7.2.5 Video Conferencing

Conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data . For example, a point-to-point (two-person) video conferencing system works much like a video telephone. Each participant has a video camera, microphone, and speakers mounted on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the other's speakers and whatever images appear in front of the video camera appear in a window on the other participant's monitor .

Multipoint videoconferencing allows three or more participants to sit in a virtual conference room and communicate as if they were sitting right next to each other. Nowadays videoconferencing will be one of the fastest-growing segments of the computer industry for sharing information over computer networks throughout the world.
