Improved video coding using adaptive coding of block parameters for coded/uncoded blocks |
摘要 |
<p>A method of entropy coding a luminance coded block pattern value for a macroblock of a video image includes associating the luminance coded block pattern value with an entropy code according to a coding mode, and adaptively selecting (132) the coding mode from among plural coding modes (134, 136) based upon a chrominance coded block pattern value for the macroblock. The adaptively selecting (132) may include: selecting (134) a first coding mode when data for luminance blocks of the macroblock is likely to be coded; and selecting (136) a second coding mode when data for the luminance blocks is not likely to be coded. <IMAGE></p> |
