Title:
VIDEO ENCODING AND DECODING USING ADAPTIVE COLOR TRANSFORM
Document Type and Number:
WIPO Patent Application WO/2021/145691
Kind Code:
A1
Abstract:
The present disclosure relates to video encoding and decoding using adaptive color transform on a residual signal. According to one aspect of the present disclosure, the maximum memory size required for adaptive color transform is limited by: controlling whether to allow color space conversion on a sequence level according to a syntax element indicating the maximum conversion size allowed for a sequence of pictures; or controlling whether to apply color space conversion on a block level according to the size of a coding block.
