Abstract

Systems and methods for providing camera configuration for points in a multi-point videoconference system are provided. First configuration information is determined for a first point of a multi-point videoconferencing system. Second configuration information is determined for a second point of the multi-point videoconferencing system. One or more first cameras at the first point or one or more second cameras at the second point of the multi-point videoconferencing system are reconfigured based on the first configuration information or the second configuration information.

7. The method of claim 4, wherein generating a video stream that captures said camera viewpoint comprises synthesizing said viewpoint by processing outputs of a plurality of nearby cameras that capture overlapping views of a desired target.

8. The method of claim 1, wherein selecting a camera configuration based on the first participant configuration and the second participant configuration comprises detecting an opportunity for reconfiguration at one or both of the first endpoint or the second endpoint of the videoconferencing system and prompting a user for initiation of the reconfiguration at one or both of the first endpoint or the second endpoint of the videoconferencing system.

9. The method of claim 1, wherein selecting a camera configuration based on the first participant configuration and the second participant configuration comprises detecting an opportunity for reconfiguration at one or both of the first endpoint or the second endpoint of the videoconferencing system and automatically initiating reconfiguration at one or both of the first endpoint or the second endpoint of the videoconferencing system.

10. The method of claim 1, wherein selecting a camera configuration based on the first participant configuration and the second participant configuration comprises controlling video streams to and from at least one of the first endpoint and the second endpoint.

11. The method of claim 1, further comprising:

determining third participant configuration for a third endpoint of a videoconferencing system;

selecting a camera configuration for the first endpoint, the second endpoint, or the third endpoint, based on the first participant configuration, the second participant configuration, or the third participant configuration.
