摘要
文章介绍了一种在 TMSC60 0 0系列 DSP芯片上实现 MPEG-1标准的音视频数据合成的软件实现方法 ,详述了音视频信号的同步与实时播放的实现要点 ,同时介绍其相关应用。该实现方法可以满足在嵌入式网络多媒体监控系统中实时编解码并显示的应用需求 。
A method of compounding MPEG-1 audio and video streams based on the digital signal processors(DSPs) of TMSC6000 Series by software compiling is introduced,and several keys to achieving synchronization and real-time play of audio and video signals are analyzed in detail.The correlative application of the method in the embedded multi-media surveillance system is described,and the result is satisfying. The presented method can also be used in other embedded audio and video coding systems.
