Method for generating electronic program guide of digital television set

Abstract

The invention relates to a method for generating electronic program guide of digital TV, including inputting a program message containing the electronic program guide in a terminal machine; storing the program message into an electronic program guide message database, arranging and modifying the playing time of program messages in electronic program guide in the database and using these arranged messages as an index and storing the index into the database; the electronic program guide playing system automatically inquires the arrangement message of electronic program guides in the database, and automatically draw s the corresponding electronic program guide messages according to the playing time in the arrangement message and packages the program messages in the electronic program guides into data segments of digital video broadcast, namely service message list according to the standards of digital video broadcast and motion picture expert group, etc; it packages these data segments into a code stream composed of continuous 1888-byte data packet, conforming to (MPEG-2) standard; it generates the code stream into data stream and makes circular playing and displaying. It provides a complete set of solutions to make, arrange, examine and play electronic program guides.

Description

technical field [0001] The invention belongs to the technical field of digital television, in particular to a method for generating a digital television electronic program guide, which is used in a digital video broadcasting (DVB) system. Background technique [0002] Due to the rapid development of digital TV, digital TV will break the traditional completely passive TV model, and the demand for human-computer interaction will increase with the development of application services. Electronic Program Guide (EPG) is a basic function of a digital TV set-top box. At present, there are not many value-added services based on digital TV in China. In addition to adding and descrambling (CA) to digital TV programs, set-top box (STB) users are basically still in the stage of watching digital TV programs. Although the electronic program guide is equipped as a basic service, many operators only rely on various front-end equipment, such as multiplexers, modulators and their network mana...

AI Technical Summary

Problems solved by technology

Although some operators are aware of the importance of EPG in the entire digital front-end and STB applications, and provide independent EPGs, these existing EPGs do not have a complete set of technical implementation solutions, and the existing technologies only partially include the front-end production, arrangement or data organization, encapsulation, transmission or back-end (STB) reception, display or binding between EPG and other digital TV value-added services, or the connection relationship played by EPG in the entire digital front-end system

Due to the incompleteness of EPG implementation technology, there is no set of relevant technical standards in China
