Abstract

PURPOSE: To secure an automatic tuning for the tuner of the TV picture receiver to the channel of the modulated video signal sent from the VTR.
CONSTITUTION: In case the reproduced image of the VTR is viewed with connection secured between the TV picture receiver and the VTR, the VTR is put under the reproduction mode along with the connection secured between 5V and 5R of switch SW1. Output terminals 8V and 8R of SW2 are connected coupling to SW1, and control pulse PS has a high-level rise with control given to band memory 14. As a result, VHF tuner 12 features the low-channel reception mode for the VHF band, and flip-flop 25 is set. And the pulse generated from pulse generator 24 is supplied to counter 23 to start the sweep action. The synchronization of tuner 12 with the VTR channel is detected by broadcast signal detector circuit 27 to set flip-flop 25. Thus the pulse generation of generator 24 is stopped to secure the VTR reception mode.
