Abstract: An interlayer video decoding method includes reconstructing color and depth images of a first layer obtained from a bitstream, based on encoding information of the color and depth images of the first layer; determining whether a prediction mode of a current block of a second layer image to be decoded corresponds to a merge mode; adding at least one of an inter-view candidate, a spatial candidate, a disparity candidate, a view synthesis prediction candidate, and a temporal candidate to candidates to a merge candidate list according to a predetermined priority in response to the prediction mode corresponding to the merge mode; selecting at least one candidate from the merge candidate list, based on a merge index obtained from the bitstream, to decode the current block based on the selected at least one candidate. The view synthesis prediction candidate is added to the merge candidate list with a fixed priority.
