A conferencing system for interactive video (and preferably also audio) communication, which includes a composite video signal generation means. The system preferably also includes a recording unit for producing a permanent, combined video and audio record of a conference (which may be a court proceeding such as a criminal arraignment). The system includes a monitor for each conferee, which displays a composite video signal including a principal video image in a large picture region of the monitor screen and secondary video images in small picture regions of the monitor screen. Preferably, all of the large and small picture regions have substantially the same aspect ratio, full secondary video images are displayed in the small and large picture regions, and the full video images displayed in the small picture regions do not obscure any portion of the full video image displayed in the large picture region. In an alternative embodiment, the small picture regions are displayed in a picture-in-picture window which obscures a portion of the principal image displayed in the large picture region.
