, although not necessarily (e.g., when remote program
guide access device 24 is a personal computer as shown in FIG. 6c),
the remote access interactive television program guide may have a
reduced or limited functionality when compared to the functionality
of the local interactive television program guide. Accordingly, the
remote access guide may require less processing power and memory of
remote program guide access device 24 than the local guide requires
of interactive television program guide equipment 17.
[0071] Program guide information (e.g., reminder information,
listings information, recording information, message information,
status information, parental control settings, audio and video,
status or polling information, user information, favorites
settings, or any other information necessary for remotely providing
program guide functionality) may be exchanged, and settings set,
between the two interactive television program guides over remote
access link 19 using one or more access communications.
[0072] Access communications may include, for example, commands,
requests, messages, remote procedure calls (e.g., using a
proxy-stub pair), or any other suitable client-server or
peer-to-peer communication. Access communications may also involve,
for example, complex communications between application constructs
running on remote program guide access device 24 and interactive
television program guide equipment 17. Objects running in the two
versions of the program guides, for example, may communicate using
an Object Request Broker (ORB). The program guide information may,
for example, be encapsulated as component object model (COM)
objects and persisted to files that are transmitted over remote
access link 19. In another approach, access communications may
include HTML formatted markup language documents (e.g., web pages),
that are exchanged between remote program guide access device 24
and interactive television program guide equipment via Internet
service system 61.
[0073] Program guide information may be transferred, and program
guide settings set, between remote program guide access device 24
and interactive television program guide equipment 17 using any
suitable application layer protocol if desired. If link 19 is an
Internet link, for example, program guide functionality may be
accessed by, for example, using the Hypertext Transfer Protocol
(HTTP). Remote program guide access device 24 and interactive
television program guide equipment 17 may, for example, transfer
program guide information as files using the File Transfer Protocol
(FTP) or Trivial File Transfer Protocol (TFTP), running over a
TCP/IP protocol stack. Any suitable file transfer protocol based on
any suitable protocol stack may be used.
[0074] Remote program guide access device 24 and interactive
television program guide equipment 17 may also exchange program
guide data and other information as messages using any suitable
messaging scheme or messaging application programming interface
(API). Program guide data and other information may, for example,
be encapsulated into e-mail messages and transferred using the
Simple Mail Transfer Protocol (SMTP), Messaging API (MAPI), or
other suitable messaging protocol or API.
[0075] Remote program guide access device 24 and the interactive
television program guide implemented on interactive program guide
equipment 17 may exchange access communications to provide the user
with access to program guide functionality as if the program guide
were running locally on remote program guide access device 24.
Remote program guide access device 24 may provide a user with
access to any number of program guide functions such as accessing
programming information, scheduling reminders for programs, setting
and navigating through favorite channels, setting parental control
settings, scheduling programming recordings, or any other program
guide function to the extent allowed by the resources of remote
program guide access device 24. If desired, remote program guide
access device 24 may allow the user to perform other program guide
functions, such as determining the status of user television
equipment 22, sending messages to user television equipment 22,
interacting with peripherals connected to user television
equipment, and other suitable functions.
[0076] When the user wishes to access the features of the program
guide via remote program guide access device 24, the user may issue
an appropriate command using user interface 52 (FIG. 5). For
example, if the user wishes to view programming information, a
"guide" key on user interface 52 can be used. If, for example, user
interface 52 includes a microphone and uses suitable voice
recognition software, the user may speak a predetermined command
into the microphone. Such an interface is especially useful in
environments where remote program guide access device 24 must be
operated without the use of one's hands, as with an automobile
PC.
[0077] When possible, remote program guide access device 24 may
present program guide data and other information to the user as
they are normally presented by user television equipment 22. In
practice, appropriate differences in presentation may occur
depending on the interface devices used in user television
equipment 22 and remote program guide access device 24 (e.g., user
television equipment 22 may use a television to output listings and
remote program guide access device 24 may include a voice
recognition and synthesis system to output synthesized voice
listings).
[0078] When a user indicates a desire to access program guide
features by issuing an appropriate command to remote program guide
access device 24, remote program guide access device 24 may, for
example, access stored program guide information or obtain program
guide information from interactive television program guide
equipment 17 via remote access link 19 using any of the approaches
already described, and generate an appropriate display screen for
display using user interface 52. Alternatively, the local
interactive television program guide implemented on interactive
television program guide equipment 17 may receive one or more
access communications from remote program guide access device 24
over link 19, generate the appropriate program guide display
screen, and send the program guide display screen back to remote
program guide access device 24 for display on user interface 52. In
another embodiment, a remote access guide may run on remote program
guide access device 24 and issue access communications over remote
access link 19 as if it were running as a client locally on
interactive television program guide equipment 17. In another
embodiment, remote program guide access device 24 may access a web
site and view web pages that contain program guide information.
[0079] The remote access program guide running on remote program
guide access device 24 may provide a user with an opportunity to
remotely access program listings. A person driving an automobile,
for example, may issue a suitable vocal command that is recognized
by interface 52. The remote access program guide may issue one or
more access communications to the local program guide, which in
turn supplies program listings information back to remote program
guide access device 24. User interface 52 may, for example, provide
the listings to the user in synthesized voice outputs.
[0080] The program listings may also, for example, be displayed in
a program listings screen by a suitable display device. A program
listings screen may contain one or more lists of programs organized
according to one or more organization criteria (e.g., by program
type, theme, or any other predefined or user defined and selectable
criteria) and sorted in various ways (e.g., alphabetically). One
approach is to organize program listings into a program listings
grid. As shown in FIG. 7, program listings display screen 148 may
contain program listings area 168. Program listings area 168 may
display television program listings in any suitable format, such as
any suitable list, table, or grid.
[0081] FIG. 7 illustrates the display of program listings in
program listings grid 150. Program listings grid 150 may be divided
into a number of columns 162 which correspond to program broadcast
times and which may be equally spaced apart (e.g., in thirty-minute
steps). Program listings may be displayed in the grid in sub-sets
according to predefined or selectable organization criteria and
sorted in various ways. Program listings row 152 contains, for
example, selectable program listings for THE DESERTS OF AFRICA and
WILDLIFE on channel 46 (Public Television). Program listings row
154 contains, for example, selectable program listings for GHOST
and TITANIC on channel 47 (HBO). Program listings row 156 contains,
for example, selectable program listings for programs BLUES
BROTHERS on channel 48 (VH-1). Program listing row 158 contains
selectable program listings for programs, PPV 1, and PPV 2 on
channel 49 (ADU). Program listings row 160 contains a selectable
program listing for COOKING on channel 50 (WPTU). The programs on
each channel are typically different.
[0082] Program listings grid 150 may have movable cell highlight
region 151, which highlights the current grid cell. The user may
position highlight region 151 by entering appropriate commands with
user interface 52. For example, if user input interface 52 has a
keypad, the user can position highlight region 151 using "up,"
"down," "left," and "right" cursor keys. Remote program listings
may also be panned left, right, up, and down by positioning
highlight region 151 using the cursor keys on user interface 52.
Alternatively, a touch sensitive screen, trackball, voice commands,
or other suitable device may be used to move highlight region 151
or to select program listings without the use of highlight region
151. In still another approach, the user may speak the title of a
television program listing into a voice request recognition system
which will issue an appropriate command or request to remote
program guide access device 24. Any other suitable approach may
also be used.
[0083] After a user selects a program listing, the remote access
program guide may provide the user with the opportunity to access a
number of program guide features. For example, the user may access
additional information (typically text or graphics, but possibly
video if desired) about the listing, schedule an associated program
reminder, schedule an associated program for recording by one or
more of digital storage device 31 (FIG. 3), secondary storage
device 32 (FIG. 3), storage 56 (FIG. 5), or program guide server
25.
[0084] Program listings may also be displayed for the user in a
list. FIG. 8 illustrates a program listings display screen having a
program listings list displayed in accordance with the principles
of the present invention. Scrollable program listings lists may
display program listings in subsets according to predefined or
user-selected organization criteria. Any suitable organization
criteria and sorting scheme may be used. Scrollable program
listings list 170 of FIG. 8, for example, organizes program
listings according to program type and then sorts the listings
alphabetically in each subset. The television program listings
display screen of FIG. 8 also has movable cell highlight region 171
for moving within the list and selecting listings.
[0085] The remote access program guide may also provide a user with
the opportunity to remotely schedule program reminders when the
user indicates a desire to set a program reminder (e.g., by
pressing a "reminder" button on user interface 52, selecting an on
screen "reminder" button, issuing an appropriate vocal command,
etc.). The remote access program guide may transmit one or more
access communications to the local interactive television program
guide implemented on interactive television program guide equipment
17 to schedule the reminder. Alternatively, the remote access
program guide may, for example, store a reminder locally on storage
56 of remote program guide access device 24 (FIG. 5). Information
indicating the user who set the reminder may also be stored on
interactive program guide equipment 17 or storage 56. Reminders may
also be scheduled by a user with the local guide, transmitted to
remote program guide access device 24, and displayed by the remote
access guide on remote program guide access device 24.
[0086] At an appropriate time before the selected program is
scheduled to air (e.g., a predefined user-selectable number of
minutes, hours or days), a reminder may be issued by the local or
remote interactive television program guides, or both. The reminder
may be issued on all remote program guide access devices 24
available to the user, and may be displayed (e.g., in the form of a
pop-up window or message) on user television equipment 22. If a
reminder for a program is to be displayed on the user's home
television, the reminder may be displayed just before the beginning
of the program. If a reminder for a program is to be displayed on
remote program guide access device 24, the reminder may be
displayed much earlier (e.g., several hours before the
program).
[0087] In another approach, reminders may be sent as e-mail
messages from the interactive television program guide to remote
program guide access device 24. Interactive program guide systems
in which reminders are sent to users via e-mail are described, for
example, in Boyer et al. U.S. patent application Ser. No.
08/987,740, filed Dec. 9, 1997, which is hereby incorporated by
reference herein in its entirety. In still another approach, user
interface 52 may include an alphanumeric pager (among other
suitable devices for providing bi-directional communications with
the program guide via remote access link 19). The interactive
program guide implemented on interactive television program guide
equipment 17 may phone an automatic paging service (e.g., by using
a suitable modem and communications software), and issue a message
similar to the one contained in notification 177. An illustrative
reminder 177 for display on display device 45 (FIG. 4) or user
interface 52 (FIG. 5) is shown in FIG. 9.
[0088] The remote access program guide may also provide a user with
the opportunity to remotely access and adjust the parental control
settings of the local interactive television program guide
implemented on interactive television program guide equipment 17.
The remote access program guide, for example, may provide users
with an opportunity to block potentially objectionable programs or
channels using a parental control code (e.g., a personal
identification number (PIN) code). Users my also selectively unlock
blocked channels or programs. If desired, the user may remotely
access parental control settings related to blocking the display of
potentially objectionable program listings.
[0089] The remote access program guide may obtain parental control
information (e.g., which channels, services, programs, genres or
types of program listings may be locked, maximum rating
information, PIN information, etc.), from the local program guide
implemented on interactive television program guide equipment 17
over remote access link 19 in any suitable manner. Remote program
guide access device 24 may, if desired, store parental control
information on storage 56. Information indicating the user who
accessed and adjusted parental control settings may be stored by
the program guide or remote program guide access device 24.
[0090] Remote program guide access device 24 may provide a user
with the opportunity to remotely parentally control television
programming by, for example, providing the user with the
opportunity to select a television program listing and issue an
appropriate command using user interface 52 (e.g., by pressing a
displayed "lock" button, using a pointing device or touch sensitive
screen, issuing an appropriate vocal command, etc.). Remote program
guide access device 24 may indicate to a user that a channel,
service, program, or genre is locked by, for example, generating an
appropriate notice, icon, synthesized voice response, message, or
any other suitable indication. FIGS. 7 and 8 illustrate the use of
lock icon 310 for indicating, for example, that television service
ADU is locked.
[0091] The remote access program guide may also provide users with
an opportunity to remotely access interactive television program
guide functionality related to user preferences or "favorites"
settings. For example, remote program guide access device 24 may
access features for setting-up and navigating through favorite
channels or programs. Interactive television program guide systems
in which program guide data is displayed according to preference
profiles are described, for example, in Ellis et al. U.S. patent
application Ser. No. 09/034,934, filed Mar. 4, 1998, which is
hereby incorporated by reference herein in its entirety.
[0092] The remote access program guide may obtain information on
the user's preferences (e.g., which channels or programs are
favorites, favorite themes, likes and dislikes etc.) from the local
interactive television program guide implemented on interactive
television program guide equipment 17 in any suitable manner. The
remote access program guide may, if desired, store favorites
information on storage 56 (FIG. 5), may provide the user with an
opportunity to remotely adjust channel settings and other
preferences based on the favorites information. Remote program
guide access device 24 may transmit changed or new favorites
information to interactive television program equipment 17 via
remote access link 19 using one or more access communications.
Information indicating the user who changed the profiles may also
be stored by the local or remote access program guides.
[0093] The information on the user's preferences may be used by the
local and remote access interactive program guides to navigate
through favorite channels and display television program listings.
FIG. 10 shows an illustrative program listings display screen that
may be displayed by the remote access program guide on remote
program guide access device 24 using user interface 52. The display
screen includes a number of channels that have been selected as
favorites (e.g., channels 2, 4, 7, 47 and 48). Alternatively,
remote program guide access device 24 may, for example, display
television program listings in a grid, table, or list while
highlighting favorite channels or preferred programs. A user may be
provided with the opportunity to "scroll" between favorite listings
or channels by issuing an appropriate command using user interface
52. In still another suitable approach, remote program guide access
device 24 may display program guide data for only those programs or
channels that are of interest to users as defined by the
profiles.
[0094] User preference profiles may also be used to limit the
amount of data provided to remote program guide access device 24
and thereby tend to minimize the bandwidth requirements of remote
access link 19. Data filtering may be performed, for example, by
the local interactive guide according to the user profiles when
transferring data to remote program guide access device 24. Only
data for those programs or channels that are of interest to the
user may be transferred if desired. Alternatively, data filtering
may be performed, for example, by program guide server 25 or
Internet service system 61.
[0095] The remote access program guide may also provide the user
with the opportunity to remotely schedule recordings using the
local interactive program guide. The user may, for example, select
a program listing using user interface 52 (FIG. 5) and issue an
appropriate command (e.g., pushing an on-screen "button," issuing
an appropriate voice command, etc.). The remote access program
guide may respond by sending one or more access communications to
the local interactive program guide implemented on interactive
television program guide equipment 17 with the remote program guide
access device 24 to record the program associated with the selected
listing when the program is aired. The local program guide may
store the program on secondary storage device 32, digital storage
device 31, or on storage 56 of remote program guide access device
24. Information indicating the user who scheduled a program for
recording may also be stored by the program guide or remote program
guide access device 24. If the programming is stored on storage 56,
it may be transmitted to remote program guide access device 24 in
any suitable format (e.g., as National Television Standards
Committee (NTSC) video, as MPEG-2 files, etc.), and may be
converted to a digital format by a suitable analog to digital
converter in remote program guide access device 24 if necessary
(not shown). Any suitable transmission scheme may be used, such as
using FTP if files are transferred, for example, across an Internet
link. Programs may also be recorded by program guide server 25.
Program guide systems in which user selected programs are stored by
a program guide server are described, for example, in
above-mentioned Ellis et al. U.S. patent application Ser. No.
09/332,244, filed Jun. 11, 1999.
[0096] If desired, program series may be recorded. Interactive
television program guide systems in which program series are
recorded are described, for example, in Knudson et al. U.S. patent
application Ser. No. 09/330,792, filed Jun. 11, 1999, which is
hereby incorporated by reference herein in its entirety.
[0097] Program guide information may also be stored by the remote
access interactive television program guide on storage 56. User
settings and profiles, video clips, and detailed descriptive
information may also be stored. Storing programming or data on
storage 56 may be appropriate in situations, for example, where the
data is required to be maintained across a power outage, or if the
volume of data that the interactive program guide must store during
normal operation is more than interactive television program guide
equipment 17 can handle.
[0098] The remote access program guide may also provide a user with
an opportunity to remotely order pay-per-view programs and
packages. The remote access program guide may, for example, provide
the user with an opportunity to select a pay-per-view program or
package listing using user interface 52 (e.g., by using a pointing
device, touch sensitive screen, or issuing a voice command to
select a pay-per-view program listing). In response to the user
command, remote program guide access device 24 may obtain
pay-per-view information (e.g., price, ordering information, time,
event code, etc.) from the interactive television program guide
running on interactive television program guide equipment 17, via
remote access link 19. Alternatively, the pay-per-view information
may have been provided to remote program guide access device 24 by
the local guide, program guide server 25, or Internet Service
system 61.
[0099] The remote access program guide may provide the pay-per-view
information to the user using user interface 52, and may provide
the user with the opportunity to order the pay-per-view selection.
Once the user issues an appropriate command to remote program guide
access device 24 to order the pay-per-view selection, the remote
access guide on remote program guide access device 24 may indicate
to the local guide implemented interactive program guide equipment
17 (e.g., via one or more access communications) the program that
the user wishes to order. The local interactive program guide may
respond by ordering the pay-per-view program from television
distribution facilitating 16 or some other distribution facility.
Alternatively, the remote access program guide may order the
pay-per-view program from television distribution facility 16 (or
some other distribution facility) and indicate the ordered
pay-pay-view to the local guide so that ordering related functions
may be coordinated.
[0100] Remotely ordering pay-per-view programs via the local
interactive guide as opposed to ordering pay-per-view programs
directly from a headend by phone, internet, or impulse ordering
using the remote access guide may allow the local program guide to
perform functions that it would not ordinarily be able to perform.
Ordering a pay-per-view through the local guide as opposed to
directly from television distribution facility 16 may allow the
local guide to, for example, parentally control the ordering of a
program, inform the user that the program is about to start, inform
the user that the user has missed an ordered pay-per-view program,
provide the user with an opportunity to reorder the program, or any
other suitable function associated with ordering a pay-per-view
program.
[0101] The remote access program guide may also provide the user
with an opportunity to remotely access video and audio (either
together or separately) that is being distributed to the local
interactive television program guide or which has been stored by
the local interactive television program guide on user television
equipment 22 or at a remote server. In response to an appropriate
user command on user interface device 56, the remote access program
guide may, for example, query the interactive television program
guide for media directory information stored on digital storage
device 31 or secondary storage device 32. Interactive television
program guides which store programming using a digital media
directory are described, for example, in the previously mentioned
Ellis et al. U.S. patent application Ser. No. 09/157,256.
[0102] The remote access program guide may provide the user with
the opportunity to select a directory entry or may, for example,
provide the user with an opportunity to select a program listing of
a television program that is being broadcast. In response to either
selection, the remote access program guide may issue an appropriate
access communication to the interactive television program guide to
play back or tune to the selection and transmit it back to remote
program guide access device 24 over remote access link 19. Remote
program guide access device 24 may play the video or audio for the
user. In one approach, for example, remote program guide access
device 24 may provide a user with the opportunity to access audio
from a digital music channel which is received by interactive
television program guide equipment 17, and play the audio on a
speaker or by using an audio device that may be contained in user
interface 52 (e.g., a car stereo).
[0103] Video and audio may be transmitted from interactive
television program guide equipment 17 to remote program guide
access device 24 over remote access link 19 in any suitable format
(e.g., as NTSC video, as MPEG-2 files, using the M-bone, etc.), and
may be converted to a digital format if necessary by a suitable
analog to digital converter in remote program guide access device
24 (not shown). Any suitable transmission scheme may be used.
[0104] The remote access program guide may also provide a user with
the opportunity to poll the local interactive television program
guide to determine the status of interactive television program
guide equipment 17 or, more specifically, user television equipment
22. For example, the remote access program guide may obtain
information regarding whether the interactive television program
guide is in use, what channel user television equipment 22 is tuned
to, the title of the current program, the rating of the current
program, the status of remote access link 19, available devices,
etc. Any suitable scheme may be used, such as using a Simple
Network Management Protocol (SNMP) approach in which a management
client process runs as part of the interactive television program
guide implemented on interactive television program guide equipment
17, and in which a management server process runs on remote program
guide access device 24.
[0105] When the user issues an appropriate command using user
interface device 56 (e.g., by pressing a button on a key pad,
selecting an on-screen option or button, issuing an appropriate
voice command, etc.), the remote access program guide may respond
by issuing an access communication to the interactive program guide
over remote access link 19 using remote program guide access device
24. The interactive program guide may respond by transmitting the
desired status information back to remote program guide access
device 24 over remote access link 19, or by transmitting a display
screen (if appropriate). The remote access program guide may
indicate the status of interactive television program guide
equipment 17 on remote program guide access device 24 using any
suitable indicator (e.g., a display screen, synthesized voice
responses, etc.). An illustrative status display screen 200 for
display using user interface 52 is shown in FIG. 11.
[0106] The remote access program guide may also provide a user with
an opportunity to control user television equipment 22 remotely. A
user may, for example, position highlight region 201 over a
setting, select the setting, and change its value. The user may,
for example, change the current channel, the current volume, or
control user television equipment 22 in any other suitable
manner.
[0107] The remote access program guide may also provide a user with
the opportunity to send audio, graphical, and text messages to the
local interactive program guide for playing or display by user
television equipment 22. For example, the remote access program
guide may receive a voice message from the user using user
interface device 24. That voice message may be converted to a
digital signal by an analog-to-digital converter in remote program
guide access device 24 if necessary, and sent to the interactive
television program guide over remote access link 19. Once received,
the local interactive television program guide may play (or
display) the message on user television equipment 22. If desired,
messages created by a user on the local interactive television
program guide or by an operator of television distribution facility
16 may be sent to remote program guide access device 24. The remote
access program guide may in turn provide the messages to the user
using remote program guide access device 24.
[0108] FIGS. 12-24 are illustrative flow charts of steps involved
in providing remote access to functions of a local interactive
television program guide in accordance with the principles of the
present invention. The steps shown in FIGS. 12-24 are illustrative
and may be performed in any suitable order. Moreover, in practice
it may be desirable to combine or delete various steps or
combinations of steps shown in the flow charts.
[0109] FIG. 12 shows illustrative steps involved in providing
remote access to the various program guide functions. At step 1200,
a remote access link is established between the remote access
program guide implemented on remote program guide access device 24
and the interactive television program guide implemented on
interactive television program guide equipment 17 using remote
access link 19. At step 1210, the remote access program guide
provides the user with the opportunity to remotely access functions
of the interactive program guide over the remote access link.
[0110] The remote access program guide may, for example, obtain a
user command from the user that indicates a desired program guide
function using remote program guide access device 24 (substep 1265)
and then remotely provide the indicated program guide function to
the user. A user may indicate a desired function by entering an
appropriate command using user interface 52. The user may, for
example, enter a command using a keyboard, speak a command into a
microphone, select an on-screen button using a pointing device, or
any other suitable approach.
[0111] The indicated program guide function may be remotely
provided to the user audibly (substep 1270) using, for example, a
speaker, car stereo, or other device capable of producing sounds
that suitably indicate to the user program guide information.
Alternatively, the indicated program guide function may be remotely
provided to the user visually (at substep 1280), for example, by
using a monitor, LCD, or other display device.
[0112] Establishing the remote access link between the remote
access program guide and the local interactive television program
guide implemented on interactive television program guide equipment
17 as indicated by step 1200 and providing the user with an
opportunity to remotely access functions of the local interactive
television program guide over remote access link 19 (step 1210) may
depend on the configuration of the interactive television program
guide system. FIGS. 13a-13e show illustrative variations of steps
1200 and 1210 of FIG. 12 for establishing remote access link 19 and
for providing the user with remote access to program guide
functions for the illustrative systems 10 of FIGS. 2a-2d and FIGS.
6a-6c.
[0113] FIG. 13a illustrates steps involved in establishing remote
access link 19 and for providing the user with remote access to
program guide functions in the systems of FIGS. 2a and 2c. In these
systems, remote access link 19 may be established between the
remote access program guide and the interactive television program
guide via a communications device in user television equipment 22
(Step 1200a). The local interactive television program guide may be
wholly implemented on user television 22 as in system 10 of FIG.
2a, or may be partially implemented on user television equipment 22
as, for example, an interactive program guide client, as in system
10 of FIG. 2c. At step 1210a, remote program guide access device 24
may provide the user with the opportunity to remotely access the
functions of the local interactive television program guide over
the remote access link with a communications device.
[0114] Remote access link 19 may be established between the remote
access program guide and the interactive television program guide
via remote program guide access device 24 and a communications
device in television distribution facility 16 or other location for
a system configured as shown in FIG. 2d. Providing remote access to
the functions of the local interactive television program guide in
such a system may, for example, involve the steps shown in FIG.
13b. At step 1200b, for example, remote access link 19 may be
established with a communications device in television distribution
facility 16. The remote access program guide may, for example,
provide the user with the opportunity to remotely access functions
of the program guide with a communications device in the television
distribution facility 16 at step 1210b.
[0115] If television distribution facility 16 includes a program
guide server as shown in FIG. 2c, remote access link 19 may be
established between the remote access program guide and the
interactive television program guide via remote program guide
access device 24 and a communications device in television
distribution facility 16 as indicated by step 1200c of FIG. 13c. At
step 1210c remote program guide access device 24 may, for example,
provide the user with the opportunity to remotely access the
functions of the program guide over remote access link 19 with a
communications device in distribution facility 16.
[0116] Steps involved in establishing remote access link 19 in
on-line program guide systems that communicate with the remote
access program guide such as in systems 10 of FIGS. 6a and 6b are
shown in FIGS. 13d and 13e. In the on-line program guide system of
FIG. 6a, for example, remote access link 19 may be established
between the local interactive television program guide and the
remote access program guide with Internet service system 61 (step
1200d, FIG. 13d). In the client-server on-line program guide system
of FIG. 6b, for example, remote access link 19 may be established
between the local interactive television program guide and the
remote access program guide with an Internet service system in
contact with program guide server 25 (step 1200e, FIG. 13e). The
remote access program guide may provide the user with the
opportunity to remotely access the functions of the program guide
at steps 1210d and 1210e of FIGS. 13d and 13e, respectively.
[0117] Establishing remote access link 19 at step 1200 of FIG. 12
may also involve exchanging one or more access communications
between the interactive television program guide implemented on
interactive television program guide equipment 17 and the remote
access program guide implemented on remote program guide access
device 24, as indicated by substep 1202 of FIG. 14. Access
communicators may include any client-server or peer-to-peer
communication construct suitable for providing program guide
information across remote access link 19. Access communications may
include, for example, requests, commands, messages, or remote
procedure calls, as indicated by substeps 1204, 1205, 1206, and
1207, respectively.
[0118] Access communications may also involve complex
communications between application constructs running on remote
program guide access device 24 and interactive television program
guide equipment 17. Access communications may, for example, be
object based, as indicated by substep 1208. Objects running in two
program guides, for example, may communicate using an Object
Request Broker (ORB). The program guide information may, for
example, be encapsulated as component object model (COM) objects
and persisted to files that are transmitted over remote access link
19. Access communications may also include, for example, HTML
formatted markup language documents (e.g., Web pages), that are
exchanged between remote program guide access device 24 and
interactive television program guide equipment 17 via Internet
service system 61, as indicated by substep 1209.
[0119] FIGS. 15-23 are flowcharts of illustrative steps involved in
providing remote access to a number of specific program guide
functions. Remote access to the functions may be provided in any
interactive television program guide system, such as a system 10
having the arrangements of interactive television program guide
equipment 17 shown in FIGS. 2a-2d and FIGS. 6a and 6b. The steps
shown in FIGS. 12-14 are not shown in the flowcharts of FIGS. 15-23
to avoid over-complicating the drawings, although any suitable
combination or combinations of the steps of the flowcharts of FIGS.
12-23 may be used in practice.
[0120] FIG. 15 shows illustrative steps involved in remotely
providing program listings information to a user. At step 1600,
program listings information is remotely obtained from the local
interactive television program guide implemented on interactive
television program guide equipment 17 via remote access link 19.
The remote access program guide may, for example, obtain this
information on startup, periodically, continuously, on demand in
response to a suitable user command, or using any other suitable
scheme using remote program guide access device 24.
[0121] At step 1610, the program listings information may be
provided to the user. The program listings information may be
displayed for the user by the remote access program guide in a
table, listing grid, or other suitable construct, using user
interface 52 (substep 1620). Alternatively, program listings
information may be provided audibly for the user by using, for
example, a speaker (substep 1630).
[0122] At step 1640, the remote access program guide may provide
the user with the opportunity to select a program listing. In
response to such a selection, the remote access program guide may
provide the user with the opportunity to access other remote
program guide features for the listing (e.g., displays additional
info, schedule a program reminder, record, parental control, order
the program if it is a pay-per-view program, etc.).
[0123] FIG. 16 shows illustrative steps involved in providing the
user with remote access to the program reminder feature of a local
interactive television program guide. At step 1700, a user is
provided with an opportunity to schedule a programming reminder.
The user may be provided with an opportunity to remotely schedule a
programming reminder with the local guide or with the remote access
guide. This opportunity, may, for example, be provided in response
to the user selection of a program listing. At step 1710, the
program reminder is scheduled by the local guide or the remote
access guide. The program reminder may be scheduled with the local
interactive television program guide (substep 1720), may be stored
by the remote access interactive television program guide (substep
1730), or both.
[0124] At step 1740, the program reminder is generated at an
appropriate time (e.g., a predefined or user-selectable number of
minutes, hours, or days) before a program is scheduled to air. The
reminder may be generated by the local interactive television
program guide implemented on interactive television program guide
equipment 17, or may be generated by the remote interactive
television program guide. The program reminder may, for example, be
sent to the user via e-mail or alphanumeric page, as indicated by
substeps 1750 and 1760 respectively.
[0125] FIG. 17 shows illustrative steps involved in providing a
user with remote access to the parental control features of the
local interactive television program guide implemented on
interactive television program guide equipment 17. At step 1800,
parental control information is remotely obtained. This may occur,
for example, on startup, periodically, continuously, on demand in
response to a suitable user command, or using any other suitable
scheme.
[0126] The remote access program guide may provide the user with
the opportunity to parentally control programming (e.g., by
program, channel, theme, time, etc.) in any suitable manner (step
1810). At step 1820, the remote access program guide remotely sets
a parental control setting with the interactive television program
guide via remote access link 19. Remote program guide access device
24 may use, for example, one or more access communications sent
over remote access link 19 to exchange the parental control
settings with interactive television program guide 17.
[0127] Programming may be locked locally by a user via user
television equipment 22, or may have been locked remotely by the
remote access program guide. The remote access program guide may
indicate to a user that programming is locked (e.g., by program,
channel, theme, etc.) with remote program guide access device 24 at
step 1830. Remote program guide access device 24 may use, for
example, a notice, icon, synthesized voice output, message, or any
other suitable indicator.
[0128] FIG. 18 shows illustrative steps involved in providing a
user with remote access to the favorites and user profile functions
of the interactive television program guide implemented on
interactive television program guide equipment 17. At step 1900,
user preference profiles are remotely obtained from the local
interactive television program guide by the remote access
interactive television program guide via remote access link 19. The
information or profiles may be obtained, for example, on startup,
periodically, continuously, on demand in response to a suitable
user command, or using any other suitable scheme.
[0129] The remote access program guide may provide the user with
the opportunity remotely adjust user profiles (step 1910). The user
may, for example, add or delete favorite channels, themes, indicate
likes or dislikes, etc. At step 1920, the remote access program
guide remotely adjusts user profiles with the local interactive
television program guide. This may be accomplished by, for example,
remote program access device 24 exchanging one or more access
communications with interactive television guide equipment 17 via
remote access link 19. The one or more access communications may
indicate one or more user profiles or favorites information. At
step 1925, the remote program guide obtains program guide data
according to the preference profiles.
[0130] At step 1930, remote program guide access device 24 may
provide the user with the opportunity to remotely navigate through
favorites. Remote program guide access device 24 may, for example,
have obtained program listings information (step 1600, FIG. 15),
sorted the information according to the favorites information, and
displayed only listings for a favorite channel or theme.
Alternatively, remote program guide access device 24 may, for
example, display television program listings in a grid, table, or
list while highlighting favorite channels. A user may be provided
with the opportunity to "jump" between favorite listings or
channels by issuing an appropriate command using user interface
52.
[0131] FIG. 19 shows illustrative steps involved in providing a
user with remote access to program recording. At step 2000, the
remote access program guide provides the user with the opportunity
to select a program for recording. This opportunity may be provided
in response to the user indicating a desire to record programming
by, for example, selecting a program listing (step 1640, FIG. 15)
and issuing a suitable command. In response, the remote access
program guide remotely schedules the program for recording with the
local interactive television program guide implemented on
interactive television program guide equipment 17 (step 2000).
Remote program guide access device 24 may exchange, for example,
one or more access communications with interactive television
program guide equipment 17 that are sent over remote access link
19.
[0132] At an appropriate time, the program is recorded (step 2020).
As indicated by substeps 2030 and 2040, the program may be recorded
by the local interactive program guide on interactive television
program guide equipment 17 (e.g., digital storage device 31 or
secondary storage device 32 of user television equipment 22 (FIG.
3), or on program guide server 25, or may be recorded by remote
program guide access device 24 on storage 56 (FIG. 5) or program
guide server 25. If the program is recorded by remote program guide
access device 24, the programming may, for example, be digitized
and transmitted as a MPEG-2 data stream over remote access link 19
using access communications.
[0133] FIG. 20 shows illustrative steps involved in providing the
user with remote access to remotely order pay-per-view programs and
packages using the local interactive television program guide
implemented on interactive television program guide equipment 17.
At step 2100, the remote access program guide obtains pay-per-view
information (e.g., price, ordering information, time, event code,
selections in a package, etc.), from the interactive program guide
implemented on interactive television program guide equipment 17
via remote access link 19. The pay-per-view information may be
obtained on startup, periodically, continuously, on demand in
response to a suitable user command, or using any other suitable
scheme. The pay-per-view information is provided to the user by the
remote access program guide using user interface 52 of remote
program guide access device 24 in any suitable fashion (step
2110).
[0134] At step 2120, the remote access program guide provides the
user with the opportunity to remotely order a pay-per-view program
or package. This opportunity may be provided, for example, in
response to the user selecting a pay-per-view program listing or
package listing (e.g., step 1640, FIG. 15). At step 2130, the
remote access program guide remotely orders the pay-per-view
program or package by indicating the program or package to the
local interactive television program guide by, for example,
exchanging one or more access communications over remote access
link 19 (step 2133). The access communications may contain the
pay-per-view information for the selected pay-per-view program or
package. The local guide may order the program or package at step
2135. Alternately, the remote access program guide may order the
pay-per-view program (step 2137).
[0135] The way in which the remote access program guide orders the
pay-per-view program using the local interactive television program
guide may depend on the configuration of the system. If the system
is configured as shown in FIGS. 2a and 2c, the remote access
program guide may, for example, provide the pay-per-view
information to the interactive television program guide implemented
at least partially on user television equipment 22. The interactive
television program guide may, in turn, order the pay-per-view
program with television distribution facility 16. If the system is
configured as shown in FIGS. 2b and 2d, the remote access program
guide may, for example, provide the pay-per-view information to the
interactive television program guide via separate communications
device 27. If the system is configured as shown in FIGS. 6a and 6b,
the remote access program guide may provide the pay-per-view
information via Internet service system 61.
[0136] FIG. 21 shows illustrative steps involved in providing a
user with access to remotely-played video or audio. At step 2200,
the remote access program guide may obtain video or audio
information from the interactive television program guide
implemented on interactive television program guide equipment 17
via remote access link 19. This may occur, for example, in response
to the user selecting a video or audio listing displayed by remote
program guide access device 24.
[0137] Substeps 2210 and 2220 show illustrative steps involved in
obtaining directory information used in providing a user with audio
and video information. The remote access program guide may query
the local interactive television program guide implemented on
interactive television program guide equipment 17 for directory
information using one or more access communications that are sent
over remote access link 19 (step 2210). The directory information
may be contained, for example, in a media library directory for a
media library that is stored on user television equipment 22, or by
television distribution facility 16. The directory information may
be provided back to the remote access program guide by exchanging
one or more remote access communications between interactive
television program guide equipment 17 and remote program guide
access device 24 over remote access link 19, as is indicated by
substep 2220. Step 2210 may be skipped and step 2220 performed
when, for example, directory information or listings are provided
to the remote access guide ahead of time.
[0138] At step 2230, the remote access program guide may provide
the user with the opportunity to select a video or audio for remote
playing. The user may select a video or audio by, for example,
selecting a listing that is indicated to the user by user interface
52. The user may be provided with an opportunity to play a program
in real-time via the local and remote guides, or to play a stored
program. In response, the remote access program guide may obtain
the selected video or audio from the local interactive television
program guide using access communications that are sent over remote
access link 19. The access communications may contain the video or
audio in a suitable analog or digital format. At step 2250, remote
program guide access device 24 remotely plays the video or audio
for the user using user interface 52. Selected video may be
displayed, for example, on a suitable monitor, LCD, or other
suitable display device. Selected audio may be played for the user
using any suitable speaker. Audio may, for example, be played by a
car stereo if remote program guide access device 24 is an
automobile PC.
[0139] FIG. 22 shows illustrative steps involved in providing the
user with the opportunity to remotely poll the local interactive
television program guide implemented on interactive television
program guide equipment 17. At step 2300, the remote access program
guide may poll the interactive television program guide for polling
information. The polling information may indicate, for example,
whether user television equipment 22 is in use, the current channel
user television equipment 22 is tuned to, the current programming
rating, current program title, the status of remote access link 19
or communications paths 20, the available devices of user
television equipment 22, or any other status related
information.
[0140] Step 2300 may include substeps 2310 and 2320 for obtaining
the polling information. At substep 2310, remote program guide
access device 24 may obtain the polling information. Polling
information may be obtained on startup, periodically, continuously,
on demand in response to a suitable user command, or using any
other suitable scheme. More particularly, status information may be
obtained using SNMP (substep 2320), if desired. If SNMP is used to
obtain polling information, for example, the access communications
may include commands and protocol data units (PDUs). Other suitable
network management protocols may also be used. At step 2330, remote
program guide access device 24 may present the polling information
to the user in any suitable method. The polling information may be
displayed, for example, in a status display screen such as status
display screen 200 of FIG. 11. Polling information may, for
example, be output to the user via synthesized voice outputs that
are played using a speaker and voice synthesis hardware and
software.
[0141] FIG. 23 shows illustrative steps involved in providing the
user with the opportunity to create messages and send them between
the local interactive television program guide implemented on
interactive television program guide equipment 17 and the remote
access program guide. At step 2400, the user is provided with the
opportunity to create a message. The user may create the message
with the local interactive television program guide using, for
example, user interface 46 of user television equipment 22 (FIG.
4), or the user may create the message using user interface 52 of
remote program guide access device 24.
[0142] The message may include any suitable text, graphics, or
audio. The user may, for example, speak an audio message into a
microphone. The audio message may be digitized and stored in an
access communication for transfer over remote access link 19.
Alternatively, the user may input a text message using a suitable
text input device (e.g., a keyboard). However the message is
created and whatever its content, the message is transferred over
remote access link 19 using one or more access communications. The
message may be transferred from the interactive television program
guide to the remote access program guide, or from the remote access
program guide to the local interactive television program guide,
depending on where the message was created and its intended
destination. At step 2410, the message may be presented to the user
by user television equipment 22 (e.g., substep 2430), or by remote
program guide access device 24 (e.g., substep 2440).
[0143] The discussion thus far has focused on implementing the
invention with an interactive television program guide. The
invention may also be applied to non-program-guide interactive
television applications. Local non-program-guide applications run
on user television equipment such as a set-top box and
corresponding remote access non-program-guide application may run
on a remote access device. Interactive television applications may
be stand-alone applications, portions of an operating system, or
any suitable combination thereof.
[0144] One non-program-guide application that may be implemented on
a set-top box in accordance with the present invention is an
Internet browser. An Internet browser may have settings such as
bookmarks, parental control settings, and general preferences that
control how the browser functions. As shown in FIG. 24, a remote
access device may provide the user with access to a browser
application by displaying, for example, browser screen 700 of a
remote access browser application. Browser screen 799 may have a
bookmark option 705. A user may, for example, select bookmark
option 705 and add a bookmark (i.e., a record of the address of the
current web site that can be used to access the site). After the
user adds a bookmark with a remote access Internet browser, the
remote access Internet browser may exchange one or more access
communications with a local Internet browser to add the bookmark to
the local browser.
[0145] Another application that may be implemented or a set-top box
in accordance with the present invention is a shopping application.
A shopping application may have settings such as a default shipping
address and credit card number. As shown in FIG. 25, a remote
access shopping application screen 730 may have settings such as a
shipping address 720, and credit card number 725. A user may, for
example, add a shipping address and credit card information. After
a user adds shipping and credit card information with the remote
access shopping application, the remote access application may
exchange one or more access communications with a local shopping
application to provide the information to the local
application.
[0146] Another non-program-guide application that may be
implemented on a set-top box and accessed via a remote access
device in accordance with the present invention is a stock ticker.
A stock ticker may have settings such as settings indicating the
top ten stocks in which the user is interested. As shown in FIG.
26, a remote access device may display a remote access stock ticker
settings screen 710. Stock ticker settings screen 710 may have, for
example, ticker symbol 712 and a top ten stocks option 715. A user
may, for example, add a top stock. By exchanging one or more access
communications, the remote access stock ticker application can make
the top ten stock settings effective on a local stock ticker
application.
[0147] A chat application may be implemented on a set top box. Chat
applications are services that allow users to exchange chat
messages with other users in real time. A chat application may be
implemented as a stand-alone chat application or as part of another
application such as a program guide application. Chat applications
that may be implemented on user television equipment are described
in DeWeese et al. U.S. patent application Ser. No. 09/356,270,
filed Jul. 16, 1999, which is hereby incorporated by reference
herein in its entirety. A user may remotely adjust settings
associated with a chat application such as the size of a chat
window, an address book, or whether to filter potentially offensive
messages. After the user adjusts chat settings with a remote access
chat application running on a remote access device, the remote
access chat application may remotely adjust the settings of a local
chat application by, for example, exchanging one or more access
communications with the local chat application over a remote access
link.
[0148] If desired, the settings of an e-mail application running on
a set-top box may be adjusted remotely. Set-top based messaging
systems are described, for example, in concurrently filed McKissick
et al. U.S. patent application Ser. No. 09/356,245, filed Jul. 16,
1999, which is hereby incorporated by reference herein in its
entirety. Users may, for example, remotely add to or change an
address book. When the user adjusts e-mail settings with a remote
access e-mail application running on a remote access device, the
remote access e-mail application may remotely adjust the settings
of a local e-mail application by, for example, exchanging one or
more access communications with the local e-mail application over a
remote access link.
[0149] The foregoing is merely illustrative of the principles of
this invention and various modifications can be made by those
skilled in the art without departing from the scope and spirit of
the invention.
