  Abstract

For the improvement of coding efficiency. the H.264 standard uses new coding tools such as VBS, 1/4-pel accurate ME, multiple references, intra prediction, loop filter, etc Using these coding tools, H.264 has achieved significant improvements from rate-distortion point of view compared to existing standards However, the encoder complexity is greatly increased due to these coding tools We focus on the complexity reduction method of MB mode selection Among all modes which can be selected, 8×8 and intra 4×4 mode have higher complexity than the others So we propose the methods for reduction of the 8×8 and intra 4×4 mode complexity by using information of other modes With relatively low complexity. Simulation results show that the proposed methods save up to 54.6% of total encoding time while keeping the average decrease about O.O12dB in PSNR.
