Title:
METHOD AND DEVICE FOR VIDEO CODING USING REARRANGEMENT OF PREDICTION SIGNALS IN INTRA BLOCK COPY MODE
Document Type and Number:
WIPO Patent Application WO/2024/034886
Kind Code:
A1
Abstract:
The present embodiment discloses a method and device for video coding using rearrangement of prediction signals in an intra block copy mode. In the present embodiment, a video decoding device obtains a division direction indicating horizontal division or vertical division of a current block, and obtains the ratio of subblocks with respect to the current block. The video decoding device generates an initial prediction block of the current block according to an intra block copy (IBC) mode. The image decoding device divides the initial prediction block into subblocks on the basis of the division direction and the ratio of subblocks, and then rearranges the order of the subblocks to generate a final prediction block of the current block.
