Direct-to-Home (DTH) satellite television is becoming a buzzword in the satellite broadcast industry due to the fact that DTH offers immense opportunities to both broadcasters and viewers. Thanks to the rapid development of digital technology, DTH broadcast operators worldwide have been able to introduce a large number of new interactive applications in the television market besides a large number of entertainment programmes over a single delivery platform. In addition, since digital technology permits a highly efficient exploitation of the frequency spectrum, the number of TV channels that can be broadcast using digital technology is significantly higher than with analogue technology. The increased number of television channels allows the operator to satisfy the demand of a number of niche markets with dedicated transmissions.
