1. An encoder comprising:
memory; and
circuitry coupled to the memory and configured to:
generate a coded video sequence (CVS); and
generate a sequence parameter set (SPS) including a video parameter set (VPS) identifier, the VPS identifier indicating an identifier of a VPS referred to by the SPS, wherein
when the CVS has more than one layer, the VPS identifier is set to a value greater than zero,
the SPS having the VPS identifier of zero indicates that (i) the SPS does not refer to the VPS and (ii) the CVS includes only one layer, and
any VPS does not have the identifier of the VPS with a value of zero.
