H.264是新一代的视频压缩标准。本文首先研究了该标准的主要内容，然后简要介绍了DSP TMS320DM642的出色性能及

其视频驱动程序的实现，最后讨论了H.264编码在DSP TMS320DM642上的优化与实现。

-H.264 is the next generation of video compression standards. This article initially on the main elements of the standard, and then briefly introduced the excellent performance DSP TMS320DM642 video driver and the realization of the final discussion of the H.264 encoding on DSP TMS320DM642 in the optimization and implementation.
