performing a conversion between a video comprising one or more pictures and a bitstream of the video according to a format rule,
wherein the format rule specifies to include, in a general constraint syntax structure, a first syntax element indicating whether each picture includes only one slice and whether a picture header syntax structure is present in a slice header, and
wherein the format rule specifies that a presence of a third syntax element in a picture parameter set that specifies whether certain coding information is present in the picture header syntax structure or in the slice header is dependent on a value of a fourth syntax element in the picture g characteristics of pictures referring to the picture parameter set.
