PURPOSE:To use only one set of TV input terminals by connecting a VTR to an input terminal of an optical recording information reproducing device and a TV set to an output terminal and switching automatically a reproducing signal and a VTR signal depending on the presence of the reproduction operation thereby giving the result to the TV set. CONSTITUTION:A VTR 1 is connected to an input device 4 of an optical recording information reproducing device (VDP) 2 and a TV set 3 is connected to an output device 6. Moreover, a signal 9 of a reproducing device 7 such as a disk and a signal 11 of the VTR are given to a controller 5. Through the constitution above, the controller 5 interrupts the signal 11 when the reproducing device 7 is in the reproducing state to input the signal 9 to the TV set. Moreover, when the device 7 is not in the reproducing state, the controller 5 interrupts the signal 9 to input the signal 11 to the TV set 3. Thus, one set of input terminals is enough for the TV set. |
