Title:
APPARATUS AND METHOD FOR ENCODING AND DECODING MOTION INFORMATION BY USING NEIGHBORING MOTION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/256468
Kind Code:
A1
Abstract:
Disclosed is a method for decoding motion information, wherein the method comprises the steps of: obtaining, from a bitstream, change information indicating whether motion information of a neighboring block is changed; checking the number of pictures included in a reference picture list of a current block when the change information indicates a change of the motion information and an upper block can use one reference picture list; in consideration of the number of pictures, selecting a reference picture of the neighboring block or a picture different from the reference picture of the neighboring block as a reference picture of the current block; when the reference picture of the neighboring block is selected as the reference picture of the current block, obtaining a motion vector of the current block by applying an offset to at least one of the x component or the y component of a motion vector of the neighboring block; and reconstructing the current block by using a reference block indicated by the motion vector of the current block within the reference picture of the current block.
