| Abstract: | In this paper,the principle,function and implementation of two important parts of the source decoder,namely,the demultiplexer and the video display-buffer that are implemented by DSP TMS320C80s,will be presented.In addition,the process of adjusting and some innovative testing function of these two boards will also be discussed. The demultiplexer and the video decoder conform to the system standard(ISO/IEC 13818 1) and the video standard (ISO/IEC 13818 2) of MPEG 2. |
