Claim 16:
17. A non-transitory computer-readable storage medium storing instructions that cause a processor to:
perform a conversion between a video comprising one or more pictures and a bitstream of the video,
wherein the bitstream conforms to a format rule,
wherein the format rule specifies a constraint on a value of a first syntax element that specifies whether a second syntax element is present in a picture header syntax structure of a current picture, and
wherein the second syntax element specifies a value of a picture order count (POC) most significant bit (MSB) cycle of the current picture, and
wherein the value of the first syntax element is equal to zero in response to a value of a flag equaling to zero and an inter-layer reference picture (ILRP) entry being in a reference picture list of a slice of the current picture, and wherein the flag specifies whether an indexed layer uses inter-layer prediction.
