Abstract

Methods and systems for pairing remote controls to video or audio components are provided. The remote control, for example, may include, but is not limited to, an ultrasound receiver and a controller coupled to the ultrasound receiver. The controller may be configured to receive an ultrasound signal from the ultrasound receiver, extract pairing data from the ultrasound signal, and configure the remote control based upon the pairing data.

Claims

1. A remote control, comprising:

an ultrasound receiver; and

a controller coupled to the ultrasound receiver, the controller configured to;

receive an ultrasound signal from the ultrasound receiver;

extract pairing data from the ultrasound signal; and

configure the remote control based upon the pairing data.

2. The remote control of claim 1, wherein when multiple ultrasound signals are detected by the ultrasound receiver, the controller is further configured to:

select one of the multiple ultrasound signals with the highest signal strength;

extract the pairing data from the selected ultrasound signal; and

configure the remote control based upon the pairing data extracted from the selected ultrasound signal.

3. The remote control of claim 1, further comprising:

a pairing control interface coupled to the controller; and

an ultrasound transmitter coupled to the controller,

wherein the controller is further configured to cause the ultrasound transmitter to output an ultrasound pairing request signal in response to an input to the pairing control interface.

4. The remote control of claim 3, wherein the controller, after causing the ultrasound transmitter to output the ultrasound pairing request signal is further configured to cause the ultrasound receiver to sweep for ultrasound signals for a predetermined period of time.

5. The remote control of claim 1, wherein the controller is further configured to decode the pairing information from encoded pairing information contained in the ultrasound signal.

6. The remote control of claim 2, further comprising:

a memory coupled to the controller,

wherein the controller is further configured to;

compare the extracted pairing data with pairing data stored in the memory, and

replace, if the extracted pairing data is different than the pairing data stored in the memory, the pairing data stored in the memory with the extracted pairing data, and

configure the remote control based upon the pairing data stored in the memory.

7. A method of pairing a remote control having a processor and an ultrasound receiver to a video or audio component comprising

monitoring, by the ultrasound receiver, for one or more ultrasound signals;

selecting, by the processer, the ultrasound signal with the highest signal strength from the one or more ultrasound signals;

extracting, by the processer, paring data from the selected ultrasound signal; and

pairing, by a processer, the remote control to the video or audio component using the pairing data.

8. The method of claim 7, wherein when the pairing data is encoded, the extracting further comprises decoding the pairing data using a key stored in a memory.

9. The method of claim 7, further comprising:

transmitting an ultrasound signal requesting pairing information from the video or audio component; and

initiating, by the controller, the sweeping after the ultrasound signal requesting pairing information has been transmitted.

10. The method of claim 7, further comprising initiating the sweeping when power is supplied to the remote control.

11. The method of claim 7, further comprising storing the pairing data in a memory.

12. The method of claim 11, further comprising:

comparing the extracted pairing data with pairing data stored in the memory,

replacing, if the extracted pairing data is different than the pairing data stored in the memory, the pairing data stored in the memory with the extracted pairing data, and

configuring the remote control based upon the pairing data stored in the memory.

13. The method of claim 7, further comprising:

transmitting, by an ultrasound transmitter coupled to the video or audio component, an ultrasound signal including pairing data.

14. The method of claim 13, wherein the pairing data is transmitted using bursts of ultrasound.

15. The method of claim 13, wherein the transmitting is continuous whenever power is supplied to the video or audio component.

16. The method of claim 13, wherein the transmitting occurs for a predetermined period of time in response to a pairing request.

17. The method of claim 13, wherein the video or audio component encodes the transmitted pairing data.

18. An entertainment device, comprising:

an ultrasound transmitter; and

a controller electrically coupled to the ultrasound transmitter, wherein the controller is configured to cause the ultrasound transmitter to output an ultrasound signal including pairing data associated with the entertainment device.

19. The entertainment device of claim 18, further comprising a network interface coupled to the controller, wherein the controller is further configured to communicate with other entertainment devices using the network interface to coordinate which frequency of ultrasound signal each video or audio component will transmit.

20. The entertainment device of claim 18 further comprising:

an ultrasound receiver coupled to the controller,

wherein the controller is further configured to cause the ultrasound transmitter to output the ultrasound signal in response to receiving a pairing request through the ultrasound receiver.
