Choosing Satellite TV Offers

When investigating satellite TV you need the right equipment to receive the signal. Even if you switch satellite services, you need new equipment. This is because each satellite company has a different signal and needs the right dish to recognize its signal.

A small satellite dish can be installed to pick up the signal. The signal is sent to the receiver by a coaxial cable. The signal is decoded and sent by coaxial cable to the TV.

The video signal starts out from a broadcast that is encrypted and sent to an orbiting satellite via a MPEG-4 compressed signal. The dish on your roof captures that signal and sends it to your receiver along a coaxial cable. The receiver than unscrambles the coded signal with the proper algorithm so that only those with proper access get to view it.

The most common type of satellite orbit is the geostationary orbit. Because of the velocity of the satellite and the perfect balance between the gravitation force due to the earth's pull, the satellite maintains a stationary orbit.

A new oval, slightly larger super dish is available for even more enhanced reception and it is called fittingly, SuperDish. It allows you to receive signals from different satellite locations so you get even more programming.

HDTV stands for high definition television and has twice the amount of pixels than the old analog TV signal. The signal is usually 1280x720 pixels. The two types of HD broadcast are: 720p - 1280x720 pixels progressive, 1080i - 1920x1080 pixels interlaced. The difference is that 1080i gives clearer slow motion imagery while the 720p gives better imagery for fast action such as basketball, NASCAR and such.

There are a lot of options when it comes to digital television reception. Cable companies have been known to raise rates while the satellite companies generally don't raise rates. Also, satellite allows for more diversified programming and channel selection.

Broadcast companies have different channels and different cost structures. There are the cable companies and there are two main satellite TV companies, Dish Network and DirecTV.
