基于PES流的数字视频多节目复用器的设计和实现

Design and Implementation of Digital Video Multi-program Multiplexer Based on PES Streams

讨论了一种基于数字信号处理器 (DSP)的数字视频多节目复用器的设计和实现。该复用器的输入为多个节目基本流 (PES) ,输出为通过DSP多节目打包复用后的一路符合MPEG 2系统层标准的多节目传送流。同时还讨论了多节目复用中的难点———缓存设计。试验证明 。

The implementation and discipline of digital video multi program multiplexer based on DSP is discussed. The inputs of the multiplexer are program elementary streams, and the output is a multi program MPEG 2 transport stream. Buffer design of multi program multiplex is also discussed. The experimentation proved the design and structure of the multiplexer.
