Abstract
Provided are a method and apparatus for correcting quantized coefficients. In the method, statistical values of coefficients and quantized coefficients are extracted from a received video data stream, coefficient correction values for each pixel position in blocks are determined by using the statistical distribution of the coefficients depending on the statistical values, and then the coefficients are corrected by respectively adding the coefficient correction values to corresponding coefficients of respective pixel positions.
