基于编码TMS320DM642的MPEG4编码器设计与实现。为满足视频通信中视频压缩的需要，在对MPEG4视频编码标准研究的基础上，提出了基于TMs32ODM642

DSP的MPEG4视频编码器的实现方案，并讨论了代码优化的方法，通过相关实验对提出的方案进行了编验证。实验结果表明，该方案实现了对标准QCIF格式图像序列的MPEG4编码，编码速率达到25 fps，满足了实时码的要求，图像质量满足

了预期效果。-TMS320DM642-based encoding of the MPEG4 Encoder Design and Implementation. Video communications in order to meet the needs of video compression, in the MPEG4 video coding standard based on the research, TMs32ODM642DSP based on the MPEG4 video encoder realization of the program and discuss ways to optimize the code, through the relevant experimental program conducted on the proposed the provision of authentication. Experimental results show that the program achieved the standard QCIF format MPEG4 image sequence coding, coding rate reached 25 fps, to meet the requirements of real-time code, the image quality to meet the desired effect.
