Abstract:
1. In a video decoder, a method of reconstructing one or more video images in a video sequence, the method comprising: decoding macroblock type information for a macroblock, first coded block pattern information for plural luminance blocks of the macroblock, and second coded block pattern information for plural chrominance blocks of the macroblock, wherein the first coded block pattern information indicates whether any of the plural luminance blocks have transform coefficient data in a bitstream, wherein the second coded block pattern information indicates whether any of the plural chrominance blocks have transform coefficient data in the bitstream, wherein the macroblock has a macroblock type indicated at least in part by the macroblock type information, and wherein the decoding comprises: using the macroblock type information, the first coded block pattern information, and the second coded block pattern information during reconstruction of the one or more video images.
