1. A method of motion vector prediction corresponding to a video bitstream, the method comprising:
determining, based on coordinates of a current block, a location corresponding to a co-located block of the current block, wherein the determining of the location corresponding to the co-located block includes performing an arithmetic right shift operation;
deriving, based on the determined location of the co-located block, a co-located block motion vector candidate corresponding to the co-located block; and
selecting a motion vector from a plurality of motion vector candidates including the co-located block motion vector candidate.
