    摘要: For processing, e.g. encoding or decoding, a video stream, a type of a current macroblock unit is determined. The type indicates portions of corresponding macroblock parameter sets necessary for processing the current macroblock unit. The corresponding macroblock parameters are mapping to a dependent set of macroblock units of the current macroblock unit. The current macroblock unit is processed if a local buffer already stores the portions of the corresponding macroblock parameter sets. If data of the portions of the corresponding macroblock parameter sets that are not available in the local buffer, the data are copied from a memory circuit into the local buffer for processing the macroblock unit.
