摘要： A video coder may utilize large macroblocks having more than 16x16 pixels. Syntax for the large macroblocks may define whether a bitstream includes large macroblocks, such as superblocks having 64x64 pixels or bigblocks having 32x32 pixels. The syntax may be included in a slice header or a sequence parameter set. The large macroblocks may also be encoded according to a large macroblock syntax. The bitstream may further include syntax data that indicates a level value based on whether the bitstream includes any of the large macroblocks, for example, as a smallest-sized luminance prediction block. A decoder may use the level value to determine whether the decoder is capable of decoding the bitstream.
