Patent Application
20070156589
The present invention relates generally to electronic program guides, and more particularly, to improved methods and computer programs for integrating personalized program listings into an electronic program guide.
Electronic program guides are utilized in conjunction with media delivery systems such as cable television, satellite television, and subscription-based interactive television. These guides store information indicative of the scheduled times at which each of a plurality of programs will be offered on each of a plurality of channels. When displayed on a media presentation device such as a television, the electronic program guide presents users with a menu of available programs from which to choose. By way of illustration, many cable systems provide all subscribers in a particular geographically defined television market with an electronic program guide that includes programs from a specified set of local network affiliates, as well as programs from a plurality of nationwide cable channels.
Subscription-based interactive television systems, such as TiVo, ReplayTV, EchoStar, and UltimateTV, use electronic program guides in conjunction with programs that may be viewed in the future, as well as programs that have already been recorded for subsequent viewing. These systems include program receiving devices equipped with memory for storing a subscriber's favorite television show, and a recording mechanism for automatically making a digital recording of the program each time it airs. In the case of TiVo, software is sent to the program receiving device for providing the subscriber with special interactive features, including the ability to manipulate recorded programs by pausing, rewinding or instantly replaying a portion of the broadcast, without missing succeeding action. UltimateTV includes a video processing mechanism by which users are able to receive Internet-based content. ReplayTV provides personal video recorders that allow users to search for programs based on keywords, such as an actor's name or the name of a movie.
Existing electronic program guides have significant shortcomings. Due to the large number of content providers, a user must oftentimes search through numerous program listings to locate a desired program. For example, electronic program guides may list all over-the-air broadcast networks such as ABC, CBS, NBC, PBS, Fox, UPN, WB, Univision, and Telemundo, as well as a multiplicity of cable outlets including the Discovery Channel, Nickelodeon, ESPN, CNN, HBO, Showtime, Movie Channel, and others. Users may fail to spot a desired program listing, or may disregard an unfamiliar program listing that, nonetheless, would be of interest to the subscriber. What is needed is an improved electronic program guide from which a user is able to readily and expeditiously select one or more programs of interest.
Exemplary embodiments include methods for integrating personalized listings of media content into an electronic program guide. The methods comprise retrieving a user profile setting forth information about a user's preferences. Media content information is received that is indicative of at least one of a media type, a title, or descriptive information, for each of a plurality of available media selections. A media content recommendation is generated for the user by applying the user profile to the media content information, the recommendation setting forth at least one recommended media selection. The at least one recommended media selection is presented for display within the electronic program guide.
These methods can also be viewed as providing computer program products for integrating personalized listings of media content into an electronic program guide. The computer program products include a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for facilitating a method. The facilitated method includes retrieving a user profile setting forth information about a user's preferences. Media content information is received which is indicative of at least one of a media type, a title, or descriptive information, for each of a plurality of available media selections. A media content recommendation is generated for the user by applying the user profile to the media content information, the recommendation setting forth at least one recommended media selection. The at least one recommended media selection is presented for display within the electronic program guide.
Other exemplary embodiments include systems for integrating personalized listings of media content into an electronic program guide. These systems comprise a computer-readable storage medium for storing a user profile setting forth information about a user's preferences; a communications mechanism for receiving media content information indicative of at least one of: (i) a media type, (ii) a title, or (iii) descriptive information, for each of a plurality of available media selections; a processing mechanism, coupled to the communications mechanism and the computer-readable storage medium, for generating a media content recommendation for the user by applying the stored user profile to the received media content information, the recommendation setting forth at least one recommended media selection; and a display mechanism, in communication with the processing mechanism, for displaying the at least one recommended media selection within the electronic program guide.
Other systems, methods, and/or computer program products according to embodiments will be or become apparent to one with skill in the art upon review of the following drawings and detailed description. It is intended that all such additional systems, methods, and/or computer program products be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.
Referring now to the drawings wherein like elements are numbered alike in the several FIGURES:
The detailed description explains exemplary embodiments of the invention, together with advantages and features, by way of example with reference to the drawings.
Content providers 113 are capable of providing media content information describing available media content to an electronic program guide service provider 111. Illustratively, media content information is provided in the form of one or more keywords or other preference information, such as titles for each of a plurality of available media selections. Media content information may also include an identifier setting forth a media type, such as a movie, concert, TV show, radio broadcast, live performance (i.e., play, opera), sporting event, or interactive game. If the media type is a movie, then the media content information may identify one or more actors participating in a movie, as well as a movie genre (horror, science fiction, etc). If the media type is a concert, then the media content information may include a musical genre (jazz, classical, heavy metal, etc.). If the media selection type is a sporting event, then the media content information may identify two or more teams participating in the event, as well as a sporting event category (football, baseball, etc.). For a media selection that occurs at a prescheduled time, the media content information may identify a date and a time of day at which the media selection is scheduled to occur.
Electronic program guide service provider 111 includes a database of users 118 stored on a computer-readable storage medium such as a disk drive, magnetic storage medium, semiconductor memory, optical storage medium, or the like. Illustratively, database of users 118 is stored in the form of a list of media delivery network users who are authorized to access media content on content providers 113, such as a first user (user1) 102 and a second user (user2) 104. However, database of users 118 does not include information indicative of media preferences for the media delivery network users listed therein.
For one or more users identified in database of users 118, a user-specific user profile is stored in profile database 101. In the present example, profile database 101 stores user profiles for user1102 and user2104. User1102 may represent an individual user, whereas user2104 may represent a household comprised of a plurality of individuals. Profile database 101 is illustratively implemented using a computer server and a computer-readable data storage medium such as a disk drive, semiconductor memory, magnetic storage medium, optical storage medium, or the like.
The user profiles stored in profile database 101 include any information that is indicative of a user's preference for media content, such as keywords or other preference information relating to a preferred subject matter for media content, keywords or other preference information describing preferred genres of media content, keywords or other preference information describing preferred media types, identities of one or more frequently accessed content providers, and/or names of preferred actors, musicians, artists, performers, directors, or athletes who create media content. Illustrative subject matter keywords include, but are not limited, to “cooking”, “football”, “antiques”, and “fishing”. Examples of preferred genre keywords include, but are not limited, to “science fiction”, “action/adventure”, and “horror”. Media types include categories such as film, podcasts, music videos, television, radio, and others.
User profiles in profile database 101 are derived using information received from a user, information concerning past viewing habits of the user, known demographic information regarding the user, user information obtained from third party sources, information obtained upon the user subscribing to the media delivery network, or various combinations thereof. User profile keywords or other preference information could, but need not, be automatically generated for a user by monitoring media selections made by the user over a period of time. For example, if a user views a substantial number of Star Trek episodes, the keyword “science fiction” would be placed into this user's profile. Similarly, if the user views a number of programs carried by the NBC television network, the keyword “NBC” would be placed into this user's profile.
The user profile may, but need not, be created by means of a user entering information into a web interface 103 which then conveys the entered information over the Internet 105 to profile database 101. Profile database 101 may, but need not, be stored locally in a media presentation device 121. Media presentation device 121 represents any device capable of generating audible, visual, or audiovisual output from an electronic signal received from a media delivery network 117. Illustratively, media presentation device 121 is implemented using an analog television set in combination with a set-top box, a television set capable of demodulating and processing signals in digital form, a computing device that includes an electronic display or an audio output port or both, or a radio receiving device capable of demodulating and processing signals in digital form. If profile database 101 is stored in media presentation device 121, then updates to the profile database can be performed locally by the user without the necessity of traversing media delivery network 117. Illustratively, media presentation device 121 could be programmed to display one or more menu screens by which profile database 101 may be edited or updated.
Web interface 103 may be implemented using a personal computer, laptop computer, or other computing device that is capable of communicating over the Internet 105. The entered information could include one or more keywords, or other preference information indicative of a user preference. Optionally, web interface 103 may be capable of implementing a dialogue with a user so as to elicit information for entry into the user profile.
Optionally, the user profile may be derived from information received from the user in the context of a service provider-customer relationship. For example, a user wishing to subscribe to media delivery network 117 may be required to submit a credit card number, street address, telephone number, and other billing information to a service provider. This information is indicative of the economic status of the user, and could be placed into the user profile.
A prediction engine 107 receives a user profile, such as a profile for user1102, from profile database 101. Prediction engine 107 may be implemented by a computing device such as a computer server, a group of computer servers, a mainframe computer, a personal computer or a laptop computer. In addition to user profiles, prediction engine 107 receives media content information from content providers 113. Based upon the information contained within a user profile, such as a profile for user1102, and media content information received from content providers 113, prediction engine 107 generates at least one media content recommendation for user1102.
The media content recommendation sets forth a recommended media selection available from content providers 113. Searching through media content information received from content providers 113, the media content recommendation is generated by identifying one or more selections that most closely provide a match for the user profile when substantially all media selections included in the media content information are considered. Illustratively, the media content recommendation is generated by identifying media content information that is substantially identical, similar, or related to any of the keywords or other preference information in the user profile.
Electronic program guide service provider 111 provides an electronic template for a media content guide. The template is received by an electronic program guide application 119. The at least one recommended media selection generated by prediction engine 107 is also received by electronic program guide application 119. Electronic program guide application 119 is programmed to place the at least one recommended media selection into the electronic template to generate a completed template. Optionally, additional media content information from content providers 113 is placed into the completed template. Using the completed template, electronic program guide application 119 is programmed to generate an electronically displayable media content guide for display on a media presentation device 121. Since the media content guide incorporates at least one selection generated by prediction engine 107, the guide is thereby customized for a specific user, such as user1102.
Electronic program guide application 119 may reside at media presentation device 121, media delivery network 117, or both. Media delivery network 117 represents any network component, connectable to media presentation device 121, which is capable of electronically conveying media content from content providers 113 to media presentation device 121. By way of example, media delivery network 117 comprises a cable system head end, a residential gateway, a media server, or an over-the-air antenna that receives broadcasts from content providers in the form of terrestrial and/or satellite television stations.
Preferably, electronic program guide application 119 is programmed to place the at least one recommended media selection at or near the top of the media content guide as the guide is displayed on a media presentation device 121. In addition or in lieu of placing the at least one recommended media selection at or near the top, the at least one recommended media selection may be placed within a prominent or highlighted region of the media content guide as the guide is displayed on media presentation device 121.
Electronic program guide application 119 may, but need not, be programmed to generate a media content guide organized chronologically in a graphical or tabular format, so as to provide a menu of programs, movies, concerts, performances, or events that are to occur at each of a plurality of prescheduled times. However, the available media content may also include programs, movies, concerts, performances, or events that may be played back on demand at any time. Items that are available on demand could, but need not, be listed in a separate portion of the media content guide that is not chronologically organized.
Pursuant to a set of further embodiments disclosed herein, an optional aggregator 109 searches the Internet 105 for media content. Upon locating an item of media content on the Internet 105, aggregator 109 stores information identifying the media content in an optional media content database 115. In addition to storing information identifying the media content, media content database 115 is also capable of storing a uniform resource locator (URL) comprising an Internet address for the item of media content. Items of media content may include electronic files stored on computer-readable storage devices, as well as Internet web sites offering streaming video, streaming audio, or other types of media content. Accordingly, when prediction engine 107 is generating a media content recommendation as described above, the prediction engine may perform a search of media content located by aggregator 109 and stored in media content database 115, in lieu of, or in addition to, performing a search of media content information received from content providers 113.
“Media type” is used to categorize each of a plurality of available media selections into one of several media categories, such as movie, concert, TV show, radio broadcast, live performance, sporting event, or interactive game. In the case of a sporting event, “title” may specify the names of the teams participating in the event. The title of a concert may include the names of one or more performers or groups participating in the concert. The titles of TV shows, radio broadcasts, live performances, and movies are self-explanatory. “Descriptive information” is used to provide one or more keywords or other preference information related to the subject matter or genre of available media selections. If a media selection is a movie, “descriptive information” may indicate a science fiction movie from the Star Trek series.
Next, the user profile is applied to media content information, so as to generate a media content recommendation for the user (

Optionally, the operational sequence of blocks 415-423 is repeated for each of a plurality of media types, such as music, audiovisual programs, and games, to generate a personalized list of preferred program predictions for each of a plurality of different media types. These personalized lists are generated by the prediction engine from the user's profile as retrieved from the profile database, and the personalized lists are then transmitted via the media delivery network and the media presentation device to the remote control. The remote control is equipped with an optional “media type” button which, when activated, causes the media presentation device to initiate scanning through all programs on the personalized list of preferred program predictions for a first media type. Upon subsequent activation of the “media type” button, the media presentation device initiates scanning through all programs on the personalized list of preferred program predictions for a second media type.
Some of the preferred program predictions in Randy's Channel 401 and Susie's Channel 403 may be broadcasts that occur at a prescheduled time, such as the Wife Swap program on ABC, whereas other preferred program predictions may be on-demand programs available for download from the Internet, such as a 1982 football game between Northwestern and Michigan. Illustratively, if no preferred program prediction in the form of a broadcast is predicted for a given user in a given time slot, then the preferred program prediction is generated by considering on-demand programs available from the Internet. For example, in the 10:00-11:00 PM timeslot, Randy's Channel 401 includes an on-demand football game because no broadcast program was predicted for Randy during this time. During some scheduled periods, such as the 9:00-10:00 timeslot, both Randy's Channel 401 and Susie's Channel 403 indicate the same preferred program prediction, such as “Lost” on ABC. However, during other time periods, including 8:00 PM to 9:00 PM, Randy's Channel 401 and Susie's Channel 403 indicate different program predictions. Randy is predicted to prefer an NPR podcast, whereas Susie is predicted to prefer “Wife Swap” on ABC.
