CHROMA MOTION VECTOR REFINEMENT USING RECONSTRUCTED LUMA OR CHROMA

原文（中国語）

In an inter-frame prediction process for frames of video, a luma block is selected to be coded first for a current coding unit to form a reconstructed luma block of the current coding unit. MV(s) are refined that point from the luma block to a prediction luma block in a reference picture of the video. One of the refined MV(s) is selected to code chroma blocks for the current coding unit.
