Embodiment Construction

[0038] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as image 3 Shown is the first embodiment of the program switching method of the present invention. In this embodiment, there are different programs A, B, C, D. The viewer plays selected program B first. In this embodiment, the method of program switching is as follows:

[0040] S100) Play program B first. Programs A and C are adjacent programs of program B. When the user uses the up and down switching keys on the remote control or the operation panel, the user can switch from program B to program A or C; Data and audio data are filtered, and the filtered program B is decoded and played;

[0041] S200) While filtering, decoding and playing program B, perform real-time filtering on programs A and C: respectively select one channel of video data and one channel of audio data for the two programs to filter and update and save in real time;...

Abstract

The invention relates to a method and a system for quickly changing programs. The system for quickly changing programs comprises a data receiving module, a filtering module, a decoding module and a storage module, wherein the data receiving module is used for receiving original audio and video data, the filtering module is used for filtering audio and video data of a first program and a second program, the decoding module is used for decoding the filtered audio and video data to play, and the storage module is used for storing one channel of video data and one channel of audio data of the second program after filtering. The data receiving module, the filtering module and the decoding module are sequentially connected, and the storage module is connected with the filtering module and the decoding module. During playing of one program, other programs are filtered on the background, and one of channels of the video data and the audio data are selected to cache, so that cache data can be played during changing, and halt during program changing is shortened, black screen is avoided and good experience is provided for users.

Description

technical field [0001] The invention relates to the field of audio and video playback, and more specifically, relates to a method and system for quickly switching TV programs. Background technique [0002] With the development of TV broadcasting technology, digital TV is gradually popularized, and the role played by set-top boxes in TV broadcasting becomes more and more important. As the programs become more and more abundant and the content is more and more, the user puts forward higher requirements on the responsiveness and performance of the set-top box. [0003] When the existing set-top box switches programs, it obtains all audio and video data packets of the switching target program, and filters them for decoding and playing. However, the data volume of audio and video data packets of current TV programs is very large. Usually, a program includes multiple channels of video and multiple channels of audio data to meet the needs of different users for picture clarity and...
