Title:
METHOD AND DEVICE FOR PROCESSING VIDEO SIGNAL FOR INTER-PREDICTION
Document Type and Number:
WIPO Patent Application WO/2020/180129
Kind Code:
A1
Abstract:
Embodiments in the present specification provide an encoding and decoding method of a video signal for inter-prediction. A decoding method according to an embodiment of the present specification includes: a step for acquiring, from first coding information about a first level unit, a first flag related to whether second motion vector difference (MVD) information is encoded among first MVD information for predicting a first direction and the second MVD information for predicting a second direction; a step for acquiring, from second coding information about a second level unit lower than the first level unit, a second flag related to whether a symmetric MVD (SMVD) is applied to the current block on the basis of the first flag; a step for determining the first MVD with respect to the current block on the basis of the first MVD information; a step for determining the second MVD on the basis of the second flag; a step for determining a first motion vector and a second motion vector on the basis of the first MVD and the second MVD; and a step for generating a prediction sample of the current block on the basis of the first motion vector and the second motion vector.
