Patent ID: 8281047

Claim:
An electronic device comprising: an information setting unit that sets information of a controlled device; a control signal converting unit that converts, when a control signal in a first format is a control signal for the controlled device for which the information has been set by the information setting unit, the control signal into a control signal in a second format; a control signal sending unit that sends the control signal in the second format, which is converted by the control signal converting unit, to the controlled device; a control signal receiving unit that receives the control signal in the first format from an external device; a video signal sending unit that sends a video signal as a differential signal to the external device by using a plurality of channels via a transmission path; and a video signal receiving unit that receives, from the controlled device, a video signal as a differential signal by using a plurality of channels via a transmission path, wherein the control signal receiving unit receives the control signal in the first format from the external device via a control data line constituting the transmission path, and wherein the control signal sending unit sends the control signal in the second format to the controlled device via a bidirectional communication channel constituted by predetermined lines of the transmission path, wherein the electronic device determines a logical address for the controlled device in response to a user input, and the logical address is determined on the basis of a table cross-referencing device types to logical addresses, wherein after the electronic device determines a logical address for the controlled device, the electronic device notifies the external device that a physical address corresponding to the logical address is associated with a Consumer Electronics Control (CEC)-compliant device.
