Abstract
The extensive coverage of the USA by cable television has posed a major hurdle for successful use of direct broadcast satellites. However, the potential for DBS service is improving because of breakthroughs in development of digital video compression and the availability of high-power satellites, combined with ample allocations of radio spectrum and orbital slots to DBS service. The success of DBS applications will depend critically on (a) the cost of small-antenna home receiving terminals, (b) operating expenses, and (c) demand for new services, such as HDTV, that could be provided by DBS systems more quickly and cheaply than through terrestrial transmission.
