IMAGE OR VIDEO CODING BASED ON TRANSFORM SKIP- AND PALETTE CODING-RELATED ADVANCED SYNTAX ELEMENT

Title:

IMAGE OR VIDEO CODING BASED ON TRANSFORM SKIP- AND PALETTE CODING-RELATED ADVANCED SYNTAX ELEMENT

Document Type and Number:

WIPO Patent Application WO/2021/066609

Kind Code:

A1

Abstract:

According to the disclosure of the present document, dependency conditions can be defined for efficiently parsing/signaling syntax elements having dependency on transform skip- and/or palette coding-related information, and, on the basis of the dependency conditions, whether or not to parse the transform skip- and/or palette coding-related information can be determined. Accordingly, bits that need to be signaled for video/image coding can be reduced, and coding efficiency can be improved.
