The present invention provides for controlling a controlled apparatus, which is controlled by a remote control signal. The remote control signal transmitted from a remote control apparatus is received, and the controlled apparatus or a second controlled apparatus is selected according to the remote control signal. A control command corresponding to the remote control signal is transmitted to the second controlled apparatus, if the second controlled apparatus is selected. An operating state of the second controlled apparatus is checked before the control command is transmitted to the second controlled apparatus. The controlled apparatus is controlled according to the remote control signal, if the controlled apparatus is selected.
