摘要： 描述了一种新的基于PC的MPEG-2&DVB传输流TS（Transport Stream）分析系统的软件实现，该系统可以实现对MPEG系统的测试和诊断，并能对视频节目进行分析。由于采用了多线程的调度算法和层次化的设计结构，能够实现传输流的简单实时分析，显示码流的基本信息，即码率、每个节目的PID等；并能对传输流进行更深入、更复杂的离线分析，能给出传输流的PSI表信息、PCR信息、DVB信息，检测传输流中的部分错误。

Abstract: This paper presents the implementation of a new test and analysis platform that the authors have developed for testing transport stream of HDTV system. This platform can exchange the data with the tested moulds in high speed though PCI bus. With the using of the multi-thread scheduling algorithm in the structure, this platform can carry out simple real-time analysis of transport stream. In some cases, this platform can also be used to deal with the more complex and sophisticated off-line transport stream analysis. The platform allows real time diagnose, which can't be implemented by traditional video testing tools, of HDTV transport stream. The platform also includes DVB. This platform has been applied in video encoder subproject of China's HDTV project.
