Abstract
PURPOSE: To enable to perform special reproduction such as still reproduction in excellent manner, by identifying the reproduction signal in the field reproduction system and performing different type opposite signal processing in case of failure.
CONSTITUTION: Carrier chrominance signal only is separated at BPF5, and further it is converted into two types of low band conversion carrier signals and fed to the adder 9. They are added with FM modulation luminance signal and fed to the magnetic head 10. Further, the chrominance signals of two types above are alternately produced at every truck. When this is reproduced in the field reproduction system, it is identified at the circuit consisting of the amplitude detector 25, and reference voltage source 24, and in case of failure, i.e., opposite signal processing different at recording, different type opposite signal processing is made. Thus, since normal reproduction signal is obtained at all times, special reproduction can be made in excellent manner.
