Title:
ENCODING/DECODING VIDEO PICTURE DATA
Document Type and Number:
WIPO Patent Application WO/2023/246274
Kind Code:
A1
Abstract:
The present application relates encoding/decoding a video picture into a bitstream of encoded video picture data comprising temporal predicting a video picture block by obtaining a temporal predicted block based on at least one reference block of at least one reference picture pointed to by at least one motion vector associated with the video picture block, wherein if the temporal prediction of the video picture block is based on a single reference block of a reference, then the method further comprises: - padding (402) a padding region (SZ) of the reference block based on a motion vector derived from a nearest subblock of the video picture block inside the video picture; and - determining a size (M) of the padding region (SZ) based on said motion vector.
