System and method for improving video data compression by varying quantization bits based on region within picture

摘要

Presented herein is a system and method for improving video data compression by varying quantization bits based on a region within picture. In one embodiment, there is presented a method for encoding video data. The method comprises dividing a picture into a plurality of blocks; compressing a particular one of the plurality of blocks with lossless compression; measuring how far the particular block is from a center of the picture; and compressing the particular one of the blocks with lossy compression, wherein information loss is based on how far the particular block is from the center of the picture.
