Abstract

PURPOSE: To constitute correct picture for the picture reproduced according to TV system, by providing the circuit which automatically discriminates various TV systems from the control signal and input signal recorded.
CONSTITUTION: The frequency of the first tape speed VP from the first oscillation source 1a of the reference oscillator 1 and that of the second tape speed VN from the second oscillation source 1b are fed to the tape speed control circuit 2 to control the servo system and the control signal from the oscillator 1 is fed to the comparator 5. Further, the control signal recorded on the tape is fed to the comparator 5, the frequency of the oscillator 1 and that of the control signal are compared at the comparator 5, and the signal of the color signal input 7 is selected at the gate circuit 6 depending on the result of comparison to discriminate the TV systems. When the frequency of the oscillation source 1a is reproduced in the speed VP, it is set lower than the frequency recorded in the speed VP and set higher than the frequency recorded in the speed VN. Further, when the frequency of the oscillation source 1b is reproduced at the speed VN, it is set lower than the frequency recorded in the speed VP and set higher than that recorded in the speed VN.
