Description

  The present invention relates to a content viewer classification information generation system and content viewer classification information generation that create content viewing information including information that classifies content viewers using a digital watermark embedded in the audio data of the content. It relates to a method and a program.

Content such as video and audio is provided to viewers through broadcast programs such as TV programs and radio programs, distribution of moving images via the Internet, DVDs, etc., but how much the content is viewed by content providers. It is very important to check the viewing situation.
On the other hand, as a means for preventing unauthorized use of content, a technique for embedding a digital watermark in audio data of the content has been developed, and the viewing status of the content is confirmed using the digital watermark embedded in the content. A system has also been proposed.
For example, in Japanese Patent Laid-Open No. 2009-268036 (Patent Document 1), a sound watermark superimposing apparatus uses a well-known sound watermark technique to add code or the like for specifying broadcast content to audio data of the broadcast content. Audio data is superimposed and superimposed, the broadcast station transmits broadcast data including this audio data, and the TV sensor collects the sound emitted from the speaker of the TV device with a microphone and extracts the acoustic watermark included in the audio Then, the data is converted into electronic data (code data), date / time information and the like are added to the code data and output to the counting device, and the counting device counts the code data sent from the TV sensor, and based on this counting data Thus, a viewing confirmation system that can analyze in detail the confirmation of the viewing situation and the viewing rate has been disclosed.
Japanese Patent Laid-Open No. 2010-124036 (Patent Document 2) embeds an electronic watermark in which content information and notification destination information are repeatedly described in the content, reads the electronic watermark in the electronic watermark at the time of reproduction, and the contents According to the above, the playback information is notified to the viewing result management device as a notification destination, and the viewing result management device counts the number of views of the content provided by the distributor specified by the distributor information in the digital watermark. A digital content viewing performance management system is disclosed.

However, in the viewing confirmation system disclosed in Patent Document 1, a television sensor picks up sound emitted from a speaker of a television device with a microphone, extracts an acoustic watermark included in the sound, and converts it into electronic data (code data). Therefore, there is a problem that it cannot be applied to a case where a content distributed without producing sound from a speaker is reproduced in a portable terminal device or the like (in this case, sound is reproduced with an earphone or the like).
In addition, in this viewing confirmation system, only viewing status and viewing rate are confirmed, so information that classifies viewers by viewing time etc., for example, only a good viewer who has played all the distributed content or only a part of it is played. There is a problem that it is impossible to obtain information such as an unsatisfactory viewer.
Next, in the content viewing record management system of Patent Document 2, it is not clear which data in the content has been embedded with the digital watermark, and when the content is reproduced, the digital watermark in the digital watermark is read and reproduced in accordance with the content. Since the information is notified, there is a problem that only the information on whether or not the content has been reproduced is managed, and detailed reproduction information such as how much the viewer has reproduced the content cannot be obtained.

In FIG. 9, “viewer classification information” is generated by the viewer classification information generation units 14 and 44, and is the same as the viewer classification information shown in FIG.
The “distributed advertisement ID” specifies the content of the advertisement distributed when the content is reproduced by the content reproducing units 12 and 32. In the “previous”, the viewer classification information generating units 14 and 44 are classified by the viewer classification. This is a distribution advertisement ID that identifies the content of the advertisement distributed to each viewer before generating information, and “next time” indicates each viewing after the viewer classification information generation units 14 and 44 generate the viewer classification information. This is a distribution advertisement ID that specifies the content of an advertisement to be distributed to a person.
The advertisement information creation units 17 and 47 reproduce the content next time, that is, the next time, based on the viewer classification information stored in the storage units 16 and 46 for the viewer specified by the viewer ID. In this case, a distribution advertisement ID that specifies an advertisement to be distributed is created as advertisement information.
Specifically, as shown in FIG. 9, for the viewers identified by the viewer IDs “0001”, “0002”, and “0100”, the advertisements distributed last time (before the generation of viewer classification information) are distributed. When the advertisement ID is “k100”, “k300”, or “k200”, and the viewer classification information of each viewer is “A”, “C”, or “B”, it will be delivered to each viewer next time The advertisements to be are advertisements specified by the distribution advertisement IDs “k300”, “k200”, and “k300”, respectively.
In other words, an advertisement (an advertisement with distribution advertisement ID “k300”) distributed to a low-credibility viewer of viewer classification information C is distributed to viewers with high and medium credibility of viewer classification information A and B. Then, an advertisement (an advertisement with the distribution advertisement ID “k200”) distributed to the viewer with the low reliability of the viewer classification information B is distributed to the viewer with the low reliability of the viewer classification information C.
In this way, by changing the content of the advertisement delivered to each viewer next time to the one delivered last time, it gives viewers freshness, lengthens the playback time (viewing time) of the content, and uses the content. Can be enlarged.

In addition, when the viewer classification information generated by the viewer classification information generation units 14 and 44 is content type information as shown in FIG. 6, the advertisement information creation units 17 and 47 specify the viewing specified by the viewer ID. Based on the content type information that is the viewer classification information stored in the storage units 16 and 46, a distribution advertisement ID that identifies an advertisement with the content corresponding to the content type information is created as advertisement information.
As a result, it is possible to distribute an advertisement having contents corresponding to the viewer's hobbies and preferences to the viewer.
