Title:
METHOD FOR IMAGE DECODING FOR IMAGE INFORMATION CODING, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/158049
Kind Code:
A1
Abstract:
The method for image decoding carried out by a decoding device, according to the present document, comprises the steps of: acquiring a transform skip residual coding (TSRC) availability flag relating to whether TSRC is available or not; acquiring residual information of residual coding syntax for a current block derived on the basis of the TSRC availability flag; deriving a residual sample of the current block on the basis of the residual information; and generating a reconstructed picture on the basis of the residual sample, wherein the TSRC availability flag is acquired on the basis of a dependent quantization availability flag relating to whether dependent quantization is available or not.
