Abstract
Block-level statistical measures are generated and then used to generate macroblock-level statistical measures, which are in turn used to determine how to encode the macroblocks of the image. In a preferred embodiment, a macroblock-level intra-SAD measure is generated by summing four block-level intra-SAD measures generated from the four blocks of the macroblock. The macroblock-level intra-SAD measure is then used to determine whether to encode the macroblock using intraframe encoding or interframe encoding. Basing macroblock-level statistics on block-level measures can provide a more accurate prediction as to how the macroblock would be encoded using intraframe encoding techniques.
