ABSTRACT:
In a remote control system, when a user directs a host device of a portable type toward target devices for search and specification, a search signal including a unique identifier (UID) is transmitted from a directional antenna. Each of the target devices stores the UID included in the received search signal in a memory unit, and transmits a response signal including device information on itself from an antenna. The host device identifies one of the target devices based on the device information included in the response signal, runs a control program for the identified target device, and displays an operation screen on a display unit. When the user instructs the remote operation on the operation screen, the host device transmits a remote control signal including the UID from the omni-directional antenna. When the target device receives the remote control signal including the UID that matches with the UID stored in the memory unit, the target device controls a function unit according to the remote control signal.
