Embodiment Construction

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0014] The present invention proposes a digital TV program recommendation method based on a set-top box, such as figure 1 Shown is a flow chart of the method of the present invention. This method adopts a fast I-frame search method for predicting by an adaptive filtering algorithm LMS. This algorithm makes full use of the structural characteristics of MPEG video stream and the statistical characteristics of I frame interval, and has obvious performance improvement...

Abstract

The invention discloses a set top box-based digital television program recommending system which is mainly operated on the basis of a personal program recommending system of a content filtering and cooperation filtering mixed mode. The set top box-based digital television program recommending system mainly comprises four functional modules: a user characteristic file module, a program characteristic file module, a cooperation filtering module and a recommendation module. Meanwhile, the invention also discloses a set top box-based digital television program recommending method. According to the invention, data accuracy and execution efficiency in design are high, and therefore, television programs according with the characteristics are recommended for a user. A cooperation filtering mechanism is introduced through a content-based recommendation mechanism, so that the recommended programs are more accordant with the wish of the user.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a set-top box-based digital TV program recommendation method and system. Background technique [0002] With the rapid development of digital TV technology, the cable digital TV system can reach the transmission capacity of 500-600 sets of programs under the current coding and modulation system. There will be a problem that TV users will not be able to pick and choose what interests them among so many programs. In order to completely solve this TV information "overload" problem, the electronic program guide must be intelligent. It can automatically recommend TV programs to the user in advance according to the user's interest, hobbies and rules, and it can also automatically track the change of the user's interest. The recommended TV programs are adjusted, which is the concept of the digital TV program recommendation system. [0003] In the field of TV program recommendation...
