US Patent 11570458 Indication of two-step cross-component prediction mode

A method for video bitstream processing includes generating a prediction block for a first video block of a video related to a first component, where the prediction block is selectively generated according to a criterion by applying a two-step cross-component prediction mode (TSCPM), and performing a conversion between the first video block and a bitstream representation of the video using the prediction block, wherein a first field in the bitstream representation corresponds to the TSCPM.
