Abstract

Inventive systems and methods for remotely controlling infrared controlled devices by using addressed radio frequency control signals. Radio frequency signals propagate through most obstructions to infrared control signals. Augmenting each control signal with an address allows for great selectivity in an environment with several transmitters and receivers.

Claims

1. A method for transmitting an infrared control signal from a remote control to a controlled device, the method comprising:

(a) receiving an infrared control signal from a remote control device after a user has activated a remote control command;

(b) augmenting the IR signal by adding an identifying signal resulting in an augmented electronic signal, the identifying signal identifying a transmitter or a controlled device;

(c) converting the augmented electronic signal to a radio frequency signal;

(d) transmitting the radio frequency signal;

(e) receiving the radio frequency signal;

(f) wherein a-d are performed during a mode of operational control of the controlled device.

2. The method of claim 1, wherein receiving an infrared control signal comprises generating a first electronic signal according to the received infrared control signal.

3. The method of claim 2, wherein receiving an infrared control signal comprises retrieving a first identifying signal from a first code register.

4. The method of claim 2, wherein receiving an infrared control signal comprises storing the first electronic signal in association with a function of the controlled device.

5. The method of claim 4, wherein storing the first electronic signal in association with a function of the controlled device comprises retrieving a stored signal.

6. The method of claim 1, wherein the receiving the radio frequency signal comprises the step of detecting whether the identifying signal is present in the radio frequency signal.

7. The method of claim 1, wherein the step of receiving the radio frequency signal comprises generating an infrared control signal according to the radio frequency signal.

8. The method of claim 1, wherein receiving the radio frequency signal comprises transmitting the infrared control signal to the controlled device.

9. The method of claim 1, wherein receiving the radio frequency signal comprises generating a second augmented signal according to the received radio frequency signal.

10. The method of claim 9, wherein receiving the radio frequency signal comprises the step of retrieving a second identifying signal from a second code register.

11. The method of claim 10, wherein retrieving a second identifying signal from a second code register comprises determining the presence of the second identifying signal in the second augmented signal.

12. The method of claim 1, wherein, prior to receiving an infrared control signal, the method comprises storing the first and second identification signals in the first and second code registers respectively.

13. The method of claim 1, wherein storing the first identification signal in the first code register comprises storing of a plurality of first identification signals in the first code register.

14. The method of claim 13, wherein storing of a plurality of first identification signals in the first code register includes associating the stored first identification signals with controlled devices.

15. A method for transmitting an infrared control signal to a controlled device, comprising

(a) receiving an infrared control signal from a remote control device after a user has activated a remote control command;

(b) converting the received infrared control signal to a radio frequency signal;

(c) augmenting the radio frequency signal by adding an identifying signal resulting in an augmented radio frequency signal;

(d) transmitting the augmented radio frequency signal;

(e) receiving the augmented radio frequency signal;

(f) removing the identifying signal from the augmented signal;

(g) generating an infrared control signal according; and

(h) transmitting the infrared control signal to the controlled device,

wherein a-h are performed during a mode of operational control of the controlled device.

16. The method of claim 15, wherein receiving an infrared control signal comprises generating a first electronic signal according to the received infrared control signal.

17. The method of claim 16, wherein receiving an infrared control signal comprises retrieving a first identifying signal from a first code register.

18. The method of claim 16, wherein receiving an infrared control signal comprises storing the first electronic signal in association with a function of the controlled device.

19. The method of claim 18, wherein storing the first electronic signal in association with a function of the controlled device comprises retrieving a stored signal.

20. The method of claim 15, wherein the receiving the radio frequency signal comprises the step of detecting whether the identifying signal is present in the radio frequency signal.

21. The method of claim 15, wherein the step of receiving the radio frequency signal comprises generating an infrared control signal according to the radio frequency signal.

22. The method of claim 15, wherein receiving the radio frequency signal comprises transmitting the infrared control signal to the controlled device.

23. The method of claim 15, wherein receiving the radio frequency signal comprises generating a second augmented signal according to the received radio frequency signal.

24. The method of claim 23, wherein receiving the radio frequency signal comprises the step of retrieving a second identifying signal from a second code register.

25. The method of claim 15, wherein retrieving a second identifying signal from a second code register comprises determining the presence of the second identifying signal in the second augmented signal.

26. The method of claim 15, wherein, prior to receiving an infrared control signal, the method comprises storing the first and second identification signals in the first and second code registers respectively.

27. The method of claim 15, wherein storing the first identification signal in the first code register comprises storing of a plurality of first identification signals in the first code register.

28. The method of claim 27, wherein storing of a plurality of first identification signals in the first code register includes associating the stored first identification signals with controlled devices.
