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,最后给出了实现结果
Based on the overview of the syntax of the MPEG-2 transport layer, the design scheme and implementation technology of the transport multiplexer are given for the purpose of real-time implementation of high-definition television transmission multiplexer. The function of transmitting the multiplexer is to pack the audio, video and auxiliary data into TS packets according to the MPEG-2 transport layer syntax and send them to the channel. The method proposed in this paper is to use DSP to query the status of each input buffer of the multiplexer, read the data according to the status of each buffer, complete the TS packing of audio, video and auxiliary data, and guarantee the uniform interlacing of each TS packet. Finally, To achieve the results
