How Direct TV Delivers Television To Your Home

If you're considering signing up for satellite TV service from Directv, you may be wondering how it works. While satellite TV is closely related to rocket science, it's not as complex as you might think.

All of Direct TV's programming starts out at one of two transmission centers - one in Castle Rock, Colorado and the other in Los Angeles, California- and is transmitted up to satellites in orbit around the Earth. The satellites then relay these signals down to the Earth's surface where they're picked up by individual satellite dishes that are installed at the homes of Directv customers. Once an individual satellite dish receives the signal, it sends the signal to the receiver. The receiver then selects the channel that the viewer wants, decompresses it, decodes it, and then displays it on the Television screen.

Naturally, the satellite TV transmission process used by Directv is a little bit more complex than that, but those intricacies just make it more interesting. For example, one of the reasons why Direct TV has two separate transmission centers in two different parts of the country is so that it can provide a backup feed to the satellites. With two transmission centers delivering the same signal simultaneously, viewers will experience little to no interruption even if one transmission center experiences power loss or some other disaster.

Another interesting fact is that the satellites used by Directv orbit 22,300 miles above the Earth's equator. At that altitude, the satellites are in what's called a geosynchronous orbit, which means that they stay in the same point in the sky as the Earth rotates. This eliminates the need to constantly aim the satellite dishes, have them track the satellites, and the resulting delays associated with waiting for the satellite dish to acquire a signal. It also means that the dishes themselves are nearly maintenance free!

Satellite technology also gives Direct TV an enormous advantage over cable TV in the form of capacity to transmit video. Video is incredibly data intensive, but satellite signals can carry more data at a time than cables can. The fact that Direct TV compresses its digital signal means that it can transmit even more channels over that impressive bandwidth.

Satellite television technology as used by Directv offers tremendous selection and flexibility for viewers. It makes sense to go with the company that offers plenty of great entertainment and equipment at very low cost - go with Directv Satellite TV. There has never been a better time to switch. Start now.
