  • Patent number: 5272574
    Abstract: A circuit for concurrently recording at least two picture signals, each received from at least two different desired television broadcasting channels, on a single video tape in a video tape recorder, and for concurrently reproducing at least two picture signals from a single video tape on which at least two different television broadcasting channels are recorded, in a video tape recorder provided with such video tape. First and second vertical synchronization detection circuits 104, 105 detect each vertical synchronization signal from first and second video signal input terminals VD1, VD2. A recording controller 106 receives the vertical synchronization signals that are detected by the first vertical synchronization detection circuit I04 and the second vertical synchronization signal detection circuit 105, and therefrom produces a first memory control signal, a first mixing control signal and a first selection control signal.
