基于DirectShow的MPEG-2流媒体多路播放与实时存储系统设计与实现

Design and Implementation of MPEG-2 Streaming Media Multichannel Playing and Real Time Data Saving System Based on DirectShow

DirectShow是基于COM的多媒体应用开发技术。介绍了DirectShow系统的体系结构,重点讨论了本系统中源Filter和解复用Filter的设计方案,以及不同MPEG-2传送流之间动态切换播放的关键技术,设计并实现了网络MPEG-2流媒体的多路播放系统,以及VOB格式的实时数据存储模式。

DirectShow is a kind of technology for developing multimedia based on COM. This paper introduces the architecture of DirectShow, and puts emphasis upon the developing method of source filter and demultiplexer filter, and the key technology of dynamic switching playing for different MPEG-2 TS. Then the paper analyzes the design and implementation of system of MPEG-2 Streaming Media multichannel playing and the mode of real time data saving in VOB for.
