    This paper describes a questionnaire-type survey conducted in 1970 of the nature, size, and composition of the likely market for broad-band two-way services to the home. Market demand characteristics are considered in detail for thirty likely services. The composite magnitude of the industry is estimated as essentially starting in 1980 and building up to a dollar volume of $20 billion per year. View full abstract»

    Four years have passed since the survey was conducted leading to the preceding paper [1]. Little work has been done, and even less progress has been made toward the goal of the new system developments. The present paper explores impediments that the writer believes are presently blocking the development of the potential broad-band cable interactive services industry. The key issues present are ide... View full abstract»

    The broad-band communications industry is small and fractionated (about 3100 cable television systems serving 8.5 million subscribers in the U.S.), but has a high potential for growth by offering a wide variety of communications services. If this large number of systems is to collectively provide nationwide services, performance and interconnection standards will be essential. In this paper we not... View full abstract»

    Information systems will always remain a subset of interactive communications systems. These physical networks will reflect the relationships between people and information. The element of surprise will always remain, however. Suppose that the recent work at the Stanford Research Institute in communicating straight from the brain to computer augmentation is continued and is perfected. This will le... View full abstract»

    Urban development of cable, generally regarded as a prospective testbed of interactive cable services, has not started on the optimistic path many predicted when the current FCC cable regulations took effect in 1972. Cable growth, and industry emphasis, have been markedly within franchises rather than in new franchises recently. Economic rather than regulatory forces may have been largely responsi...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (800 KB)

    Cable television (CATV) is developing in Europe in response to three primary demands: the improvement of over-over-the-air reception of both television and FM radio channels, the provision of increased program diversity through the reception of additional foreign and domestic signals, and the reduction of numerous unsightly antennas. Technical advantages that cable provides are the primary reason ... View full abstract»

    Pilot two-way CATV systems have been mounted in the United States largely to assess the marketability of various interactive services (e.g., subscriber response) and to assess technical problems over operating CATV systems. Such tests were at their peak in the early 1970's. Twelve systems which have been publicly tested are considered briefly. Three of these, the Theta-Com subscriber response syst...

    The features and limitations of time- and frequencydivision miltiplexed (TDM and FDM) systems for providing interactive services on broad-band communication networks are considered. We find that TDM systems make efficient use of bandwidth for digital signal rates below 10 kbits/s while FDM systems are efficient for analog signals and digital signal rates above 1 kbit/s. Although TDM and FDM system... View full abstract»
