SYSTEMS AND METHODS FOR INTERACTIVE PROGRAM GUIDES WITH PERSONAL VIDEO RECORDING FEATURES

Background of the Invention

The present invention relates to interactive television program guide (IPG) systems and personal video recording (PVR) systems, and more particularly to enhanced PVR-IPG features.

⁰ Interactive television systems such as interactive television program guide systems are now widely available to the general public. Interactive television program guide systems may be used to provide

CA 02438947 2009-04-20

61009-643 interactive television services such as services for allowing a user to tune to a program, to set parental locks, to record a program, to set reminders, etc. Interactive program guide systems are illustratively described, for example, in Knee et al. U.S. Patent No.

5,589,892, and Knudson et al. U.S. Patent Application No. 09/357,941, filed July 16, 1999.

In recent years, PVRs such as those provided by companies such as Tivo and ReplayTV have become available. Such systems and devices may be used to provide interactive television services such as services for recording television programs onto a digital medium, such as a hard disk. In one known system, a PVR may use an MPEG encoder to digitize broadcast television and then store the digitized broadcast television for later retrieval on a hard disk drive. In such systems, a digitized broadcast may be converted to an analog NTSC signal for display on a television.

In conventional PVRs, a program buffer is typically used to allow users to pause, rewind, or playback a television broadcast that a user is watching.

A PVR buffer is typically a circular buffer that stores the most recent n minutes of programming that was watched by a user. One drawback of this buffering technique is that the buffer only allows the user to pause or rewind up to the last n minutes and only on the currently tuned channel since it was most recently tuned.

Conventional PVR systems may also provide other features such as features for allowing users to select to record television content. In such systems, a live program is typically recorded from the point at which a

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 user requests the program to be recorded. One drawback of such systems is that portions of the live program that were previously buffered are typically ignored.

In such systems, interactive television services are typically provided to users through the presentation of graphics. One drawback of such systems is that the presentation of the graphics may undesirably cause a user to miss live television content that the user is watching.

Another drawback of known PVR systems is that such systems do not typically support pay-per-view television programming. Pay-per-view (PPV) television programs are now widely available through cable television service providers, but are not typically supported by PVRs for scheduling recordings or providing other types of PVR-related functionality.

Improvements to these IPG and/or PVR systems are desirable to alleviate these and other drawbacks and to simplify the use of such systems while providing additional functionality to television viewers. Accordingly, new systems and methods for interactive program guides with personal video recording functions are provided.

Summary of the Invention

In accordance with the principles of the present invention, an interactive television application may be implemented on a television system to provide enhanced PVR-related functionality.

An interactive television application may be implemented to integrate PVR and set-top box program guide features, functionality, and information. For example, an interactive television application may be

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 implemented to provide PVR features, functionality, and information in an interactive television program guide such as an interactive television program guide running on a cable set-top box. Other configurations for integrating such features may also be used.

An interactive television application may display a main menu display screen that may include options such as a program listings option, a video-ondemand option, a pay-per-view (PPV) option, or a current weather option to provide interactive services. The main menu display screen may include PVR-related options such as a recordings option, a scheduled recordings option, and a delete priority option.

A recordings display screen may be displayed when the user selects the recordings option. The recordings display screen may include a list of recordings that are available from a PVR. The programs that are included in the list of recordings may be programs that were manually or automatically recorded by the PVR. The listings in the display screen may be selectable to allow a user to access information and/or options that are related to a selected listing. Other techniques for accessing the list of recordings may also be provided.

A scheduled recordings display screen may be displayed when a user selects a scheduled recordings option from a main menu display screen. Other techniques for accessing a scheduled recordings display screen may also be used. The scheduled recordings display screen may include a list of programs that are scheduled to be recorded (e.g., scheduled to be recorded by a PVR). Programs on the list may have been scheduled to be recorded automatically or manually. Programs that are

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 5 automatically scheduled to be recorded or that are automatically recorded may be programs that an interactive television application selects for recording based on some criteria such as user preferences.

Programs that are manually recorded or manually scheduled to be recorded may be programs that a user specifically selected to be recorded. Series recordings that are selected for recording by a user may also be considered to be manual recordings. Listings in a scheduled recordings display screen may be selectable to allow a user to access information and/or options that are related to a selected program listing. Information about series recordings may be accessed through a scheduled recordings display screen.

An interactive television application may allow a user to schedule and cancel one-time and/or series recordings from a program listings screen, a browse overlay, a flip overlay, a video of a program that is being watched, an advertisement, or any other suitable location. A series recording may be used to schedule and record a series of episodes in a particular program series. The user may be provided with an opportunity to configure series recordings based on episode type (e.g. first-run, repeat, etc.) and/or channels.

The interactive television application may provide a user with an opportunity to configure a recording buffer around a program that is scheduled to be recorded. The record quality of a recording may also be selected by a user. An interactive television application may allow a user to schedule a recording from practically any point in a program guide. For example, a recording may be scheduled from a program listing bar, a program information display screen, an advertisement

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 6 display screen, or any other suitable point in a program guide.

The interactive television application may provide a user with the ability to record PPV programs and to schedule PPV programs to be recorded. An interactive television application may automatically order a PPV program that a user schedules to be recorded. A user may be prompted to purchase a PPV program when the user schedules a PPV program to be recorded. Recording configuration settings for a PPV program, such as recording quality and recording buffer time, may be selected by a user.

The interactive television application may provide VCR type functions for watching a recorded program including pause, fast-forward, rewind, stop, play, record, and other suitable functions. When pausing live content, the interactive television application may display paused video of the television content and display a timer showing how far back the paused video is behind live content. Program flow control options such as a play option, a rewind option, a fast-forward option, and a record option may also be displayed.

If desired, television programming may be recorded without including graphics such as interactive television application display screens and overlays as part of the recordings. If desired, television programming may be recorded without including in the recording changes in volume settings that a user selects during the recording.

An interactive television application may display different PVR related overlays at appropriate points in interactions with a user. For example, an overlay may be displayed when a recording is canceled,

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 when a program starts to be recorded, when a recording is completed, or when other events occur. A user may be permitted to cancel a recording that is under way. For example, the user may cancel the recording by pressing a remote control record button or by pressing a remote control button to change the current channel. If desired, a user may not be permitted to change the current channel unless the user affirmatively confirms the cancellation of the recording.

The interactive television application may provide a user with a reminder that a scheduled recording is about to start. A reminder may be displayed at a preset time before the start of a scheduled recording.

The reminder may include the title of the program that is scheduled to be recorded. A user may be provided with an opportunity to confirm that the program should be recorded, for example, by selecting a particular item in the reminder overlay.

The interactive television application may provide a user with the ability to set delete priority settings for recordings. The user may set delete priority settings for a specific program. The user may be allowed to set general delete priority settings. The interactive television application may provide userselectable options for editing the order in which individual recordings will be deleted. A delete priority order may be set for recordings in general based on program type or broadcast type. A delete priority order may be set between series recordings. Options may also be available for deleting recordings after a specified period of time and after the program has been viewed.

An interactive television application may be implemented to provide multiple program guides with

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 respect to PVR information and features. Each program guide may correspond to a different user in a household. Information related to a specific user may be displayed and/or updated when the program guide corresponding to that user is accessed. The program guides may be configured to interact differently with different users. The list of recordings and/or list of scheduled recordings for one user may not be available to other users in their program guides. To identify a current user, the interactive television application may require users to log into their program guides. If desired, users may be required to login when they seek to access PVR related features and/or information. Different users may use their program guides to select different programs to be recorded. A PVR may record programs based on the user selections. Recordings may be performed independent of which user is currently logged into the system. Users may be permitted to delete recordings from their list of recordings. The interactive television application may delete information related to a recording that a user selects to delete. Deleting information related to a recording may remove the recording from that user's list of recordings. The interactive television application may delete a program from a PVR based on user selections. If a particular recording is associated with more than one user, the interactive television application may delete the recording when all of the users associated with that recording have selected that program to be deleted.

PVR users may be notified of changes that are to be made to the recording content in a storage device.

A notification may be sent to inform a user that a particular program is about to be recorded or deleted.

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

In a multiple program guide environment, notifications may be sent to users to which the upcoming change pertains. The notification may provide the user with an opportunity to confirm or cancel the change that is to be made. The notification may be sent via a program guide overlay, using e-mail, or using other suitable techniques. A notification may notify a user that a particular program that was earlier selected by the user to be recorded is about to be recorded. A notification may notify a user that a particular program, which was automatically selected to be recorded (e.g., based on user preferences), is about to be recorded. A notification may notify a user that a particular program is about to be deleted based on user-selected delete priority settings. A notification may notify a user that a particular program is about to be recorded based on automatic delete settings.

An interactive television application may maintain a global list of programs that are presently stored on a PVR. The list may contain all programs that have been recorded. The list may contain programs that were deleted (automatically or manually), but are still available from the storage medium of the PVR. For example, in one instance, the deletion of a recording may only delete particular information about that recording without actually deleting the video of the recording from the PVR.

In order to not re-record a program, an interactive television application may check a global list of programs to determine whether a program that has been selected to be recorded is already available from the PVR. The interactive television application may not record a program if that program is currently on the

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 global list. The currently stored program on the PVR may be used for the selected recording. If desired, a user may be provided with an opportunity to edit the global list. A user may be permitted to permanently delete a program from the global list.

Stored video advertisements may be presented to users using a storage device such as a PVR. Video advertisements may be presented using full screen video or scaled video. A video advertisement may be presented when a user is interacting with a program guide. Scaled video for an advertisement may be presented in a program guide display screen. Full screen video of the advertisement may be presented when a user selects the scaled video in a program guide display screen. A stored video advertisement may be displayed when a user enters a program guide (e.g., a user selects a guide button of a remote control while watching live television). A stored video advertisement may be linked to a live video advertisement that is being presented to a user. The stored video advertisement may be presented after the presentation of the live video. The stored video advertisement may be presented based on user preferences or other criteria. Current television content may be paused for a user when the stored video advertisement is displayed. The stored video advertisement may be used replace a live television advertisement.

A storage device such as a PVR may be used to buffer television content to provide a user with an opportunity to control the flow of current television content and to take other actions. A straight buffer may be created when a user tunes a new channel or program.

The straight buffer may be used to buffer the currently tuned program. If desired, a buffer size may be

CA 02438947 2003-08-20

02/069636

PCT/US02/08043 allocated to the buffer that is suitable for holding the remainder of the current program. Each time a user changes to viewing a new program, the interactive television application may create a new buffer. Space for a buffer may be allocated by allocating free space that is available on a storage device, by deleting an existing buffer (e.g., the oldest existing buffer), or by deleting a portion of an existing buffer (e.g., the oldest portion of the oldest buffer). If desired, the size of a buffer may be incrementally increased as needed.

In the situation where a user tunes away and returns to a particular program, a buffer that was created for that program may combine video that was buffered before the user tuned away and video buffered when the user returned to watching that program. The separate portion of the program before and after the user tuned away may be combined by concatenating the two portions, by inserting blank video between the two portions, by inserting text or other content between the two portions, or by using combinations thereof. If desired, content that is inserted between the two portions may have a duration that corresponds to the length of the break between the portions. In a multituner environment, the buffer for a program may contain the portions of the video that the user may have missed by tuning away. Multiple tuners may be implemented to permit the PVR to buffer different programs in parallel. Multiple tuners may also be used to record one program while watching another program or to record two or more programs at the same time.

A user may be allowed to control program flow using a buffer. A user may be permitted to rewind a

CA 02438947 2003-08-20

WO 02/069636

PCT/US02/08043 program that is playing from a program buffer. Rewinding a current program to the top of that program may allow the user to skip to a previous program by selecting to rewind again. Using fast-forward to reach the end of a program may cause the program to stop playing or may cause the next program from the buffer to be played.

The buffer for a current program may be used as part of a recording when the user selects to record that program. A program that is being buffered may be recorded by recording currently airing video of the program and saving previous portions of the program that are buffered. An interactive television application may retain buffers for programs that have ended. A user may be permitted to view a list of programs that are currently stored in program buffers. An interactive television application may save a buffer for a program as a recording when a user selects that program to be recorded. The selection may be made even after the program has ended.

Storage space in a storage device may be assigned automatically or manually to buffer programming. An interactive television application may automatically assign all or a portion of the storage space in a storage device to buffer programming. If desired, a user may be provided with an opportunity to set the total size to be used for buffering, set the total number of buffers that can be active at one time, set the size of each buffer, and set how often buffers should be deleted.

An interactive television application may automatically pause television content that a user is watching when the user interacts with the interactive television application. A current television program or commercial that a user is watching may be paused when a

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 13 program guide display screen or a stored video advertisement is displayed. The television content may remain paused while the user interacts with the interactive television application or watches the stored video advertisement. The display of the television content may resume when the user exits the interactive television application. The display of the television content may resume from the point at which it was paused. If desired, the interactive television application may provide the user with an opportunity to select whether the television content should be resumed from the point at which it was automatically paused or resumed from its current point.

Other PVR related features may also be provided. An interactive television application may display a scheduled recording icon that changes based on the status of a scheduled recording. The interactive television application may provide the user with the ability to create keyword-based recordings. The interactive television application may provide the user with the ability to set the recording priority for a program. The recording priority settings may, for example, include a can't miss priority, an if possible priority, a desired priority, an if space available priority, or any other suitable recording priority. Providing a user with three or more different recording priority levels to chose from allows a user greater flexibility in configuring his or her recording preferences. An interactive television application may display recorded programs within a browse overlay, a program listings display screen, or within other listing screens. Recorded programs may be listed amongst regularly scheduled programs.

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

The interactive television application may indicate how much memory is available on the PVR, and specifically how much memory is available at each recording priority level and when memory will run out based on the current recording settings.

Playback controls may be used to fast-forward and rewind a program at different speeds. The range of different speeds may include a range from different slow motion speeds to different fast-forward speeds. The interactive television application may provide the user with the ability to schedule VOD programs for recordings. The interactive television application may propose a selection of times at which the VOD program may be recorded. The interactive television application may propose a time for recording a VOD program based on currently scheduled recordings and reminders to avoid conflicts in recordings. If a VOD or PPV program is marked as copy-protected, the interactive television application may restrict whether a user can schedule a recording for the copyrighted program.

VOD and PPV programs may be priced to have different prices depending on the usage. For example, one price may be for watching a program, another price may be for recording a program, and a third price may be for each playback of a recording. The interactive television application may also support pay-per-recording and pay-per-playback of ordinary content. The interactive television application may also support a system in which the user pays for recording space by the amount of storage space used on a remote server (e.g., pay for the amount of storage in a remote server that stores personal video of a user).

- 15 An interactive television application may be implemented to push television advertisements and other content, to be locally stored and displayed.

An interactive television application may allow a user to set a manual recording by specifying the time, date, channel, and duration for recording. When the interactive television application identifies data matching the manual recording, the manual recording may be converted to a programbased recording (a one-time recording).

The interactive television application may provide the use with the ability to edit recorded programs. Editing features may include, removing sections from a recording, removing commercials from a recording, combining recorded programs, creating playlists of recordings, marking locations . in recorded programs for quick reference, or other suitable editing features.

Main facility 102 may distribute the

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 29 program guide information to distribution facility 110 via communications path 108.

Communications path 108 may be any suitable communications path, such as a satellite link, a cable link, a fiber-optic link, a microwave link, a telephone network link, an Internet link, or a combination of such links. If it is desired to transmit video signals (e.g., television programs) over communications path 108 in addition to data signals, a relatively high bandwidth link such as a satellite link may be preferable to a relatively low bandwidth link such as a telephone line. Only one distribution facility 110 is shown in FIG. 1 to avoid over-complicating the drawing. Multiple distribution facilities may be involved in implementing interactive services.

The program guide information or content transmitted by main facility 102 to distribution facility 110 may include television program listings data (such as program times, channels, titles, descriptions, program type, genre, actors) or any other suitable data.

The promotional information transmitted by main facility 102 to distribution facility 110 may include various promotional banners, promotional ads, promotional slogans, promotional advertisements, or any other suitable promotional material.

138 next time a user accesses this option for the selected recording. If desired, the user may be given the opportunity to name or number the individual markers within a program, and to jump to a marker by name or number. If desired, keys on the remote control (such as page up and page down) may be used to quickly navigate to markers while watching a recording without having to display an overlay. Markers may be maintained when recordings are combined, when parts of a recording are removed, and when a playlist is created.

An interactive television application may be implemented to provide a PVR with multiple user accounts. FIG. 66 shows illustrative steps involved in providing multiple program guides for PVR users in a household.

With reference now to FIG. 66, at step 3902, user equipment that includes a PVR may be provided in a household. If desired, some of the functionality may be provided using equipment that is not in the user's home. For example, programs may be recorded to a server in a distribution facility. At step 3904, an interactive television application may be implemented on the user equipment to provide multiple program guides. Each program guide may correspond to one of the household members .

At step 3906, an interactive television application may associate different household member specific PVR information with different household members. The member specific PVR information of each household member may be associated with that user's program guide. PVR information may include configuration settings for recordings, user preference information, scheduled recordings information, recording information or other PVR related information. If desired, steps 3904

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 139 and 3906 may be combined. If desired, the size of the storage space to be used for configuration settings, user preferences, program information, buffers, stored programs, and other user-specific data may be specified for the multiple program guides. Alternatively, storage space may not be pre-allocated, and memory may be allocated from available memory as each user needs it.

At step 3908, an interactive television application may allow household members to interact with respect to the PVR and/or with respect to their PVR information using their corresponding program guides. For example, a household member may use his or her program guide to record a program on a PVR, to schedule a PVR to perform a recording, or to view or manipulate his or her list of PVR recordings .

Step 3908 may include step 3910. At step 3910, the interactive television application may display PVR information that is associated with a particular household member when that household member uses their corresponding program guide. At step 3912, the interactive television application may cause the PVR to record or delete programs based on the PVR information that is associated with the household members. The PVR information may be updated when a program is recorded or deleted. Thus, the interactive television application may provide a unique program guide for each member of a household.

A household member may begin to use his or her program guide by logging into his or her program guide. For example, with reference now to FIG. 67, the interactive television application may display user-login display screen 4002. User-login display screen 4002 may include options 4004 for allowing users to select their

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

140 login identification. User-login display screen 4002 may also include data entry area 4006. Area 4006 may be used to enter a personal identification code that is associated with a login identification. Once a user has logged in to access one feature, the user may not be required to login to access additional features. For example, there may be a change user or login button on the main menu screen or a key on the remote control.

If desired, a user may be automatically logged out after a period of inactivity, or when the system is turned off.

Personalized main menu display screen 4008 may be displayed when a user selects a particular login identification using options 4004 and enters a valid personal identification code. Main menu display screen 4008 may include text 4014 identifying the current user and may include options for providing interactive services. For example, main menu display screen 4008 may include recordings option 4010 and scheduled recordings option 4012 that the user may select to access PVR related information and features. User preferences and PVR setup options accessed from this main menu screen may be specific to the logged in user.

A user may access his or her list of scheduled recordings when that user logs into their program guide. For example, with reference now to FIG. 68, user-login display screen 4102 may be displayed to provide users with an opportunity to login. In this instance, display screen 4102 identifies the users to be Tom and Jerry.

Scheduled recordings display screen 4104 may be displayed after a user logs into their program guide and selects to access his or her list of scheduled recordings. As mentioned above, a user may log in by selecting a user login and entering a personal

CA 02438947 2003-08-20

WO 02/069636

PCT/US02/08043

141 identification code. Scheduled recordings display screen 4104 may include list 4106 containing listings for programs that Jerry selected to be recorded. Tom's list of scheduled recordings may be displayed in scheduled recordings display screen 4108 upon user request after Tom logs in to his program guide. Scheduled recordings display screen 4108 may include list 4110 containing listings for programs that Tom selected to be recorded.

An interactive television application may associate different programs to be recorded with different users. For example, as shown, list 4110 that is displayed for Tom is different from list 4106 that is displayed for Jerry.

If desired, a user may be required to login when the user selects to access PVR related information and/or features. For example, with reference now to FIG. 69, main menu display screen 4202 may be displayed for example when a user presses a main menu remote control button. Access to main menu display screen 4202 may be provided without requiring user login. From main menu display screen 4202, a user may be permitted to access general program guide features such as program listings, weather information, etc.

Main menu display screen 4202 may contain recordings option 4204 and scheduled recordings option 4206. User-login display screen 4208 may be displayed when a user selects scheduled recordings option 4206 in main menu display screen 4202. If desired, user-login display screen 4208 may be presented as an overlay. User-login display screen 4208 may contain login identification options 4210 and data entry area 4212.

142 Personalized scheduled recordings display screen 4214 may be displayed when a particular user, in this case, Jerry logs into his program guide. Scheduled recordings display screen 4214 may contain list 4216 for Jerry's scheduled recordings list for January· 18, 2002, and list 4218 for Jerry's scheduled recordings for January 20, 2002. Scheduled recordings display screen 4212 may contain interactive advertisement 4220. Examples of interactive television program guide systems with interactive advertisements are illustratively shown in Knudson, et al, which is mentioned below.

Features for managing recordings may be implemented in a similar way. For example, with reference now to FIG. 70, main menu display screen 4302 may be displayed for example when a user presses a remote control menu button. Main menu display screen 4302 may contain recordings option 4304. User-login display screen 4307 may be displayed when a user selects recordings option 4304. At user-login display screen 4306, a user may use options 4308 to select their login identification and may enter their personal identification code using data entry area 4310. Personalized recorded programs display screen 4312 may be displayed when a user, in this case Calvin, logs into the system using display screen 4307. Recorded programs display screen 4312 may contain list 4314 that lists programs that have been recorded for Calvin.

Illustrative steps involved in recording programs in a multiple program guide environment are shown in FIG. 71. With reference now to FIG. 71, at step 4402, a user may be provided with an opportunity to log into his/her program guide. Multiple program guides may be provided that each correspond to a different user.

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

143 The multiple program guides may be implemented to be available through local user equipment (e.g., user equipment used by members in a household) and may also be implemented using remote equipment, such as a remote server. The user equipment or server may include a storage device such as a PVR. A user may be permitted to log into their program guide to interact with respect to the storage device. At step 4404, a user who is currently logged into their program guide may be permitted to select programs to be recorded on the storage device (e.g., on a local recording device or on the server). At step 4406, the user equipment may record programs based on which programs were selected to be recorded by the users while they were in their program guides. The interactive television application that provides the multiple program guides may record programs based on the user-selections irrespective of which user is currently logged into their program. Therefore, a program may be recorded for one user when a program guide for another is in use. Step 4406 may include updating user-specific information regarding recordings so that the new information may be reflected when a user logs into the system. If multiple users select to record the same program, the system may only record one copy.

Different techniques may be implemented to allow users in a multiple program guide environment to select programs to be recorded. For example, with reference now to FIG. 72, program listings display screen 4502 may be displayed when a particular user logs into their program guide and selects to access program listings. If desired, program listings display screen 4502 may contain text identifying the current user, which in this case is Jerry. Display screen 4502 may contain

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

144 program listings 4510. The current user may be permitted to select a program to be recorded by moving highlight window 4504 over a program listing such as the listing for program A and pressing a remote control record key. Icon 4506 may be displayed in association with program A when the user has selected to record program A. Thus, icon 4506 indicates that Jerry has selected to record program A, and program A is part of his list of scheduled recordings .

Another technique for selecting a program to be recorded may involve requesting user identification when a recording related action is sought to be taken by a current user. For example, with reference now to FIG.

73, program information display screen 4602 may be displayed when a user selects to obtain information on a particular program. A user may be permitted to access information display screen 4602 without having to log into their program guide. Information display screen 4602 may contain record option 4604 that a user may select to have the current program recorded (e.g., recorded using a PVR). Overlay 4606 may be displayed when the current user selects record option 4604.

Overlay 4606 may include identification option 4608 that the user may scroll to select their login identification, may include data entry area 4610 that may be used to enter a personal identification number (PIN), OK option 4618 that may be used to log in, and cancel option 4616 that may be selected to cancel overlay 4606. Icon 4612 may be displayed in information display screen 4602 when the current user enters the appropriate information in overlay 4606. Icon 4612 may indicate that the program is now selected to be recorded. Information display screen 4602 may now contain cancel recording option 4614 that

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

145 the user may select to cancel the scheduled recording.

The cancellation of the recording may require that the user select a login identification and enter a PIN again.

In a multiple program guide environment, recordings may be manually deleted by individual users. Illustrative steps involved in deleting recordings are shown in FIG. 74. With reference now to FIG. 74, at step 4702, an interactive television application may associate a recording with one or more users. More than one user may be associated with a particular recording when more than one user selects the same program to be recorded from within their guides. At step 4704, users who are associated with the recording may be provided with an opportunity to delete the recording when they are in their program guide. At step 4706, the recording may be deleted when all of the users that are associated with that recording have selected to delete the recording.

Step 4706 may include step 4708. At step 4708, information that associates a recording with a user may be deleted when the user selects to delete the recording. Step 4708 may be used to remove the association of that user with the program that the user selected to delete (e.g., removes the program name for the recording from the user's list of recordings). Information on the program may be deleted without actually deleting the recording itself, e.g., if other users have selected the program for recording.

FIGS. 75 and 76 show an illustrative sequence of display screens that may be provided based on the illustrative steps shown in FIG. 74. With reference now to FIG. 75, login display screen 4802 may be displayed when a user seeks to login to their program guide. If desired, login display screen 4802 may be an overlay. In

- 146 this example, there are two users that are identified in display screen 4802 as Tom and Jerry. Recordings display screen 4804 for Jerry's recordings may be displayed when Jerry logs into his program guide using login display screen 4802 and selects to access his list of recordings. Recordings display screen 4810 for Tom's recordings may be displayed when Tom logs into his program guide using login display screen 4802 and selects to access his list of recordings. As shown, the recordings contained in list 4806 in display screen 4804 for Jerry and in list 4812 in display screen 4810 for Tom are different except for one program. The program Living in Peace is listed in both lists 4806 and 4812.

Information display screen 4814 that contains information and options for the program Living in Peace may be displayed when Jerry moves highlight window 4808 in recordings display screen 4804 over the listing for the program Living in Peace and presses a remote control OK key. Information display screen 4814 may include delete option 4816. The program guide may allow Jerry to select delete option 4816 and to subsequently return to his updated list of programs, which are displayed in recordings display screen 4818. As shown, a listing for the program Living in Peace is no longer included in list 4806 of Jerry's recordings. Recordings display screen 4820 for Tom's recordings may be displayed after the program Living in Peace is selected to be deleted by Jerry. Recordings display screen 4820 may include list 4812 of Tom's recordings, which still contains listing 4822 for the program Living in Peace. Thus, one user may delete a recording of a program from his or her guide without changing the program guides of the other users.

Recording display screen 4920 for Tom’s recordings may include listing 4926 for the program Living in Peace. Information display screen 4928 containing information and options for the program Living in Peace may be displayed when the current user (Tom) selects listing 4926. Information display screen 4928 may include delete option 4930. A recording of the program Living in Peace and/or information related to that program may be deleted when delete option 4930 is selected. After delete option 4930 is selected for the program Living in Peace, the interactive television application may display recordings display screen 4932 that shows that the deleted program is no longer on Tom's list of recordings.

The interactive television application may include features for handling differences between recording settings that two different users have selected for recording the same program. The interactive television application may record the program to based on both settings (e.g., using the highest setting that is set by each user). For example, if the two users select different before/after buffer times, the application may use the longer of the two. If the two users select different record qualities, the application may select the highest quality. If two users select different record priorities, the application may use the highest specified priority.

- 148 Accordingly, multiple program guides may be provided that correspond to different users that share the same user equipment.

A notification feature may be another feature that may be provided with respect to recording activity. Illustrative steps involved in providing notifications for upcoming changes in recording content are shown in FIG. 77. At step 5002, an interactive television application may provide a user with an opportunity to select a program to be recorded. At step 5004, a user may be provided with an opportunity to select delete priority settings for a particular recording.

At step 5006, an interactive television application may automatically select a program to be recorded or deleted. A particular program may be automatically selected to be recorded based on stored user preferences or other suitable criteria. A recording may be deleted automatically for example when the recording is one that was created over a certain number of days ago or when the recording has not been viewed in a given period.

At step 5008, a notification may be sent that describes a change that is to be made to the recorded content. For example, the notification may state that a particular program is about to be recorded or deleted.

The change that is to be made may be determined based on steps 5002, 5004, and 5006. Step 5008 may include step 5010. At step 5010, in a multiple program guide environment, a notification may be sent to specific users to which the content of the notification is related. For example, the notification may be sent only to users who used their program guides to select a particular program to be recorded. This may be achieved by sending one

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 149 notification using an e-mail and sending another notification via a program guide overlay. Other techniques may involve waiting to send a notification to a particular user until that user logs into his or her program guide. At step 5014, an opportunity to cancel or confirm the change identified in the notification may be provided to the recipient of the notification.

In a multiple program guide environment, each user that is notified of the change in the recorded content may be provided with an opportunity to confirm or cancel the change at step 5012. Information associated with each user's program guide will reflect whether that user selected to confirm or cancel the change. Step 5012 may be a substep of step 5014.

FIG. 78 shows an illustrative display sequence that may be provided based on the illustrative steps shown in FIG. 77. With reference now to FIG. 78, information display screen 5102 may contain information 5104, which describes an upcoming program, and may contain related program guide options such as record option 5106. An upcoming future program may be a program that will air in about a week. That program may be set to be recorded when record option 5106 is selected. If that program is set to be recorded, notification overlay 5108 may be displayed over video 5110 or other content shortly before that program is about to air.

Notification overlay 5108 may contain text notifying the user that the selected program is about to be recorded. Notification 5108 may include confirm option 5112 and cancel option 5114 to allow the user to select to confirm or cancel the recording of the program.

The program may have also been automatically selected for recording based on user viewing or recording activity that has been monitored, or based on other criteria.

FIG. 82 shows notification overlay 5502 that is the same as notification overlay 5302 of FIG. 80 except that the text information contained in overlay 5502 is different. Text 5506 in overlay 5502 of FIG. 82 informs that program XYZ is about to be deleted and informs that program XYZ was automatically selected to be deleted based on the automatic delete settings of the system. Automatic delete settings may be settings that are not under user control. Automatic delete setting may be configured to delete a program based on the date on which the program was recorded. Other techniques may also be used. A notification such as those illustratively shown in FIGS. 78-82 may be displayed for a particular user in a multiple program guide environment when that user is currently logged into his or her guide. If that user is not currently logged into his or her guide, the interactive television application may delay sending the notification until that user logs into his or her guide. If desired, the interactive television application may avoid such delays by sending an e-mail notification to that user.

- 153 illustrative e-mail embodiment in which e-mail 5802 is sent to inform an e-mail recipient that a particular program is to be recorded at a particular time and that the program was automatically selected to be recorded. E-mail 5802 may include reply region 5804 that may be used to reply to e-mail 5802. Reply region 5804 may be used to confirm or cancel the recording of the program. FIG. 86 shows an illustrative e-mail embodiment in which e-mail 5902 is sent to inform an e-mail recipient that a particular program is to be deleted based on automatic delete settings. An interactive reply region may be included in e-mail 5902 to allow a user to confirm or cancel the deletion of the program.

In a single or multiple program guide environment, an interactive television application may maintain a global list of programs that are available from a PVR. For example, with reference now to FIG. 87, at step 6002, a global list of programs that may currently be stored on a PVR may be generated and stored on user equipment or on a remote server. The global list may include programs that are in the recordings list(s) of the current users. Recordings may be included in the global list irrespective of whether they were recorded manually and automatically. At step 6004, programs that users deleted, but that are still available from the PVR may be kept on the global list. Step 6004 may be a substep of step 6002. If desired, programs that have been deleted and are no longer available may be included on the list.

At step 6006, an interactive television application will not record a program that is selected to be recorded (either automatically or manually) when that program is already on the global list. If desired, at

CA 02438947 2009-04-20

61009-643

- 154 step 6008, users may be permitted to edit the list. For example, a user may be provided with an opportunity to permanently delete a program that contains offensive materials. As another example, a user may remove a program from the list that was recorded, viewed, and deleted in the past, so that another copy of the program may be recorded and viewed.

A PVR or an integrated PVR-IPG may integrate content from a variety of platforms. For example, a PVR may store content from broadcast television, from payper-view, from video-on-demand, from the Internet, from radio, from multimedia devices (e.g., video and still cameras), from personal computers, etc. This content may be gathered based upon the same criterion or criteria.

The content may be made available to the viewer through any suitable interactive television application such as a program guide. Examples of interactive television program guides that have integrated content are illustratively shown in Walker et al., U.S. Patent

Application No. 09/829,856, filed April 10, 2001.

A PVR may be accessed and/or controlled remotely. PVRs or integrated PVR-IPGs may be connected to other equipment, including other PVRs (or integrated PVR-IPGs), via any suitable connection, such as a wired or wireless network to enable control of the PVRs and/or to enable content from PVRs to be accessed at other equipment. Examples of other equipment may include web phones, personal digital assistants, two-way pagers, ebooks, etc. Examples of interactive television program guides that provide remote access are illustratively shown in Ellis et al., U.S. Patent Application No.

Promotions such as advertisements may be stored on a PVR for presentation to users. Such stored advertisements may be related to advertisements that are airing to be viewed by television viewers. For example, with reference now to FIG. 88, at step 6102, a live video advertisement (e.g., an advertisement airing during a local station break) may be received for presentation and/or may be presented to a user. At step 6104, a locally stored advertisement that is related to the live advertisement may be presented to the user. The stored advertisement may be automatically selected for display based on user preferences or may be selected for display based on user selections. At 6106, a live video advertisement that is about to be presented to a user may be replaced with a particular recorded video advertisement. The recorded video advertisement may be automatically selected for display based on user information.

For example, with reference now to FIG. 89, video 6204 may be used to extend or replace live video 6202 for an automobile advertisement. Live video 6202 containing an advertisement for an automobile manufacturer may be displayed during a station break.

Video 6204 presenting an advertisement for a particular automobile model manufactured by that manufacturer may be displayed to a user from a local PVR following the presentation of video 6202. The stored advertisement may be selected for presentation based on user preferences. The stored advertisement may have been selected from among a number of different advertisements.

02/069636

PCT/US02/08043

156 If desired, a user may be allowed to view an extension of live video 6202 for a current advertisement. The interactive television application may display overlay 6206 over live video 6202 that provides the user with an opportunity to view an extension of the current advertisement. Video 6204 of a related advertisement that is an extension of the current advertisement may be displayed when a user selects to view an extension of the current advertisement from overlay 6206. In another technique, an interactive television application may replace a current live advertisement with.video 6204 of a recorded advertisement from a PVR. The recorded advertisement may be related to the current live advertisement and may be selected for display based on user information. If desired, the PVR may pause live television content when video 6204 is being displayed to a user.

A video advertisement that is stored on a PVR may be presented to a user when the user enters a program guide. FIG. 90 shows illustrative steps that may be involved in displaying video advertisements in a program guide. With reference now to FIG. 90, at step 6302, video advertisements may be stored on a recording device such as PVR for later presentation in an interactive television application. The video advertisements may be loaded during off-hours when user equipment is not likely to be used or loaded using any other suitable technique. At step 6304, an advertisement that was stored at step 6302 may be displayed when a user is using a program guide .

FIG. 91 illustratively shows two different sequences for the presentation of video advertisements. With reference now to FIG. 91, an interactive television

CA 02438947 2009-04-20

61009-643

- 157 application may display program listings display screen 6402 that contains video advertisement 6404 and interactive graphic advertisement 6406. Video advertisement 6404 may contain scaled video of an advertisement that is being presented using a PVR. Video advertisement 6404 may be selectable. Video 6412 may be displayed when a user selects video advertisement 6404. Video 6412 may present video advertisement 6404 in full screen.

Interactive graphic advertisement 6406 may be a graphic that is generated by the interactive television application to present a particular advertisement. Examples of interactive television program guides that include interactive graphic advertisements are illustratively described in Knudson et al.,

U.S. Patent Application No. 09/034,939, filed March 4, 1998. Video 6408, which presents a video advertisement that is related to graphic advertisement 6406, may be displayed when a user selects graphic advertisement 6406. If desired, related options overlay 6410 may be displayed over video 6408 to allow the user to further interact with respect to the advertisement.

A stored advertisement may be displayed when a user enters a program guide. For example, with reference now to FIG. 92, video 6504, which presents an advertisement that is stored on a PVR, may be displayed when a user who is watching video 6502 presses a remote control guide button. Main menu display screen 6506 may be displayed when video 6504 for the advertisement ends. If desired, video 6504 may be supplemented with text, graphics, interactive options, or other video.

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

158 Such video advertisements may be available not only from a local PVR, but also from remote storage devices, such as a remote storage device that is available in a client-server based program guide system. Examples of client-server based program guide systems are illustratively shown in Ellis et al., U.S. Patent Application No. 09/332,244, which is mentioned above. Remotely stored advertisements may be transmitted on demand, as part of a carousel, continuously, or using combinations thereof.

Buffer management techniques may be implemented with respect to television programming to enhance interactive services that are available to users. Buffer management techniques may be implemented to create new buffers based on current user activity. For example, with reference now to FIG. 93, at step 6602, user equipment that includes a PVR may be provided. The PVR may also be based on a remote server. At step 6604, a new straight buffer may be created on the PVR when a new channel or a new program is viewed by a current user.

An interactive television application may allocate a portion of the storage space on the PVR to a new buffer when that buffer is created. If desired, at step 6606, the interactive television application may allocate the size of the buffer to be a size that is suitable to hold the size of the program. If desired, buffer size may be increased incrementally to fit a program that is being buffered. At step 6608, video and/or audio from a program or channel currently tuned to may be stored to the buffer that is created when that channel or program is first tuned. For clarity and brevity, television content that is buffered is primarily referred to herein as video. The television content that

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

159 is buffered may not only contain video, but also contain audio, graphics, data, or other material.

With reference now to FIG. 94, first buffer 6702 may be created when a user first tunes to a first channel to view video 6704 of a first program. First buffer 6702 may have been allocated a size that is suitable to hold the remainder of the first program, which may, for example, be fifty minutes. Second buffer 6706 may be created when the user tunes to a second channel to watch video 6708 of a second program. The second channel may have been tuned to after the user watched the first program for ten minutes. Dashed region 6710 shown in first buffer 6702 represents what was buffered for the ten minutes that the first program was watched. The second program may have been watched to its completion, and the user may have stayed on the same the channel to watch the following program. Dashed lines 6716 are shown in second buffer 6706 to represent that second buffer 6706 holds the portion of second program that was watched by the user. Third buffer 6712 may be created when video 6714 of a third program commences following the end of the second program. Third buffer 6712 may have been allocated a size that is suitable to hold the length of the third program.

Storage space on a PVR may be selected to be allocated to a buffer in a number of different ways. For example, with reference now to FIG. 95, an interactive television application may be prompted to create a new buffer (e.g., a straight buffer) in step 6802. At step 6804, storage space that is not allocated to an existing buffer or is not allocated to a recording may be allocated to create the new buffer. If desired, at step 6806, one or more existing buffers (e.g., the oldest

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 160 existing buffer) may be deleted to make room for the new buffer. At step 6808, space from the deleted buffer(s) may be allocated to create the new buffer. Steps 6806 and 6808 may be performed simultaneously since allocating space to a new buffer may cause the deletion of the existing buffer. If desired, at step 6810, a portion of an existing buffer (e.g., the oldest portion of the oldest buffer) may be deleted to make room for the new buffer. At step 6812, space from the deleted portion may be allocated to the new buffer. Steps 6810 and 6812 may be repeated to increase the size of the newly created buffer. For example, in some instances, new buffers may initially be assigned to have a fixed length that may be incremented thereafter.

If desired, separate buffers that are for the same program may be combined into a single buffer. Illustrative steps involved in combining such buffers are illustratively shown in FIG. 96. With reference now to FIG. 96, at step 6902, a new buffer may be created when a user changes the current channel. At step 6904, separate buffers may be combined when the separate buffers contain video from the same program. In another implementation, an interactive television application may not create a new buffer when a user returns to viewing a program for which a buffer already exists. The interactive television application may simply store the program to the existing buffer.

FIG. 97 shows an illustrative buffering sequence that may be provided based on the steps shown in FIG. 96. With reference now to FIG. 97, first buffer 7002 may be created when a user changes the current channel to view video 7004 of a first program on a first channel. Second buffer 7006 may be created when the user

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 161 changes the channel to watch video 7008 on a second channel. The user may have changed the channel after watching the first program for ten minutes. The ten minutes of video 7004 that was buffered by first buffer 7002 is represented by dashed region 7010. After viewing video 7008 for the second program to its completion, the user may switch back to the first channel to watch video 7002 of the first program. Dashed region 7012 in first buffer 7002 represents video 7004 of the first program that has been buffered since the user returned to watching the first program. Thus, video that is buffered when a user returns to viewing a recent program is combined with what was buffered when the user first watched that program. Line 7014 in first buffer 7002 may mark the point at which the buffered video in dashed region 7012 was added to first buffer 7002. If desired, first buffer 7002 may include a gap at line 7014 that corresponds to the length of time that the user switched away from the current program.

Buffers that are for the same program may be combined in a number of different ways. For example, with reference now to FIG. 98, at step 7102, an interactive television application may buffer separately watched or tuned portions of the same program. For example, two separate portions of a program may be buffered when a user switches away and switches back to watching a particular program. At step 7104, the buffered portions of the program may be concatenated.

The concatenated buffer may not include any indicators to show that there is a break in buffered video. If desired, at step 7106, the buffered portions may be combined by inserting blank video or other content in between the buffered portions. Step 7106 may include

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

162 step 7108. At step 7108, the interactive television application may insert blank video, a stored advertisement, or other content that corresponds to the length of the gap in the video for a program between separately buffered portions. If desired, short content (such as blank video, text, or a graphic) may be inserted between the gaps, along with an indication of the length of time to display the content, so that buffer storage is not required for the entire missed timed period.

FIG. 99 shows three illustrative video presentation sequences that may be performed based on the steps shown in FIG. 98. Each sequence addresses how buffered video for nonadjacent portions of a program may be presented to a user. A user may be provided with an opportunity to rewind a program from a buffer. Video 7202 may be presented to a user when a user selects to play the program after rewinding the program to a first buffered portion of a particular program. Blank video 7204 may be displayed when the first buffered portion ends. Other content such as an advertisement stored on a PVR may also be used. Blank video 7204 may have been inserted to fill a break in the buffer. Video 7206 containing a second buffered portion of the program may be displayed when blank video 7204 has been displayed for a certain period of time (e.g., a time equal to the length of the gap in the program between the two portions).

In the next sequence shown in FIG. 99, the interactive television application displays text 7208 to inform the user of the existence of the break in the buffered video portions when video 7202 for the first buffered portions ends. Text 7208 may be presented over blank video or may be presented as part of a graphic.

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

163 Text 7208 may be displayed briefly, or it may be displayed for a period of time corresponding to the gap in the programming. In the final sequence that is shown in FIG. 99, video 7210 for a second buffered portion of a program is displayed immediately following video 7212 for the first buffered portion (e.g., the portions are concatenated). In this case, both video 7210 and 7212 may be displayed without displaying blank video or text to inform the user of a break in the buffer.

Gaps in buffers of program may be avoided by buffering programs in parallel. With reference now to FIG. 100, at step 7302, a user may be provided with an opportunity to change channels to watch different programs. At step 7304, programs may be buffered in parallel by implementing multiple tuners to buffer two programs at the same time. Multiple tuners may be implemented as part of a user's local user equipment. If desired, one or more of the multiple tuners may be implemented remotely. At step 7306, an interactive television application may record one program on a storage device (e.g., PVR) while a current user is watching a different program on a different channel.

This simultaneous watch/record feature may be provided when multiple tuners have been implemented. The multiple tuners may also allow the interactive television application to record two programs at the same time. Additionally, this implementation may allow the user to watch two or more programs at the same time, for example, by switching channels between the two programs and rewinding on each channel change to see the programming that was missed.

FIG. 101 shows an illustrative sequence of video and buffered management events that may be provided

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

164 based on the steps shown in FIG. 100. First buffer 7402 may be created for a first program when a user changes the channel to watch video 7404 of the first program airing on a first channel. Second buffer 7406 may be created for a second program when the user changes the channel to watch video 7408 of the second program.

Dashed region 7410 in first buffer 7402 represents video 7404 that was buffered before the user changed the channel. After watching the second program for ten minutes, the user may change the channel back to the first channel to return to the first program and may press a rewind key to rewind buffered video of the first program. The portion of the first program that was missed by the user may have been buffered while the user was watching the second channel. Dual tuners may be used to buffer both programs. Dashed region 7412 in first buffer 7402 shows that the interactive television application continues to buffer the first program after the user changes the channel. Thus, when the user returns to the first program and rewinds the first program, video 7410 containing the missed portions of the first program may be presented to the user.

A user may be permitted to access additional buffer content when the user rewinds a current buffer to the top of the buffer. The top of the buffer may refer to the earliest recorded content for the program. For example, with reference now to FIG. 102, at step 7502, a user may be allowed to rewind a video for a program using a buffer that was created for that program. At step 7504, the rewinding may be stopped and the program may be automatically played when the user rewinds to the top of the buffer. At this point, a user may select to rewind again from the top of the current buffer. In response,

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 165 the interactive television application may skip to the end of the previous program and rewind the previous program from the end of that program. A previous program may be a program that was previously watched by the user. In another example, a previous program may be a program that was previously recorded by the system but that may not have been watched by the user. Alternatively, at step 7508, the interactive television application may skip to the beginning of a previous program and may start to play that program when the user selects to rewind again after rewinding a current program to the top of the buffer for that program.

In the context of moving between programs that are available from program buffers, the movement may be based on the chronological order in which the buffers for the program were created.

FIG. 103 shows illustrative video presentation sequences that may be provided based on the steps shown in FIG. 102. With reference now to FIG. 103, video 7602 of a program rewinding may be displayed when a user selects to rewind a current program. When the user rewinds the current program to the top of the buffer for the current program, the interactive television application may stop the rewinding and may play video 7604 of the current program. If the user selects to rewind again from the top of the current program or buffer, the interactive television application may display video 7606 that shows video of a previous program rewinding. Alternatively, the interactive television application may play video 7608 for the previous program starting from the top of the buffer for the previous program.

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 166 A user may be permitted to fast-forward a program that is buffered. With reference now to FIG.

104, at step 7702, a user may be allowed to fast-forward video for a program that is buffered. At step 7704, the video for the program that the user has selected to fastforward may be automatically stopped when the end of that program or the end of the buffer for that program is reached. Alternatively, at step 7706, when the end of a program or the end of a buffer for a program is reached by fast-forwarding the program, the interactive television application may begin playing a following program using a buffer for the following program. In another alternative, the video for the following program may be fast-forwarded when the end of the first program is reached. The fast-forward and rewind techniques discussed herein may also apply to situations where buffers for a previous, current, or following program do not contain an entire program, but contain a portion of a program.

FIG. 105 shows an illustrative interactive sequence for presenting video that may be provided based on the steps of FIG. 104. As shown, video 7802 may contain video for a current program that is playing in fast-forward based on a user selection. A program buffer for the current program may be used to present video 7802. When the end of the current program is reached, the interactive television application may stop playing video 7802. Video 7804 from a currently tuned channel or a still frame from the stopped program may be displayed when the video 7802 is stopped. Alternatively, when the end of the current program is reached, video 7806 containing video for a following program may displayed.

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 167 Video 7806 may be video that is presented from a buffer. Video 7806 may play in fast-forward.

A user may be allowed to skip-forward when viewing buffered video for a program. For example, with reference now to FIG. 106, at step 7902, a user who is watching a program that is playing from a program buffer may be allowed to skip-forward to a next program. At step 7904, the interactive television application may skip to the top of the next program when the user selects to skip-forward. Similarly, a user may be allowed to skip backward between program buffers. With reference now to FIG. 107, video 8002 may contain video for a current program that is being presented from a program buffer for that program. Video 8004 for a next program in the buffer space may be displayed when the user selects to skip-forward past video 8002 of the current program.

Buffered programming may be saved as part of recording. FIG. 108 shows illustrative steps involved in recording a current program. For example, with reference now to FIG. 108, at step 8102, a current program that a user is watching may be buffered. At step 8104, the user may be provided with an opportunity to select to record the current program. At step 8106, the current program may be recorded by recording video that is currently airing and that is to air for that program and by saving video for that program that was recorded and is available from the buffer as part of the recording.

FIG. 109 shows an illustrative sequence of events for recording a current program that is provided based on the steps of FIG. 108. With reference now to FIG. 109, video 8202 containing video for a current program on channel 2 may be displayed when the user

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

168 selects to switch away from a program that the user was watching on channel 5. A buffer for the program on channel 5 may have existed when the user changed the channel to channel 2. After watching video 8202 for a period of time, the user may decide to switch back to channel 5. Video 8204 containing current video of the program on channel 5 may be displayed when the user selects to change the channel back to channel 5.

Overlay 8206 may be displayed when the user selects to record the current program on channel 5. The user may select to record the program on channel 5 by pressing a remote control record key when the user is watching video 8204 of that program. Overlay 8206 may inform the user that the current program on channel 5 is being recorded and that the recording for the program will contain portions of that program that were previously tuned. In a multi-tuner environment, the recording may include both previously tuned portions and portions that were missed by the user (e.g., missed because the user changed the channel to view another program). If desired, information in overlay 8206 may reflect the additional content that will be recorded in a multi-tuner environment.

A buffered program may be saved as a recording even after the completion of that program. FIG, 110 shows illustrative steps that may be involved in saving a buffered program as a recording. With reference now to FIG. 110, an interactive television application may keep a buffer for a program after the program ends. At step 8304, a user may be provided with an opportunity to have the program saved as a recording. At step 8306, the program may be saved as a recording from the buffer.

169 FIG. Ill shows an illustrative sequence of display screens that may be presented based on the steps shown in FIG. 110. Program buffer display screen 8402 may be displayed when a user selects a buffer listing option from an appropriate display screen (e.g., a main menu display screen) in a program guide. Program buffer display screen 8402 may include list 8404 identifying programs that are presently available from a buffer.

Information display screen 8408 may be displayed when a user selects listing 8406 for a documentary from list 8404. Information display screen 8408 may include information about the documentary and may include program-related options such as record option 8410. Record option 8410 may be selected to have the program buffer for the documentary saved as a recording. Recordings display screen 8416 may be displayed when the user later accesses the list of recordings that are currently available. List 8412 in recordings display screen 8416 may contain listing 8414 for the buffered program (the documentary) that the user selected to save as a recording. If desired, list 8404 in program buffer display screen 8402 may identify how much of a particular program was buffered. If desired, list 8404 in program buffer display screen 8402 may be modified to remove listing 8406 when a user selects that program to be recorded from the buffer. The buffer memory may be converted to program recording memory, or the program may be copied into program recording memory.

In another example of recording a program that has ended, the guide may allow a user to rewind or skip back to a previous program, as described previously. While watching a previous program, the user may be allowed to press a remote control info key to display

02/069636 PCT/US02/08043

- 170 program information screen 8408, or to press a remote control record key to record the program from the buffer.

The size of the storage space that is used to buffer programs may be set manually or automatically.

For example, with reference now to FIG. 112, at step 8502, a storage device such as a PVR may be provided as part of a user's local equipment. At step 8504, a portion (or all) of the storage space on the storage device may be assigned to buffering television content. Step 8504 may apply to single or multiple tuner environments. At step 8504, the size of the buffer space may be set automatically when the system is configured by a system operator or be set manually by the user. An example of setting the size of the buffer space automatically is automatically using all free storage space for program buffers. If desired, a minimum size of buffer space may be allocated automatically, even if that reduces the amount of programming that can be recorded.

With reference now to FIG. 113, buffer configuration display screen 8602 may be displayed when a user selects a buffer setup option from an appropriate display screen such as a main menu display screen or a PVR setup display screen. Buffer configuration display screen 8602 may include buffer space option 8604 that the user may use to select the total storage space that will be allocated to creating buffers, may include number of buffers option 8606 that may be used to select the maximum number of buffers that will be active at the same time, may include buffer size option 8608 that may be used to specify a fixed or maximum buffer size, and may include option 8610 for selecting when buffers will be deleted (e.g., deleted every day, every week, every month, etc.). If desired, there may not be an option to

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

171 select when buffers are deleted, as older buffers may be deleted when space is needed for newer buffers. Buffer size for each buffer may be set to a fixed size, may be set automatically based on program size, or may be set using other suitable techniques.

A recording device such as a PVR may be used to automatically pause television content when a user interacts with an interactive television application. Illustrative steps involved in pausing television content are shown in FIG. 114. With reference now to FIG. 114, at step 8702, television content such as video for a program or commercial may be presented to a user. The television content may be content that is currently airing, may be content that was previously recorded, or may be content that is playing from a buffer. At step 8704, the user may be provided with an opportunity to interact with an interactive television application. The interactive television application may for example be an interactive television application that has been implemented on a television system to provide interactive services to the user. At step 8706, the current television content that the user is watching may be automatically paused when the user starts to interact with the interactive television application. The current television content may be live television content or may be other television content such as a recorded program that a user is watching, a VOD program that a user is watching, etc. The user may start to interact with the interactive television application by for example pressing a remote control button. At step 8708, the display of the television content may resume when the user exits the interactive television application. The

172 television content may be resumed from the point at which was automatically paused.

FIGS. 115-120 show illustrative video and display screen sequences that may be provided based on the steps shown in FIG. 114. With reference now to FIG. 115, video 8802 of a television program that a user is currently watching may be automatically paused when the user enters a program guide by selecting a remote control guide button to display program listings display screen 8804. Program listings display screen 8804 may include listings 8806, which may be scrolled to find listings.

If desired, the user may take further actions to display other display screens after program listings display screen 8804 is displayed. Video 8808 of the television program, which the user was watching before entering the program guide, may be resumed from the point at which it was paused. The television program may be resumed when the user exits the program guide. Thus, a recording device such a PVR may be used to automatically pause content when a user interacts with an interactive television application.

With reference now to FIG. 116, video 8902 of a television commercial that a user is currently watching may be paused automatically when a user selects a remote control button such as an info button to display advertisement information display screen 8904.

Advertisement information display screen 8904 may contain information about the commercial that the user was watching. The user may interact with display screen 8904 and may further use other features in the interactive television application before exiting to video 8906.

For example, on receiving a recording, the recording may be added to the list of recordings available to the receiving user. On receiving a reminder, the interactive television application may set a reminder locally. On receiving a record request, the interactive television application may automatically schedule a local recording for the program. Examples of television messaging systems are illustratively shown in McKissick et al., U.S. Patent Application No. 09/356,245 filed July 16, 1999, which is hereby incorporated herein by reference in its entirety. If desired and as mentioned above, copy protection schemes may be provided for users with PVRs. Programming or other content that can be displayed on user equipment may be copy protected. Copy protection information that is associated with programming or other content may be provided to user equipment to support copy protection schemes. Copy protection schemes may be implemented that use the copy protection information to prevent users from copying programming or other content without authorization. For example, an interactive television application may block a program from being recorded to a PVR when that program is copy-protected. The recording

CA 02438947 2003-08-20

02/069636 PCT/US02/08043

- 178 of the program may be blocked by preventing the recording from being scheduled. A graphic (e.g., an overlay or display screen) may be displayed that informs a viewer that a particular program or other content that was selected to be recorded cannot be recorded due to copyright protections. The MPEG-4 standard may be used to transmit programs with information on copyright protections. Other standards that support such activity may also be used.

As mentioned above, a PVR may automatically record programs based on user preferences. Other inference engines may use information such as user demographics or keyword searches (mentioned above) to select programs to automatically record. Examples of interactive television program guides that use demographics are illustratively shown in Knee et al.,

U.S. Patent Application No. 09/139,777, filed August 25, 1998, which is hereby incorporated by reference herein in its entirety. Programs may be recorded automatically based on keywords that a user has entered into the system.

If desired and as mentioned above, conflict resolution schemes may be provided to support mechanisms for the viewer to resolve scheduling conflicts. An interactive television application may present options, configuration settings, or prompts that may be used by a user to resolve scheduling conflicts. Conflicts may be resolved by allowing a user to interact with the interactive television application to resolve each conflict as it arises. The interactive television application may also allow the user to set a conflict resolution scheme (e.g., set the interactive television

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

179 application to resolve scheduling conflicts in favor of one type of recording such as a series recording).

As mentioned above, personal video recorders and other digital recording devices record television programs onto a digital medium, such as a hard disk. The amount of programming that can be stored by such a device is limited by the capacity of the storage medium. A typical unit might store 30 hours of video programming, compressed at the maximum level.

Systems today use digital video compression methods such as MPEG-2, which are practical in real-time. An incoming audio/video program can be digitized, compressed, and stored as the signal is received. More efficient compression methods are available, such as MPEG-4. However, these methods are much more computationally intensive. Hardware that is inexpensive enough to be widely deployed may not be capable of compressing video using more efficient compression methods (e.g., using the MPEG-4 standard) in real-time.

The computational tasks associated with a digital video recorder are not in general excessive. A processor in such a device typically has spare processor cycles available. These spare cycles may be used to compress stored audio/video programs more efficiently.

For example, the system may record programs using the MPEG-2 standard, the same as other existing systems. However, in the background, using processor cycles that are not needed for storing, managing, and retrieving programs, the processor may scan through previously stored programs and compresses them in a more efficient format. After compressing a program in a more efficient format, such as MPEG-4, the less efficient

CA 02438947 2003-08-20

02/069636

PCT/US02/08043

180 version can be deleted, freeing up storage space for additional programs.

Programs may also be compressed in multiple passes. For example, it may make one pass through an audio/video file to reduce it in one way, and another pass to reduce it further. Each pass may eliminate a specific type of redundancy, for example. As each compression pass is completed, the previous version may be deleted.

The user, network operator, or programmer may be allowed to set parameters as to what types of compression are allowed, either in general or for a specific program. For example, a specific lossy type of compression may be optional. The more lossy types of compression may also be reserved for programs that are archived for a longer period of time, or which have already been viewed.

An advantage of this technique is that it allows many more hours of programming to be stored in the same amount of storage. For example, most or all of the program currently in progress may be stored in the least efficient format. Programs recorded recently may be stored in a more efficient format. And programs that have been stored for a longer period of time may be stored in the most efficient format.

A more advanced compression standard such as MPEG-4 may also allow for new features. For example, MPEG-4 allows objects in the video to be explicitly defined. A web address or commerce application could be linked to one of these objects. MPEG-4 supports management of intellectual property. These new features may be limited to programs that were originally broadcast in the MPEG-4 standard, or may be provided with other

CA 02438947 2012-11-07

- 181 formats by translating the information received into MPEG-4.

If desired, a computer readable medium such as a floppy disk, optical disk, etc. may be used to store machine executable code for implementing an interactive television application for providing PVR and/or IPG features. If desired, equipment such as the equipment discussed in FIGS. 1-2C may be configured to provide features, options, or techniques that are illustratively described herein.

Thus, exemplary embodiments of interactive television systems and methods that provide enhanced PVR and interactive television application features are provided. One skilled in the art will appreciate that numerous modifications are possible. Therefore, while the scope for patent protection is defined by the appended claims, the claims are not to be limited to the preferred or exemplary embodiments disclosed herei-n.
