Title:
METHOD AND APPARATUS FOR VIDEO ENCODING/DECODING USING IBC MODE, AND METHOD FOR TRANSMITTING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2020/184991
Kind Code:
A1
Abstract:
The present disclosure discloses a video decoding method. A video decoding method according to one embodiment comprises the steps of: determining a prediction mode of a current block on the basis of prediction mode information of the current block obtained from a bitstream; obtaining a transform coefficient block of the current block from the bitstream; inversely quantizing the transform coefficient so as to generate an inversely quantized transform coefficient block; determining a transform kernel for the quantized transform coefficient block; and performing an inverse transformation on the quantized transform coefficient block using the transform kernel so as to generate a residual block of the current block.
