1. A method for decoding a video signal with an image decoding apparatus, comprising:
determining a collocated picture of a current block based on collocated picture information signaled from an encoding apparatus,
wherein the collocated picture information is index information specifying the collocated picture of the current block among reference pictures in a reference picture list, and wherein the collocated picture is determined as one of the reference pictures included in the reference picture list specified by the collocated picture information;
deriving a temporal motion vector based on a motion vector of a collocated block corresponding to the current block in the collocated picture;
generating a motion vector candidate list for the current block by using the temporal motion vector;
deriving a motion vector of the current block based on the motion vector candidate list; and
performing motion compensation on the current block based on the derived motion vector.
