System and method for combining a plurality of video streams generated in a videoconference
First Claim
1. A method of forming a panoramic video image from video images received from two or more video cameras located at a single videoconferencing site, comprising:
- receiving two or more video streams generated by the two or more video cameras;
identifying an overlay area that appears in the video image data related to at least two of the video streams;
forming a stream of panoramic video image data representative of the two or more video streams by stitching the video image data of the two or more video stream in real time,wherein the panoramic video image data contains a single instance of the video data related to the identified overlay area.

Abstract
Disclosed herein is a method and apparatus for videoconferencing that allows video images from two or more cameras at the same site to be displayed as a single panoramic image. Accordingly, a conferencing endpoint having a single monitor can display the panoramic image of the two or more video images from an endpoint having multiple cameras, such as a telepresence endpoint. A sliding display area can be used to define manually a zoomed portion of the panoramic image to be displayed. Alternatively, the zoomed portion may be determined automatically. The zoomed portion may be changed during the course of the conference.

24. A method for displaying two or more video images received from a telepresence videoconferencing system as a panoramic video image on a single videoconferencing display unit, comprising:
-
receiving at least two compressed video streams from the telepresence videoconferencing endpoint; decoding the compressed video streams to yield video image data for each of the two or more video streams; identifying in real time an overlay area that appears in the video image data related to at least two of the decoded video streams; and stitching the video image data of the video streams of the two or more video streams in real time to form panoramic video image data representative of the two or more video streams, wherein the panoramic video image data contains a single instance of the video data related to the identified overlay area. - View Dependent Claims (25, 26, 27, 28)

29. A video conferencing unit for forming a panoramic video image from compressed video streams from two or more cameras at a single videoconferencing terminal, comprising:
a video control unit adapted to; decode the compressed video streams to yield video image data representative of video images for each of the video streams; identify an overlay area that appears in the video image data related to at least two of the video images; stitch the video image data of the video images to form panoramic video image data representative of the two or more video images wherein the panoramic video image data contains a single instance of the video data related to the identified overlay area, encode the panoramic image data; and send the encoded panoramic image data toward a videoconferencing terminal. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
