Provided is a communication processing module, which is compatible with various kinds of devices to be operated by an operation input device. The communication processing module for the device to be operated receives any one of a standard operation signal specifying a standard action and a specific operation signal specifying an action unique to the device to be operated, which are transmitted by the operation input device. When the received operation signal is the standard operation signal, the communication processing module causes the device to be operated to execute an action corresponding to a content of the operation signal, and when the received operation signal is the specific operation signal, transfers data contained in the signal to a unique processing module. The unique processing module causes the device to be operated to execute an action corresponding to a content of the data transferred from the communication processing module.
