Abstract: A video encoding method includes: generating encoding symbols by performing source coding on subregions formed by splitting a picture in a vertical direction, based on blocks having a predetermined size; determining a reference block to be referred to for determining code probability information of a start block in a current subregion, the reference block being determined from among boundary blocks of a neighboring subregion which are encoded before the start block and adjacent to a boundary between the current subregion and the neighboring subregion; performing entropy encoding on blocks of the current subregion, starting from the start block, by using the encoding symbols of the blocks of the current subregion based on the code probability information of the start block determined by using code probability information of the determined reference block; and performing entropy encoding on another subregion in parallel with performing entropy encoding on the current subregion.

Abstract: An inter-view video decoding method may include determining a disparity vector of a current second-view depth block by using a specific sample value selected within a sample value range determined based on a preset bit-depth, detecting a first-view depth block corresponding to the current second-view depth block by using the disparity vector, and reconstructing the current second-view depth block by generating a prediction block of the current second-view depth block based on coding information of the first-view depth block.

Abstract: An inter-layer video decoding method is described including reconstructing a color image and a depth image of a first layer based on encoding information about the color image and the depth image of the first layer obtained from a bitstream. When it is determined that a prediction mode of a current block of a second layer image to be decoded is a view synthesized prediction mode based on an image synthesized from the first layer image a determination is made whether to perform luminance compensation on the second layer current block to be reconstructed. Use of the view synthesized prediction mode to reconstruct the second layer current block depends on the luminance compensation determination.
