First Claim
1. An interactive video conferencing system for use by at least a first conferee and a second conferee in a local module and a third conferee in a remote module, including:
- a first video camera in the local module and aimed at the first conferee, for generating a first video signal representing an image of the first conferee;
a second video camera in the local module and aimed at the second for generating a second video signal representing an image of the second conferee;
a video monitor having six discrete screen display areas in the remote module;
a composite video signal generation unit connected to the first video camera, the second video camera, and the monitor for receiving the first and the second video signals, generating a composite video signal from the first and the second video signals, and sending the composite video signal to the monitor for display, with the first video signal displayed on the monitor as a full video image in a large picture area, and the second video signal displayed on the monitor as a full video image in a small picture area.

Abstract
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.

4. An interactive video conferencing system for use by a set of conferees, including:
-
a video camera for each of the conferees, wherein each said camera generates a video signal representing a full video image; a video monitor for each of the conferees, wherein each said monitor has a large picture area and at least one small picture area; a composite video signal generation unit connected to the video cameras and to the video monitors for receiving the video signals, generating a composite video signal from the video signals, and sending the composite video signal to the monitors for display, with the video signals displayed on each monitor as a full video image in the large picture area, and each of the other video signals displayed on each monitor as a full video image in the large picture area, and each of the other video signals displayed on each monitor as a full video image in a distinct one of the small picture areas; a microphone for each of the conferees, wherein each said microphone generates a microphone signal; video signal selection means for receiving the microphone signals, identifying an active one of the microphone signals, and sending a control signal to the composite video signal generation unit, wherein the control signal identifies said principal one of the video signals, and said principal one of the video signals corresponds to the active microphone signal. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
