摘要

The first practical video conferencing systems were introduced at the Fourth World Telecommunications Forum held in Geneva in 1983 [Eva95], but their use is still rare. By comparison, the personal computer, introduce about the same time, is now a commodity sold by the millions.That is surprising, considering the cost and time savings associated with teleconferencing and the economy of scale achievable by teleteaching.This paper presents the position that lack of quantity and quality in the transmission process are responsible for the low success.
