1. A method of decoding video data from a bitstream, the bitstream comprising encoded video data corresponding to one or more slices in a picture, a picture header, and a slice header, the method comprising:
parsing syntax elements;
decoding the video data from said bitstream using said syntax elements; and
wherein subpicture information is not decoded from the bitstream when a first flag decoded from the slice header indicates that the picture header is present in the slice header,
wherein when (a) a syntax element indicates that a raster scan slice mode is enabled, (b) a number of tiles in the picture is greater than one, and (c) a number of tiles in a slice is equal to the number of tiles in the picture, the picture to be decoded contains only one slice, and
wherein in a case where weighted prediction parameters and adaptation parameter set (APS) ID for adaptive loop filter (ALF) are decoded from the picture header, the adaptation parameter set (APS) ID for adaptive loop filter (ALF) is decoded from the picture header before the weighted prediction parameters are decoded from the picture header.
