Direct/community broadcast projects using space satellites

Abstract

A review is presented of direct/community broadcast projects which are currently in preparation in India, Canada, and Japan. It is shown that the satellite broadcast experiments involved are conducted for practical domestic reasons. The broadcast activities in all three projects will not reach other countries' TV receivers unless those countries take deliberate steps to enable themselves to receive such broadcasts. It is pointed out that for technological reasons problems of intrusion and interference connected with the use of satellites in broadcast operations may be much easier to handle than similar problems related to conventional radio broadcasting.
