Hard facts and harder questions about cable television and satellite interconnection, expanded from a symposium leader's remarks at the October 1972 SMPTE Technical Conference.Under the severe FCC restrictions on importing distant television broadcast signals, how can urban cable systems attract subscribers?Neither advertiser-supported nor noncommercial locally originated programming seems able to......

Contains a presentation given at the First International Cable Television Market held in Cannes, France.North American cable television systems are a good approximation of what is currently feasible; emphasis has focused on 12-channel, single coaxial cable systems.The only means now available for providing more than 12-channel viewing is a converter, which is often plagued by poor quality receptio......

Evaluates past CATV experience with local programming in Canada; in the somewhat isolated tract of Dale City, Virginia; and in Lakewood, Ohio, a suburb of Cleveland.The study concludes that (1) local programming can cost little to produce, (2) community-oriented programming can at times have high audience appeal, (3) local volunteer groups can produce only a few hours of programming per week to at......

A review of the field of power amplification at communication satellite frequencies.The relative ability of semiconductor devices and vacuum tube amplifiers to generate signal power efficiently at frequencies of 1 to 10 kMc and power levels of 0.1 to 100 watts is the primary concern of this paper.......

Rain influences the performance of a communication satellite link not only by attenuating the signal, but also by adding thermal noise to the other sources of sky noise.This paper (1) combines all sources of noise, including rain, as a function of frequency and elevation angle; and (2) presents estimates of time distributions of degradation of the down link due to rain for various system noise tem......

An argument for the use of the millimeter wave band for military earth-satellite communication systems.Important advantages accruing from this use are larger bandwidths and narrower antenna beamwidths, which would reduce interference and ameliorate the frequency management problem while also improving covertness and resistance to jamming.However, millimeter waves are particularly susceptible to at......

Develops a model for estimating in a new way the statistical distributions of signal attenuation, sky noise temperature, and total atmospheric-induced degradation in millimeter-wave link performance resulting from the presence of humidity, clouds, and rain in the atmosphere.The statistical distribution of system outages is then found for certain hypothetical commuications links using six frequenci......

Background material to place in proper context the effect of the use of millimeter-wave earth-to-satellite links on military communications. The complete writer-to-reader message path is described, including administrative delays (approval, awaiting pick-up, local mail delivery), communications processing, and transmission time. Analysis of statistics on speed of service for AUTODIN, the principal......

In this analysis of the factors influencing satellite spacing and frequency sharing, system parameter constraints are derived that could improve the compatibility of satellite and microwave relay systems sharing a common spectrum.Three types of stations are considered in analyzing spectrum sharing:terrestrial microwave repeaters and terminals, satellite repeaters, and earth-station terminals.There......

A compilation of ten papers on the development of broadband cable communications in the Dayton area, concerned primarily with the economics, technology, franchising, and ownership of cable systems, as well as the range of community services they might provide. Ten-year financial projections show that an interconnected network of six cable systems covering 13 incorporated cities in the Dayton, Ohio......
