Method and apparatus for incoding and decoding regarding position of integer pixel

In the video decoding method, from the discharge parity obtaining a vector (disparity vector), the position of the current pixel in the current layer having a composition of the sub-pixel unit for inter-layer prediction between the images belonging to the current layer and the reference layer, acquiring a display parity vector by using the prediction information of the candidate area of ​​an integer pixel in a reference layer corresponding to the pointing position reference corresponding to the phase and position of the integer pixel is determined to determine the location of the (integer pixel) layer of the current layer the video decoding method includes performing a decoding of the picture is started.
