Abstract
Split-screen video displays are presented at a plurality of different sites for a video teleconference. Video cameras are focused respectively upon the conferees directly, and centrally. The displays at each site show the conferees at remote sites. The positioning of the conferees at different sites on a display is achieved electronically, as by delays of a half a line and/or delays of half a field, rather than by panning or tilting of a camera.
