基于DSP的HDTV实时码流合成器实现

Implementation of Real-time Stream Synthesizer of HDTV Based on DSP

论述了MPEG2码流系统级的语法以及码流合成应作的语法处理。介绍了采用DSP为核心 ,配合EPLD通过软件实现的实时码流合成器设计 ,并给出了实现框图。采用高可靠性设计 ,成功地实现了国内第一个实时条状码流合成器。经过现场实际应用证明 ,其具有很高的可靠性和灵活性。

The system level semantic definition of MPEG2 and some semantic processing for stream synthesize are introduced. The stream synthesizer used a DSP as system kernel and used tow EPLDs as slave control units are described and the system diagram is offered. The first slice stream synthesizer in China is realized by the high reliable technology. The long time field application shows that it has high reliability and flexibility.
