Abstract

A computer implemented method includes extracting one or more portions from a first video stream of a first physical environment; transmitting captured video data via a first communication link to one or more electronic display devices disposed within a second physical environment, wherein the captured video data includes the one or more extracted portions and the captured video data includes a preview portion that includes a first portion of a frame of the first video stream; and transmitting a second video stream of a second field of view of the first physical environment to at least one of the one or more electronic display devices disposed within the second physical environment via a second communication link, wherein the second video stream is generated in response to a selection of the preview portion of the captured video data made by a user located in the second physical environment.

First claim

What is claimed is:

1. A video conferencing system comprising a controlling device and one or more cameras, wherein the one or more cameras are configured to view a first physical environment and the controlling device is configured to:
receive a first video stream of the first physical environment from one of the one or more cameras;
extract one or more portions from the first video stream;
transmit first captured video data via a first communication link to one or more electronic devices disposed within a second physical environment that is remote from the first physical environment, wherein the first captured video data includes or is derived from the one or more extracted portions and the first captured video data includes
a first preview portion that includes at least a first portion of a first frame of the first video stream, and
a second preview portion that includes at least a second portion of the first frame of the first video stream, wherein the first preview portion and the second preview portion are views of separate areas of the first physical environment; and

transmit a second video stream of the first physical environment to at least one of the one or more electronic devices disposed within the second physical environment via a second communication link, wherein
the second video stream is generated in response to a selection of the first preview portion of the first captured video data in the second physical environment.

2. The video conferencing system of claim 1 , wherein the first captured video data includes an overview preview portion that includes at least a third portion of the first frame of the first video stream, wherein the overview preview portion includes the first preview portion and the second preview portion.

3. The video conferencing system of claim 1 , wherein the first captured video data comprises one or more still images.

4. The video conferencing system of claim 1 , wherein
the first captured video data comprises video, and
a data transfer rate of the first captured video data to the second physical environment via the first communication link is 10% or less than a data transfer rate of the second video stream to the second physical environment.

5. The video conferencing system of claim 1 , wherein the first captured video data includes video thumbnails or picture thumbnails of two or more locations in the first physical environment.

6. The video conferencing system of claim 1 , wherein
the first video stream is generated by a first camera of the one or more cameras, the first camera having a first field of view of the first physical environment, and
the second video stream is generated by a second camera of the one or more cameras, the second camera having a second field of view of the first physical environment.

7. The video conferencing system of claim 6 , wherein the second video stream is generated by the second camera after one or more of panning, tilting, or adjusting a zoom of the second camera.

8. The video conferencing system of claim 1 , wherein
the first video stream is generated by a first camera of the one or more cameras, the first camera having a first field of view of the first physical environment, and
the second video stream is generated from a portion of the first video stream.

9. The video conferencing system of claim 8 , wherein
the second video stream and the first preview portion are of the same views of the first physical environment.

10. The video conferencing system of claim 1 , wherein
the one or more extracted portions includes a plurality of extracted portions, and
the controlling device is further configured to generate a preview portion for each user located within a first field of view of the first physical environment upon determining that two or more users are located within the first field of view of the first physical environment, wherein each generated preview portion displays a face of the user for which the preview portion was generated.

11. The video conferencing system of claim 10 , wherein the controlling device is further configured to generate a new preview portion upon determining that a new user has appeared within the first field of view of the first physical environment, wherein the new preview portion displays a face of the new user.

12. The video conferencing system of claim 1 , wherein the controlling device is further configured to alter at least a portion of the first captured video data or the second video stream based on an analysis of the first video stream, wherein the analysis of the first video stream comprises performing an image processing technique on the first portion of the first frame of the first video stream.

13. A video conferencing system, comprising a first controlling device, a first camera and a second camera, wherein the first controlling device is configured to:
receive a first video stream from a first camera, wherein the first camera has a first field of view of a first physical environment;
receive a second video stream from a second camera, wherein the second camera has a second field of view of the first physical environment;
extract one or more portions from the received first video stream;
transmit first captured video data via a first communication link to one or more electronic devices disposed within a second physical environment that is remote from the first physical environment, wherein the first captured video data includes or is derived from the one or more extracted portions and the first captured video data includes a first preview portion that includes at least a first portion of a frame of the first video stream;
transmit the second video stream to at least one of the one or more electronic devices disposed within the second physical environment via a second communication link;
receive a first command, wherein the first command is derived from a selection of the first preview portion of the first captured video data in the second physical environment;
alter the second video stream based on the received first command; and
transmit the altered second video stream to at least one of the one or more electronic devices disposed within the second physical environment via the second communication link.

14. The video conferencing system of claim 13 , wherein the first captured video data includes a second preview portion that includes at least a second portion of the frame of the first video stream, wherein the first preview portion and the second preview portion are views of different areas of the first physical environment.

15. The video conferencing system of claim 14 , wherein the first captured video data includes an overview preview portion that includes at least a third portion of the frame of the first video stream, wherein the overview preview portion includes the first preview portion and the second preview portion.

16. The video conferencing system of claim 13 , wherein the first captured video data includes one or more still images.

17. The video conferencing system of claim 13 , wherein
the first captured video data includes video, and
a data transfer rate of the first captured video data to the second physical environment via the first communication link is 10% or less than a data transfer rate of the second video stream to the second physical environment.

18. The video conferencing system of claim 13 , wherein the first captured video data includes video thumbnails or picture thumbnails of two or more locations in the first physical environment.
