摘要
以高清晰度电视传送复用器的实时实现为目的，在概述ＭＰＥＧ－２传送层语法规范的基础上，给出了传送复用器实现的设计方案和实现技术．传送复用器的功能是将音频、视频及辅助数据按ＭＰＥＧ－２传送层语法规范打成ＴＳ包并送往信道．文中提出的方法是用ＤＳＰ查询复用器各输入缓冲区的状态，根据各缓冲区的状态读入数据，完成音、视频及辅助数据的ＴＳ打包，并保证各ＴＳ包交织均匀。
The real time implementation designing method and the implementation technology of an HDTV transport multiplexer were given based on the discussion about MPEG 2 transport layer syntax. The function of a transport multiplexer was to package the audio, video and auxiliary data to TS packets according to MPEG 2 transport layer syntax, and to transmit those packets to a channel. The main idea of transport multiplexer designing method was checking the status of every input buffers of a multiplexer by using a DSP and packaging the data read from buffers to the TS packets according to the buffer status. Each kind of the TS packets can be interlaced equally by using this method. The implementation result was also given.
