Video Teleconferencing

What is Video Teleconferencing (VTC)?

Video Teleconferencing is a communication technology that allows two or more users in different locations to communicate by creating a face-to-face meeting over long distances.VTC can transmits bi-directional audio, video and data streams. It’s in widely used now on cell phones.

Video teleconferencing allows live exchanges of information without the lost time and high cost of traveling to attend a face-to-face meeting in a different parts of the world or even down the block. Video teleconferencing offers many beneficial applications such as training and distance learning, data collaboration, telecommuting, large and small meetings, and informational broadcasts.

Video Teleconferencing may come in the form of a video communication session among three or more people or groups that are at separate locations. This form of conferencing started with a room that is equipped with groups of people, and with a wide-angle camera and large monitors or LCD, the same setup would be in effect at the other locations or with the end users.

The two basic types of VTC systems are the dedicated systems and the desktop systems. They generally consist of a microphone, speakers, and camera,

Common components in a standard VTC network are Call server, Video Endpoint, Multipoint Conference Unit, Gateways, and an Ethernet switch. A Call sever performs the registration and call control processing functions. Video Endpoints are devices from which users make and receive video calls. The endpoint processes the bi-directional audio, video, and data streams and interfaces to the users.

Point-to-Point is the most basic architecture for a VTC network. This configuration does not require a Call Server and does not allow conferencing of more than two endpoints, but it does allow for direct video and audio calls between endpoints within a cluster.
