ABSTRACT:
The invention is related to methods and apparatus that can advantageously be used in a video encoder to improve picture quality, to improve the speed of encoding, and the like. One embodiment of the invention advantageously computes activity measures using an efficient L1-norm, which can advantageously be relatively quickly computed by selected microprocessors. Another embodiment of the invention advantageously allocates bits to macroblocks of a picture based at least in part on the motion activities of the macroblocks.
