Abstract
A video decoding technique includes parsing a bitstream to determine a quantization parameter (QP) for a luma component of a region from a data unit of a parameter set included in the bitstream, determining a flag from the data unit of the parameter set, determining, in a case that the flag is equal to a first value, a QP for a chroma component of the region as a first function of the QP for the luma component and a default chroma delta QP indicated by the flag, determining, in a case that the flag is equal to a second value, the QP for the chroma component of the region by (a) obtaining a delta chroma QP from the data unit, and (b) determining the QP for the chroma component as a second function of the QP for the luma component and the delta chroma QP.
