Video conferencing is two way, real-time transmission of audio and video signals between specialized devices or computers at two or more locations via satellite (wireless) over a network such as a LAN or internet. Full motion (30 frames per second), full color videoconferencing requires a bandwidth of 6 megahertz (MHz) for analog signals and 1.54 megabits per second (Mbps) of digital signals. Videoconferencing protocols are governed by the ITU-TSS standard H.261 and its successors. Also called video teleconferencing.
