VTC Distributed Learning Networks , Inc . The first thing to understand about videoconferencing is that it is different that satellite teleconferencing.
People often confuse the terminology and sometimes the technologies.
Another significant difference is in scale of sites involved. ITV teleconferences typically involve at least dozens, if not hundreds, sometimes even a thousand or more sites all connected at one time. Ford Motor Company, the USAF, and other large organizations routinely use 1V-2V satellite teleconferencing to deliver thousands of hours of sometimes highly technical, live, interactive training to sites that are geographically dispersed widely across the country. Very, very few organizations use videoconferencing routinely to do large scale instructional training. It simply is not economically cost effective.
