Claim 15:
16. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
determine, for a conversion between a block of a video and a bitstream representation of the video, only one of first information related to a first coding mode and second information related to a second coding mode being included in the bitstream, and
perform the conversion based on the determining,
wherein in the first coding mode, prediction samples are derived based on performing a matrix vector multiplication operation,
wherein in the second coding mode, differences between quantized residuals derived with an intra prediction of the block and predictors of the quantized residuals are included in the bitstream,
wherein in the second coding mode, a transform operation is skipped, and
wherein coding the first information is based on abs(Log2(cbWidth)−Log2(cbHeight), wherein cbWidth denotes a width of the block, cbHeight denotes a height of the block, and abs is an algorithmic symbol for absolute value.
