Videoconferencing (VC) is the conduct of a videoconference by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions. With powerful computing processors and video compression techniques, videoconferencing has made significant inroads in business, education, medicine and media. By reducing the need to travel, without flying, driving or catching trains, to bring people together the technology also contributes to reductions in carbon emissions, thereby helping to reduce global warming. Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over LAN or the Internet.
