1. Introduction

Satellite Television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block down converter. A satellite receiver then decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service.
