Ever wonder how your satellite system works? There’s actually quite a bit of science going on behind scenes, with several components working together to bring you that digital-quality signal. Here’s a quick look at pieces that form your satellite puzzle.
Your channel selection begins with programming sources themselves. Companies like Showtime, HBO and Starz! all create their respective programming. Channel providers then purchase rights to this programming so that they can broadcast shows via satellite. Once a provider has their programming in place, they turn their attention to broadcast center to compress and convert programming for satellite broadcast.
Your programming original arrives as a digital stream of video, which is then compressed and converted through an encoder, typically using MPEG 2 format. This format reduces overall size of video, making it possible for a satellite to broadcast hundreds of channels at same time.
Once encoded, video is then encrypted so that broadcast can only be viewed by paying subscribers. This encryption “scrambles” signal so that those without proper receiver pick up distorted and unintelligible video. After video has been encrypted, it is sent to provider’s satellite, strategically positioned in sky.

In order to enjoy maximum results from your satellite dish, you need to be sure it’s receiving best possible signal. Where you point your satellite then, becomes an all-important step in getting great reception. But how does one point a satellite dish?
In truth, pointing your satellite dish isn’t as hard as you might think, but you will need to know a few things:
Azimuth which refers to horizontal measurement of a direction from North to East. In terms of your satellite dish, it tells you how far left or right your satellite should go.
Your altitude or elevation, gives your satellite dish its heading, telling it how far above horizon it needs to go.
And finally, polarization. Also known as “skew”, Polarization refers to adjustment needed for curvature of Earth. This rotational adjustment compensates for Earth’s curvature between dish and beam of satellite.
