Method and an apparatus for decoding a video signal

A method of decoding video data in a coded video data bitstream with a decoding apparatus, the method comprising:

• constructing, with the decoding apparatus, a motion vector predictor list of a current block, the motion vector predictor list including at least two motion vector candidates, the motion vector candidates including motion vectors of neighboring blocks adjacent to the current block, list index information being assigned to each of the motion vector candidates;
• obtaining, with the decoding apparatus, motion vector index information of the current block from block-level data in the coded video data bitstream, the motion vector index information specifying a motion vector candidate to be used for the current block of the motion vector candidates;
• deriving, with the decoding apparatus, a motion vector predictor of the current block from the motion vector candidate having the list index information corresponding to the obtained motion vector index information;
• obtaining, with the decoding apparatus, a motion vector difference of the current block;
• deriving, with the decoding apparatus, a motion vector of the current block by using the derived motion vector predictor and the motion vector difference;
• and
• predicting, with the decoding apparatus, a pixel value of the current block based on the derived motion vector.
