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.

Abstract: Provided are a method and apparatus for inter-layer encoding and a method and apparatus for inter-layer decoding video using residual prediction. The inter-layer video decoding method includes: obtaining a decoded first layer image from a first layer bitstream; determining, based on residual prediction information obtained from a second layer bitstream, whether to perform residual prediction performed on a second layer block by referring to a first layer block corresponding to the second layer block within the first layer image; in response to determining not to perform the residual prediction, obtaining luminance compensation information from the second layer bitstream and determining whether to perform luminance compensation based on the luminance compensation information; and in response to determining to perform the luminance compensation, performing the luminance compensation on the second layer block.

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.
