Abstract

Methods, systems, and apparatus, including medium-encoded computer program products, for managing video bandwidth over a network connecting one or more cameras and one or more client video display stations. In one aspect, a system includes a data communication network, cameras coupled with the network, arranged in different locations, and operable to provide video imagery of the different locations via the network, one or more video fusion clients operable to display the video imagery of the different locations received via the network, one or more camera manager components operable to manage transmission of the video imagery from the cameras over the network based on client-side information, and one or more client manager components operable to define the client-side information based on display parameters of the one or more video fusion clients.

Claims

1. A system comprising:

a data communication network;

cameras coupled with the network, arranged in different locations, and operable to provide video imagery of the different locations via the network;

one or more video fusion clients operable to display the video imagery of the different locations received via the network;

one or more camera manager components operable to manage transmission of the video imagery from the cameras over the network based on client-side information; and

one or more client manager components operable to define the client-side information based on display parameters of the one or more video fusion clients.

2. The system of claim 1, the one or more camera manager components operable to manage transmission of the video imagery by excluding transmission of imagery from one or more of the cameras and by adjusting video stream parameters.

3. The system of claim 2, wherein the video stream parameters comprise frame rate, image resolution, compression quality, utilized bandwidth, and camera settings.

4. The system of claim 2, wherein the video stream parameters control output from a motion sensor and output from an alarm condition detector.

5. The system of claim 1, the one or more client manager components operable to define the client-side information based on display parameters comprising available screen area and current client activity.

6. The system of claim 1, the one or more client manager components operable to define the client-side information based on display parameters comprising number of available screen pixels and on-screen visibility of projected video.

7. The system of claim 1, wherein the data communication network comprises an inter-network.

8. The system of claim 7, further comprising proxy clients and proxy servers operable to manage bandwidth over a link between two networks in the inter-network.

9. The system of claim 1, wherein the one or more camera manager components comprise multiple camera manager components.

10. The system of claim 9, wherein each camera manager component is integrated with a respective camera.

11. The system of claim 9, wherein the multiple camera manager components are dynamically assigned to video streams from the cameras, including allowing assignment of multiple camera manager components to a single camera stream to manage peak loads.

12. The system of claim 1, wherein the one or more video fusion clients comprise multiple video fusion clients, and the one or more client manager components comprise multiple client manager components, each being integrated with a respective video fusion client.

13. An apparatus comprising:

a memory;

a network interface; and

a processor coupled with the memory and the network interface and programmed to perform operations comprising;

receiving client-side information for one or more video fusion clients, receiving video imagery from one or more cameras, and managing transmission of the video imagery over a data communication network to the one or more video fusion clients based on the client-side information.

14. The apparatus of claim 13, wherein managing transmission comprises adjusting video stream parameters.

15. The apparatus of claim 14, wherein the video stream parameters comprise frame rate, image resolution, compression quality, maximum bandwidth, and camera settings.

16. The apparatus of claim 14, wherein the video stream parameters control output from a motion sensor and output from an alarm condition detector.

17. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

identifying display parameters of one or more video fusion clients operable to display video imagery of different locations received via a data communication network;

generating client-side display information based on the display parameters; and

sending the client-side display information to one or more camera manager components operable to manage transmission of the video imagery over the network based on the client-side display information.

18. The computer program product of claim 17, wherein generating the client-side display information comprises generating the client-side display information based on available screen area and current client activity.

19. The computer program product of claim 17, wherein generating the client-side display information comprises generating the client-side display information based on number of available screen pixels and on-screen visibility of projected video.

20. A method comprising:

identifying display parameters of one or more video fusion clients operable to display video imagery of different locations received via a data communication network;

generating client-side display information based on the display parameters; and

sending the client-side display information to one or more camera manager components operable to manage transmission of the video imagery over the network based on the client-side display information.

21. The method of claim 20, wherein generating the client-side display information comprises generating the client-side display information based on available screen area and current client activity.

22. The method of claim 20, wherein generating the client-side display information comprises generating the client-side display information based on number of available screen pixels and on-screen visibility of projected video.

23. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

receiving client-side information for one or more video fusion clients;

receiving video imagery from one or more cameras; and

managing transmission of the video imagery over a data communication network to the one or more video fusion clients based on the client-side information.

24. The computer program product of claim 23, wherein managing transmission comprises adjusting video stream parameters.

25. The computer program product of claim 24, wherein the video stream parameters comprise frame rate, image resolution, compression quality, maximum bandwidth, and camera settings.

26. The computer program product of claim 24, wherein the video stream parameters control output from a motion sensor and output from an alarm condition detector.

27. A method comprising:

receiving client-side information for one or more video fusion clients;

receiving video imagery from one or more cameras; and

managing transmission of the video imagery over a data communication network to the one or more video fusion clients based on the client-side information.

28. The method of claim 27, wherein managing transmission comprises adjusting video stream parameters.

29. The method of claim 28, wherein the video stream parameters comprise frame rate, image resolution, compression quality, maximum bandwidth, and camera settings.

30. The method of claim 28, wherein the video stream parameters control output from a motion sensor and output from an alarm condition detector.
