Abstract
A method of decoding video data from a bitstream, the bitstream comprising video data corresponding to one or more slices. The bitstream comprises a picture header comprising syntax elements to be used when decoding one or more slices, and a slice header comprising syntax elements to be used when decoding a slice. The decoding comprises in a case where information which can be signalled in the picture header or in the slice header is signalled in the picture header, a picture header is to be signalled in a slice header, permitting parsing of information which may otherwise be signalled in a slice header and a picture header, in only one of the slice header or picture header; imposing that the picture header is not in the slice header, and decoding said bitstream using said syntax elements.
