摘要： A method for decoding a video including a plurality of views, according to one embodiment of the present invention, comprises the steps of: configuring a base merge motion candidate list by using motion information of neighboring blocks and a time correspondence block of a current block; configuring an extended merge motion information list by using motion information of a depth information map and a video view different from the current block; and determining whether neighboring block motion information contained in the base merge motion candidate list is derived through view synthesis prediction.

摘要： Disclosed are a video encoding/decoding method and apparatus including a plurality of views. The video decoding method including the plurality of views comprises the steps of: inducing basic combination motion candidates for a current Prediction Unit (PU) to configure a combination motion candidate list; inducing expanded combination motion candidates for the current PU when the current PU corresponds to a depth information map or a dependent view; and adding the expanded combination motion candidates to the combination motion candidate list.
