Abstract: The motivation for contemporary efforts towards the development of improved television systems is presented. The impossibility of obtaining substantial improvements by straight-forward means, such as increasing the line and frame rates, without excessive bandwidth expansion, is discussed. The television process is described as a linear system whose task is the transmission of a “video function”, which is continuous in x, y, and t. The fidelity requirements for the transmission of the video function are related to the psychophysical properties of the human visual system, which are reviewed. Making use of the prospects of quite complicated signal processing through developments in semiconductor technology, a series of possibilities for improved systems is explored. Some of these proposed methods take advantage of the spatio-temporal characteristics of the video function which are inherent in its role as the conveyor of picture information to human viewers. Others deal with the special characteristics of TV cameras and displays as perceptual information processors and make use of signal processing to improve their performance.

bio
William F. Schreiber was born in New York City in 1925. He received the B.S. and M.S. degrees in Electrical Engineering from Columbia and the Ph.D. in Applied Physics in 1953 from Harvard University. Dr. Schreiber was a junior engineer at Sylvania from 1947–1949. From 1953 to 1959 he directed electronicsm research at Technicolor Corp. Since 1959 he has been with MIT, where he is Professor of Electrical Engineering. From 1964 to 1966 he was Visiting Professor of Electrical Engineering at the Indian Institute of Technology, Kunpur, India, and in 1980–1981 he was half-time Visiting Professor at the University of Quebec, Montreal, Canada. Since 1948 Dr. Schreiber's major professional interest has been in picture coding and transmission systems. He is associated with the Cognitive Information Processing Group of the Research Laboratory of Electronics at MIT where an active program in this field is under way. He has also served as consultant on image transmission systems to a number of industrial and government laboratories.
