Fast mode decision algorithm for H.264/Svc

Abstract

H.264/AVC extension is H.264/SVC which is applicable for environment that demands video streaming. This paper presents an algorithm to reduce computation complexity and maintain coding efficiency by determining the mode quickly. Our algorithm terminates mode search by a probability model for both intra-mode and inter-mode of lower level and higher level layers in a Macro Block (MB). The estimated of Rate Distortion Cost (RDC) for modes among layers is used to determine best mode of each MB. This algorithm achieves about 26.9% of the encoding time when compared with JSVM reference software with minimal degradation in PSNR.
