PURPOSE:To eliminate a crosstalk component between adjacent trunks and realize a TV camera plus VTR system with small-sized and weight, light, by divising a vertical correlation for a doubled horizontal scanning period between a selected reproduced chrominance signal and that which is delayed by said period. CONSTITUTION:A color TV camera 1' is of the single carrier separation system and composed mainly of an image pickup optical system 4, an image pickup tube 5, a pre-amplifier 6. A VTR 2' of of the FM guard bandless recording system by reducing conversion single carrier of 2-head helical scanning and composed mainly of the 1st and 2nd magnetic heads 19a and 19b, a record reproduction switching circuit 18, and a phase shifting circuit 23. A standard signalization converting circuit 35 is connected to the VTR 2' through a reproducing circuit 28 having a switcher 30, and a color demodulating circuit 10, an encoder 11, etc., are installed to the circuit 35. A monitor TV 3 is connected to the output of the encoder 11. By installing the circuits 28 and 35, crosstalk components between adjacent trunks are eliminated and a TV camera plus VTR system with small-sized and weight light is realized. |
