Abstract:
An inter-prediction method according to the present invention comprises the steps of: deriving motion information of a current block; and generating a prediction block for the current block on the basis of the derived motion information. According to the present invention, computational complexity can be reduced and encoding efficiency can be improved.

Claim (Index 1):
A method for decoding a video signal, the method comprising:\n generating a merge candidate list of the current block by using neighboring blocks adjacent to the current block, each of the neighboring blocks having motion information; deriving, based on a merge index, motion information of a current block from the merge candidate list, the merge index specifying a merge candidate included in the merge candidate list; generating a prediction block for the current block based on the derived motion information; obtaining a residual block for the current block by decoding the input bitstream; generating a reconstruction block for the current block by adding the residual block to the prediction block; and applying in-loop filter on the reconstruction block, wherein the in-loop filter is at least one of a deblocking filter and an SAO (Sample Adaptive Offset) filter, wherein the derived motion information includes prediction direction information and both of L0 motion information and L1 motion information, wherein, when the prediction direction information of the current block indicates a bi-prediction and a size of the current block is smaller than a pre-determined size, the prediction direction information indicating the bi-prediction is changed to indicate a uni-prediction and the prediction block of the current block is generated by performing motion compensation based on only the L0 motion information among the L0 motion information and the L1 motion information, wherein, when the prediction direction information indicates the bi-prediction and the size of the current block is equal to or greater than the pre-determined size, the prediction direction information indicating the bi-prediction is not changed to indicate the uni-prediction and the prediction block of the current block is generated by performing the motion compensation based on both the L0 motion information and the L1 motion information, and wherein the pre-determined size is representative of one of 8\u00d78, 16\u00d716, or 32\u00d732.
