Abstract
PURPOSE: To make narrow-band recording possible by performing the recording giving both I and Q components at the same time.
CONSTITUTION: A color video signal is separated into a luminance signal and chrominance signal by low-pass filter 2 and band-pass filter 6; the luminance signal is supplied to adder 5 by way of FM modulator 3 and high-pass filter 4 and the chrominance signal is passed through subcarrier generator 8, ±45° phase shifter 9 and demodulator 7 and then added to the luminance signal by adder 5 before being supplied to recording regeneration system 10. The luminance signal of the regenerated signal is filtered by high-pass filter 11, demodulated by demodulator 12 and then supplied to adder 13, and the color signal is filtered by low-pass filter 14 and supplied to subtracter 16, 1H delay line 15 and adder 21. An I signal from adder 21 and a Q signal with its polarity inverted at every 1H from subtracter 16 are modulated by balanced modulators 19 and 20 and the luminance signal is added by adder 13 to the chrominance signal, with both the I and Q signal after orthogonal two-phase modulation, appearing at the output terminal of adder 20.
