METHODS AND APPARATUS FOR VIDEO CODING AND DECODING WITH REDUCED BIT-DEPTH UPDATE MODE AND REDUCED CHROMA SAMPLING UPDATE MODE

摘要

There is provided a method and apparatus for video coding and decoding in a reduced bit depth update mode and a reduced chroma sampling update mode. The apparatus includes means for encoding at least one portion of the picture using at least one of a reduced bit depth update mode and a reduced chroma sampling update mode that reduces at least one of bit depth and chroma sampling of the residual signal corresponding to the portion, Encoder 200 as shown in FIG.
