基于TS流解复用的音视频同步新实现方法

Novel Implementation of Audio and Video Synchronization based on TS Stream Demultiplexing

介绍数字电视TS码流的基本结构,分析了音视频同步的基本方法,在此基础上提出一种新的音视频同步的方法,并且介绍了如何来实现此方法.在实际的解码过程中,根据解码不同步时的具体情况,提出了跳帧和重复帧的具体方法,来实现音视频的同步.

This paper introduce the base syntax structure and composing of MPEG - 2 Transport stream, and analysis the base theory of audio and video synchronization. A new method was put forward based on it, and the realization of it was also introduced. The way of frame-skip and frame-repeat was taken when the audio and video is asynchronism in decoding process.
