ABSTRACT:
A digital video signal processing system which includes a scaler converting a video signal having a luminance signal and chrominance signals into a digital RGB signal, further including a hue adjusting part adjusting hue represented by the chrominance signals; wherein the scaler includes an operating part operating a rotational transfer matrix rotation-transforming color coordinates of the chrominance signals according to an adjusting value inputted through the hue adjusting part. Accordingly, a digital video signal processing system and method, in which rotational transform of color coordinates is accomplished by a rotational transfer matrix prior to a color transfer matrix of a scaler without a hardware component therefor is provided.
