H.264 is a new video international standard.It becomes an important content of image communication research field.Based on high-performance Digital Signal Processor(DSP)to implement H.264 video Encoder is one of most efficient methods,which also helps to promote the application of H.264.DM64X produced by TI Company have strong capacity of parallel processing and signal processing that it is considered to be just the ideal platform.The key points to realize video encoding in DSP.The whole system scheme based on DM642 is given.H.264 is realized and the performance of this system is given.The decoding speed has achieved the real-time effect,the image subjective quality is good,not obvious block effect,the code rate is also quite low.
