Title: Video signal switching circuit
Inventor: NAKANO MASAHIKO
IPC: H04N5/44
Filed: 1982-08-09
Abstract: PURPOSE:To make the operation easy and to prevent mis-operation, by constituting the circuit that a video signal of a source having a predetermined or a desired priority is displayed automatically on a TV receiver with the operation only from the source side. CONSTITUTION:In applying a power supply of the TV receiver, a switching transistor(TR) T30 of an initial set circuit I is turned on to turn on a set terminal of a TV control circuit C1. A reset terminal 4 of the circuit C1 goes to H and a TV switch S1 turns on, because an H output is produced from an output terminal 13. On the other hand, the level of output terminals 9, 10 go to L, because set terminals 7, 11 of a VTR control circuit C2 and a disc control circuit C3 are grounded respectively with diodes D11, D12 via TRT30. Thus, since switches S2, S3 of the VTR and the disc are both kept turned off, only na output of the TV switch S1 is displayed finally on the TV receiver. Further, the same processing is performed for the VTR and disc.

Thus, the base potential of the bipolar TR 50 reaches a prescribed voltage higher by nearly 0.5-0.8V from the low level of an output terminal 2 and is not decreased up to a 2nd power supply VSS1. Thus, the increase in the leading time is suppressed and low power consumption is attained.
