Abstract

A method for establishing a paired connection between first and second media devices across a network includes transmitting a first information message across the network including an identifier that includes a request to pair the first and second media devices. When a second information message is received from the second media device within a first predetermined time period, the first device retrieves an identifier of the second device and transmits a confirmation message across the network including the device identifiers. A paired connection between the media devices is completed after a corresponding confirmation message from the second device is received within a second predetermined time period.

Claims

1. A method for establishing a paired connection between first and second media devices across a network, comprising:

responsive to user interaction with the first media device, transmitting a first information message across the network including an identifier that includes a request to pair the first media device with the second media device;

responsive to receipt of a corresponding confirmation message from the second device within a second predetermined time period, completing a paired connection with the second device, said connection employing a communications protocol which permits the first device to control the second device in providing a media acquisition, filtering or output service, or combinations thereof.

2. A method according to claim 1, wherein one or more of the information and confirmation messages are transmitted via User Datagram Protocol.

3. A method according to claim 1, wherein said first and second time periods are substantially the same.

4. A method according to claim 1, wherein said first media device is responsive to receipt of an information message from a third media device, different from said second media device, upon failing to establish said paired connection with said second device during said first predetermined time period.

5. A method according to claim 1, wherein said first media device is responsive to receipt of a confirmation message from a third media device, different from said second device, upon failing to establish said paired connection with said second media device during said second predetermined time period.

6. A method according to claim 1, further comprising establishing one or more further paired connections with further media devices.

7. A method according to claim 1, wherein each of said information and confirmation messages includes a protocol identifier.

8. A method according to claim 1, further comprising communicating according to the Picture Transfer Protocol (PTP).

9. A method according to claim 1, wherein at least one of the first and second devices comprises a digital camera.

10. A method according to claim 9, wherein at least one of the first and second devices comprises a printer.

11. A method according to claim 1, wherein upon receipt of said first message and actuation of a switch, said second device automatically generating and transmitting said second message.

12. A method according to claim 1, wherein upon receipt of said second message and actuation of a switch, said first device automatically generating and transmitting said confirmation message.

14. A device according to claim 11, further comprising a microprocessor or one or more other general purpose computing device components, printer architecture, digital image acquisition device architecture, or an adapter, or combinations thereof.

15. A device according to claim 14, wherein the network interface comprises an Internet Protocol (IP) transport interface.

16. A device according to claim 15, wherein the network interface comprises a Wireless Local Area Network interface, a Bluetooth interface, or an Ethernet interface interface, or combinations thereof.

17. A device according to claim 14, further comprising an adapter that includes a bus interface for communicating with said network interface upon establishment of said paired connection.

18. A device according to claim 17, wherein said bus interface comprises a USB interface.

19. A device according to claim 17, wherein the adapter further comprises a PTP initiator module for communication with a PTP compliant device across said bus interface.

20. A device according to claim 19, further comprising a PTP responder module for communication with one or more PTP/IP compliant devices through said network interface.

21. A device according to claim 20, further for establishing one or more further paired connections with respective devices.

22. A device according to claim 21, further for establishing respective PTP sessions with each device for which a paired connection has been established through said network interface.

23. A device according to claim 22, wherein said device acts as a bridge when a paired connection has been established with only one device.

24. A device according to claim 22, wherein said device acts as a gateway when more than one paired connection has been established.

25. A device according to claim 14, the device comprising a digital camera.

26. A device according to claim 25, wherein the second device comprises a printer.

27. A device according to claim 14, wherein upon receipt of said first message and actuation of a second pairing actuator associated with said second device, said second device automatically generating and transmitting said second message.

28. A device according to claim 14, wherein upon receipt of said second message and actuation of said pairing actuator, said first device automatically generating and transmitting said confirmation message.

13. A media device for handling media and establishing a paired connection with a second media device across a network, comprising:

a media device housing containing a media handling component architecture;

a network interface coupled with the component architecture; and
