Abstract

A motion vector refinement apparatus includes a first storage device, a motion vector predictor (MVP) derivation circuit, and a decoder side motion vector refinement (DMVR) circuit. The MVP derivation circuit derives a first MVP for a current block, stores the first MVP into the first storage device, and performs a new task. The DMVR circuit performs a DMVR operation to derive a first motion vector difference (MVD) for the first MVP. The MVP derivation circuit starts performing the new task before the DMVR circuit finishes deriving the first MVD for the first MVP.
