Direct TV Program Source

Content for Direct TV comes from 2 different types of sources: there are national providers such as HBO, ESPN and CNN and the local channels like NBC, CBS, ABC, PBS and Fox affiliates in particular areas.

Geo-synchronous Satellites

Geo-synchronous satellites remain in the same point in the sky and orbit at 22,000 miles or 35,700 km above the planet and travelling at a speed of 7,000 mph or 11,000 kph.
Direct TV Distribution Center

All the Direct TV programs and channels are mixed into a single signal that is beamed out to the satellites and then into your homes from the Direct TV Distribution Center.
Compression, Encoding & Encryption

Compression technology enables a satellite to carry over 200 TV channels instead of an uncompressed 30 channels.
Satellite Dish

The satellite dish is a directional antenna designed to focus on a specific point. The standard satellite dish antenna is a parabolic dish made out of or coated in radio reflective material, which forms a concave lens with a feed horn located at its focus.

Satellite Receiver

The Satelitte Receiver decodes the signal so that your TV can display the channel.
