Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a digital TV program based on Bayesian algorithm for the defect that the existing TV program recommendation method only counts the viewing behavior of the user and ignores the broadcasting behavior of the TV station, resulting in inaccurate recommendation results. Recommended methods and systems

Embodiment Construction

[0093] figure 1 It is a schematic structural diagram of a digital TV network 100 according to a preferred embodiment of the present invention. like figure 1 As shown, the digital TV network 100 includes a digital TV program recommendation system 102, a plurality of digital TV terminals 104, 106 and 108, and a broadband metropolitan area network 110, wherein a plurality of digital TV terminals 104, 106 and 108 pass through the broadband metropolitan area network 110 communicates with the digital television program recommendation system 102 .

[0094] The digital TV terminals 104 and 106 are connected to the broadband metropolitan area network 110 through two-way set-top boxes. The two-way set-top box can be used not only to receive TV programs through the broadband MAN 110, but also to send the statistical user viewing records to the digital TV program recommendation system 102 through the broadband MAN 110. Unlike the digital TV terminals 104 and 106 , the digital TV term...

Abstract

The invention relates to television program recommendation. The invention provides a method and a system for recommending digital television program based on bayesian algorithm aiming that existing television program recommendation method only statistics user's viewing behavior but ignores playing behavior of television station. The method includes: collecting user's viewing recorder; analysing user's viewing recorder and obtaining user's viewing action parameter. The method also includes: obtaining television station playing action parameter according with viewing behavior parameter; predicting user's viewing probability to waiting-played television program according with viewing action parameter and playing action, and recommending television program to user thereof. The invention also provides a recommendation system corresponding to the method. Because combining the user's viewing action parameter and television playing action parameter when predicting user viewing special program, a recommendation result obtained by the television program recommendation is more accurately and reflects real user's viewing taste.

Description

technical field [0001] The present invention relates to TV program recommendation technology, more specifically, to a digital TV program recommendation method and system based on Bayesian algorithm. Background technique [0002] Today's world is in the midst of a wave of digitalization, and so is broadcast television. Major developed countries in Europe and the United States have set the time for the full digitalization of radio and television around 2010, and my country also plans to fully realize digitalization in 2015. By the end of 2006, China's digital TV users had reached 12 million, and, according to CCID Consulting's forecast, by 2007, the global digital TV users will reach 630 million. [0003] One of the changes brought about by the digitization of TV is the great abundance of TV programs. According to the current video encoding method of MPEG2, the cable TV system will be able to transmit 500 sets of standard-definition digital TV programs. If advanced coding f...
