Abstract
According to the present invention, a method for decoding a video in a skip mode comprises the steps of: deriving a pixel value of an estimation block for a current block; deriving an error compensation value for the current block; and deriving a pixel value of a final prediction block using the pixel value of the prediction block and the error compensation value. According to the present invention, the amount of transmitted information is minimized, and the efficiency of video encoding / decoding is improved.
