CATV : an expanding network for tomorrow / by Rene Guindon, Stu MacPherson, Joao DaSilva. : Co22-695/1973E-PDF

"The rapid development and growth of CATV systems in Canada presents a unique communications problem; The CATV system, as a localized distribution network, has the potential for providing a broad range of community, regional and even national communications services. In this era of rapid technological change, it is insufficient to assume that this potential will remain untapped, and that this facility will remain as a predominantly entertainment medium. In the absence of severe regulatory restrictions, the present 12 channel TV network is certain to give way to 20, 30 and more channels of visual material. Limited 2-way capability already exists facilitating the introduction of such services as pay-TV and information retrieval. Clearly, such innovations represent, at least in a localized or regional sense, a possible next-step in the evolution of local communications networks"--page 1.
