Abstract
PURPOSE: To increase the storage capacity of video and information signals by frequency dividing and multiple recording the video signal and the information signal associated to this in a VTR for administration of going in and out in buildings.
CONSTITUTION: Luminance signal SY is separated 1 from the composite color video signal SO from a TV camera. The SYM signal after FM modulation 2 is inputted to a synthesizer 8 via BPF 3. Carrier color signal Sc is extracted 5 from the signal SO and is converted 7 to the signal SCM having a sub-carrier fCN having undergone low frequency conversion. After this signal is synthesized 18 with the information signal SD associated to the signal SO, it is inputted to the synthesizer 8. The resultant composite color video signal SOM is recorded through heads HA, HB. In this case the information code signal PD from an encoder 11 is led out as the signal SD by the same frequency signal SCH as that of the sub-carrier having undergone low frequency conversion and the signal SD is frequency separated and multiplexed to the signal SYM.
