Claim One:
1. A method of processing a video signal, the method comprising: obtaining index information from the video signal, the index information specifying a motion vector candidate to be used as a motion vector predictor of a current block; deriving at least one spatial motion vector candidate from at least one neighboring block of the current block; constructing a motion vector candidate group of the current block, the motion vector candidate group comprising a plurality of motion vector candidates including the derived at least one spatial motion vector candidate; assigning a motion vector candidate specified by the index information from among the motion vector candidate group to the motion vector predictor of the current block; and decoding the current block based on the motion vector predictor, wherein the deriving the at least one spatial motion vector candidate includes: assigning a motion vector of the at least one neighboring block to the at least one spatial motion vector candidate when a reference picture list for the at least one neighboring block is different from a reference picture list for the current block and a reference picture of the at least one neighboring block is same as a reference picture of the current block based on picture order count (POC) information.
