Abstract:
1. A control system comprising: a remote control apparatus that transmits a remote control signal via a wireless connection; and a controlled apparatus controlled by the remote control apparatus, wherein the controlled apparatus includes: a first input terminal to which a first external apparatus is connectable; a second input terminal to which a second external apparatus is connectable; a receiving unit constructed to receive the remote control signal from the remote control apparatus via the wireless connection; and a control unit constructed to (a) select one of the first input terminal and the second input terminal as an input source of the controlled apparatus based on the remote control signal, (b) check an operating state of the first external apparatus via the first input terminal after the first input terminal is selected as the input source of the controlled apparatus and before the controlled apparatus transmits a first control command corresponding to the remote control signal to the first external apparatus, (c) control the controlled apparatus to transmit the first control command to the first external apparatus via the first input terminal after the operating state of the first external apparatus is checked, (d) check an operating state of the second external apparatus via the second input terminal after the second input terminal is selected as the input source of the controlled apparatus and before the controlled apparatus transmits a second control command corresponding to the remote control signal to the second external apparatus, and (e) control the controlled apparatus to transmit the second control command to the second external apparatus via the second input terminal after the operating state of the second external apparatus is checked.
