Patent ID: 8644392

Claim:
A video decoder, comprising: a processor operative to: store macroblock adaptive frame-field (MBAFF) coding parameters of a row of previously decoded neighboring MBAFF macroblock pairs in a data buffer in a MBAFF coding mode in which a size of the data buffer is doubled in comparison to a non-MBAFF coding mode, each macroblock pair comprising a first macroblock and a second macroblock, the first macroblock comprising odd numbered horizontal lines of the first and second macroblocks, and the second macroblock comprising even numbered horizontal lines of the first and second macroblocks; store control parameters for each of the macroblock pairs in the data buffer; reconstruct coding parameters for a current macroblock pair using availability information associated with the neighboring macroblock pairs; and store the reconstructed coding parameters for the current macroblock pair in the data buffer.
