日益增长的广播电视数字业务的需求,使得作为数字电视广播前端关键设备之一的再复用器成为当前研究与开发的热点。而对多节目传输流的解多工复用是再复用器中的一项重要技术,其效果的好坏将直接影响到再复用器的质量。本次设计在对数字电视传输流复用和解复用技术以及MPEG-2相关标准了解的基础上,利用PC机进行完备的节目专用信息滤波以及解复用流程的实现。
The demand of the growing digital service of radio and television has made the re-multiplexer, one of the key equipments in the front of digital TV broadcasting, become the hot spot in the research and development. However, demultiplexing the multi-program transport stream is an important technique in the multiplexer. The quality of the multiplexer will have a direct impact on the quality of the multiplexer. Based on the understanding of multiplexed and demultiplexed technologies of digital television transport stream and MPEG-2 related standard, this design uses PC to complete the program-specific information filtering and the realization of demultiplexing process.
