Abstract

In order to speedup the encoding processing of Scalable Video Coding (SVC), a CBP (Coded Block Pattern)-based fast mode decision algorithm is proposed in the paper. The CBP value is the syntax used at each Macroblock (MB) header to indicate whether an MB contains residualinformation or not. By the CBP values and MB modes of adjacent MB in Enhancement Layer (EL) and the co-located Base Layer (BL) MB mode, the proposed algorithm can exclude the invalid modes for the mode prediction of the current MB in EL. Experimental results show that the proposed algorithm achieves more than 76% EL Motion Estimation (ME) time-saving with ignorable PSNR degradation and bit increase when compared to JSVM 9.12.
