Group videoconferencing enables groups of people in different geographical locations to meet face to face. Conferees can exchange information, documents, ideas, and data while employing a variety of visual aids. Visual aids can include interactive writing and drawing, prepared text and graphic materials, and prerecorded audio and video material. Improved technology, superior camera optics, and digital audio signals result in video pictures that are equal to commercial broadcast quality.
Users start videoconferences from an easy-to-use control console and conduct the conference as easily as they operate a telephone. No special technical expertise is required.
Group video systems are often integrated in a mobile roll-about console that can be wheeled easily into a conference room or executive office prior to a scheduled videoconference call. Alternatively, the components can be built into a videoconference room.
Older group videoconferencing systems use V.35 interfaces, requiring two ISDN terminal adapters or an inverse multiplexor (IMUX); these components are sometimes included with the systems. Newer group videoconferencing systems use ISDN/BRI interfaces and include data communications equipment.
