Abstract: An inverse conversion method for an ultra-high resolution video codec is disclosed. The inverse conversion method for an ultra-high resolution video codec according to the present invention comprises the steps of receiving a first pixel value of multiple pixel values; receiving one pixel value of the pixel values other than the first pixel value as a second pixel value; calculating a first intermediate value through a butterfly calculation by respectively applying the corresponding coefficient values to the inputted first pixel value and the second pixel value; and replacing the first pixel value with the calculated first intermediate value to re-perform the inverse conversion method. [Reference numerals] (50,CC,GG) 16�16 output value;(AA,BB,EE,FF) Input a pixel value;(DD,HH) 32�32 output value
