VIDEO CONFERENCING
What is VideoConfernencing
Videoconferencing uses telecommunications of audio and video to bring people at different sites together for a meeting.
This can be as simple as a conversation between two people in private offices (point-to-point) or involve several sites (multi-point) with more than one person in large rooms at different sites. Besides the audio and visual transmission of people, videoconferencing can be used to share documents, computer-displayed information, and whiteboards. Improvements are being made in collaborative tools that allow people at different sites to electronically manipulate a common document or computer application.
IEEE standards guide the development of videoconferencing. The H.320 standard describes how video conferencing operates over ISDN telephone circuits (The ISDN communications standard specifies how a single wire or optical fiber can carry voice, digital network services, and video).
Typically, an ISDN has more bandwidth than a regular analog telephone circuit.
H.323 describes how videoconferencing operates over the Internet (TCP/IP or just IP).
Multipoint Conferencing Units (MCUs) handle the traffic flow in multi-point videoconferences and typically include gateway capabilities to bridge H.320 and H.323 sites together in a conference.
The quality of a videoconference primarily depends on the characteristics of the connection between the conferencing sites. In the H.323 world, a high-quality conference (excellent audio and video) needs about 768Kbs (KiloBits/Second) of bandwidth.
