    摘要: Disclosed herein is an inverse transform method for an ultra-high resolution video codec. In the inverse transform method for an ultra-high resolution video codec using a Forward Discrete Cosine Transform (FDCT) algorithm, one of a plurality of pixel values is input as a first pixel value. One of remaining pixel values other than the first pixel value is input as a second pixel value. A first median value is calculated using a butterfly operation by applying coefficient values, respectively corresponding to the first and second pixel values, to the first and second pixel values. The first pixel value is replaced with the calculated first median value so as to re-perform the inverse transform method.
