Abstract

A method and apparatus for displaying video is provided herein. During operation, video is displayed on one of many displays in a geographically correct fashion. For example, in an embodiment involving two displays (e.g., on a firefighter'"'"'s two wrists), each of which display a video feed, the video is displayed such that the video feed of the most appropriate scene (not necessarily the video feed of the closest camera) is shown on that display.

Claims

1. A method for a display device to display a field of view (FOV) captured by a camera, the method comprising the steps of:

receiving the FOV from the a camera;

determining a location of the FOV captured by the camera;

determining an orientation of the display device;

determining the position of the display device with respect to other display devices; and

determining whether or not to display the FOV received from the camera based on the location of the FOV, the orientation of the display device, and the position of the display device with respect to the other display devices.

2. The method of claim 1 wherein the step of receiving the FOV comprises the step of receiving the FOV as a video or a still image or a thermal image.

3. The method of claim 1 wherein the step of determining the location of the FOV captured by the camera comprises the step of receiving meta-data from the camera indicating the location of the FOV.

4. The method of claim 1 wherein the step of determining an orientation of the display device comprises the step of determining a compass heading of the display device.

5. The method of claim 1 wherein the step of determining the position of the display device with respect to other display devices comprises the step of determining if the display device lies to the right, to the left, above, or below the other display device.

6. The method of claim 1 further comprising the step of:

displaying the FOV on the display device when the FOV is located X of the display device and the display device is X-most display device, wherein X=north, south, east, or west, otherwise not displaying the FOV.

7. The method of claim 1 wherein the step of determining the location of the FOV comprises the step of determining location of the camera, a compass direction to which the camera is pointing, or geographic information about the camera, or a relative position with respect to a known landmark.

8. A method for a display device to display a FOV, the method comprising the steps of:

receiving multiple field of views (FOVs) from multiple cameras;

determining locations of the FOVs captured by the multiple cameras;

determining an orientation of the display device;

determining the position of the display device with respect to other display devices; and

determining what FOV to display based on the location of the FOV, the orientation of the display device, and the position of the display device with respect to the other display devices.

9. The method of claim 8 wherein the step of receiving the multiple FOVs comprises the step of receiving the multiple FOVs as video or images.

10. The method of claim 8 wherein the step of determining the location of the FOVs captured by the multiple cameras comprises the step of receiving meta-data from the multiple cameras indicating the location of the FOV.

11. The method of claim 8 wherein the step of determining an orientation of the display device comprises the step of determining a compass heading of the display device.

12. The method of claim 8 wherein the step of determining the position of the display device with respect to other display devices comprises the step of determining if the display device lies to the right, to the left, above, or below the other display device.

13. The method of claim 8 further comprising the step of:

displaying an FOV on the display device when the FOV is located X of the display device and the display device is X-most display device, wherein X=north, south, east, or west.

14. The method of claim 8 wherein the step of determining the locations of the FOVs comprises the step of, for each FOV, determining location of the camera, a compass direction to which the camera is pointing, or geographic information about the camera, or a relative position with respect to a known landmark.

15. An apparatus comprising:

a receiver receiving multiple field of views (FOVs) from multiple cameras;

context-aware circuitry determining an orientation of the display device; and

logic circuitry determining locations of the FOVs captured by the multiple cameras, determining the position of the display device with respect to other display devices, and determining what FOV to display based on the location of the FOV, the orientation of the display device, and the position of the display device with respect to the other display devices.

16. The apparatus of claim 15 wherein the multiple FOVs are received as video or images.

17. The apparatus of claim 15 the location of the FOVs captured by the multiple cameras are received as meta-data from the multiple cameras.

18. The apparatus of claim 15 wherein the orientation comprises a compass heading of the display device.

19. The apparatus of claim 15 the position of the display device with respect to other display devices comprises to the right, to the left, above, or below the other display device.

20. The apparatus of claim 15 further comprising:

a monitor displaying an FOV on the display device when the FOV is located X of the display device and the display device is X-most display device, wherein X=north, south, east, or west.
