为了保证MPEG-2 TS流解复用的质量,提出了一种基于DSP和FPGA共同实现MPEG-2 TS流解复用的设计方案。该系统实时处理,包含软件和硬件两个部分。试验证明,该设计能使DSP时钟稳定地工作在160M,即使图像处理速率高达80Mbps时也能够很好的保证图像的质量,达到了预期的设计目的。

In order to ensure the demultiplexing quality of MPEG-2 TS stream,it has brought in a system design for the demultiplexing based on DSP and FPGA in detail.This system belongs to real-time processing and includes both software and hardware.Multiple experiments have evidenced that this design can make the DSP clock works at 160M stably,and it can also ensure the image quality even the image processing rate is as high as 80Mbps,which meets the design goal so well.
