Macroblock types of macroblocks of a video picture are encoded by adaptively employing codewords of codeword tables, based at least in part on one or more macroblock type related characteristics of one or more neighboring macroblocks of interest. The codewords may be variable in length. The one or more macroblock type characteristics may include a most common macroblock type characteristic of the neighboring macroblocks of interest. The adaptive employment of the codeword tables may be further based on a picture type of the picture of which the macroblocks are members. Decoding may be performed in an inverse manner.
