Abstract :
Over the past few years the New York State Education Department has conducted a number of experiments using TV (television) as a means of communication between teachers and pupils. The most recent endeavor in this series is a closed circuit educational TV system in Cortland County, N. Y. The primary objective is to determine the effectiveness of elementary and high school teaching via TV. The purpose of this paper is to describe a portion of the project involving the New York Telephone Company, namely, the transmission of video and audio signals from the point of origination to the schools where the information is presented to the pupils.
