Abstract
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.
Claims12
A method for encoding video data, said method comprising:
- 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.
A video encoder for encoding video data, said video encoder comprising:
- a lossless compression engine for compressing a block of the picture with lossless compression;
- a controller for measuring how far the particular block is from a center of the picture;
- and
- a lossy compression engine for compressing the blocks with lossy compression, wherein information loss is based on how far the particular block is from the center of the picture.
