Title:
VIDEO DECODING METHOD AND APPARATUS FOR OBTAINING MOTION VECTOR, AND VIDEO ENCODING METHOD AND APPARATUS FOR OBTAINING MOTION VECTOR
Document Type and Number:
WIPO Patent Application WO/2021/206479
Kind Code:
A1
Abstract:
Provided is a video decoding method comprising: obtaining first coordinates of a collocated block indicating a point spaced apart by a predetermined distance from an upper-left point of the current block; determining that second coordinates corresponding to an upper-left point of an MxN-sized block including the first coordinates of the collocated block become coordinates of the collocated block; obtaining a motion vector of the current block by using a motion vector of the collocated block corresponding to the coordinates of the collocated block; and generating a reconstructed block of the current block by using a prediction block thereof determined by using the motion vector of same.
