## Title
Systems and methods for providing program suggestions in an interactive television program guide

## Abstract

An interactive television program guide application is provided that queries a user regarding the user's interest in television programs and suggests television programs to the user based on the user's responses. The interactive television program guide application identifies a television program that is potentially of interest to the user. The interactive television program guide application then queries the user regarding the user's interest using questions that are formulated based on attributes associated with the identified television program. Using the user's responses to the questions, the interactive television program guide application identifies and suggests one or more television programs to the user.

## Background
BACKGROUND OF THE INVENTION
This invention relates to television systems, and more particularly, this invention relates to interactive television systems such as interactive television program guide systems that suggest television programs to a user.
Cable, satellite, and broadcast television systems provide users with a large number of television channels. Users have traditionally consulted printed television program schedules to determine the programs being broadcasted at a particular time. As the number of available programs has increased, various television program guides, such as interactive television program guides, have been developed to help users select television programs of interest.
In some known systems, an interactive television program guide application allows a user to supply selection criteria which are used by the interactive television program guide application to select television programs that are of interest to the user. The selected television programs may be, for example, displayed for the user, recorded on a personal video recorder, or added to the user's favorite list. Interactive television program guide applications that select television programs for a user based on user-defined selection criteria are described, for example, in U.S. Pat. Nos. 4,706,121, 5,353,121, and 6,133,909.
Usually, the user of such known systems is required to specify a list of selection criteria and request a search based on the criteria to enable the interactive television program guide application to select television programs that are potentially of interest to the user. Such a process for providing a user with recommended programming can be tedious. Furthermore, some users may not even be aware that an option exists to allow specification of such selection criteria.
Accordingly, it would be desirable to provide an interactive television program guide application that automatically queries a user regarding the user's interest in various television programs to assist the user in selecting future television programs of interest.
SUMMARY OF THE INVENTION
In accordance with the present invention, an interactive television program guide application is provided that automatically queries a user regarding the user's interest in various television programs. The interactive television program guide application uses the user's responses to suggest to the user television programs that are potentially of interest.
In some embodiments of the present invention, the interactive television program guide application may monitor the user's television viewing pattern to identify a television program that is potentially of interest to the user. For example, the interactive television program guide application may determine that the user's viewing pattern associated with a television program satisfies one or more predetermined criteria for identifying potential television programs of interest (e.g., the user has continuously watched the television program for a time period that is greater than a predetermined time period). In making such a determination, the interactive television program guide application may mark the television program as a potential television program of interest.
The interactive television program guide application may then query the user using questions that are formulated based on attributes associated with the identified potential television program of interest. For example, the interactive television program guide application may determine from an attribute associated with the television program that the program is a movie having a sequel. In response to making this determination, the interactive television program guide application may formulate a question to prompt the user to set a reminder for the sequel.
Using the user's responses to the various questions, the interactive television program guide application may identify one or more television programs to suggest to the user.
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.

If the user has highlighted a particular program listing, for example, pressing the info button 90 may direct the interactive television application to provide additional program schedule information related to that program listing (e.g., a program summary, actor information, and any other suitable program schedule information).
Lock button 92 may be used to modify access privileges. For example, a parent may use lock button 92 or on-screen options to establish parental control settings for the interactive television application. The parental control settings may be time-based settings (e.g., to prevent a child from watching television during a particular time block such as from 3:00 PM to 5:00 PM). The parental control settings may also be used to block programming based on rating, channel, program title, or any other suitable criteria. A locked or blocked program is typically not viewable until the interactive television application is provided with a suitable personal identification number (PIN). Once this PIN has been entered, the interactive television program will unlock the user's equipment and allow the locked content to be accessed.
Exit button 94 may be used to exit the interactive television application or to exit a portion of the interactive television application. Guide button 96 may be used to invoke the interactive television program guide.
The keys shown in FIG. 4 are merely illustrative. Other keys or buttons may be provided if desired. For example, a music button may be used to access music with the interactive television application.

Alphanumeric buttons may be used to enter alphanumeric characters. A last or back button may be used to browse backward in the interactive television application (e.g., to return to a previous channel or display screen). Video recorder function buttons such as a play button, pause button, stop button, rewind button, fast-forward button, and record button, may be used to control video recorder functions (local or network-based) in system 10. A help key may be used to invoke help functions such as context-sensitive on-screen help.
Illustrative user computer equipment 22 is shown in FIG. 5. In the arrangement of FIG. 5, personal computer 98 may be controlled by the user using keyboard 100 or other suitable user input device, such as a trackball, mouse, touch pad, touch screen, voice recognition system, a remote control such as remote control 72 of FIG. 4, or any other suitable user input device. Video content such as television programming and interactive television application display screens may be displayed on monitor 102. Television programming, video-on-demand content, video recordings played back from a network-based video recorder, and other information may be received from paths 28 and 48 (FIG. 1) using input/output 104. The user may also send commands and other information used during interactions with the interactive television application and system 10 over input/output line 104.
Personal computer unit 98 may contain a television or video card such as television tuner card for decoding analog and digital television channels and for handling streaming video content. Multiple video cards (e.g., tuner cards) may be provided if desired. An illustrative television tuner card that may be used may contain an analog television tuner for tuning to a given analog channel and digital decoding circuitry for filtering out a desired digital television or music channel from a packetized digital data stream. Any suitable card or components in computer unit 98 may be used to handle video and other content delivered via input/output line 104 if desired.

Storage in personal computer unit 98 such as a hard drive, DVD drive, CD drive, or other suitable storage device or devices may be used to store video and other content. For example, the interactive television application and personal computer unit 98 may use this storage to provide the functions of a personal video recorder.
User equipment 18 such as user television equipment 20 and user computer equipment 22 may be used with network equipment such as server 56, server 36, and equipment at service providers such as service provider 50 of FIG. 1 to provide network-based video recording functions. Video recording functions may be provided by storing copies of television programs and other video content on a remote server (e.g., server 56 or server 36 of FIG. 1) or other network-based equipment such as equipment at a service provider such as service provider 50.
Video recordings may be made in response to user commands that are entered at user equipment 18. In a personal video recorder arrangement, the interactive television application may be used to record video locally on user equipment 18 in response to the user commands. In a network-based video recorder arrangement, the interactive television application may be used to record video or to make virtual recordings on network equipment such as server 36, 56, or equipment at service provider 50 in response to the user commands. The user commands may be provided to the network equipment over the communications paths shown in FIG. 1. The personal video recorder arrangement and the network-based video recorder arrangement can support functions such as fast-forward, rewind, pause, play, and record.
To avoid unnecessary duplication in a network-based video recorder environment, the system 10 may provide network-based video recording capabilities by using virtual copies or recordings. With this approach, each user may be provided with a personal area on the network that contains a list of that user's recordings. The video content need only be stored once (or a relatively small number of times) on the network equipment, even though a large number of users may have that video content listed as one of their recordings in their network-based video recorder personal area.
The user television equipment and user computer equipment arrangements described above are merely illustrative. A more generalized embodiment of illustrative user equipment is shown in FIG. 6.
As shown in FIG. 6, control circuitry 106 is connected to input/output 108. Input/output 108 may be connected to one or more communications paths such as paths 26, 27, 28, 42, 46, and 48 of FIG. 1. Television and music programming may be received via input/output 108 (e.g., from programming sources 12, servers or other equipment such as server 36, service providers such as service provider 50, and television distribution facility 14). Program schedule information for an interactive television program guide may be received from data source 30 via input/output 108. Input/output 108 may also be used to receive information from data source 30 for other interactive television applications. The user may use control circuitry 106 to send commands, requests, and other suitable information using input/output 108.
Control circuitry 106 may be based on any suitable processing circuitry 110 such as processing circuitry based on one or more microprocessors, microcontrollers, digital signal processors, programmable logic devices, or any other suitable processing circuitry. Memory (e.g., random-access memory and read-only memory), hard drives, DVD drives, CD drives, or any other suitable memory or storage devices may be provided as storage 112 that is part of control circuitry 106. Tuning circuitry such as one or more analog tuners, one or more MPEG-2 decoders or other digital video circuitry, or any other suitable tuning or video circuits or combinations of such circuits may also be included as part of circuitry 106. Encoding circuitry (e.g., for converting over-the-air or cable analog signals to MPEG signals for storage) may also be provided. The tuning and encoding circuitry may be used by user equipment 18 to receive and display or play or record a particular television or music channel or other desired audio and video content (e.g., video-on-demand content or requested network-based or local video recorder playback). Television programming and other video and on-screen options and information may be displayed on display 114. Display 114 may be a monitor, a television, or any other suitable equipment for displaying visual images. Speakers 116 may be provided as part of a television or may be stand-alone units. Digital music and the audio component of videos displayed on display 114 may be played through speakers 116.

An interactive television program guide having various interactive television program guide interface screens may be provided to assist a user in selecting television programs. Examples of the various interactive television program guide interface screens are described, for example, in Ellis U.S. patent application Ser. No. 10/306,175, filed Nov. 25, 2002, which is hereby incorporated by reference herein in its entirety.
As the number of available television programs grows, it becomes increasingly more confusing and burdensome for a user to select television programs that are of interest to the user. One approach to mitigate this problem is for an interactive television program guide application to suggest television programs to a user that may be of interest. For example, the interactive television program guide application may suggest television programs to the user based on the user's previous television viewing habits. The interactive television program guide application may derive the user's viewing habits by, for example, identifying and categorizing those television programs towards which the user has shown interest.
In some embodiments of the present invention, the interactive television program guide application may query the user as to the user's interests in television programs by using questions formulated based on those television programs towards which the user has shown interest. It will be understood that the term “questions” is not limited to textual queries but may include any suitable types of questions, prompts, options, or any other suitable tool for soliciting user responses. As an example, the interactive television program guide application may query the user regarding the user's preferences towards various actors in a television program using checkboxes. As another example, the interactive television program guide application may prompt the user to add a television program to a favorites list using a user-selectable button. As another example, the interactive television program guide application may provide an opportunity for the user to record a television program using, for example, a personal video recorder (PVR). As yet another example, the interactive television program guide application may prompt the user to schedule a television program for recording to a PVR by, for example, allowing the user to add the television program to a recording schedule. The interactive television program guide application may use various other suitable questions to automatically query the user regarding the user's interest. Some suitable approaches will be discussed in more detail below.
In one suitable approach, in response to determining that the user has shown interest towards a particular television program, the interactive television program guide application may formulate questions based on various attributes of the television program. These questions may then be displayed to the user by the interactive television program guide application at a suitable time. The suitable time for displaying these formulated question may be automatically determined by the interactive television program guide application or may be determined by the user. In some embodiments of the present invention, the interactive television program guide application may allow the user to initiate displaying of formulated questions by, for example, pressing a suitable button on a remote control (e.g., remote control 74 of FIG. 4). In some embodiments of the present invention, the interactive television program guide application may allow the user to specify, for example, during setup, suitable times for the interactive television program guide application to present formulated questions to the user.
Once the interactive television program guide application gathers responses to these questions, it may subsequently use the responses to identify television programs that are likely to be of interest to the user. Ultimately, these identified television programs may be recommended or otherwise displayed to the user as suggestions by the interactive television program guide application. The interactive television program guide application may automatically determine a suitable time for suggesting these television program to the user or the interactive television program guide application may allow the user to request for such suggestions. As an example, the interactive television program guide application may allow the user to request for suggestions by, for example, pressing a suitable button on a remote control (e.g., remote control 74 of FIG. 4). In some embodiments of the present invention, the interactive television program guide application may allow the user to specify, for example, during setup, suitable times for the interactive television program guide application to suggest television programs to the user.
FIG. 7 shows a general flowchart of illustrative steps involved in identifying television programs to suggest to the user based on the user's responses to tailored questions in accordance with some embodiments of the present invention.
At step 702, the interactive television program guide application determines that a television program is potentially of interest to a user. The interactive television program guide application may use various suitable approaches to determine potential television programs of interest. Some examples of suitable approaches will be described in detail below.
At step 704, the interactive television program guide application queries the user regarding the user's interest in television programs using one or more tailored questions. The questions are formulated based on one or more attributes associated with the television program that has been identified as a potential television program of interest by the interactive television program guide application at step 702.
The types of information that may be provided by the attributes associated with a television program may include, for example, category, type, genre, any other suitable information associated with the television program, or any combination thereof. In some embodiments of the present invention, additional attributes associated with, for example, a particular category, type, or genre of television program may also be identified. As an example, for a television program in the movie category, the interactive television program guide application may have access to additional attributes such as the cast members, director, producer, storyline, time period, or any other suitable attribute specific to a movie. In some embodiments of the present invention, the interactive television program guide application may also have access to relationship attributes that describe the television program's relationship with a past program, a future program, a related serial or any other suitable television programming. For example, in connection with a past television program, the interactive television program guide application may have access to relationship attributes that reveal any sequels, episodes in a serial, or any other suitable related television programs.
Once the interactive television program guide application gathers the user's responses to the questions, the interactive television program guide application then identifies one or more television programs to suggest to the user at step 706 that are based on the user's responses.
Detailed descriptions and examples of the various steps involved in identifying and suggesting television programs to a user based on queries using tailored questions will be discussed fully below.
The interactive television program guide application may use various methods to identify those television programs toward which the user has shown interest. For example, the interactive television program guide application may take note of the various television programs that the user has watched. This approach, however, may prove to be inaccurate in evaluating user interest due to the large number of television programs that the user browses that are not necessarily of interest to the user. To improve upon this approach, the interactive television program guide application may identify a smaller set of those television programs to which the user has shown more substantial interest.
In some embodiments of the present invention, the interactive television program guide application may determine whether the user is casually channel surfing past a television program or whether the television program has actually captured the user's interest in a more significant manner. The interactive television program guide application may make such a determination, for example, by monitoring the amount of time that the user spends watching the television program.
As an example, the interactive television program guide application may monitor the amount of time that the user spends watching a particular program in one continuous time period. The interactive television program guide application may then, for example, mark the television program that the user watches for a continuous period of time that is greater than a predetermined period of time as a potential program of interest. The interactive television program guide application may mark a television program as a potential television program of interest by, for example, inserting a flag into the data associated with the television program in a database (e.g., program listing information stored in a database), encoding such information into the datastream associated with the television program, storing a listing of the television program in a potential interest list, or using any other suitable approach to mark the television program so that the interactive television program guide application recognizes it as a potential television program of interest.
As another example, the interactive television program guide application may monitor the cumulative time that the user spends watching a particular television program. The interactive television program guide application may compute the cumulative time by, for example, adding together the time periods that the user has spent watching the particular television program during a time period within which the user has also watched other television programs (as opposed to continuously watching the particular television program, as described above). If the cumulative time exceeds a predetermined period of time, the interactive television program guide application may mark the television program as a potential program of interest.
As another example, the interactive television program guide application may monitor when the user stops watching a television program (e.g., when a commercial begins) and whether the user returns to watching the television program (e.g., after browsing through other programs). If the user returns to watching the television program, the interactive television program guide application may mark the television program as a potential television program of interest. In some embodiments of the present invention, the interactive television program guide application may treat turning off the television as an interruption that is similar to the commercial example described above. In response to a user turning the television back on, the interactive television program guide application may determine the length of time that the television had been turned off. If the time period that the television had been off is short, for example, when compared to a predetermined period of time, the interactive television program guide application may determine whether the user has returned to watching the television program that the user had been watching before turning off the television. If the user has returned to watching the same television program, the interactive television program guide may mark the television program as a potential television program of interest.
The examples described above are merely illustrative of the type of approaches that may be used to identify potential television programs of interest. Any other suitable approaches may be used.
FIG. 8 is a flowchart of illustrative steps involved in identifying a potential television program of interest in accordance with some embodiments of the present invention.
At step 802, the interactive television program guide application determines whether the user's viewing pattern associated with a television program (e.g., continuous viewing period, cumulative viewing period, or any other suitable viewing pattern indicator) satisfies one or more predetermined criteria for identifying a potential program of interest.
If the user's viewing pattern satisfies one or more predetermined criteria, the interactive television program guide application then marks the television program as a potential television program of interest at step 804.
Once the interactive television program guide application determines that the user has shown interest towards a particular television program using any suitable approach, the interactive television program guide application may use various characteristics of the television program to assist in identifying other television programs that may be of interest to the user.
In some embodiments of the present invention, the interactive television program guide application may formulate a series of questions in order to, for example, query the user regarding characteristics of the particular television program that may have made it interesting to the user. These questions may, for example, allow the user to add the television program or related television programs to the user's favorites list (e.g., when the television program is a part of a series of programs), allow the user to set reminders for the television program or related television programs, confirm the user's interest in various attributes associated with the television program (e.g., interest in a particular actor) for use in making future programming recommendations to the user, or obtain any other suitable information for identifying television programs of potential interest to the user.
The interactive television program guide application may formulate the questions displayed to the user by, for example, basing the questions on various attributes associated with the particular television program as described above. The various attributes associated with the particular television program may be predetermined by, for example, the distributor of the television program, content creator, or any other suitable source of the television program. The attributes associated with the television programs may be transmitted to the user equipment, for example, along with other interactive television program guide information.
Based on these predetermined attributes, when the interactive television program guide application identifies a potential television program of interest, the interactive television program guide application may formulate tailored questions to query the user regarding the user's interest in what have been identified as related television programs.
As an example, the interactive television program guide application may determine from an attribute associated with a potential television program of interest that the television program is an episode of a serial. Upon making such a determination, the interactive television program guide application may formulate a question that allows the user to add the serial to the user's favorite list. As another example, the interactive television program guide application may determine from attributes associated with a potential television program of interest that the program is a dramatic movie starring a particular actor. The interactive television program guide application may then formulate a question to query the user regarding the user's preference for other television programs starring the same actor or for other dramatic movies.
In some embodiments of the present invention, the interactive television program guide application may omit certain types of questions based on attributes associated with a television program. For example, upon determining that an attribute associated with television program reveals that the television program is a dramatic movie having no related television programs (e.g., sequels, serials, or any other suitable related television program), the interactive television program guide application may avoid the formulation of a question that prompts the user to add the movie to the user's favorites list. Based on this attribute, the interactive television program guide application may also determine that the user is not likely to want to view the same movie more than once, and may therefore avoid prompting the user to set a reminder for future occurrences of the movie.
It will be understood that while the interactive television program guide application may not display certain questions to the user based on attributes associated with a particular television program, the interactive television program guide application may nonetheless provide the user with the opportunity to request such options. For example, the user may request to add a movie to favorites, for example, by pressing a menu button on the user's remote control (e.g., remote control 72 of FIG. 4) to access favorites options provided by the interactive television program guide or using any other suitable request method.
FIGS. 9 to 11 demonstrate various questions that may be displayed to a user by the interactive television program guide application based on attributes that are associated with a potential television program of interest. While the examples of FIGS. 9 to 11 are shown as television screens in accordance with the present invention, it will be understood that various other types of screens, such as computer screens, screens of personal digital devices, or any other suitable display arrangement, may be used.
FIG. 9 shows an illustrative television screen 900 containing an interest survey window 902 associated with a movie in accordance with some embodiments of the present invention. Television screen 900 containing interest survey window 902 may be displayed to the user, for example, in response to the interactive television program guide application determining that the user has demonstrated interest in the movie “Braveheart” (e.g., by watching “Braveheart” for a continuous period of time that is greater than a predetermined period of time). The interactive television program guide application may continue to display video of the movie in video window 904, occupying the top portion of television screen 900. The interactive television program guide application may display one or more questions formulated based on attributes associated with the movie in interest survey window 902, which occupies the bottom portion of television screen 900. The interactive television program guide application may display interest survey window 902 as an overlay on top of video window 904 or in any other suitable arrangement.
Interest survey window 902 may include, for example, an advertisement 906, a list 908 of one or more questions formulated based on various attributes associated with the television program displayed in video window 904, directional key 910 for accessing additional questions, buttons 912, 914, and 916 for submitting, deferring, and skipping selections respectively, and any other suitable features. If the user selects button 912, the interactive television program guide application may gather the user's responses to the questions for use in identifying television programs to suggest to the user. If the user selects button 914, the interactive television program guide application may display interest survey window 902 or any other suitable interface having the same questions at a later time. If the user selects button 916, the interactive television program guide application may remove interest survey window 902 from television screen 900 and refrain from querying the user with the same questions again. In some embodiments of the present invention, if the user closes interest survey window 902 without answering any questions, the interactive television program guide application may display interest survey window 902 or any other suitable interface having the same questions to the user at a later time.
In this particular example, the interactive television program guide application has omitted any questions regarding saving the movie displayed in video window 904 to the user's favorites list. This is because one or more attributes associated with “Braveheart” indicate to the interactive television program guide application that “Braveheart” is a movie having no closely related television programs.
In the example of FIG. 9, the interactive television program guide application has determined from one of the attributes associated with the movie that Mel Gibson is the starring actor in this movie. Accordingly, the interactive television program guide application provides question 918 in list 908 to allow the user to indicate an interest in other television programs starring Mel Gibson. The user may confirm such an interest, for example, by setting toggle button 920 to “yes.” This may be accomplished by placing highlight region 922 on toggle button 920 and then using directional arrows on a remote-control (e.g., remote control 72 of FIG. 4) to toggle to choice “yes.” The interactive television program guide application also queries the user with questions 924 and 926 through which the user may confirm interests towards other attributes associated with the movie “Braveheart” (e.g., period epic, Scotland, or any other suitable attribute). The user may respond to these questions using toggle buttons 928 and 930, respectively.
Television screen 900 containing an interest survey window 902 is merely illustrative of such a display screen. Various other suitable arrangements may be used.
FIG. 10 shows another example of an illustrative television screen 1000 containing an interest survey window 1002 associated with a sporting event in accordance with some embodiments of the present invention. The interactive television program guide application may display interest survey window 1002, for example, in response to identifying “Monday Night Football” as a television program that is of interest to the user (e.g., by determining that the user has watched “Monday Night Football” for a continuous period of time that is greater than a predetermined period of time).
In the example of FIG. 10, the interactive television program guide application has determined from an attribute associated with “Monday Night Football” that it is a recurring television program. Accordingly, the interactive television program guide application has formulated and provided the user with question 1004 in the list of questions 1006 shown within interest survey window 1002 to enable the user to add “Monday Night Football” to the user's favorites list. In connection with this question, the user may select whether to add the program to the favorites list at the present time, at a later time, or never, using toggle button 1008. If the user chooses “yes,” the interactive television program guide application may add the program to the user's favorite list. If the user chooses “not right now,” the interactive television program guide application may query the user again at another time. If the user chooses “never,” indicating the user's lack of interest in this television program, the interactive television program guide application may refrain from querying the user in the future. In some embodiments of the present invention, in response to a user response of “never,” the interactive television program guide application may refrain from querying about or assign a lower priority to similar television programs in the future.
In the example of FIG. 10, the interactive television program guide application has also determined from other attributes associated with “Monday Night Football” that the game displayed for the user in video window 1010 is between the New York Giants and the New England Patriots. Based on this information, the interactive television program guide application may formulate questions 1012 and 1014 to allow the user to indicate an interest in these two teams using toggle buttons 1016 and 1018, respectively. Also in this example, the interactive television program guide application has determined based on a category attribute that “Monday Night Football” is a football event. Thus, the interactive television program guide application additionally displays question 1020 in interest survey window 1002 to query the user as to the user's interest in other football events. The user may respond to question 1020 using toggle button 1022.
Television screen 1000 containing interest survey window 1002 is merely illustrative of such a display screen. Various other suitable arrangements may be used.
FIG. 11 shows another example of an illustrative television screen 1100 containing interest survey window 1102 associated with an episode of a serial in accordance with some embodiments of the present invention. The interactive television program guide application may display interest survey window 1102, for example, in response to determining that the user has shown interest towards an episode of a serial. In this example, the interactive television program guide application has determined from attributes associated with the episode of “Mad About You” that the episode is related to one or more other episodes in a serial. In response to making such a determination, the interactive television program guide application prompts the user with questions 1104 and 1106 to allow the user to add the serial to the user's favorites list and to set reminders for future episodes of the serial, respectively.
In this example, the interactive television program guide application has also identified, through examination of the associated attributes, that the serial casts actress Helen Hunt. Accordingly, the interactive television program guide application provides the user with question 1108 regarding the user's interest in other television programs starring Helen Hunt. The user may confirm such an interest, for example, by setting toggle button 1110 to “yes.”
Television screen 1100 containing interest survey window 1102 is merely illustrative of such a display screen. Various other suitable arrangements may be used.
As described above, as the user watches television, the interactive television program guide application may automatically determine if the current television program is a potential television program of interest. Once the interactive television program guide application identifies the television program as a potential television program of interest, the interactive television program guide application may formulate questions associated with the television program as the user watches the program. In some embodiments of the present invention, the interactive television program guide application may also formulate questions associated with the television program after the user has finished watching the television program. Suitable time for formulating questions associated with a television program may be automatically determined by the interactive television program guide, pre-determined by the content distributor, determined by the user (e.g., during setup), or determined using any other suitable approach. The interactive television program guide application may then display the formulated questions to the user at a suitable time. For example, the interactive television program guide application may display the questions to the user during the presentation of the television program, immediately after the presentation of the television program, during a commercial break, in response to the user switching channels, in response to the user turning on the television, or at any other suitable time. Some suitable approaches for displaying the formulated questions to the user are described in detail below.
In one suitable approach, the interactive television program guide application may display questions formulated in association with a particular television program when the user initiates interaction with the program guide during the presentation of the particular television program. The user may initiate interaction with the program guide by, for example, requesting display of the guide, changing channels, or using any other suitable approach. In another suitable approach, the interactive television program guide application may display the questions to the user in response to the user initiating interaction with the program guide within a predetermined time period after the end of the particular television program. In yet another suitable approach, the interactive television program guide application may automatically display the questions to the user at the end of the particular television program or at any other suitable time determined by the interactive television program guide application.
FIG. 12 shows a flowchart of illustrative steps involved in displaying to the user at a suitable time questions formulated in association with a potential television program of interest in accordance with some embodiments of the present invention.
At step 1202, the interactive television program guide application identifies a suitable time for displaying to the user questions that have been formulated in association with a potential television program of interest using any suitable approach.
The interactive television program guide application then displays the questions formulated in association with the potential television program of interest to the user at step 1204.
Once the interactive television program guide application has gathered the user's responses to the various questions, the interactive television program guide application may assist the user in selecting television programs of interest in various ways. In some embodiments of the present invention, the interactive television program guide application, in response to the user invoking a favorites view of the guide (e.g., a program guide view containing user favorites information, including the user's favorites list), may prominently display those favorite programs that are about to start. The interactive television program guide application may also provide to the user, in the favorites view, those suggested television programs that have been identified by the interactive television program guide application. For example, the interactive television program guide application may have identified these suggested television programs by using the user's responses to questions previously displayed to the user.
FIG. 13 shows one example of an illustrative favorites screen 1300 in accordance with some embodiments of the present invention. Favorites screen 1300 may prominently display in the top portion of the screen a list 1302 of favorite programs that are about to start. The user may adjust the time frame for displaying the favorite programs using directional arrows 1304 and 1306. Alternatively, the user may use suitable directional buttons on the user's remote control (e.g., remote control 72 of FIG. 4) or any other suitable means for adjusting the time frame.
Favorites screen 1300 may also include a suggested television program list 1308. The interactive television program guide application may have identified these suggested television programs using at least partially, for example, the user's responses to questions previously displayed to the user. Suggested television program list 1308 may be sorted to prominently display those suggested television programs that are about to start (e.g., at the top of the list).
The user may access additional favorite programs and additional suggested programs by scrolling down favorites list 1302 and suggested television program list 1308 using arrows 1310 and 1312. Alternatively, the user may access complete lists of favorite programs and recommended programs by selecting “favorites list” button 1314 and “recommended” button 1316, respectively.
In some embodiments of the present invention, the interactive television program guide application may include in favorites screen 1300 options to provide the user with preview information on interesting upcoming television programs. In this particular example, favorites screen 1300 includes “coming up today” button 1318 and “coming up this week” button 1320 to provide the user with such information. In response to a user selection of “coming up today” button 1318, for example, the interactive television program guide application may refresh favorites screen 1300 to display to the user a list of television programs coming up on the present day that are in the user's favorites list, having been identified as suggested television programs, or both. Similarly, in response to a user selection of “coming up this week” button 1320, for example, the interactive television program guide application may refresh favorites screen 1300 to display to the user a list of television programs coming up in the current week.
In this particular example, a “previously watched” button 1322 is provided on favorites screen 1300. In response to the user selecting “previously watched” button 1322, the interactive television program guide application may display to the user a previously watched screen 1400, as shown in FIG. 14, in accordance with some embodiments of the present invention. Previously watched screen 1400 may be similar in layout to favorites screen 1300 of FIG. 13. However, in place of the user's favorites list, the interactive television program guide application may display a previously watched list 1402 of those television programs that the user has shown interest towards, but has not yet added to the user's favorite list (e.g., the user has previously selected “not right now” when asked whether the user would like to add the program to favorites).
The interactive television program guide application may prominently display on previously watched screen 1400 those television programs that are about to start. In this particular example, the interactive television program guide application provides options 1404, 1406, and 1408 for the user to select whether to add any of these previously watched programs to the user's favorites list. If the user again chooses “not right now,” the interactive television program guide application may keep the television program on previously watched list 1402 to be displayed to the user at a later time. However, if the user chooses “never,” or if the user ignores the television program on previously watched list 1402 for a predetermined period of time, the interactive television program guide application may remove the television program from previously watched list 1402.
Previously watched screen 1402 is merely illustrative of such a display screen. Various other suitable arrangements may be used.
In some embodiments of the present invention, the interactive television program guide application may bring to the user's attention favorite and suggested television programs that are scheduled to air in or near a time frame. The time frame may be a time frame within which the user is currently browsing, for example, in the interactive television program guide listings.
FIG. 15 is a flowchart of illustrative steps involved in alerting the user to listings of favorite television programs, suggested television programs, or both, that are within or near the time frame that the user is currently browsing in the program guide in accordance with some embodiments of the present invention.
At step 1502, the interactive television program guide application identifies one or more listings of favorites television programs, suggested television programs, or both, that are within or near a user-selected time frame. For example, the user-selected time frame may be the time frame that the user is currently browsing (e.g., in a program guide). The interactive television program guide application then alerts the user to the one or more favorite television programs, suggested television programs, or both using, for example, a suggestion overlay such as suggestion overlay 1600 of FIG. 16 (step 1504).
FIG. 16 shows a suggestion overlay 1600 that may be displayed by the interactive television program guide application to alert the user of favorite programs and suggested programs that are within or near a user-selected time frame in accordance with some embodiments of the present invention. In this particular example, program listings window 1602 shows that the user is currently browsing program listings in the 12:00-12:30 pm time frame on Thursday. In response to determining that favorite programs as well as suggested programs are available within or near this time frame, the interactive television program guide application displays suggestion overlay 1600 containing a list of these television programs. The interactive television program guide application may allow the user to close suggestion overlay 1600 using close button 1604. In some embodiments of the present invention, the interactive television program guide application may allow a user to prevent the interactive television program guide application from displaying suggestion overlay 1600, any other pop-up windows (e.g., containing questions associated with a television program), or any combination of overlays and windows thereof. For example, the interactive television program guide application may provide an option for the user to disable displaying of these overlays and pop-up windows during set-up.
Suggestion overlay 1600 is merely illustrative of such a display screen. Various other suitable arrangements may be used.
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.
