PURPOSE:To control the working of a VTR at the record side and to attain the normal working of said VTR by supplying the switch signal produced from a switch signal producing means of a VTR at the reproduction side to a control means of the record side VTR. CONSTITUTION:The signals reproduced by the 1st and 2nd magnetic heads of a VTR1 at the reproduction side are supplied to a demodulation circuit 6 via a switch circuit 4 to be demodulated to original composite video signals and supplied to a VTR7 at the record side. The composite video signal is modulated again by a modulation circuit 12 to perform recording. Therefore, it is possible to secure the normal working of the VTR7 even in case the synchronizing signal is not reproduced in a normal way owing to the injuries given to a magnetic tape. |
