Summary:Interlayer video decoding comprising reconstructing (21) a first layer image and a first layer depth map based on encoding information obtained from a bitstream; determining (23) whether a disparity vector is predictable using peripheral blocks of a second layer current block, the peripheral blocks comprising prediction units temporally or spatially neighboring the second layer current block; and when the disparity vector is not predictable using the peripheral blocks, determining (25) a disparity vector of the second layer current block using a default disparity vector and the first layer depth map. The determined disparity vector comprises a horizontal component value which is derived by using the default disparity vector and the first layer depth map, and a vertical component value set to 0.
