Method and system for acceleration of lossy video encoding owing to adaptive discarding poor-informative macroblocks

摘要

Disclosed herein is a method for acceleration of video encoding owing to adaptive discarding macroblocks is based on objective regularities between numerical characteristics used on successive stages of lossy encoding process. This method enables to avoid a large amount of computation and transformation being not necessary due to the fact that their results would be reduced to zero on stage of quantization. The early revelation of these regularities and adaptive control of discarding technique produce a very effective encoding scheme that can be used in the encoding systems that are aimed to extremely fast processing of video streams, in particular, in multi-channel codecs.
