    摘要： Provided is an inter-layer decoding method 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, wherein the encoding information is obtained from a bitstream; determining, from the depth image of the first layer, a depth image block of the first layer which corresponds to a current block of a second layer image to be decoded; determining whether an area included in the determined depth image block of the first layer deviates from a boundary of the depth image of the first layer; when the area included in the depth image block deviates from the boundary, determining a depth value of the area deviating from the boundary of the depth image; determining a disparity vector indicating a corresponding block of the first layer image with respect to the current block, based on the determined depth value of the area deviating from the boundary of the depth image; and reconstructing the current block by using the disparity vector.

    摘要： 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.

    摘要： A method of decoding multi-layer video includes decoding a first layer picture, storing the decoded first layer picture in a decoded picture buffer (DPB), and marking the first layer picture as a short-term reference picture; obtaining interlayer reference picture set (RPS) information regarding a second layer picture having a same first picture order count (POC) as the first layer picture; marking the first layer picture, which is marked as the short-term reference picture, as a long-term reference picture, based on the interlayer RPS information; performing interlayer prediction with respect to the second layer picture with reference to the first layer picture; decoding the second layer picture based on a result of performing the interlayer prediction; and, after the second layer picture is decoded, marking the first layer picture, which is marked as the long-term reference picture, as a short-term reference picture.
