Kind Code:
A1
Abstract:
Disclosed is a decoding method for motion information, according to one embodiment, comprising the steps of: determining a first group of motion vector candidates by using at least one motion vector among spatial peripheral blocks and temporal peripheral blocks related to a current block; determining a second group of basic motion vector candidates according to a template matching or bidirectional matching result based on each motion vector candidate included in the first group; selecting, from the second group, a basic motion vector corresponding to the current block; and determining a motion vector of the current block by changing the basic motion vector according to a shift distance and a shift direction.
