Title:
SIGNALING AND SYNTAX FOR IN-LOOP RESHAPING INFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/182219
Kind Code:
A1
Abstract:
A method for video processing is provided to include: performing a conversion between a current video block of a video and a coded representation of current video block, wherein the conversion uses a coding mode in which the current video block is constructed based on a first domain and a second domain and/or chroma residue is scaled in a luma-dependent manner, and wherein information used for the coding mode is signaled in a parameter set that is different from a sequence parameter set (SPS), a video parameter set (VPS), a picture parameter set (PPS), or an adaptation parameter set (APS) used for carrying adaptive loop filtering (ALF) parameters.
