Title:
METHOD FOR ENCODNG AND DECODING MOTION INFORMATION, AND APPARATUS FOR ENCODNG AND DECODING MOTION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/060158
Kind Code:
A1
Abstract:
A video decoding method is disclosed, the method comprising: determining a prediction mode of a current block as one of a skip mode or a merge mode; when a motion vector and a merge motion vector difference determined from the merge candidate list of the current block are used, applying one context information to perform entropy decoding on a bitstream thereby obtaining merge candidate information indicating one candidate of the merge candidate list; determining a basic motion vector from one candidate determined on the basis of the merge candidate information in the merge candidate list; and determining the motion vector of the current block by using the distance index of the merge motion vector difference and the direction index of the merge motion vector difference of the current block, and thus using the basic motion vector and the merge motion vector difference.
