Video decoding apparatus and method for decoding multi-view video

Abstract

The present invention relates to a video decoding apparatus and method for decoding a multi-view video, and the method for decoding a video, according to the present invention, is the video decoding method for decoding a multi-view video, comprising the steps of: inducing video information required for decoding a current block by entropy-decoding a bitstream; inducing a first disparity vector based on a neighboring block of the current block in the same view by using the video information, inducing a second disparity vector by using the first disparity vector and a reference view depth, and inducing a third disparity vector using the difference between the first disparity vector and the second disparity vector; inducing a prediction sample of the current block by using one of the first disparity vector, the second disparity vector, or the third disparity vector; and applying filtering to a current picture which has been restored using the prediction sample.
