1. A method of video encoding by an encoding apparatus, the method comprising:
determining whether a first pixel belongs to a Largest Coding Unit (LCU) to which a co-located block belongs, wherein the first pixel neighbors the co-located block and is located at a lower right side of the co-located block, wherein the co-located block corresponds to a current block and is located in a reference picture;
determining a reference prediction unit (colPu) which is a prediction block encompassing a modified location (x, y) in the reference picture;
deriving a temporal motion vector predictor candidate for the current block from motion information of the determined reference prediction unit;
deriving a motion vector of the current block based on the temporal motion vector predictor candidate;
deriving a predicted pixel of the current block based on the motion vector of the current block; and
generating a bitstream including information on prediction for the current block,
wherein based on the first pixel not belonging to the LCU, the modified location is specified by a position ((xPCtr>>4)<<4, (yPCtr>>4)<<4), and wherein a position (xPCtr, yPCtr) is a position of a second pixel located at the bottom right side among four central pixels of the co-located block.
