IPC: G11B20/10
Filed: 1986-04-04
Abstract: PURPOSE:To stabilize the operation of a demodulator for a monochromatic video signal as well as a color video signal different in field frequency by modulating a carrier signal having a prescribed frequency by a digital audio signal and recording the modulated signal together with the video signal. CONSTITUTION:The video signal is supplied through a video signal processing circuit 2 and has a vertical synchronizing signal V and a horizontal synchronizing signal H separated by a video signal separating circuit 4 and is supplied to a 4-phase DPSK modulator 18. The modulator 18 generates the carrier wave having integer-fold, for example, 508-fold frequency of the signal H by incorporated VCO, frequency divider, etc., and this carrier wave is modulated by the digital audio signal through A/D converters 13a and 13b, an encoder 16, etc., and is recorded on a magnetic tape 23 together with the video signal. Consequently, the carrier of the audio signal has integer-fold frequency of the horizontal synchronizing signal in case of the monochromatic video signal as well as the line level of an error signal supplied to the VCO at the demodulation time is not changed by monochrome neither color, and stable demodulation is performed.

IPC: H04N5/08
Filed: 1990-03-27
Abstract: PURPOSE:To prevent a synchronizing signal from being phase shifted by turning on a switch within a synchronizing signal period and variably charging a coupling capacitor with electricity through a 1st bias means in accordance with the output potential of an inverted amplifier means. CONSTITUTION:A separated synchronizing signal is applied to a switch 14 as a control signal for turning on a switch 14 within the period of an L level and turning off the switch 14 within the period of an H level. Thereby, the capacitor 1 is charged by the capacitor corresponding to the shown voltage through 1st bias resistor 10 by turning on the switch 14 within the period of a synchronizing signal. When a composite video signal having a different APL is inputted, the value of the voltage V is changed in accordance with the difference of the APL and the charging capacity of the capacitor 1 is varied in accordance with each composite video signal. Namely, the voltage V is changed in accordance with each composite video signal, the capacitor 1 is charged in accordance with the voltage V and the DC bias of a point A is varied. Even if a composite video signal having a different APL is inputted, a separation level from the top level of a synchronizing signal is always fixed.
