Abstract

To decrease the computational complexity of adaptive inter-layer prediction and improve the encoding efficiency in spatial and temporal scalable video coding, a mode decision algorithm is proposed by exploiting the part of used modes in the co-located reference macroblock(s) for Hierarchical-B pictures of all layers. This scheme generates a reduced dynamic candidate list for the current macroblock according to the statistical information derived from the co-located reference macroblocks in their present temporal level. The experimental results show that this algorithm compresses approximately 29% in encoding time with the negligible loss in PSNR and slightly increasing in bit rate.
