Abstract

A system and method for a virtual omni-directional camera array, comprising a video control system (VCS) coupled to two or more co-located portable or stationary information processing systems, each enabled with a video camera and microphone, to provide a composite video view to remote videoconference participants. Audio streams are captured and selectively mixed to produce a virtual array microphone as a clue to selectively switch or combine the video streams from individual cameras. The VCS selects and controls predetermined subsets of video and audio streams from the co-located video camera and microphone-enabled computers to create a composite video view, which is then conveyed to one or more similarly-enabled remote computers over a broadband network (e.g., the Internet). Manual overrides allow participants or a videoconference operator to select predetermined video streams as the primary video view of the videoconference.

Claims (30)

1. A system for displaying video on information handling systems, comprising:

a plurality of information handling systems;

a plurality of video cameras operably coupled to said plurality of information handling systems, wherein each of said plurality of video cameras comprises a local angle of view and each of said information handling systems is operable to generate a video stream comprising said local angle of view; and

a video control system operably coupled to said plurality of information handling systems;

wherein said video control system is operable to select predetermined subsets of said video streams and generate a composite video display therefrom; and

wherein the video image size of each of said predetermined video streams within said composite video display is respectively dependent upon said corresponding local angle of view.

2. The system of claim 1 , wherein said plurality of information handling system comprises a set of information handling systems that are physically co-located.

3. The system of claim 2 , wherein said plurality of information handling systems further comprises a set of information handling systems that are not physically co located.

4. The system of claim 3 , wherein said set of co-located information handling systems are operably coupled to said set of remotely located information handling systems by a broadband network.

5. The system of claim 4 , wherein said broadband network is implemented using a Realtime Communications Protocol (RTC).

6. The system of claim 5 , wherein said video control system is further operable to concatenate said predetermined video streams from said set of physically co-located information handling systems to generate a virtual panoramic view within said composite video image.

7. The system of claim 1 , wherein said set of physically co-located information handling systems further comprise audio input devices.

8. The system of claim 7 , wherein said video control system is further operable to receive audio signals from said audio input devices and to selectively mix said audio signals to create a virtual array microphone therefrom.

9. The system of claim 8 , wherein said video control system is further operable to process said audio signals to generate control signals to selectively switch or combine said predetermined subsets of video streams for said generation of said composite video display.

10. The system of claim 9 , wherein said video control system is further operable to process said audio signals to generate a control signal to select a video stream from an individual information handling system as a primary video image for display within said composite video display.

11. A method of displaying video on information handling systems, comprising:

using a plurality of information handling systems;

using a plurality of video cameras operable connected to said plurality of information handling systems, wherein each of said plurality of video cameras comprises a local angle of view and each of said information handling systems is operable to generate a video stream comprising said local angle of view; and

using a video control system operably coupled to said plurality of information handling systems;

wherein said video control system is operable to select predetermined subsets of said video streams and generate a composite video display therefrom; and

wherein the video image size of each of said predetermined video streams within said composite video display is respectively dependent upon said corresponding local angle of view.

12. The method of claim 11 , wherein said plurality of information handling system comprises a set of information handling systems that are physically co-located.

13. The method of claim 12 , wherein said plurality of information handling systems further comprises a set of information handling systems that are not physically co-located.

14. The method of claim 13 , wherein said set of co-located information handling systems are operably coupled to said set of remotely located information handling systems by a broadband network.

15. The method of claim 14 , wherein said broadband network is implemented using a Realtime Communications Protocol (RTC).

16. The method of claim 15 , wherein said video control system is further operable to concatenate said predetermined video streams from said set of physically co-located information handling systems to generate a virtual panoramic view within said composite video image.

17. The method of claim 1 , wherein said set of physically co-located information handling systems further comprise audio input devices.

18. The method of claim 17 , wherein said video control system is further operable to receive audio signals from said audio input devices and to selectively mix said audio signals to create a virtual array microphone therefrom.

19. The method of claim 18 , wherein said video control system is further operable to process said audio signals to generate control signals to selectively switch or combine said predetermined subsets of video streams for said generation of said composite video display.

20. The method of claim 19 , wherein said video control system is further operable to process said audio signals to generate a control signal to select a video stream from an individual information handling system as a primary video image for display within said composite video display.
