Abstract

An intelligent pairing between a first device and a target second device is described. The intelligent pairing can use information provided by a plurality of second devices responding to a connection request by the first device where only one of the plurality of responding second devices is the target second device. The information can include a motion signature, a first device identifier, and a second device identifier.

3. The method as recited in claim 2, wherein the shared information is at least one of the following:

a list that includes at least one preferred personal media device identifier (PMD_ID), an input command pattern, information related to current proximity of the first device and the second device, a list that includes at least one PMD_ID corresponding the PMD recently paired with a target SD, a preferred PMD_ID, and a preferred sport device identifier (SD_ID).

4. The method as recited in claim 1, wherein the shared information is motion data.

5. The method as recited in claim 4, further comprising:

generating the motion data by,

mechanically associating the first device and the second device;

moving the first device and second device such that first device and the second device experience essentially the same movements;

recording the movements of the first device as first device motion data and the movements of the second device as second device motion data;

associating a first time stamp with the first device motion data and a second time stamp with the second device motion data, the time stamps indicating concurrency of the movements of the first device and second device; and

retaining the first device motion data as a first device motion signature in the first device and the second device motion data as a second device motion signature in the second device.

6. The method as recited in claim 5, further comprising:

using the first motion signature and the second motion signature to subsequently pair the first device and the second device.

7. The method as recited in claim 6, further comprising:

broadcasting a pairing request by the first device, the pairing request including at least a request for a motion signature;

receiving the motion signature from a responding second device;

comparing the received motion signature to the motion signature retained in the first device; and

pairing the first device and the responding second device when the received motion signature effectively matches the motion signature retained in the first device.

8. The method as recited in claim 7, further comprising:

comparing the first and the second time stamps when the comparing indicates that the received motion signature does not effectively match the motion signature retained in the first device; and

pairing the first device and the second device when the comparing of the first and the second time stamps indicates that the received motion signature and the motion signature retained in the first device were created concurrently with each other.

9. The method as recited in claim 5 wherein the mechanically associating the first device and the second device comprises:

holding the first device in a first hand; and

concurrently holding the second device in a second hand different from the first hand.

10. A portable media device, comprising:

a processor, wherein the processor causes the portable media device to pair with a target remote device by causing the portable media device to,

receive connection packets from each of a plurality of remote devices only one of which is the target remote device, wherein each of the connection packets includes information associated with the corresponding remote device,

analyze the received information;

identify the target remote device based on the analysis; and

pair only with the target remote device.

11. The portable media device as recited in claim 10, wherein the portable media device further comprises:

a wireless interface arranged to transmit and receive wireless signals.

12. The portable media device as recited in claim 10, wherein the portable media device is not wireless capable, the portable media device being electrically connected to a wireless capable external circuit arranged to transmit and receive the wireless signals.

13. The portable media player as recited in claim 11, further comprising:

a motion detector, the motion detector arranged to detect motion of the portable media device, the motion detector converting the detected motion into motion data retained in the memory device, wherein during a shake to pair pairing operation between the portable media player and the target remote device the portable media player and the target remote device are mechanically associated with each other such the both the portable media player and the target remote device undergo essentially the same movement that the motion detector senses and converts to motion data, the motion data retained in the memory device as a portable media player motion signature.

14. The portable media player as recited in claim 12, wherein after the wireless link is established, the portable media player forwards a copy of the portable media player motion signature to the target remote device that the target remote device retains as a target remote device motion signature.

15. The portable media player as recited in claim 13, wherein during a subsequent pairing, the portable media player receives a remote device motion signature and uses the remote device motion signature to identify the target remote device.

16. The portable media player as recited in claim 14, wherein the portable media player uses the remote device motion signature to identify the target remote device by comparing the received remote device motion signature with the received remote device motion signature.

17. The portable media player as recited in claim 15, wherein the comparing indentifies the target remote device when the comparing indicates that the received remote device motion signature essentially matches the motion signature retained in the personal media device.

19. The method as recited in claim 17, wherein the first device is a personal media device (PMD) and wherein the second device is a sport device(SD), the sport device including at least one sensor.

21. The computer readable medium as recited in claim 10, wherein the shared information is a motion signature.

18. Non-transitory computer readable medium for storing computer code executed by a processor in a portable device for pairing with a target remote device, comprising:
