The Optimization of H. 264 Decoder on Windows Mobiles
Windows Mobile平台上H．264解码器的优化

The emerging of a new video compressing code H.264,which provides a better support for wireless video-transmitting,further guarantees the transmitting the enhanced picture in low bit-rate.But due to the high complexity of computation,it is a hotspot as to how to put the new decoder into applies.This paper discusses in detail several ways of optimization of h.264 decoder on windows mobiles.According to the characteristics of the decoder and the PLA270 center processor,we suggest a way of optimization using C and WMMX.It is demonstrated after experiments that the optimized decoder could meet the basic requirements of in-time surveillance.
