Description

  The present invention relates to a content recommendation device and program for recommending video content, various types of information, and advertisements in conjunction with video content in television broadcasting, commercials, package media, and recorders, and a recording medium.

  In recent years, services associated with digital information such as EPG have been provided as a result of higher functionality of television receivers and digitization of television broadcasts. In addition, the use of hard disk video recorders (hereinafter referred to as DVRs) that record and play back TV programs as digital signals has been developed. By using a hard disk, flexible playback operations such as skip playback and variable speed playback for recorded TV programs are possible.

  On the other hand, with the development of the Internet and personal computers (hereinafter referred to as “PCs”), the usage of supplementing the contents and contents that could not be communicated in the program on the homepage of the broadcasting station that produced the TV program has spread. is doing.

  There is data broadcasting as a method for linking TV programs and advertisements. As another proposed method, in a broadcast receiving device such as a television with a built-in function for connecting to the Internet, there is no one program table that can be received in advance by the device. However, some URL information is recorded, and information from the Internet based on the URL is taken in and displayed in parallel with the broadcast automatically or by user selection at the time when the corresponding broadcast starts ( Patent Document 1).

  However, the URL candidates that can be accessed first are limited to those that are selected by the broadcasting station and posted on the program guide. If the same access is considered for the program recorded by the DVR, the program guide itself is a past one. However, even if the program guide data is taken into the DVR, there is a concern that the URL posted in the program guide is not always the latest.

  Also, as a content recommendation proposing method, there is known a method for parameterizing recommended user profiles and user situations, scoring recommended content, and providing a user with a high score to the user . Since a recommendation score value changes according to a user's condition, the content according to a user's viewing condition can be recommended (patent document 2).

However, since the content is read from the tag of the recommended content, it is not considered which performer is the main one in the content. Further, there is no description of means for automatically updating the user preference file, and there is a concern that timely content cannot be provided to the user.

  Program production related information, teletext data, and caption data are acquired (S30), and the names of performers appearing in sentences and the number of appearances of role names are extracted (S31, S32), and a histogram is created (S33). From this, the main performer in the corresponding content is determined (S34). Next, performers with a high appearance frequency are picked up, converted into data as performer feature quantities of the corresponding contents, and stored in the program information recording unit 31 (S35). Here, as a method of counting the number of appearances of performers, in addition to directly counting the names and roles of performers, there is a title such as "~ san", "~ -sama", "~ -kun", "~ -chan", etc. The word that comes before is also extracted. In this case, the name is often different from a slightly accurate name, such as a nickname, and counting is performed by checking the similarity of character strings.

  In the embodiment of the present invention described above, since the advertisement reach does not decrease in real-time broadcasting, the main application target of the embodiment of the present invention is recorded in the DVR of the viewer's home. Package media such as a TV program or a secondary-use TV program broadcasted in the past and converted into a package media or a movie.

For example, even if it is a series drama, I like guests who appear only that time other than the main role, and when watching the broadcast, it is difficult to grasp the trend only by metadata, but if you use the embodiment of the present invention, the trend will be Extraction is possible.

  Further, since the broadcast receiving terminal only needs to transmit the title data, the burden on the device is small. Furthermore, since the broadcast receiving terminal obtains the user's personal information, the advertisement content corresponding to the user can be provided to the user based on the personal information. For example, as an example of a comprehensive toiletry company that changes advertising content according to the conditions of the user, if the individual can be identified, or the individual cannot be identified, but the user is identified with information such as gender and blood type It can be assumed that the advertisement content is changed according to the level of personal information that can be received, such as when it can be classified into a specific segment.

  Furthermore, according to the embodiment of the present invention described above, user preferences are extracted in real time in broadcast programs recorded by DVR and secondary usage contents of broadcasts, and information including advertisements is provided as a result. The mechanism can be realized.

  In addition, by creating advertising opportunities for secondary use of broadcasting, it is possible to provide a new marketing place for program sponsors by increasing advertisement reach in a composite manner and extracting user preference information. .
