Realization of H.263 Coder/Decoder System Using DSP

This paper describes how to realize coder/decoder system for ITU-T real-time video codec recommendation H.263 on TIs DSP TMS320C6201. On the basis of the research of H.263 proposal, several techniques for H.263 real-time codec impletation and transmission on the error prone channel have been proposed which significantly improve the performance of the video coder. According to the architecture of DSP, the hardware design and a series of optimizing schemes are presented.
