This paper is based on the statistic for the appearance probability of all the modes in the whole sequence.Then for skip mode,a fast decision algorithm is proposed,which is to compare the RD cost of skip and inter 16×16 modes.For inter 8×8, a fast selection algorithm based on texture prediction is prsented.For intra 4×4,a simple algorithm is proposed.Finally,the result data show that the time is reduced by 38% on average while PSNR just reduces nearly 0.05 dB compared with JM8.6.
