- We propose a fast inter-mode prediction and decision algorithm based on a contextual information for the P-slices in the H.264/AVC video standard. In the H.264/AVC standard, motion estimation part is composed of intra-modes and intermodes. In the inter-mode prediction, 7 block types exist to get the best coding gain based on rate-distortion (R-D) optimization. This scheme gives rise to an exhaustive computation (search) in the coding procedure. To overcome this computational exhaustiveness, an improved technique is suggested by using the contextual prediction. Also, we will verify the performance of the proposed scheme through the analysis of some experimental results. ©2006 IEEE.
