Abstract
A method for video processing includes determining, based on a first indication, whether a sub-block residual coding scheme is applied to residual of a current video block in a transform skip mode, the sub-block residual coding scheme splitting the residual of the current video block into multiple sub-blocks and a subset of the multiple sub-blocks have non-zero coefficients; determining, based on a second indication, a specific split pattern to be applied to the residual of the current video block, in response to the sub-block residual coding scheme being applied to the residual of the current video block; deriving, based on a third indication, the subset of the multiple sub-blocks which have non-zero coefficients; and performing a conversion on the residue of the current video block based on the determined subset of sub-blocks having non-zero coefficients.
