Title:
IMAGE OR VIDEO CODING BASED ON PALETTE ESCAPE CODING
Document Type and Number:
WIPO Patent Application WO/2021/040398
Kind Code:
A1
Abstract:
According to the disclosure of the present document, information used in a palette coding mode may be effectively signaled. For example, information relating to availability of a palette mode may be signaled, and information relating to a quantized escape value may be signaled on the basis of the information relating to the availability of the palette mode. In addition, as a quantization parameter for the quantized escape value, minimum quantization parameter information relating to a transform skip mode may be signaled. Accordingly, information required for palette mode coding can be efficiently signaled, and escape coding efficiency in a palette mode can be improved.
