ABSTRACT:
A remote operating system including a remote operating device 20 having the transmitting/receiving function and a learning function, a slave unit 30 provided in any of a variety of main body members of the electronic equipment remote-operated by the remote operating device, and a master unit 10 for the slave unit. An identification code generating circuit 11 of the master unit 10 generates an identification code as the identification information. The master unit 10 transmits the identification code from a transmitter 13 to the remote controlling unit 20 by an IR beam, while transmitting the identification code from a sender/receiver 14 over a cable to the slave unit 30. The remote operating unit 20 appends the identification code associated with an operating switch 21 to form a remote operating signal which is transmitted to the slave unit 30. The slave unit 30 collates the identification code contained in the remote controlling signal to the identification code transmitted over the cable and stored in a storage unit 34. With the remote operating system, security in remote control may be improved.
