Abstract
An inter prediction method performed by a decoding apparatus according to the present invention comprises the steps of: receiving information associated with an MVD through a bit stream; deriving a candidate motion information list on the basis of a neighboring block of a current block; deriving an MVP of the current block on the basis of the candidate motion information list; deriving a motion vector of the current block on the basis of the MVP and the MVD; and generating a prediction sample with respect to the current block on the basis of the motion vector. According to the present invention, a motion vector may be derived on the basis of a candidate motion information list derived on the basis of a neighboring block. Therefore, the amount of data of prediction mode information can be reduced and inter prediction accuracy and overall coding efficiency can be improved.
