基于DirectShow的卫星电视多路节目播放技术

The Technology of Playing Satellite multi-TV Programs Based on DirectShow

首先对MPEG-2系统层协议进行剖析,然后介绍了DirectShow的应用领域和技术要点,最后提出了一种基于DirectShow的多路视音频播放技术,并给出了主要模块的设计方案,以及DirectShow链路死锁问题的解决方法。这种方法应用于多路电视节目的实时播放和节目素材的收集与整理之中,较传统的单路节目播放和采集节约了硬件成本提高了工作效率。

At first analyses the MPEG-2 system layer protocol then introduces the fields and major technology points of DirectShow applications.At last a method of playing multi-video based on DirectShow and project of major module,and the method solved dead- lock of DirectShow Filter Chain are given.This method applies to the playing of multi-TV programs and the collection of multimedia program material,and it economizes the hardware resources and improves the efficiency.
