Claim 6:
7. A method implemented by an encoder, the method comprising:
determining luma mapping with chroma scaling (LMCS) parameters for a slice;
encoding the slice into a bitstream as a coded slice;
encoding the LMCS parameters into a LMCS adaptation parameter set (APS) of the bitstream; and
encoding into the bitstream data related to the coded slice that references the LMCS APS,
wherein the bitstream further comprises an adaptive loop filter (ALF) APS containing ALF parameters,
wherein each APS includes an APS identifier (ID) selected from a predefined range, wherein the predefined range is determined based on a parameter type of each APS, and
wherein APSs of a particular type share the same value space for the APS IDs and different types of APSs use different value spaces of the APS IDs.
