Abstract: Provided is an inter-layer video decoding method. The inter-layer video decoding method includes: determining whether a current block is split into two or more regions by using a depth block corresponding to the current block; generating a merge candidate list including at least one merge candidate for the current block, based on a result of the determination; determining motion information of the current block by using motion information of one of the at least one merge candidate included in the merge candidate list; and decoding the current block by using the determined motion information, wherein the generating of the merge candidate list includes determining whether a view synthesis prediction candidate is available as the merge candidate according to the result of the determination.

Abstract: Provided is a merge mode for determining, by using motion information of another block, motion information of pictures that construct a multiview video. A multiview video decoding method includes obtaining motion inheritance information specifying whether or not motion information of a corresponding block of a first layer which corresponds to a current block of a second layer is available as motion information of the second layer, obtaining a merge candidate list by selectively including the motion information of the corresponding block in merge candidates when the current block that was encoded according to the merge mode is decoded, determining a merge candidate included in the merge candidate list according to merge candidate index information, and obtaining motion information of the current block, based on the merge candidate.

Abstract: A method of generating a parameter set includes obtaining common information inserted into at least two lower parameter sets which belong to the same upper parameter set; determining whether the common information is to be added to at least one among the upper parameter set and the at least two lower parameter sets; and adding the common information to at least one among the upper parameter set and the at least two lower parameter sets, based on a result of the determining.

Abstract: An interlayer video decoding method and apparatus and an interlayer video encoding method and apparatus are provided. The decoding method includes: reconstructing, based on encoding information obtained from a bitstream, a first layer image and a first layer depth map; determining whether a disparity vector is predictable using peripheral blocks of a second layer current block; and when the disparity vector is not predictable using the peripheral blocks, determining a disparity vector of the second layer current block using a default disparity vector and the reconstructed first layer depth map.
