Description: 在MPEG-2系统中，信息复合/分离的过程称为系统复接/分接，由视频，音频的ES流和辅助数据复接生成的用于实际传输的标准信息流称为MPEG-2传送流（TS：TransportStream）。 据传输媒体的质量不同，MPEG-2中定义了两种复合信息流：传送流（TS）和节目流（PS：ProgramStream）TS流与PS流的区别在于TS流的包结构是固定长度的，而PS流的包结构是可变长度的。这个文档讲的是PS流的标准。(In the MPEG-2 system, the process of information combining / splitting is referred to as system multiplexing / tap. The standard information stream for actual transmission generated by multiplexing video and audio ES streams and auxiliary data is called MPEG-2 transmission Stream (TS: TransportStream). According to the different quality of transmission media, MPEG-2 defines two kinds of composite information flow: Transport Stream (TS) and Program Stream (PS: Program Stream) The difference between TS stream and PS stream is that the packet structure of TS stream is a fixed length, The PS stream packet structure is variable length. This document is about the standard PS stream.)
