DistanceEducation Columnist Note: Most of the articles in this column that have considered internet-based distance learning have looked at institutionsthat have developed internet based systems from their paper based systems. In this article, we look at how a closed circuit television based distance learning institution has adapted to develop a webcasting delivery system. Gordon Davies Computing Department Faculty of Mathematics and Computing The Open University Milton Keynes MK7 6AA UK USC's Distance Education Network (DEN) Ellis Horowitz Department of Computer Science University of Southern California Los Angeles, California 90089 USA or more than 25 years the School of Engineering has been delivering Masters level Engineering courses via closed circuit television. Established in 1972, the Interactive, Instructional TV Network, (IITV) offered a one-way video, two-way audio broadcasting system based upon microwave technology. Two transmitters strategically located on Mt. Wilson and Modjeska Peak, provide wireless coverage to most of the Los Angeles basin. Initially more than twenty Southern California companies subscribed. As our Aerospace constituency moved out of Los Angeles, we moved with them. In the 1980s we leased T1 lines connecting USC with Raytheon in Tucson and NASA/Ames (Silicon Valley) permitting us to send our courses beyond southern California.
