Abstract: ABSTRACT QUANTIZATION PARAMETER SIGNALING A quantization parameter signalling mechanism for both SDR and HDR content in video coding is described using two approaches. The first approach is to send the 5 user-defined QpC table directly in high level syntax. This leads to more flexible and efficient QP control for future codec development and video content coding. The second approach is to signal luma and chroma QPs independently. This approach eliminates the need for QpC tables and removes the dependency of chroma quantization parameter on luma QP.
