Claim:
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, wherein the combining comprises: scaling the video frames of the first video stream and repositioning in a first direction the resulting pictures in the video frames of the first video stream to produce a first sequence of scaled video frames; removing the background image in the first sequence of scaled video frames to produce first background separated video frames to be displayed in the anterior portion of the combined frames of the combined video stream; and superimposing the first background separated video frames onto corresponding ones of the video frames of the second video stream to produce combined video frames of the combined video stream; and supplying the combined video stream to a video display for displaying the combined video stream.
