In addition, more easy-to-use recording systems represented by HDD recorders are becoming widespread. In addition, as the number of broadcast programs to be viewed by users increases with the diversification of broadcast programs, there is a need for users to watch only the scenes they want to watch instead of watching all the scenes.

  Patent Document 1 discloses that TV program information existing on the Internet is used to collect and use values indicating interest for each scene.

JP 2005-295266 A

  The method of collecting program-related information via the Internet and collecting the interest level of the program based on the magnitude of the response requires an Internet connection environment. In addition, the amount of information of a program that is not generally watched is limited, and the meaning of the information itself may be due to the interest of a certain individual. Also, even if there is a lot of information that shows interest in the program, it may not mean that it is interesting. Furthermore, although it is thought that it follows the direction of general interest, it may not always follow the user's own preferences.

  Therefore, an object of the present invention is to provide a broadcast receiving apparatus and an information viewing apparatus that can view information according to user preferences.

  An information receiving apparatus capable of viewing information, the extracting means for extracting preference data indicating information that the user of the information receiving apparatus has viewed in the past, the receiving means for receiving information, and the extracting means Calculation means for calculating similarity between the information received by the receiving means using preference data and the information viewed in the past, and received by the receiving means using the similarity calculated by the calculation means And reproducing means for reproducing information selected from the information.

  ADVANTAGE OF THE INVENTION According to this invention, the broadcast receiving apparatus and information viewing apparatus which can view the information according to a user preference can be provided.

  FIG. 1 is an example of a configuration of a broadcast receiving apparatus. The broadcast receiving apparatus 101 can receive broadcast programs and has a function of temporarily storing broadcasts. The broadcast receiving apparatus 101 may be a one-segment terrestrial digital signal built in a mobile phone. The TV program broadcast by the broadcast 114 is stored in the reception information storage area 102. The reception information storage area 102 is also a reception buffer for smoothly receiving and reproducing TV programs broadcast by the broadcast 114.

  The reception information storage area 102 receives information once at the reception information input 103, but this is not reproduced in real time, but is stored in the reception information discharge seat area a little ahead. This accumulated broadcast is actually reproduced in the broadcast reproduction 106 as the reproduction information output 104.

  In the present invention, the subtitle content included in the broadcast is extracted by the subtitle content analysis 105 while the broadcast once stored by the reception information input 103 is actually reproduced by the reproduction information output 104, and the extracted subtitle is extracted. Based on the information, by calculating the similarity in the user preference and preference information quantification 107, which is stored in the preference information storage 113 in advance, if this value exceeds a certain value, The notification means 109 can be used to notify the user of the broadcast receiving apparatus 101 that a broadcast that is likely to be of high interest to the user will be notified soon. It is also possible to adjust the interval between the received information input process 103 and the reproduction information output process 104 as appropriate. Further, as means for notifying that there is a broadcast that may be of high interest to the user soon, a vibrator 110, an alarm 111, a flash 112, and the like can be considered. Vibrator 110 is generally used for mobile phones and the like. Also, in this embodiment, it is assumed that the user's interest is high using the subtitles included in the broadcast, and this is assumed to be received by the subtitle content analysis process 105 and the preference information quantification process 107. For example, it is possible to recognize a voice state, an image state, etc. as a scene with a high degree of interest of the user and notify the user via the notification means 109 in the same manner. Needless to say.

  Next, a configuration example of an information viewing system using a broadcast receiving device and a portable viewing device will be described with reference to FIG. This is an embodiment in which a user's interest level is applied to information recorded in advance, instead of receiving broadcasts in real time. The broadcast 114 received by the broadcast receiving apparatus 101 is input as the reception information input 103 to the reception information storage area 102 and then stored in the recording data 203 via the recording output 202. In this recording, subtitle information is extracted in subtitle content analysis 105, and user preference information stored in preference information storage 113 is used in preference information quantification 107 and extracted in subtitle content analysis 105. The subtitle information thus recorded is recorded in the recording data 203 as numerical data. The recorded data can of course be reproduced by the broadcast receiving apparatus 101. For example, the recorded data 203 is transferred to the portable viewing apparatus 201 using the data transfer means 204, and the preference data extraction process 210 is used. It can be played back by the broadcast playback processing 211. In the preference data extraction process 210, for example, it is conceivable to use only a scene in which the preference information digitization 107 is 6 or more. Specifically, a news program or the like can be automatically selected and reproduced by a user only in news of a favorite genre such as economic news, social news, and sports news. In addition, I think that there is also usage such as playback for each preference ranking.

  Next, a user preference extraction algorithm using caption (text) information will be described with reference to FIG. If there is past reference text information 301 that the user has referred to in the past, this past reference text information 301 is, for example, text information included in iEPG of TV broadcasts that have been viewed in the past, Web pages that are always referenced, and transmission / reception Text information extracted from e-mail etc. The appearance rate of the words included in the referenced text in the document and the co-occurrence rate that is the probability that a plurality of words are present in the same document at the same time are accumulated. The information accumulated by the user in the past is stored together with the word in the appearance rate and co-occurrence probability 305 of the word included in the information referred to in the past. In addition, the words included in the current reference text 302 extracted from the caption information and the like this time are temporarily stored as the appearance rate and co-occurrence rate 304 of the words included in the current reference text. In addition, the information of all the words referred to regardless of the personal preference of the past reference text information 301 and the current reference text 302 is accumulated in the appearance rate and co-occurrence rate 303 of all the extracted word information. Using the accumulated information as input, similarity calculation is performed using the similarity calculation algorithm 306 to determine whether the current reference text 302 is similar to the past reference text 301. This result is calculated in the form of similarity for each reference text 302 this time, and a reference text similarity 307 is calculated. Generally, when there is no similarity, “0” takes a positive value when an appearance rate of some word or a co-occurrence rate exists. The larger this value is, the more the current reference text 302 is similar to the past reference text, and this includes contents close to the user's preference.

  Next, a data flow in the information viewing system will be described with reference to FIG. In this case, the portable viewing device 201 that is always carried is provided with a preference data collection function 402. A specific example of the portable viewing device 201 is a mobile phone. The text information referred to by the user via the portable viewing device 201 is text that leads to the preference of the user. The portable viewing device 201 collects data connected by preference from text information, and provides the broadcast receiving device 101 with communication means. The information passed from the portable viewing device 201 is temporarily stored as user preference source data 405, and user preference data 407 is generated using a user preference data generation algorithm 406. This is synonymous with the appearance rate and co-occurrence rate 305 of words included in the information referred to in the past. Also, the broadcast receiving apparatus 101 performs broadcast program recording at the program recording 408. At this time, subtitle information is extracted for each scene by subtitle information extraction processing 409, this subtitle information is processed by user preference data 407 by scene interest degree analysis 410, and similarity calculation algorithm 306 is set for each extracted subtitle. Apply, calculate the similarity for each caption information, and store it in the interest 412 for each scene. This data is combined with the recording data 411 to generate preference viewing data 413. This data can of course be reproduced by the broadcast receiving device 101, but can be viewed by the portable viewing device 201 that is always carried by providing it to the portable viewing device 201 using some communication means. . At this time, it is possible to use the preference utilization function 404 by extracting a scene with a certain level of similarity or higher from the interest level 412 for each scene and selectively reproducing it. Furthermore, among the preference viewing data 413, for those that are repeatedly viewed, the preference data is further collected as preference data via the preference data collection function 420, thereby further improving the accuracy of the preference data. be able to.

  FIG. 5 shows a sequence flow in the information viewing system. The mobile viewing device 201 collects text information referred to by the user through the preference data collection 402. The referred text data is sent to the broadcast receiving apparatus 101 as user preference (original) data 501. The broadcast receiving apparatus 101 uses the user preference data generation 406 to generate user preference data from now on. This preference data can be sent to the portable viewing device 201 by the user preference data 502, and the portable viewing device 201 uses this data for the preference utilization function in the portable viewing device by the preference utilization function 404. Is possible. The broadcast receiving apparatus 101 can perform program recording by the program recording function 408. Subtitles are extracted from the recorded broadcast program by subtitle information extraction 409, and are converted into numerical values in the form of interest by scene based on the subtitle information included in the broadcast program by scene interest analysis 410. The digitized information is sent to the portable viewing device 201 as recording / scene preference data 503 together with the recorded broadcast program. The portable viewing device 201 can be played back using the preference data by the preference program playback function 403. Further, the preference source data viewed by the user and collected by the viewing behavior is sent to the broadcast receiving apparatus 101 as user preference (source) data 504, and this sequence is repeated. The portable viewing device 201 continues to collect data by the preference data collection function 402 in order to continuously collect user preference source data.

  FIG. 6 is an example of the user preference graph 601. The horizontal axis shows the passage of time, and the vertical axis is the absolute value of the user's degree of interest. The larger this value is, the closer to the preference data that the user is referring to, that is, the more interested the user is. By selecting and playing a scene based on this value, only the scene interesting to the user can be selected and played.

  An example of a sequence flow intended for real-time reception will be described with reference to FIG. The real-time broadcast playback 701 stores broadcast programs received in real time in the reception information storage area 707 using the broadcast temporary recording function 702. This area does not store all, but may temporarily store broadcast data. The temporarily stored broadcast program is sequentially extracted with subtitle extraction processing 703 and compared with data stored in user preference data 708 with interest determination processing 704. This user preference data 708 is in agreement with the user preference data 407. When the degree of interest that exceeds this value is calculated in the interest level comparison processing 705, the notification processing 709 notifies the user that the user will be interested in the scene. For example, when this processing is a portable information device with a built-in TV reception function, it is possible to notify that a scene that the user is interested in is approaching by a vibrator or an alarm. Since the received broadcast is temporarily stored in the reception information storage area 707, it can be played back with a delay from the time of reception for a certain period of time. It is possible to receive a notification to that effect immediately before the scene that seems to be possible.

  According to the above embodiment, when the user is watching the broadcast, the user is notified that the scene is of interest immediately before the scene in which he / she is interested. It becomes possible to do. In addition, the basic data for determining the scene that interests you is automatically generated based on information such as the program that the person watched and the information that the person referred to, such as emails. In addition, it is possible to watch a scene that only the person himself is interested in. In addition, by applying this to a previously recorded program, it can also be applied to viewing and viewing that extracts only the scene of interest.
