Abstract
Device and method for correcting a color distortion on a TV receiver, is disclosed, the method including a multi-path channel estimation step wherein a transmission channel existing between a transmitted side in a broadcasting station and a color demodulating circuit in a TV receiver is estimated for obtaining an impulse response using a reference signal transmitted from the broadcasting station for equalizing a multi-path channel, a color subcarrier phase error calculation step wherein a phase error of a color subcarrier between the transmitter side of the broadcasting station and the TV receiver is calculated using the estimated impulse response, and a phase correction of a reproduced color subcarrier step wherein a phase error on the TV receiver in reproduction of a color is corrected as much as the phase error obtained in the color subcarrier phase error calculation step.
