Abstract

Provide are a method and device for exchanging endpoint information and a telepresence endpoint. The method includes that: multiplexing information is exchanged between telepresence endpoints. By means of the present disclosure, the problem in the related art that there are too many ports and multiplexing transmission is unsmooth due to the fact that a multiplexing transmission mode of a traditional session system is still adopted in a telepresence system based on a conventional protocol architecture is solved, and the effect of exchanging the multiplexing information between the telepresence endpoints and therefore multiplexing can be successfully performed in the telepresence system is further achieved.

First claim

What is claimed is:

1. A method for exchanging endpoint information, comprising:
telepresence endpoints exchanging multiplexing information:
wherein the multiplexing information comprises multiplexing mapping information used for describing a mapping relationship between a media capture code stream and a transmission code stream;
wherein the telepresence endpoints exchange the multiplexing mapping information in at least one of the following manners: in a signalling exchange process, the telepresence endpoints exchanging the multiplexing mapping information by carrying the multiplexing mapping information in signalling information; and when transmitting a media stream, the telepresence endpoints exchanging the multiplexing mapping information by carrying the multiplexing mapping information at an extended header of the transmitting media stream.

2. The method as claimed in claim 1 , wherein the multiplexing information further comprises at least one of:
multiplexing indication information used for indicating whether a telepresence endpoint adopts multiplexing; and
multiplexing type information used for indicating a multiplexing type by which the multiplexing mapping information is exchanged.

3. The method as claimed in claim 2 , wherein the telepresence endpoints exchange the multiplexing indication information in at least one of following manners:
the telepresence endpoints exchanging the multiplexing indication information when the telepresence endpoints are exchanging a terminal capability set; and
the telepresence endpoints exchanging the multiplexing indication information when the telepresence endpoints are setting up a call.

4. The method as claimed in claim 2 , wherein the telepresence endpoints exchange the multiplexing type information in at least one of following manners:
the telepresence endpoints exchanging the multiplexing type information when the telepresence endpoints are exchanging a terminal capability set; and
the telepresence endpoints exchanging the multiplexing type information when the telepresence endpoints are setting a call.

5. The method as claimed in claim 1 , after the telepresence endpoints exchanging the multiplexing information, the method further comprising:
performing multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

6. A device for exchanging endpoint information, applicable to telepresence endpoints, comprising:
an exchanging component, configured to exchange multiplexing information:
wherein the multiplexing information comprises multiplexing mapping information used for describing a mapping relationship between a media capture code stream and a transmission code stream;
wherein the exchanging component comprises at least one of: a fifth exchanging element, configured to, in a signalling exchange process, exchange multiplexing mapping information by carrying the multiplexing mapping information in signalling information; and a sixth exchanging element, configured to, when transmitting a media stream, exchange the multiplexing mapping information by carrying the multiplexing mapping information at an extended header of the transmitting media stream.

7. The device as claimed in claim 6 , wherein the exchanging component comprises at least one of:
a first exchanging element, configured to exchange multiplexing indication information comprised in the multiplexing information when exchanging a terminal capability set; and
a second exchanging element, configured to exchange multiplexing indication information comprised in the multiplexing information when setting up a call.

8. The device as claimed in claim 6 , wherein the exchanging component comprises at least one of:
a third exchanging element, configured to exchange multiplexing type information comprised in the multiplexing information when exchanging a terminal capability set; and
a fourth exchanging element, configured to exchange multiplexing type information comprised in the multiplexing information when setting up a call.

9. The device as claimed in claim 6 , further comprising:
a transmitting component, configured to perform multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

10. A telepresence endpoint, comprising the device as claimed in claim 6 .

11. The method as claimed in claim 2 , after the telepresence endpoints exchanging the multiplexing information, the method further comprising:
performing multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

12. The method as claimed in claim 3 , after the telepresence endpoints exchanging the multiplexing information, the method further comprising:
performing multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

13. The method as claimed in claim 4 , after the telepresence endpoints exchanging the multiplexing information, the method further comprising:
performing multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

14. The method of as claimed in claim 1 , after the telepresence endpoints exchanging the multiplexing information, the method further comprising:
performing multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

15. The device as claimed in claim 7 , further comprising:
a transmitting component, configured to perform multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

16. The device as claimed in claim 8 , further comprising:
a transmitting component, configured to perform multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.

17. The device as claimed in claim 6 , further comprising:
a transmitting component, configured to perform multiplexing transmission on a media stream according to a result of exchanging the multiplexing information.
