Abstract

The embodiment of the invention discloses a program content broadcasting method which comprises the following steps of: when a program content update request sent by a set-top box is received, judging whether the program content needs updating; if so, writing the program content to be updated into a program file; encapsulating the program file into a program data packet; and broadcasting the program data packet to the set-top box. Through the invention, the set-top box does not need to analyze a complicated PSI / SI (program specific information / service information) table in the front end code stream, directly analyzes the data packet formed by encapsulating the file carrying the program content, and displays the program content to a user, thereby improving the working efficiency and transmission reliability of the system.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a method for distributing program list content and a digital television front end. Background technique [0002] Digital TV is an end-to-end system that digitally processes signals from program acquisition, program production and program transmission to the user end. Broadcast and interactive digital TV based on DVB technology standard adopts advanced user management technology to perfect the quality and quantity of program content and bring users more program choices and better program quality effects. Digital TV system can Transmission of multiple services, such as high-definition television, standard-definition television, interactive television and data services. Compared with analog TV, digital TV has the advantages of high image and sound quality, and large program capacity (more than 10 times the program capacity of analog TV transmission channels). [0003] In the prio...
