Abstract:
According to the present invention, an image encoding apparatus comprises: a motion prediction unit which derives motion information on a current block in the form of the motion information including L0 motion information and L1 motion information; a motion compensation unit which performs a motion compensation for the current block on the basis of at least one of the L0 motion information and L1 motion information so as to generate a prediction block corresponding to the current block; and a restoration block generating unit which generates a restoration block corresponding to the current block based on the prediction block. According to the present invention, image encoding efficiency can be improved.

Claim (Index 1):
A method for decoding a video signal with an image decoding apparatus, comprising:\n obtaining a spatial merge candidate for a current block from a neighboring block adjacent to the current block; determining a collocated block comprised in a collocated picture,\n wherein the collocated picture is a reference picture having the collocated block among reference pictures included in a reference picture list, and \n wherein the collocated block is determined to be either a first block adjacent to a right-bottom position of the current block or a second block comprising a center position of the current block; \n obtaining a temporal merge candidate of the current block based on the collocated block,\n wherein motion information of the temporal merge candidate comprises a motion vector and a reference picture index, and \n wherein the motion vector of the temporal merge candidate is derived from a motion vector of the collocated block within the collocated picture, and \n wherein the reference picture index of the temporal merge candidate is set to a predetermined fixed value regardless of a reference picture index of the neighboring block; \n generating a merge candidate list comprising the spatial merge candidate and the temporal merge candidate; determining a merge candidate for the current block based on the merge candidate list and a merge candidate index, the merge candidate index specifying one of the merge candidates in the merge candidate list; deriving motion information of the current block from motion information of the determined merge candidate; and generating a prediction block corresponding to the current block based on the derived motion information.
