ABSTRACT:
To prevent, cross-talk and other signals from being applied from the magnetic transducer head (6, 7) to an output circuit (12, 13; 28, 29) in a video tape reproduction system, in which one of the heads, only, is in contact with the tape, and the other head runs free, a synchronizing signal recognition stage, responding to the first appearance of a synchronizing signal at one of the heads, is connected to control a switch, typically an electronic switch, to transmit the signals from the specific head to the output circuit and disable signal transfer of any signals from the other one of the heads since those signals, usually, would be noise or disturbance signals. When a synchronizing signal, then, is received from the other head, which previously was disconnected, the circuit switches over to disable the first one and transmit only signals from the second head, so that electronic switching is provided based on recognition of signals transduced from the tape itself, typically and preferably synchronizing words in a digitally recorded TV signal.
