This abstract first appeared for US patent application 19018589 titled 'IMAGE OR VIDEO CODING BASED ON CHROMA QUANTIZATION PARAMETER OFFSET INFORMATION
Original Abstract Submitted
According to the disclosure of the present document, chroma quantization parameter offset-related information can be signaled through palette syntax coding, and index information for a chroma quantization parameter offset list can be efficiently parsed/signaled on the basis of information about the number of entries in the chroma quantization parameter offset list. Accordingly, bits that are required to be signaled in order to code a video/image can be reduced, and the coding efficiency can be enhanced.
