Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
279 words
A remote control system for commanding at least one predetermined function in a slave unit, the system comprising: a user-operable remote control unit for effecting a controlled function in at least one slave unit; a master control unit having means for generating a unique identification code and for communicating the identification code to the user-operable remote control unit and to said at least one slave unit; the remote control unit having means for receiving and storing the identification code communicated from the master control unit, means for generating a remote operating signal that includes a function code for executing a user-requested function and the stored ID code, and means for transmitting the remote operating signal over a first communications pathway to said at least one slave unit; the said at least one slave unit having a first means for receiving the remote operating signal including the identification code and a functional code from the remote control unit via the first communications pathway and having a second means for receiving the identification code from the master control unit via a second communications pathway, the slave unit having means for storing the identification code received via the second communications pathway and for collating the stored identification code with the identification code received via the first communications pathway, the slave unit executing the function commanded by the function code upon successful collation of the identification code received via the first communications pathway and the stored identification code received via the second communications pathway; the master unit providing another unique identification code to the remote control unit and to the slave unit as a function of the use of the remote control unit.
Claim 2
Dependent Claim
279 words
A remote control system for commanding at least one predetermined function in a slave unit, the system comprising: a user-operable remote control unit for effecting a controlled function in at least one slave unit; a master control unit having means for generating a unique identification code and for communicating the identification code to the user-operable remote control unit and to said at least one slave unit; the remote control unit having means for receiving and storing the identification code communicated from the master control unit, means for generating a remote operating signal that includes a function code for executing a user-requested function and the stored ID code, and means for transmitting the remote operating signal over a first communications pathway to said at least one slave unit; the said at least one slave unit having a first means for receiving the remote operating signal including the identification code and a functional code from the remote control unit via the first communications pathway and having a second means for receiving the identification code from the master control unit via a second communications pathway, the slave unit having means for storing the identification code received via the second communications pathway and for collating the stored identification code with the identification code received via the first communications pathway, the slave unit executing the function commanded by the function code upon successful collation of the identification code received via the first communications pathway and the stored identification code received via the second communications pathway; the master unit providing another unique identification code to the remote control unit and to the slave unit as a function of the use of the remote control unit.
Claim 3
Dependent Claim
14 words
The remote control system of claim 1 wherein the second pathway is wire cable.
Claim 4
Dependent Claim
15 words
The remote control system of claim 1 wherein the first pathway is an infrared pathway.
Claim 5
Dependent Claim
38 words
The remote control system of claim 1 wherein the master unit provides another unique identification code to the remote control unit and to the slave unit as a function of each successive use of the remote control unit.
