Playing method, device and system based on multi-channel television audio data

Abstract

The invention provides a multichannel-based television audio data playing method, device and system, wherein the method comprises the following steps of: setting a first linked list, wherein the first linked list is used for maintaining audio data to be played, the audio data to be played is audio data from a first television channel, the audio data to be played includes carried information, and the first linked list includes multiple first nodes for storing the carried information; when the fact that the first linked list is not empty is judged, uninstalling the nodes of unit data from the first linked list, and configuring the uninstalled nodes; playing the audio data to be played corresponding to the nodes, wherein the configuration of the nodes is completed; and uninstalling and releasing the residual nodes in the first linked list when the fact that the first television channel is switched to a second television channel is detected. By means of the multichannel-based television audio data playing method, device and system disclosed by the invention, audio data of all television channels can be played sequentially, smoothly and stably in real time.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a playback method based on multi-channel TV audio data, a playback device based on multi-channel TV audio data and a playback system based on multi-channel TV audio data. Background technique [0002] In the development process of a digital TV SoC (System-on-a-Chip, System-on-Chip) chip, audio post-processing is an important function to be realized. If the performance of this function is insufficient, there will be a series of problems when the TV product using this SoC plays audio data, such as the moment of TV channel switching, such as when switching from ATV channel to HDMI channel, the audio reading device still needs to Read the incoming audio data of the previous channel before starting to read the incoming audio of the new channel. In this way, the remaining audio data of the previous channel will be played first, and then the audio data of the newl...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a playback method, device and system based on multi-channel TV audio data to solve the problem of playing the residual audio data of the previous channel for a while and then playing the audio data of the newly switched channel when switching channels. At the same time, the implementation of the present invention can make the audio data of the TV channel in real time, orderly, smooth and stable play
