What is Video Conferencing?
Using ISDN technology or IP networks your image is digitally reproduced: it works like 2 way TV with real time audio and vision. Sometimes a video conference connection is also known as a ‘video link’ or ‘video meeting’. The main video conference equipment manufactures are Polycom, Tandberg, Sony, Aethra. These manufacturers are all working to the same protocols so the systems are able to link across brand. It is possible to link more than 2 sites together, this is known as a multipoint conference. Some video conference systems are able to link up to 4 sites together, but it is more usual to use a bridging service to connect the locations as bridges are able to connect to an unlimited number of video conferencing sites. Telepresence is a form of video conferencing which uses large screen, high definition technology to simulate being in the same room. Currently some telepresence systems are using proprietary technology and are not able to link with other video conference systems. With m
