CODED BLOCK PATTERN ENCODING/DECODING WITH SPATIAL PREDICTION

摘要

A video decoding system and video decoding method are disclosed for decoding block parameters which were compressed by exploiting the correlation between chrominance and luminance blocks in each macroblock.
Coded block parameters were used to code image blocks of image samples into structures called macroblocks. Coded block pattern for chrominance and luminance are combined into a single parameter for the macroblock and jointly coded with a single variable length code. Spatial coherence of coded block patterns can be further exploited by computing spatially predicted coded block pattern parameters.
