Claim 0:
1. A method of decoding a video, the method comprising:
deriving a plurality of merge candidates for a current block from neighboring blocks adjacent to the current block, the neighboring blocks including at least one of a spatial neighboring block or a temporal neighboring block;
constructing a merge candidate list by adding the plurality of merge candidates thereto, wherein during the construction of the merge candidate list, a new merge candidate generated based on two of the plurality of merge candidates is further added to the merge candidate list;
after completing the construction of the merge candidate list, selecting a first merge candidate and a second merge candidate from the merge candidate list; and
obtaining prediction samples of the current block based on first motion information derived from the first merge candidate and second motion information derived from the second merge candidate,
wherein two pieces of index information are explicitly signaled via a bitstream to select the first merge candidate and the second merge candidate, first index information being used to select the first merge candidate and second index information being used to select the second merge candidate,
wherein, in response to the second index information being less than the first index information, a merge candidate that has an index identical to the second index information is selected as the second merge candidate, and
wherein, in response to the second index information being greater than or equal to the first index information, a merge candidate that has an index derived by adding 1 to the second index information is selected as the second merge candidate.
