Claim 10:
11. A video decoder, comprising:
a memory having stored instructions;
a processor for executing the instructions to:
in case that there are a first prediction and a second prediction corresponding to a coding block, determine a partition type of the coding block, derive first motion information regarding the first prediction in the coding block and second motion information regarding the second prediction in the coding block, and acquire a prediction sample in the coding block on the basis of the first motion information and the second motion information,
wherein
the first motion information regarding the first prediction is derived from a first merge candidate specified by first index information among a plurality of merge candidates included in a merge candidate list, and the second motion information regarding the second prediction is derived from a second merge candidate specified by second index information among the plurality of merge candidates included in the merge candidate list;
wherein when a value of the second index information is smaller than a value of the first index information, the second merge candidate has an index equal to the value of the second index information.
