Abstract

PURPOSE:To ensure the both reproduction for the signals of different systems, just by adding the switching means effectively to the record/reproduction signal process means of one signal. CONSTITUTION:At the reproduction time of the PAL signal, horizontal synchronous signal fH isolated from the reproduced video signal is applied to oscillator 27 and then led to frequency converter 28. The output of oscillator 29 is applied previously to the other input of converter 28, and thus continuous signal AP having the sum frequency of two input signals is delivered from converter 28 to be applied to frequency converter 17 of the reproduction side. On the other hand, the reproduced carrier chrominance signal, i.e., the output of BPF18 is applied to burst gate unit 31; and the frequency and the phase of this burst signal are synchronized with output signal fCP of oscillator 33. In the case of reproduction of the NTSC signal, signal AP having the sum frequency of output 40fH of oscillator 27 and output fCP of oscillator 24 is obtained from converter 28 to be applied to converter 17. At the same time, the output of unit 31 is applied to one input of phase comparator 23, and then the frequency and the phase of oscillator 24 are controlled with the output of unit 31.
