Abstract

The invention relates to the technical field of digital televisions, and discloses a digital television program switchover method and device. The method includes the steps that a local side receives a program switchover instruction sent by a set top box, wherein the program switchover instruction indicates that a program is switched over to a target digital television program, and comprises a unique identification code of the target digital television program; the target digital television program is sent to the set top box through a fixed frequency point configured for the set top box in advance according to the unique identification code of the target digital television program. By means of the method, the digital television program switchover speed can be increased, and mosaics are avoided in the digital television program switchover process.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method and device for switching digital television programs. Background technique [0002] As a tool for disseminating media information, television plays an important role in people's lives. With the development of science and technology, the emergence of set-top boxes has enriched people's digital TV program life. People switch digital TV programs by operating the set-top box. [0003] In related technologies, digital TV programs are transmitted to a set-top box through a wired network, and when a user needs to switch digital TV programs, the set-top box switches programs, switching the current digital TV program to a target digital TV program selected by the user. When the target digital TV program and the current digital TV program are not on the same frequency point, the set-top box needs to switch the frequency point to the frequency point of the target digit...
