Title:
METHOD FOR DECODING VIDEO AND APPARATUS THEREFOR AND METHOD FOR ENCODING VIDEO AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/135448
Kind Code:
A1
Abstract:
Disclosed is a method for decoding video, comprising: determining a scan area containing all of effective transform coefficients in a current block; scanning information on the transform coefficients in the scan area according to a predetermined scan order; performing binary arithmetic decoding on the basis of information on the scanned transform coefficients to generate binary arithmetic decoded information; performing inverse binarization on the binary arithmetic decoded information to obtain the information on the transform coefficients of the current block; performing inverse quantization and inverse transform on the basis of the information on the transform coefficients of the current block to generate a residual block of the current block; and restoring the current block on the basis of the generated residual block. According to the disclosed video decoding method, the binary arithmetic decoding may be performed by using a context model determined on the basis of at least one of the size and the shape of the current block.
