Abstract
According to an embodiment disclosed in the present specification, a history-based motion vector prediction (HMVP) candidate set with respect to a current block may be derived based on a history, the HMVP candidate set may be updated or initialized according to a condition, and motion information of the current block may be derived based on the HMVP candidate set, through which inter prediction efficiency can be improved.
