  Next, the operation will be described. The broadcast receiving terminal 100 receives the EPG from the broadcast receiving means 101 and stores it in the EPG storage unit 109. Information stored in the EPG storage unit 109 is managed by the EPG management unit 110.

  A broadcast is received from the broadcast receiving means 101 in response to a user operation or an instruction such as reserved recording, and the recorded video is stored in the recorded video storage unit 106. The information stored in the recorded video storage unit 106 is managed by the recorded video management unit 107.

  User history such as viewing, recording, package software playback information, Internet access information, and mail description information is stored in the history information storage unit 102.

  Operation history such as viewing history, recording history, package title playback history, Internet access history, mail transmission / reception history, and the like is stored in the history information storage unit 102. An operation when the user displays a user interface for operating the terminal-specific functions on the broadcast receiving terminal 100 will be described.

  The preference information extraction unit 103 extracts user preference information from the information stored in the history information storage unit 102 by, for example, the following operation. The viewing history stores information on programs that have been selected and viewed for a certain period of time as preference items. The program information includes a program name extracted from the EPG, a program genre, a series name, a performer name, and the like.

  It is determined that a user's preference is high for a preference item having a high appearance frequency from a plurality of viewing histories.

  The recording history stores recorded program information as a preference item. The program information is the same as the viewing history. Further, information such as recorded but not reproduced or recorded but only partially reproduced is stored as a non-preference item.

  From a plurality of viewing histories, it is determined that the user's preference is high for a preference item having a high appearance frequency, and the user's preference is determined for a non-preference item having a high appearance frequency.

  As a package title viewing history, for example, US Pat. No. 6,061,680 discloses a method of acquiring title information of an arbitrary CD package medium. Title information of various package media can be acquired using a mechanism similar to this, and title names or album names, performer names or artist names, genres, series information, etc. are stored as preference items.

  It is determined that a user's preference is high for a preference item having a high appearance frequency from a plurality of viewing histories.

  The connection history of the access site stores the name, genre, selected keyword, and searched keyword as preference items. It is determined that a user's preference is high for a preference item having a high appearance frequency from a plurality of connection histories. For keywords, a dictionary may be used to determine that synonyms are the same.

  The text information history of mail stores keywords such as proper nouns including person names and content title names appearing in the mail text as preference items. If there is a language analysis function, it is also possible to store keywords in sentences including negation as non-preference items.

  As described above, it may be determined that a preference item having a high appearance frequency in each operation history has a high preference, but a preference item having a high appearance frequency across a plurality of operation history types has a higher preference. It becomes possible to judge. Similarly, it is possible to determine that a non-preference item having a high appearance frequency across a plurality of operation history types has a lower preference.

  In addition, for a search result based on a preference item with high preference, that is, with a high frequency of appearance, a previously viewed title is removed from a plurality of viewing histories, or with low preference, that is, with a frequency of appearance that is not high The title that matches the item can be removed and presented to the user.

  In addition, the preference item that is a frequently appearing keyword in the access site and mail operation history may be a preference item that does not appear in the viewing history, recording history, and package title viewing history. It is possible to present to the user from various perspectives.

  That is, when analogy from the operation history, it seems that the preference is high, but the user can be urged to notice when the user is not aware of the target.

  In addition, it is possible to prevent the same title from being presented each time by randomly presenting a plurality of top titles that are determined to have high palatability. Moreover, what is not selected no matter how many times it is presented may be reflected in the operation history as a title that has already been viewed or has a low preference.

  In addition, preference items with a high frequency of occurrence within a certain period from the current date and time, recent preferences, and preference items with a high frequency of occurrence before a certain period are judged as past preferences, and the past, current, and potential preferences are used. By performing the matching presentation contents at random, it is possible to avoid the same contents being presented each time.

  Since the viewing history of the VOD title that has been selected and viewed can be managed by specifying the broadcast receiving terminal on the VOD distribution server side, the broadcast receiving terminal is recognized on the server side, and the search history of the presented title is automatically detected. Remove it. It is also possible to record the viewing history on the broadcast receiving terminal side and reflect it in the preference information to process on the broadcast receiving terminal side.

  As a method for extracting preference information from a plurality of different operation histories in addition to the method described above, for example, Patent Document 3 (Japanese Patent No. 3714310) has been reported, but the preference extraction method used in the present invention is limited to these methods. is not.
