Satellite and Television System Components
There are five basic components in a satellite system called direct-to-home or direct-to-air. These:
Programming resources: The provider pays different companies for the right to broadcast their content via satellite, without creating the programming itself. In this way, the provider is a kind of intermediary between the client and the actual programming resources. (Cable TV companies work with this logic.)
The broadcast center is the center of the system. In the broadcast center, the TV provider receives signals from different programming sources and sends a broadcast signal to satellites in geosynchronous orbit.
Satellites receive signals from the broadcast station.
The dish receives the signal from the satellite and transmits it to the receiver in the individual's home.
The receiver processes this incoming signal and transmits it to a standard television.
