Abstract

PURPOSE:To improve the operability by connecting a television receiver and a device connected thereto by a 2-way bus line, detecting the connection state of each device at application of power for the television receiver and displaying only a character pattern of a device to be connected. CONSTITUTION:A control signal generating section 2-8 of a television receiver 2 and a control signal generating section 4-12 of a VTR are connected by a 2-way bus line. When a television power supply is turned on and the power rises, a control signal turning on the power of a VTR is outputted through the 2-way bus line, and when a reply signal from the VTR is received by the television receiver within a prescribed time, it is discriminated as 'connection' and when no reply signal is received after a prescribed time elapses, it is discriminated to be 'unconnection', and the result is stored in a storage means of a control signal generation section 2-8. The similar control is applied to a VHD player, a BS tuner and a character multiplex adaptor and each connection state is stored in a storage means. Then the information stored in the storage means is read sequentially and only the character pattern of the devices stored as 'connection' is displayed on a screen of the television receiver.
