A device control is disclosed for controlling a device with a high-priority signal without interference by a low-priority signal. Panel keys, which serve as a high-priority signal receiver unit, receives a high-priority signal. A panel key signal processing unit, which is a high-priority signal processing unit, processes the signal received by the panel keys. A remote control signal receiver unit, which is a low-priority signal receiver unit, receives a low-priority signal. A remote control signal processing unit, which is a low-priority signal processing unit, processes the signal received by the remote control signal receiver unit. A remote control signal reception control unit, which is a low-priority signal processing control unit, disables the processing in the remote control signal processing unit when the panel key signal processing unit is performing the processing.
