Video teleconference
In telecommunication, the term video teleconference has the following meanings:
- A teleconference that includes video communications.
- Pertaining to a two-way electronic communications system that permits two or more persons in different locations to engage in the equivalent of face-to-face audio and video communications. Note : Video teleconferences may be conducted as if all of the participants are in the same room.
Video conferencing has in the past been relatively expensive, but prices are now coming down considerably, as it is possible for anyone with a fast enough internet connection to operate a video conference. Sometimes the conferencing takes place over a private network or VPN, which guarantees better performance, but there will be a trend towards running video conferences over the public internet as technology improves.
Video conferencing can be used for
- conducting interviews
- holding meetings
- setting up meetings
- giving lectures
and has the advantage that it can reduce the need for travel.
Because participants in a video conference may be working in different time zones, care must be taken with the organisation.
Video conferencing can also be used within organisations to provide immediate telepresence, using internal LANs as the communications infrastructure.
Examples include:
basically, using a network, a camera and a headset with videoconferencing people can interact as if they were talking face to face in a room. there are two types of video conferencing. one is called point to point conferencing which basically is a communication link between any two locations. another is multipoint conferencing which is a link between a variety of locations (more than two). multi point conferences can further be classified as two types, LAN and MCU (multi control unit). lan provides links between different locations, groups etc. In a Multi Control Unit environment, audio and video signals are automatically switched during conferencing (perhaps to attend to bandwidth issues).
