Some Technical, Economic and Applications Considerations of Interactive Television.
Zraket, Charles A.
During the present decade cable television (CATV) systems will be franchised in most metropolitan areas of the nation. Previously, CATV has mainly transmitted over-the-air broadcast signals to small communities, but in the urban setting the capabilities of wideband cable (e.g., 30 channels per cable) can be expanded and applied to new communication needs. First, however, CATV must outgrow its identity as a retransmitter and become the medium for delivering a wide range of broadband communications services. Linked with computers, interactive cable systems can serve social, cultural, civic, education, governmental, business and commercial interests. The utility and importance of interactive CATV systems stem from the following characteristics: 1) they are individualized and respond instantly, privately, and economically to the user's needs; 2) they are computerized, offering search and calculation capabilities otherwise not available; 3) they provide unlimited points of entry and delivery of information, in addition to controlled storage, access, and retrieval; and 4) they are multimedia, encompassing video, audio, graphics, pictures, and alphanumeric text, and offer the potential of a common carrier between people.
