ABSTRACT
Figure 6.15-1 provides a simplified diagram of an alldigital multichannel direct-to-home satellite system, which comprises four main subsystems:
• Program contribution • DTH broadcasting facility and uplink • Broadcasting satellite(s) • Customer equipment
DTH program channels originate at a variety of remote locations and most are also available to other program distributors. These channels arrive at the DTH broadcasting or uplink facility via existing “backhaul” satellites or fiber-optic links. Some programming, such as theatrical films for pay-per-view, arrive at the facility as prerecorded digital tapes.
