1. A processor implemented method of decoding a video comprising views, the method comprising: constructing a basic merge motion candidate list for an independent view using motion information on a spatial neighboring block to a current block and motion information on a collocated block in a temporal reference picture; determining whether a picture to which the current block belongs is a depth map information picture or a dependent view picture; in response to the determining, constructing an extended merge motion candidate list based on the basic merge motion candidate list using information on a view identifier of the dependent view or information on the depth map; and decoding, based on the determination, the video comprising the views using the extended merge motion candidate list or the basic merge motion candidate list, wherein the extended merge motion candidate list comprises any one or any combination of two or more of information on a block of a different view corresponding to the current block, view synthesis prediction information, and inter-view disparity information.
