1. A method of processing video data, comprising:
performing 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.
