1. A method decoding video data in a coded video data bitstream with a decoding apparatus, the method comprising:
obtaining, with the decoding apparatus, skip mode indication information, the skip mode indication information specifying whether a skip mode is applied,
deriving, with the decoding apparatus, a motion vector predictor of a current block when the skip mode indication information specifies that skip mode is not applied;
predicting, with the decoding apparatus, a pixel value of the current block based on the motion vector predictor of the current block to generate prediction samples of the current block; and
reconstructing the current block based on the prediction samples,
wherein deriving the motion vector predictor of the current block includes:
constructing, with the decoding apparatus, a motion vector predictor list of the current block, the motion vector predictor list including at least two motion vector candidates, list index information being assigned to each of the motion vector candidates included in the motion vector predictor list, the list index information specifying each motion vector candidate, the motion vector candidates including motion vectors of neighboring blocks adjacent to the current block,
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 used for the current block, and
extracting, with the decoding apparatus, from the motion vector predictor list, the motion vector candidate having the list index information corresponding to the obtained motion vector index information, the extracted motion vector candidate being used as the motion vector predictor of the current block.
