Abstract

An RF modulator includes a C/L delay compensation function of compensating for a delay of a luminance signal with respect to a chrominance signal occurring during demodulating a video signal in a TV set. The RF modulator includes a C/L delay compensation unit delaying a luminance signal by 170 nsec and combining the delayed luminance signal with a chrominance signal to output a composite image signal having a C/l delay of −170 nsec and a frequency modulation unit modulating the video signal received from the C/L delay compensation unit into a high frequency signal of a predetermined broadcasting channel in a single module or package. The RF modulator outputs a video signal having the luminance signal delayed by 170 nsec with respect to the chrominance signal and complies with a C/L delay standard without adding any additional C/L delay compensation unit to the RF modulator.
