1. A method for decoding a video signal, the method comprising:
selecting candidate units among reconstructed neighboring units adjacent to a decoding target unit;
generating a candidate unit set for the decoding target unit based on the selected candidate units;
deriving motion information of the decoding target unit based on the generated candidate unit set; and
deriving a prediction block of the decoding target unit based on the derived motion information,
wherein the step of selecting candidate units selects units, which have a reference picture list different from a reference picture list of the decoding target unit and use the same reference picture as the decoding target unit, among the reconstructed neighboring units,
wherein the reconstructed neighboring units include an upper neighboring unit adjacent to an upper portion of the decoding target unit, a left neighboring unit adjacent to the left of the decoding target unit, a right upper corner unit positioned at a right upper corner of the decoding target unit, a left upper corner unit positioned at a left upper corner of the decoding target unit, and a left lower corner unit positioned at a left lower corner of the decoding target unit.
