VIDEO DECODER WITH ENHANCED SAMPLE ADAPTIVE OFFSET

摘要

A decoder decodes video received in a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and a plurality of offset type characteristics. Each of the plurality of offset type characteristics is associated with a respective block of the video. A deblocking process deblocks the video to reduce artifacts proximate boundaries between the blocks of the video based upon deblocking information. A sample adaptive offset process classifies a pixel based upon the offset type characteristic associated with the respective block of the video and the deblocking information.
