摘要
概述了MPEG-2解复用器的原理,介绍了一种采用高速通用DSP的MPEG-2解复用器的实现方法。本系统以TI的TMS320C5402为主处理器,配合小型CPLD的逻辑控制,系统的许多重要参数都可以根据需要,在不改变硬件的基础上进行随时在线调整,增强了系统的适应能力。
This paper introduces the theory of MPEG-2 transport demultiplexer and discusses an implementation of MPEG-2 transport demultiplexer using high-speed DSP. The system uses Digital Signal Processor TMS320C5402 of TI as main processor and CPLD as coprocessor. The hardware needs not to be changed, and many important parameters can be adjusted at any moment according to requirement. The adaptability of the system is enhanced.
