1. A method implemented by a decoder, the method comprising:
receiving a sub-bitstream including: a sub-picture of a picture partitioned into a plurality of slices including a first slice, a parameter set associated with the picture and the sub-picture, and a slice header associated with the first slice;
parsing the parameter set to obtain an identifier and a length of a slice address of the first slice;
determining the slice address for the first slice from the slice header based on the identifier and the length of the slice address;
employing the length from the parameter set to determine bit boundaries for interpreting the slice address from the slice header;
obtaining a slice index based on the identifier and the slice address; and
decoding the sub-bitstream to create a video sequence of sub-pictures including the first slice.
