The distribution system for network television signals involves the tandem connection of many different transmission systems, all of which presently operate using analog techniques. During the 1980's, the common carriers will install many digital transmission systems so as to realize the maximum economic benefit from digital switching machines. As a consequence it is virtually certain that by 1990 some, if not most, of the distribution system for network television signals will involve the use of digital transmission techniques. - The present situation regarding digital transmission of television signals in North America is reviewed and some areas of concern are noted. There is an obvious need for close liaison between the broadcaster, the common carriers, the manufacturers and the regulatory authorities if the present quality of the distribution system is to be maintained.
