PURPOSE:To realize excellent digital record reproduction while an input and output terminals are connected, by performing switching operations between the input and output terminals of TV signals of a processor and the output and input terminals of TV signals of a VTR is accordance with the ON/OFF condition of the power supply for the PCM processor. CONSTITUTION:When the power switch S of a PCM processor 51 is turned on, the output terminal VIDEO-OUT and input terminal VIDEO-IN of a VTR are correspondingly connected electrically to the input terminal of the reproducing system 512 of a processor 51 and the output terminal of the recording system 511 of the processor 51 via a relay and switch, respectively. When the switch S is turned off, the input terminal VIDEO-INM and output terminal VIDEO-OUTR of a TV receiver are electrically connected to the output terminal VIDEO-OUT and input terminal VIDEO-IN of the VTR through the relay and switch. Therefore, the VTR can make video recording and reproduction together with the TV receiver and no redoing of the connection between them is required. |
