System, method, and apparatus for decoding flexibility ordered macroblocks

摘要

Presented herein is a system and method for decoding flexibly ordered macroblocks. Slice groups are received, wherein the slice groups comprise non-contiguous macroblocks with respect to raster scan order. Each macroblock is associated with a particular context which serially provides each macroblock to a processor for decoding. The decoder selectively decodes the macroblock from the first context or second context, depending on which context includes the next macroblock in raster scan order.
