Displaying a presenter during a video conference

1. A method comprising:

providing a user interface of a video conference between at least a first user and a second user, wherein the first user is associated with a first endpoint and the second user is associated with a second endpoint;

determining view rank values for each of the first endpoint and the second endpoint, wherein each view rank value indicates a likelihood that the user associated with the respective endpoint is speaking, wherein each view rank value is based at least one or more of a duration of speaking, a type of audio detected, a number of people who are in a room associated with the respective endpoint, a type of endpoint, a history of past video conferences, and whether at least one predetermined video function has been turned on; and

causing the user interface to display a first user video stream in a current presenter position and to display a second user video stream in a secondary presenter position based on the view rank values.

2. A method comprising:

providing a user interface of a video conference between at least a first user and a second user, wherein the first user is associated with a first endpoint and the second user is associated with a second endpoint;

determining view rank values for each of the first endpoint and the second endpoint; and

causing the user interface to display a first user video stream in a current presenter position and to display a second user video stream in a secondary presenter position based on the view rank values.

3. The method of claim 2 , further comprising collecting endpoint data associated with each endpoint of the video conference.

4. The method of claim 2 , further comprising ranking the endpoints in the video conference based on their view rank values.

5. The method of claim 2 , wherein each view rank value indicates a likelihood that the user associated with the respective endpoint is speaking.

6. The method of claim 2 , wherein each view rank value is based at least in part on a duration of speaking.

7. The method of claim 2 , wherein each view rank value is based at least in part on a type of audio detected.

8. The method of claim 2 , wherein each view rank value is based at least in part on a number of people who are in a room associated with the respective endpoint.

9. The method of claim 2 , wherein each view rank value is based at least in part on a type of endpoint.

10. The method of claim 2 , wherein each view rank value is based at least in part on a history of past video conferences.

11. The method of claim 2 , wherein each view rank value is based at least in part on whether at least one predetermined video function has been turned on.

12. A system comprising:

one or more processors; and

logic encoded in one or more tangible media for execution by the one or more processors and when executed operable to perform operations comprising:

providing a user interface of a video conference between at least a first user and a second user, wherein the first user is associated with a first endpoint and the second user is associated with a second endpoint;

determining view rank values for each of the first endpoint and the second endpoint; and

causing the user interface to display a first user video stream in a current presenter position and to display a second user video stream in a secondary presenter position based on the view rank values.

13. The system of claim 12 , wherein the logic when executed is further operable to perform operations comprising collecting endpoint data associated with each endpoint of the video conference.

14. The system of claim 12 , wherein the logic when executed is further operable to perform operations comprising ranking the endpoints in the video conference based on their view rank values.

15. The system of claim 12 , wherein each view rank value indicates a likelihood that the user associated with the respective endpoint is speaking.

16. The system of claim 12 , wherein each view rank value is based at least in part on a duration of speaking.

17. The system of claim 12 , wherein each view rank value is based at least in part on a type of audio detected.

18. The system of claim 12 , wherein each view rank value is based at least in part on a number of people who are in a room associated with the respective endpoint.

19. The system of claim 12 , wherein each view rank value is based at least in part on a type of endpoint.

20. The system of claim 12 , wherein each view rank value is based at least in part on a history of past video conferences.
