Title:
画像データの復号化方法およびそのためのプログラムを記録したコンピュータ読み取り可能媒体
Document Type and Number:
Japanese Patent JP4673758
Kind Code:
B2
Abstract:
A video encoding and decoding method are disclosed for encoding and decoding block parameters wherein the correlation between chrominance and luminance blocks in each macroblock is exploited.
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.
