Many new technologies,including integral DCT,multiform quantization methods selection and precise intra-frame prediction,are adopted in H.264 to improve the image quality.However,this also increase the computation complexity.Using MMX/SSE/SSE2 to optimize the key algorithms in H.264 decoder can improve the efficiency greatly without degrading the image quality.
