In the method, syntax information of a coding unit (CU) is decoded from a coded video bitstream. The syntax information is signaled in a picture header (PH) and includes chroma quantization parameter (QP) offsets in a PH level. The chroma QP offsets include at least one of a Cb offset, a Cr offset, and a CbCr offset. Further, quantization parameters for the CU are determined based on the chroma QP offsets in the PH level and a quantization parameter range offset of the CU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for signaling of chroma quantization parameters","description":"According to an aspect of the disclosure, a method of video decoding performed in a video decoder is provided.
