Abstract

This disclosure relates generally to video coding and particularly to cross component level reconstruction. For example, a method is disclosed for processing video data which may include encoding a video block comprising a first transform block of a first color component and a second transform block of a second color component, wherein the first transform block and the second transform blocks are co-located blocks; encoding a first syntax element to signal whether a CCLR is applied to the first transform block, wherein, when CCLR is applied to the first transform block, a refinement process is required to be applied to the first transform block to obtain a refined first transform block on which an inverse transform is to be performed; and transmitting a bitstream comprising the video block and the first syntax element.
