<p>PURPOSE:To automatically synchronize a video signal with a voice signal by writing a control signal in a voice track of a video tape recorder (VTR) for a prescribed time and muting a digital voice signal to be supplied to a digital voice signal recording/reproducing device (DAT) at the time of recording. CONSTITUTION:When an operation key 25 is depressed, a control signal from a control signal generating circuit 27 is recorded in a voice signal track on the VTR 3 for a prescribed time through a timer control circuit 26 and a timer 24. On the other hand, a digital I/O circuit 23 is controlled through the timer 24 to mute only the voice data of a digital signal supplied to the DAT 4 for a prescribed time. Consequently, the DAT 4 automatically records a start ID signal. At the time of reproducing, the VTR 3 detects a control signal by a control signal detecting circuit 28, and after a prescribed time releases the play pause state of the DAT 4 by a DAT control circuit 29 through the circuit 6 and the timer 24. Consequently, the VTR 3 can be automatically synchronized with the DAT 4.</p> |
