Abstract

Upon receiving a keystroke indicator signal from a remote control device, a key code generator device identifies a codeset usable to communicate with a selected consumer device. The keystroke indicator signal contains an indication of a pressed key, which corresponds to a function of the selected consumer device. Using the identified codeset and the key indication, the key code generator device generates a key code and modulates that key code onto a radio frequency carrier signal, thereby generating a first key code signal. The remote control device receives the first key code signal from the key code generator device and modulates the key code onto an infrared frequency carrier signal, thereby generating a second key code signal. The remote control device relays the key code to the selected consumer device in the second key code signal. The key code causes the selected consumer device to perform the desired function.

First claim

What is claimed is:

1. A first device for transmitting a command to control a functional operation of a second device, the first device comprising:
a receiver;
a transmitter;
a processing device coupled to the receiver and the transmitter; and
a memory storing instructions executable by the processing device, the instructions causing the processing device to:
generate a key code using a keystroke indicator received from a third device in communication with first device via use of the receiver, the keystroke indicator having data that indicates an input element of the third device that has been activated;
format the key code for transmission to the second device; and
transmit the formatted key code to the second device in a key code signal via use of the transmitter;
wherein the generated key code comprises a one of a plurality of key code data stored in a codeset, wherein the one of the plurality of key code data is selected from the codeset as a function of the keystroke indicator received from the third device, wherein each of the plurality of key code data stored in the codeset comprises a series of digital ones and/or digital zeros, and wherein the codeset further comprises time information that describes how a digital one and/or a digital zero within the selected one of the plurality of key code data is to be represented in the key code signal to be transmitted to the second device.

2. The first device as recited in claim 1 , wherein the receiver comprises an RF receiver.

3. The first device as recited in claim 1 , wherein the transmitter comprises an IR transmitter.

4. The first device as recited in claim 1 , wherein the formatted key code is transmitted from the first device to the second device via a wired connection between the first device and the second device.

5. The first device as recited in claim 1 , wherein the formatted key code is transmitted from the first device to the second device via a wireless connection between the first device and the second device.

6. The first device as recited in claim 1 , wherein the first device comprises a further receiver for receiving a media from a fourth device in communication with the first device and wherein the first device is coupled to the second device to provide the media to the second device for display on a display device associated with the second device.

7. The first device as recited in claim 1 , wherein the generated key code controls at least one of a power on, power off, volume up, and volume down functional operation of the second device.

8. The first device as recited in claim 1 , wherein the first device comprises a further receiver for receiving the codeset from a fourth device in communication with the first device.

9. A first device for transmitting a command to control a functional operation of a second device, the first device comprising:
a receiver;
a first transmitter;
a second transmitter;
a processing device coupled to the receiver, the first transmitter, and the second transmitter; and
a memory storing instructions executable by the processing device, the instructions causing the processing device to:
generate a key code using a keystroke indicator received from a third device in communication with first device via use of the receiver, the keystroke indicator having data that indicates an input element of the third device that has been activated;
format the key code for transmission to the second device;
transmit the formatted key code to the second device in a key code signal via use of the first transmitter and a first communication protocol; and
transmit the formatted key code to the second device in a keycode signal via use of the second transmitter and a second communication protocol when it is determined that the second device is not responsive to the key code signal transmitted via use of the first transmitter and the first communication protocol.

10. The first device as recited in claim 9 , wherein one of the first and second transmitters comprises an IR transmitter and wherein the other of the first and second transmitter comprises an RF transmitter.

11. The first device as recited in claim 9 , wherein one of the first and second communication protocols comprises a wired communication protocol and the other of the first and second communication protocols comprises a wireless communication protocol.

12. The first device as recited in claim 9 , wherein the formatted key code is transmitted from the first device to the second device via a wired connection between the first device and the second device.

13. The first device as recited in claim 9 , wherein the receiver comprises an RF receiver.

14. The first device as recited in claim 9 , wherein the first device comprises a further receiver for receiving a media from a fourth device in communication with the first device and wherein the first device is coupled to the second device to provide the media to the second device for display on a display device associated with the second device.

15. The first device as recited in claim 9 , wherein the generated key code controls at least one of a power on, power off, volume up, and volume down functional operation of the second device.

16. The first device as recited in claim 1 , wherein the first device comprises a further receiver for receiving at least one codeset from a fourth device in communication with the first device and wherein the at least one codeset is used to generate the key code.
