Abstract
Examples of block-level signaling of quantization parameter offsets is described. Such block-level signaling of quantization parameter offsets provides block level flexibility to determine a more precise chroma quantization parameter (QP) for a chroma block. With the block-level quantization parameter offset signaling described in this disclosure, there is more flexibility in defining the chroma QP, resulting in more accurate determination of chroma QP on a chroma block-by-chroma block basis.
