The television signal recording/reproducing system digitally records and reproduces television signals composed of a luminance signal, a chrominance signal and a resolution compensation signal included in predetermined television scanning lines. The system includes a Y/C separating circuit for separating the luminance signal Y from the chrominance signal C. The luminance signal.Y and the resolution compensation signal are combined onto a first signal line. A demodulating circuit demodulates the chrominance signal into a color difference signal and outputs the demodulated signal to a second signal line. A digital video signal recorder digitally process the signals on the first signal line separately from the signals on the second signal line and records the digitally processed signals. In this manner, the resolution compensation signal is processed with the luminance signal and the resolution compensation signal can be accurately recorded.
