Claim Text:
1. A method of decoding a video signal with a decoding apparatus, comprising: determining whether a spatial merge candidate is previously decoded or not; determining whether the spatial merge candidate is included in a same MER (Motion Estimation Region) as a current prediction block; when the spatial merge candidate is previously decoded and is not included in the same MER as the current prediction block, determining that the spatial merge candidate is an available merge candidate for inter prediction of the current prediction block; generating a merge candidate list of the current prediction block, the merge candidate list including the available merge candidate; and obtaining prediction samples of the current prediction block based on the merge candidate list, wherein the spatial merge candidate includes at least one of neighboring blocks adjacent to the current prediction block, the neighboring blocks including a left neighboring block, a top neighboring block, a top-right neighboring block, a left-bottom neighboring block and a top-left neighboring block, wherein, when a size of the MER is 8×8 and a size of a coding block is 8×8, the spatial merge candidate is replaced to a replacement block located outside the MER, the coding block including the current prediction block whose a size is 8×4 or 4×8, and wherein, when the size of the MER is not 8×8 and the size of the coding block is not 8×8, the spatial merge candidate is not replaced to the replacement block located outside the MER.
