Title:
QUANTIZATION MATRIX ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2020/251332
Kind Code:
A1
Abstract:
The present disclosure provides a video decoding method comprising the steps of: determining one or more adaptive parameter sets including a quantization matrix set consisting of a plurality of quantization matrices; determining an adaptive parameter set including a quantization matrix set applied to a current picture or a current slice from among the one or more adaptive parameter sets; dequantizing transform coefficients of a current block of the current picture or the current slice on the basis of the quantization matrix set of the determined adaptive parameter set; and reconstructing the current block on the basis of the dequantized transform coefficients, wherein the adaptive parameter set includes encoding information applied to one or more pictures or slices.
