Abstract
In one embodiment, an adaptive motion area process is performed to determine which macroblocks are to be intracoded. Adaptive motion change detection can efficiently reduce the large propagation error, including errors occurring in the motion area. An intercode distortion value and an intracode distortion value are calculated, as are an intercode bit rate and an intracode bit rate. Based on a comparison of the calculated intercode distortion value and the intracode distortion value, and on a comparison of the intercode bit rate and the intracode bit rate for each macroblock, a decision is made as to which predicted frame macroblocks are to be intracoded.
