Abstract: The present invention relates to a method and apparatus for setting a reference picture index of a temporal merging candidate. An inter-picture prediction method using a temporal merging candidate can include the steps of determining a reference picture index for a current block; and inducing a temporal merging candidate block of the current block and calculating a temporal merging candidate from the temporal merging candidate block, wherein the reference picture index of the temporal merging candidate can be calculated regardless of whether a block other than the current block is decoded. Accordingly, a video processing speed can be increased and video processing complexity can be reduced.

Abstract: Disclosed herein is an image encoding/decoding method. The method of decoding the image includes structuring a motion information candidate list of a current block, selecting a first motion information candidate used for prediction of a first subblock in the current block from the motion information candidate list, selecting a second motion information candidate used for prediction of a second subblock in the current block from the motion information candidate list, generating a prediction sample of the first subblock by performing inter prediction with respect to the first subblock based on the first motion information candidate, and generating a prediction sample of the second subblock by performing inter prediction with the second subblock based on the second motion information candidate. The first and second motion information candidates are any one of candidates in first and second prediction directions in the motion information candidate list, respectively.
