Abstract
An image decoding method performed by a decoding apparatus, includes deriving a history-based motion vector prediction (HMVP) buffer for a current block based on a history, and deriving motion information of the current block based on an HMVP candidate included in the HMVP buffer, thereby increasing inter prediction efficiency.
