=What is IP Videoconferencing? Where was it invented? Is it a threat?= IP Videoconferencing is transmitting video and audio across the Internet to a specified IP address. Early versions of videoconferencing were unstable, expensive and not practical to implement in the K-12 environment. Today's videoconferencing is more successful due to the H.323 standard and better network bandwidth. There are three types of videoconferencing systems, room based system, mobile systems, and desktop systems.
