Claim 16:
17. An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
perform a conversion between a current video block of a second color component of a video and a bitstream of the video using a cross-component prediction with multiple-parameter model (CCPMPM) in which samples of the current video block are predictively coded in the bitstream using a linear combination of samples of a first color component multiplied by linear coefficients and/or one or more offsets;
wherein the bitstream conforms to a format rule; and
wherein the linear coefficients of the CCPMPM are determined using a first rule; and
wherein the samples of the first color component are determined using a second rule.
