Title:
IMAGE DECODING METHOD AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/201550
Kind Code:
A1
Abstract:
A method by which a decoding device decodes an image, according to the present document, comprises the steps of: acquiring a dependent quantization available flag about whether dependent quantization is available; acquiring a sign data hiding available flag about whether sign data hiding is available; and acquiring, on the basis of the dependent quantization available flag and the sign data hiding available flag, a transform skip residual coding (TSRC) available flag about whether TSRC is available.
