Here are some details on the pieces that make all of this possible.
Satellite Signal
Broadcasters produce content and then set up agreements with providers to hold their programs. When the broadcasters have produced the content it's sent to the satellite provider that is then encrypted right into a gifs and transferred to the uplink station for transmission located somewhere on the earth. In the United States, most of the satellites are operated in the southern hemisphere.

The Uplink Station
In means of communication this term may be used to describe the transmission of radio signals from earth to the high-powered satellite in outer space. Stations are set up with small to extremely large dishes ranging from a few feet up to 40 feet across. Larger satellite dishes often make the ability to send more information quicker and are known to be much more reliable than smaller dishes. Each station transmits data to some specific satellite in the sky within a specific frequency range.
High-powered satellite
The uplink station encrypts the data then sends it up towards the high-powered satellite in space. The data travels approximately 22000 miles into space. The satellite rotates inside the geosynchronous orbit at the same rate because the earth. If the satellite didn't rotate in the same speed as the earth this technology wouldn't be possible.
Small Dish Antenna and Satellite Receiver
Today's satellite dishes are very economical typically ranging from 1 to 3 feet (1 meter). Remember, you could obtain a larger dish which will improve your signal and leave you less susceptible to outages. The satellite dish is set up outside a cable is ran in the satellite dish to your home and into the satellite receiver. The satellite cable is not linked to a network and frequently you do not share the machine with others so there is little room for error if there is an issue.
To conclude, the end user will get channels based upon their subscription to the service. Channel availability is based upon the satellite provider. Satellite television can be set up regardless of location along as there is a clear look at the southern sky.
