1. A non-transitory computer-readable storage medium which includes a coded bitstream and instructions, the bitstream comprising:
a picture of a video signal or an image signal divided into a plurality of slices, wherein the bitstream identifies a plurality of slice sets, each slice set containing one or more of the plurality of slices; the bitstream further comprises a slice set syntax element for a first slice in a current slice set of the plurality of slice sets, wherein the slice syntax element is quantization parameter information; wherein the slice set syntax element for a second slice is inferred to be equal to the slice set syntax element for the first slice, wherein the second slice is in the current slice set and after the first slice, and wherein the first and second slices are both present in the bitstream as part of the plurality of slices, wherein the instructions, when executed by a processor of a decoding device, cause the decoding device to decode the bitstream into the video signal.
