Title:
RESIDUAL SIGNAL REARRANGEMENT METHOD AND IMAGE DECODING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/009460
Kind Code:
A1
Abstract:
A residual signal rearrangement method and an image decoding apparatus are disclosed. According to one embodiment of the present invention, a residual signal rearrangement method comprises the steps of: decoding, from a bitstream, transform coefficients in a transform block of a current block and transform type information indicating a transform type applied to the transform block; deriving a residual block from the transform coefficients according to the transform type indicated by the transform type information; and rearranging residual signals in the residual block according to any one of one or more rearrangement types.
