The Evolution of Video Technologies for Distance Learning

摘要

This paper describes distance learning technologies utilized by the Stanford Instructional Television Network (SITN), the largest single university provider of televised graduate-level engineering and computer science courses in the world. Using a variety of delivery methods, SITN provides engineers, scientists, and technical managers throughout the U.S. and worldwide a means to extend their education without leaving their workplace by delivering to them graduate engineering courses, degree and certificate programs, short courses, and research seminars. Programming originates from ten specially designed studio classrooms each equipped as a complete TV studio utilizing robotically controlled TV cameras, special-effects generators, student microphones, “return-video” monitors, and return-audio circuits from the distant sites.
