Claim One:
1. A video decoding apparatus for decoding a multi-view video, the apparatus comprising: an entropy decoding unit configured to derive video information required for decoding a current block by entropy-decoding a bitstream; a memory configured to store pictures referred to decode the current block; a prediction unit configured to derive a first disparity vector based on a disparity vector of a neighboring block of the current block in the same view by using the video information, to derive a second disparity vector by using the first disparity vector and a reference view depth, to derive disparity vectors of neighboring blocks of the current block other than the neighboring block of the current block, to select a disparity vector having a size of the smallest difference from a size of the second disparity vector among the disparity vectors as a third disparity vector, and to generate a prediction sample of the current block by using one of the first disparity vector, the second disparity vector, and the third disparity vector; and a filter unit configured to apply filtering to a current picture which has been reconstructed using the prediction sample of the current block, wherein the second disparity vector is generated based on a maximum depth value among corner depth values of a corresponding block in the reference view, and wherein the corresponding block is a block indicated by the first disparity vector at corresponding position of the current block in the reference view.
