US 2010/0302446 A1 · Video Superposition for Continuous Presence

Abstract

Techniques are described herein for combining video frames of two or more real-time video streams into combined video frames of a combined real-time video stream for continuous presence. Video frames of at least two real-time video streams are combined into combined video frames of a combined video stream. The combined video stream is supplied to a video display for displaying the combined video stream. Each video stream includes video frames with subject and background images. The subject images of corresponding video frames of the first and second video streams are combined into a combined video frame of a combined video stream such that the subject image of the first video stream is positioned in an anterior portion of the combined frame and the subject image of the second video stream is positioned in a posterior portion of the combined frame.

Dependent claims

A method comprising:

receiving at least first and second real-time video streams, each of the first and second real-time video streams comprising video frames containing a picture comprising a subject image and a background image;
combining the subject images of corresponding video frames of the first and second video streams into a combined frame of a combined video stream such that the subject image of the first video stream is positioned in an anterior portion of the combined frame and the subject image of the second video stream is positioned in a posterior portion of the combined frame;
and
supplying the combined video stream to a video display for displaying the combined video stream.

An apparatus comprising:

a first memory configured to store data for at least first and second real-time video streams, each of the first and second real-time video streams comprising video frames containing a picture comprising a subject image and a background image;
and
at least one data processor configured to combine the subject images of corresponding video frames of the first and second video streams into a combined frame of a first combined video stream such that the subject image of the first video stream is positioned in an anterior portion of the combined frame and the subject image of the second video stream is positioned in a posterior portion of the combined frame.

Logic encoded in one or more tangible media for execution and when executed operable to:

receive at least first and second real-time video streams, each of the first and second real-time video streams comprising video frames containing a picture comprising a subject image and a background image;
combine the subject images of corresponding video frames of the first and second video streams into a combined frame of a combined video stream such that the subject image of the first video stream is positioned in an anterior portion of the combined frame and the subject image of the second video stream is positioned in a posterior portion of the combined frame;
and
supply the combined video stream to a video display for displaying the combined video stream.
