Satellite TV offers a distinct technological advantage over cable TV
systems: cable operations are essentially satellite operations in that cable
networks receive their programming via satellite but then re-transmit the
signals through the cable companies' trunk lines, which degrade the audio
and video signals to a greater or lesser degree on the way to the customer’s
home. Satellite TV, on the other hand, eliminates the intervening wiring and
provides a direct link from the satellite to the customer’s antenna in a
100% digital video and audio feed.
