ABSTRACT:
A technique for encoding macroblocks of a frame is provided which includes switching a coding decision for a macroblock from a non-intra decision to a skip macroblock decision when the absolute prediction error for the macroblock is less than a prediction error threshold and the magnitude of the motion vector for the at least one macroblock is less than a motion vector threshold. In one embodiment, the prediction error threshold is multiple programmable prediction error thresholds, which are for comparison with the absolute luminance and chrominance summation components and the maximum luminance and chrominance difference values. The motion vector threshold may be a preset value when the macroblock is to be predictive coded, and may be the magnitude of the motion vector of the previous macroblock when the macroblock is to be bi-directionally encoded.
