A control signal converting unit(130) comprises the followings. A device recognizing unit(410) recognizes product information of home appliances. A wireless network interface unit is for configuring a WPAN with an integrated remote controller. A processor unit(420) transmits home appliance product information, recognized by the device recognizing unit, to the integrated remote controller through the network interface unit. After that, the processor unit performs a control operation so as to convert a wireless network control message, transmitted from the integrated remote controller, into an infrared signal based on a control profile. An infrared signal transmitting unit(440) converts the wireless network control message into an infrared signal by the control of the processor unit, and transmits the converted signal to the home appliance.
