Claim 7:
8. 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 video comprising a current video block and a bitstream of the video,
wherein a range of a value of a first syntax element specifying a number of points in a quantization parameter (QP) table associated with the conversion of the current video block is dependent on one or more other syntax elements comprising a second syntax element according to a rule,
wherein the rule specifies that the range of the value of the first syntax element is based on a value of the second syntax element specifying a starting luma and chroma QP used to describe the QP table, and
wherein a maximum allowed value of the first syntax element is equal to (K−the value of the second syntax element), K being a positive integer.
