Digital satellietes transmit your tv stations to your dish network. When you have your dish or satellite tv set up to get digital stations, it transmits back from the satellite to your tv.

Satellite television service, just like cable, was unaffected by the digital television switch.

You can find a circuit diagram of most digital satellite receivers at many electronic stores. You can also get the diagram from the satellite receiver manufacturer.

Satellite broadcasters such as direct tv and dish network have all ways transmitted digital from day one.

Satellite TV Providers transmits the signals through their satellite dish converting it first from digital signals to analog signals. These signals which were converted will be transmitted to the satellite. The satellite will then transmit the analog signals per request of the satellite dish connected to the receiver of the subscriber. Once signals are received, it will be converted back to digital signals which can be read by the receiver and be displayed to the television.
