Multimedia distribution system with user behavior analyzer
View Patent ↗A multimedia distribution system or interactive digital television broadcast system (iDTV) comprising several content providers (CP: CP 1 , CP 2 ) broadcasting channels of video signals to a user (TV, STB) via a content selector (CS). The broadcast system comprises a user behavior analyzer (UBA) with quantitative behavior classifier (E(w)) able to analyze and to classify the quantitative consumption behavior of the user, and with a qualitative behavior classifier (F(x)) having as output classified user behaviors and prediction on future behaviors of the user. The classifiers are coupled to an opportunities selector (G(y)) that also receives information from additional content providers (ACP: ACP 1 , ACP 2 , ACP 3 ). Under control of the opportunities selector G(y), additional content, e.g. advertisements, meta-information, iTV applications, trailers, . . . is send to a multimedia data combiner (H(z)) whereby the additional content is published, e.g. by mixing or by an overlay operation on/ over the selected channel. As a result, the end-user gets his broadcast channel adapted with the content that was selected based on his consumption behavior. The role of the qualitative behavior classifier classifying and predicting the user consumption behaviors is different from the role of the opportunities selector defining, predicting and classifying windows of opportunities to publish/add content from additional content providers; and the interface (I 2 ) between them has an important role as business-to-business (B2B) interface.
1. A system comprising:
a user behavior analyzer to which an end-user can couple, said user behavior analyzer being adapted to analyze the behavior of said end-user with respect to a plurality of content providers adapted to transmit first multimedia data to said end-user via a first content selector controllable by said end-user to transmit the first multimedia data from a selected one of said content providers,
wherein said user behavior analyzer is adapted to transmit input controls signals to an opportunities selector, adapted (i) to receive additional input control signals from a plurality of additional content providers adapted to transmit second multimedia data to said end-user via a second content selector and (ii) to cause said second content selector to transmit to said end-user said second multimedia data from a selected one of said additional content providers; and
a multimedia data combiner adapted to combine said second multimedia data with the first multimedia data into a combined multimedia data signal and to transmit said combined multimedia data signal to said end-user.
2. The system according to claim 1 , wherein said opportunities selector is adapted to receive the additional input control signals that contain information about multimedia data available for transmission to said end user from said additional content providers.
3. The system according to claim 1 wherein:
said user behavior analyzer comprises:
a quantitative behavior classifier adapted to be coupled to said end-user and further adapted to analyze the quantitative behavior of said end-user, and
a qualitative behavior classifier to which said quantitative behavior classifier is coupled, the qualitative behavior classifier being adapted to classify the behavior of said end-user and to predict future behavior of said end-user,
wherein both said quantitative behavior classifier and said qualitative behavior classifier are adapted to provide control signals to be applied to said opportunities selector.
4. The system according to claim 3 , wherein said user behavior analyzer is adapted to analyze the end-user behavior comprising information about selection behaviors of said end-user.
5. The system according to claim 1 , wherein said opportunities selector is adapted to transmit information about the end-user's behavior to said additional content providers.
6. The system according to claim 1 , wherein at least one of said plurality of content providers is also one of the plurality of additional content providers.
7. The system according to claim 1 , wherein said user behavior analyzer is adapted to be coupled to said end-user via a set-top box located at the end-user's premises.
8. The system according to claim 7 , wherein said set-top box is adapted to be coupled to said first content selector to cause said first content selector to transmit to said end-user the first multimedia data from the selected one of said content providers to said.
