FIG. 7 is a flowchart showing a processing flow of the mobile phone 11 and the content presentation device 15 in the recommended content notification system 10.

  As shown in FIG. 7, in the content presentation device 15, the related information acquisition unit 81 and the content analysis unit 84 acquire the related information of the content including the feature words that characterize the content of the viewable content, and the related information storage unit 91. (S20).

  Specifically, when the content is broadcast via a broadcast wave, the related information acquisition unit 81 acquires the related information of the content from the EPG received by the broadcast wave reception unit 62. On the other hand, when the content is broadcast via the communication network 18, the related information acquisition unit 81 acquires the related information of the content from the tag information attached to the content acquired by the IP broadcast acquisition unit 80. In addition, the content analysis unit 84 analyzes the content acquired from the broadcast wave reception unit 62 or the IP broadcast acquisition unit 80, and acquires frequent feature words as related information of the content.

  On the other hand, in the mobile phone 11, the voice recognition unit 40 performs voice recognition on the voice data of the user A and the call partner acquired from the voice processing unit 24 and converts them into text data (S 10, acquisition step). Next, the feature word extraction unit 41 extracts feature words that characterize the contents of the converted text data (S11, extraction step), and repeats these steps S10 and S11 until a predetermined period elapses (S12).

  When the predetermined period elapses, the interest information creation unit 42 assumes that the feature word that appears frequently among the feature words extracted in the most recent predetermined period is information that is of interest between the user and the other party. Interest data including words is created and transmitted to the content presentation device 15 (S13). Then, it returns to step S10 and repeats the above-mentioned operation.

  On the other hand, the content presentation device 15 repeats step S20 until the interest information acquisition unit 85 receives the interest data from the mobile phone 11 and stores it in the interest information storage unit 92 (S21). When the interest data is received, the matching analysis unit 86 collates the feature words included in the interest data in the interest information storage unit 92 and the feature words included in the related information of the content in the related information storage unit 91 (S22, Decision step). Then, based on the result of the collation, the recommended content specifying unit 87 specifies the recommended content and presents it to the user A (S23, notification step). Then, it returns to step S20 and repeats the above-mentioned operation.

  In the present embodiment, the matching analysis unit 86 compares the feature words of the related information of the content and the feature words of the interest data to calculate the number of matching words, but is not limited thereto. It is not something. For example, the first interest data shown in FIG. 3 includes a word representing the time “weekend” as a feature word. Therefore, the matching analysis unit 86 obtains the day (2012/05/04 to 2012/05/06) corresponding to the first weekend from the extraction date (2012/05/01) of the first interest data, and the obtained day. And comparison with the broadcast time included in the related information shown in FIG. 5 may be further performed. In this way, related information other than the feature words of the content may be compared with the feature words of the interest data.

  In the present embodiment, the recommended content is notified only to the user A, but the recommended content may be notified to both the user A and the user B. This can be realized by changing the mobile phone 12 of the user B to the same one as the mobile phone 11 of the user A and adding the content presentation device 15 to the user B.

  Note that there may be a case where recommended content differs between user A and user B due to different viewable content. Therefore, a server that is communicably connected to the communication network 18 is added, and the server receives the recommended content list shown in FIG. 6 from the content presentation devices 15 of the user A and the user B, and receives the received two You may notify to the content presentation apparatus 15 based on the difference of a list.

  Thereby, for example, when the content of the local broadcast that can be viewed only by the user A is the recommended content, that fact can be presented to the content presentation device 15 of the user B. As a result, for example, the user B can request the user A to record the content. In addition, when the content of the pay broadcast subscribed only by the user B is the recommended content, the content presentation device 15 of the user A can indicate that the subscription to the pay broadcast is recommended.

  Various processes can be considered as processes after the content presentation device 15 presents the recommended content to the user A. For example, when the user A selects any of the presented recommended contents via the operation unit 64, the content presentation apparatus 15 transmits information on the selected recommended content in the list shown in FIG. Transmit to the telephone 11. The mobile phone 11 of the user A specifies the user B who is the partner ID included in the information received from the content presentation device 15, starts a video conference with the mobile phone 12 of the specified user B, and is selected as described above. The recommended content can be viewed together.

  In this embodiment, recent interest data is used, but past interest data may be used. In this case, it is possible to reduce the possibility that a matching feature word cannot be found in the matching of the matching analysis unit 86 by referring to the recent and past interest data regarding the same call partner.

  Further, the content analysis unit 84 acquires information that can be associated with content from servers such as an electronic bulletin board site, a blog site, and a chat site, and extracts frequent feature words from the acquired information. The feature word may be added to the related information of the content and stored in the related information storage unit 91.
