  Here, the above-described electronic program guide will be described. The electronic program guide is acquired via the signal processing unit 47 (that is, the electronic program guide is acquired from a broadcast signal) or is acquired via the LAN terminal 82 (that is, the electronic program guide is acquired via the Internet). ) The electronic program guide includes attribute information of a plurality of contents and manages a broadcast schedule of the plurality of contents. For example, the attribute information of the predetermined content includes the title of the predetermined content, broadcast time information of the predetermined content (broadcast start time information, broadcast end time information, broadcast time), genre information of the predetermined content (the predetermined content is a comedy ( Comedy), sports, drama (impressive drama) information), performer information of this predetermined content (talent A, talent B, etc.), and keywords of this predetermined content (beauty, Korea, diet, etc.) )including. Further, based on the display instruction of the electronic program guide input from the operation unit 71 or the display instruction of the electronic program guide from the remote controller 72 input via the light receiving unit 73, the acquired electronic program guide is displayed on the video display unit. 57.

  Next, an example of preference information management will be described with reference to the flowchart shown in FIG.

  For example, first, the control unit 61 performs an electronic program guide based on a predetermined channel selection instruction input from the operation unit 71 or a predetermined channel selection instruction from the remote controller 72 input via the light receiving unit 73. Controls playback of predetermined content on a managed predetermined channel. Correspondingly, the video of the predetermined content is output to the video display unit 57, and the audio of the predetermined content is also output to the speaker 56. The viewing history management unit 111 manages a viewing history indicating that the predetermined content is viewed in correspondence with the reproduction of the predetermined content. For example, this viewing history includes viewing time information of predetermined content.

  The sensor unit 101 extracts feature information of the viewing user in real time (ST1), and the user identification unit 102 identifies the viewing user based on the feature information extracted in real time, and the user is extracted from the extracted feature information. Information is extracted (ST2). For example, the sensor unit 101 is a camera, the characteristic information is face image information of the viewing user, and the user information is the evaluation value of the attention level and the expression evaluation value of the viewing user (see FIG. 4). In addition, user information is not limited only to these, Furthermore, you may include the voice, gesture, etc. which are detected by a sensor. For example, the user identification unit 102 analyzes the face image information, detects the viewing direction of the viewing user, and calculates the evaluation value of the attention level based on the detected viewing direction. In other words, the evaluation value of the degree of attention is information indicating how much the viewing user has viewed the content. Also, the user identification unit 102 analyzes the image information, detects the viewing user's smile level, and calculates the evaluation value of the facial expression based on the detected smile level. As described above, the user information items may be increased (attention level, facial expression, voice, gesture, etc.) to detect the viewer's emotions and calculate the evaluation value of the facial expression based on these. . The extracted user information is registered in the user information database 103 together with the extraction time.

  Subsequently, the viewing content extraction unit 112 acquires the predetermined content viewed at a predetermined time based on the viewing history managed by the viewing history management unit 111 (ST3), and is further viewed from the electronic program guide at the predetermined time. The attribute information (detailed information) of the predetermined content is acquired (ST4), and the attribute information of the predetermined content viewed at a predetermined time is provided to the preference determination unit 105. In addition, the preference information unit 104 provides user information extracted at a predetermined time registered in the user information database 103 to the preference determination unit 105.

  The preference determination unit 105 calculates the satisfaction level of the viewing user for the predetermined content based on the attribute information of the predetermined content viewed at the predetermined time and the user information extracted at the predetermined time, and evaluates the predetermined content (ST5). The satisfaction level of the viewing user with respect to the predetermined content is calculated based on the evaluation value of the attention level with respect to the predetermined content, the evaluation value of the facial expression with respect to the predetermined content, and the electronic program guide (attribute information of the predetermined content). More specifically, the preference determination unit 105 calculates a satisfaction level corresponding to the genre of the predetermined content in the attribute information of the predetermined content (whether the satisfaction level is calculated from the evaluation value of the attention level and the evaluation value of the facial expression). Whether or not the satisfaction level is calculated based only on the attention level evaluation value), and at least the attention level evaluation value and the facial expression evaluation value based on the selected satisfaction level calculation method are used. Satisfaction with the predetermined content is calculated.

  For example, the preference determination unit 105 calculates the satisfaction degree based on the attention value evaluation value and the expression evaluation value for calculating the satisfaction degree of the content of the first genre (for example, a comedy program). A method is selected, and a second satisfaction degree calculation method for calculating the satisfaction degree based on the evaluation value of the attention degree is selected for calculating the satisfaction degree of the content of the second genre (for example, an emotional program). This is because the evaluation value of the attention level becomes an element of satisfaction common to all contents, whereas the evaluation value of facial expression (smile level) does not become an element of satisfaction common to all contents. is there. For example, if the evaluation value of the attention level of the viewing user with respect to the comedy program is high and the evaluation value of the facial expression (smile level) is also high, it is determined that the satisfaction level is high. On the other hand, if the evaluation value of the attention level of the viewing user with respect to the emotional program is high, it is determined that the satisfaction level is high regardless of the evaluation value (smile level) of the facial expression.

  FIG. 5 is a diagram illustrating an example of the satisfaction level calculation for each genre. Satisfaction (50%) is obtained from the evaluation value (90%) of the attention level and the evaluation value (10%) of the facial expression obtained corresponding to the content reproduction of the first genre (comedy). This case is an example in which the satisfaction degree is calculated slightly lower because the evaluation value of the attention level is high but the evaluation value of the facial expression is low. Further, the satisfaction level (90%) is obtained from the evaluation value (90%) of the attention level obtained corresponding to the content reproduction of the second genre (impressive drama). This case is also an example where the evaluation value of the attention level is high and the evaluation value of the facial expression is low, but the evaluation value of the facial expression is excluded from the elements for calculating the satisfaction level, so that the satisfaction level is calculated higher.

  The preference information unit 105 determines the viewing user's preference based on the attribute information of the predetermined content and the degree of satisfaction with the predetermined content, and uses the viewing user's preference information obtained based on the result of the viewing user's preference determination as the user preference. Registration in the sex database 106 (ST108). For example, the preference information is configured by a plurality of item-specific preference information. That is, the preference information includes preference information for genres, preference information for performers, and preference information for keywords. For example, according to the attribute information of the predetermined content, the genre of the predetermined content is “comedy”, the performer of the predetermined content includes “talent A”, and the keyword of the predetermined content includes “beauty”. If the satisfaction level for the predetermined content is 50%, 50 points are added to the comedy as the preference information for the genre, and the talent as the preference information for the performer. 50 points are also added to A. For the keyword “beauty”, the number of appearances is counted (+1). In this way, the preference information unit 105 collects preference information from satisfaction with a plurality of contents, for example, searches for genres that have acquired 1000 points or more, searches for performers that have acquired 500 points or more, Search for keywords that appear 10 times or more.

  As shown in FIG. 6, the preference information unit 105 generates a content satisfaction ranking based on the calculated satisfaction, generates a performer ranking (person ranking) based on the preference information, Keyword ranking can be generated based on In addition, the palatability information unit 105 can also register a genre or keyword of content with a particularly high level of user satisfaction as a favorite (ST106, YES) (ST107).

  Note that the preference information can be fed back to the user, and the preference information can be processed into more accurate information. For example, the preference information registered in the user preference database 106 is displayed on the video display unit 57, and the preference determination unit 105 is based on a preference information correction instruction from the remote controller 72 input via the light receiving unit 73. Correct the preference information. For example, the score acquired by the talent A is added or subtracted.

  The recommended program management unit 107 can detect recommended content from the electronic program guide based on the preference information registered in the user preference database. Alternatively, the recommended program management unit 107 can detect recommended content from the electronic program guide based on the above ranking. For example, content of a genre that has acquired 1000 points or more is detected as recommended content, content in which a performer who has acquired 500 points or more is detected as recommended content, or performers up to 3rd in the performer ranking appear Content to be detected as recommended content, or content including keywords up to the third keyword ranking can be detected as recommended content. Further, the OSD signal generation unit 54 outputs an OSD signal corresponding to the recommended content information to the video display unit 57 (see FIG. 7), or the electronic program guide management unit 614 displays a mark indicating recommendation in the program column of the recommended content. Or output an electronic program guide with.

  In addition, the signal processing unit 47 converts the video signal and audio signal of the recommended content detected by the recommended program management unit 107 into a predetermined recording format, and records it in the external storage device via the LAN terminal 82 or the USB terminal 84. You may make it do.

  Next, the satisfaction level of the predetermined content will be described in more detail, and playback control using the satisfaction level will be described.

  The user identifying unit 102 calculates the evaluation value of the attention level for each reproduction time of the predetermined content, and the preference determination unit 105 also calculates the satisfaction level for each reproduction time of the predetermined content. The preference determination unit 105 generates attention level and satisfaction level transition information corresponding to the playback time of the predetermined content as shown in FIG. 8 by combining the attention level evaluation value, the satisfaction level, and the viewing history of the predetermined content. To do. As shown in FIG. 8, the evaluation value of the attention level is high in the shooting scene, but since the shooting is missed, the viewing user is disappointed and the evaluation value of the facial expression is lowered, resulting in a decrease in satisfaction.

  For example, assuming that the predetermined content is recorded in an external storage device connected to the LAN terminal 82 or the USB terminal 84, the recommended program management unit 107 pays attention to the reproduction time of the predetermined content. The reproduction of the recorded predetermined content is controlled based on the degree and satisfaction transition information. For example, based on an attention scene reproduction instruction input from the operation unit 71 or an attention scene reproduction instruction from the remote controller 72 input via the light receiving unit 73, the recommended program management unit 107 has a degree of attention above a predetermined level. Only scenes corresponding to the evaluation value of are searched for and played back. In addition, based on the satisfaction scene reproduction instruction input from the operation unit 71 or the satisfaction scene reproduction instruction from the remote controller 72 input via the light receiving unit 73, the recommended program management unit 107 satisfies the satisfaction level of a predetermined level or higher. Search and play back only scenes corresponding to.

  Below, the preference information management of this embodiment is summarized.

  Corresponding to the reproduction of the predetermined content, the sensor unit (camera, etc.) acquires user information (attention level, facial expression, etc.) in real time, and is acquired by a method according to the attribute information of the predetermined content included in the EPG. Satisfaction is calculated from the information and the predetermined content is evaluated. Furthermore, the user's preference for the predetermined content is determined from the attribute information and satisfaction of the predetermined content, and the viewing user's preference information obtained based on the result of the viewing user's preference determination is stored.

  In other words, the satisfaction level for all contents is not calculated uniformly based on the evaluation value of the audience's attention level and the evaluation value of the facial expression, but the satisfaction level is calculated by a satisfaction level calculation method according to the content attribute information (type). To do. For this reason, more accurate satisfaction can be calculated, and as a result, the preference information becomes more accurate.

  In this embodiment, content with high satisfaction, genre with high palatability, performers with high palatability, keywords with high palatability are detected, and the information is guided or detected based on the information. Although cases have been described in which recommended content is recommended, further recorded, and scenes with high satisfaction are extracted and played back, the present invention is not limited to this. For example, content with low satisfaction, genres with low palatability, performers with low palatability, keywords with low palatability may be detected, such information may be guided, or scenes with low satisfaction may be skipped and played back it can.

  In the present embodiment, as described above, user identification by the user identification unit 102 is possible, and preference information can be managed for each user by using this user identification.

  Note that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention in the implementation stage. In addition, the embodiments may be appropriately combined as much as possible, and in that case, the combined effect can be obtained.
