Abstract: Provided is a method of reconstructing multilayer images including obtaining RAP picture information of a plurality of layers including a base layer and an enhancement layer, independently decoding a RAP picture of the base layer by using RAP picture information, and independently decoding a RAP picture of the enhancement layer by using RAP picture information.

Abstract: Provided are an inter-layer video encoding method and apparatus therefor and an inter-layer video decoding method and apparatus therefor. An inter-layer video decoding method involves reconstructing a first layer image, based on encoding information obtained from a first layer bitstream; in order to reconstruct a second layer block determined as a predetermined partition type and to be in a prediction mode, determining whether to perform illumination compensation for the reconstructed second layer block determined by using a first layer reference block that is from among the reconstructed first layer image and corresponds to the second layer block; and generating the reconstructed second layer block by using inter-layer prediction information obtained from a second layer bitstream and the first layer reference block, and generating a second layer image including the reconstructed second layer block whose illumination is determined according to whether the illumination compensation was performed.

Abstract: Provided is a video decoding method including determining whether a random access point (RAP) picture is positioned in an enhancement layer; determining whether a random access skipped leading (RASL) picture related to the RAP picture is output; and if the RAP picture is positioned in the enhancement layer and the RASL picture is determined not to be output, activating a SPS corresponding to the RAP picture when the RAP picture that is not at a start point of a CVS is decoded.
