Abstract

A method is provided providing position information. The method comprises sending, by a first device to a second device, via a real-time transmission protocol, a message specifying at least one position-related parameter associated with the second device. The method further comprises receiving, by the first device from the second device, via the real-time transmission protocol, the at least one position-related parameter.

Claims

1. A method for providing position information, the method comprising:

sending, by a first device to a second device, via a real-time transmission protocol, a message specifying at least one position-related parameter associated with the second device; and

receiving, by the first device from the second device, via the real-time transmission protocol, the at least one position-related parameter.

2. The method of claim 1, wherein the real-time transmission protocol is the Real-time Transport Protocol (RTP) specified in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3550.

3. The method of claim 2, wherein the at least one position-related parameter is transmitted in an RTP stream separate from an RTP video stream and separate from an RTP audio stream.

4. The method of claim 2, wherein the at least one position-related parameter is transmitted in a header extension of at least one of an RTP video stream or an RTP audio stream.

5. The method of claim 2, wherein the at least one position-related parameter is transmitted in an RTP Control Protocol (RTCP) feedback packet.

6. The method of claim 1, wherein the message is a Session Description Protocol (SDP) offer message.

7. The method of claim 1, wherein the at least one position-related parameter is at least one of:

longitude;

latitude;

altitude;

pan;

pan direction;

rotation;

tilt;

optical zoom;

or

digital zoom.

8. The method of claim 1, wherein the at least one position-related parameter is delivered in a multimedia telephony session.

9. The method of claim 1, wherein the at least one position-related parameter is delivered in a payload comprising a table of contents portion and a data portion, wherein the table of contents portion comprises a plurality of binary flags, the settings of the flags indicating the presence or absence of corresponding data elements in the data portion.

10. The method of claim 1, wherein a plurality of position-related parameters are separated by time offset values such that the position-related parameters are transmitted at intervals longer than intervals at which video data or audio data is transmitted.

11. A device, comprising:

a processor configured such that the device sends to a second device, via a real-time transmission protocol, a message specifying at least one position-related parameter associated with the second device, the processor further configured such that the device receives from the second device, via the real-time transmission protocol, the at least one position-related parameter.

12. The device of claim 11, wherein the real-time transmission protocol is the Real-time Transport Protocol (RTP) specified in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3550.

13. The device of claim 12, wherein the at least one position-related parameter is transmitted in an RTP stream separate from an RTP video stream and separate from an RTP audio stream.

14. The device of claim 12, wherein the at least one position-related parameter is transmitted in a header extension of at least one of an RTP video stream or an RTP audio stream.

15. The device of claim 12, wherein the at least one position-related parameter is transmitted in an RTP Control Protocol (RTCP) feedback packet.

16. The device of claim 11, wherein the message is a Session Description Protocol (SDP) offer message.

17. The device of claim 11, wherein the at least one position-related parameter is at least one of:

longitude;

latitude;

altitude;

pan;

pan direction;

rotation;

tilt;

optical zoom;

or

digital zoom.

18. The device of claim 11, wherein the at least one position-related parameter is delivered in a multimedia telephony session.

19. The device of claim 11, wherein the at least one position-related parameter is delivered in a payload comprising a table of contents portion and a data portion, wherein the table of contents portion comprises a plurality of binary flags, the settings of the flags indicating the presence or absence of corresponding data elements in the data portion.

20. The device of claim 11, wherein a plurality of position-related parameters are separated by time offset values such that the position-related parameters are transmitted at intervals longer than intervals at which video data or audio data is transmitted.

21. A method for providing position information, the method comprising:

sending, by a first device to a second device, via the Real-time Transport Protocol (RTP) specified in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3550, at least one position-related parameter associated with the first device, wherein the at least one position-related parameter is transmitted in at least one of;

an RTP stream separate from an RTP video stream and separate from an RTP audio stream;

a header extension of at least one of an RTP video stream or an RTP audio stream;

or

an RTP Control Protocol (RTCP) feedback packet.

22. The method of claim 21, wherein the at least one position-related parameter is specified in a Session Description Protocol (SDP) offer message sent to the first device from the second device.

23. The method of claim 21, wherein the at least one position-related parameter is at least one of:

longitude;

latitude;

altitude;

pan;

pan direction;

rotation;

tilt;

optical zoom;

or

digital zoom.

24. The method of claim 21, wherein the at least one position-related parameter is delivered in a multimedia telephony session.

25. The method of claim 21, wherein the at least one position-related parameter is delivered in a payload comprising a table of contents portion and a data portion, wherein the table of contents portion comprises a plurality of binary flags, the settings of the flags indicating the presence or absence of corresponding data elements in the data portion.

26. The method of claim 21, wherein a plurality of position-related parameters are separated by time offset values such that the position-related parameters are transmitted at intervals longer than intervals at which video data or audio data is transmitted.
