Claim 0:
1. A method for decoding a video signal with a decoding apparatus, comprising:
generating, with the decoding apparatus, a first prediction sample of a current block;
determining, with the decoding apparatus, a weight prediction parameter set of the current block by using a predetermined reference region, the reference region being a region reconstructed before the current block and including a neighboring region spatially adjacent to the current block; and
generating, with the decoding apparatus, a second prediction sample of the current block by applying the weight prediction parameter set to the first prediction sample,
wherein the neighboring region is determined based on information signaled from a bitstream,
wherein the information specifies a position of the neighboring region and is used to determine the weight prediction parameter set, and
wherein the neighboring region includes a bottom-left neighboring region or a right-top neighboring region.
