Abstract: A system and method for an interactive, Internet-based videoconferencing multicast operation which utilizes a video production studio with a live instructor giving lectures in real-time to multiple participating students. The videoconference multicasting permits the students to interact with the instructor and other installations during the course of the lecture. In the case of software training, the system and method also utilize Internet-based application sharing and collaboration to permit the students at remote locations to drive a studio-based computer with the software for which the training is being given. The software screen is then used as a background with the instructor being able to literally point to areas of the screen which are being discussed. The instructor has a set of monitors in the studio which allow him/her to see the students on-location.
