Direct Broadcasting Satellites--Myth or Reality.
Twenty-three years after the launching of the first satellite, there is still no fully operational direct broadcasting satellite system. Since such systems were expected much earlier, many questions present themselves concerning (1) whether there is a perceived need for such a system, (2) whether the technology is available at cost effective levels, (3) whether that technology has been adequately tested, and (4) whether the system could create more problems than it would solve. An evaluation of the situation suggests that there is a need for direct broadcast satellites to serve large areas of low population density and that the technology is available at cost effective levels; experiments and studies in Canada have indicated that low power level satellites are especially cost effective. In addition, the technology is being tested and three satellite launches have been conducted: HERMES, providing service to Canada, the United States, and Australia; YURI, providing service to Japan; and ANIK-B, providing service to Canada. Other projects are currently under consideration in more than nine countries. Problems do arise from the system, since satellite coverage is very broad and the signal cannot be prevented from crossing national borders, thus causing conflicts between the provision of a totally free flow of information and the right of each nation to determine what shall be broadcast to its citizens.
