The H.264/AVC standard achieves a much higher compression performance than the present standards of MPEG-1/2/4 and H.261/263. To achieve the highest coding efficiency, the H.264 encoder employs rate-distortion optimization (RDO) techniques to produce the best coding results in terms of both bit-rate.....
