subject: Satellite Hidef Tv Provider [print this page] As you are researching the pros and cons about satellite TV, you should know that you need the proper equipment. No matter if you switch from another TV satellite service, you need their dish since it is programmed to receive and recognize that particular 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.
If you're looking for the top of the line in reception, there is the SuperDish. It is oval in shape and slightly larger than the normal small dish you see on top of roofs. It's enhanced signal gathering capabilities allow signals from 3 different satellites which means you get more programming.
High definition transmission like arrives as either 1080i - 1920x1080 pixels interlaced or 720p - 1280x720 pixels progressive. The 1080i is a sharper image for slow action and not a lot of movement pictures. Whereas, 720p allows more distinction for fast action video such as sports or animals in flight.
Very often people get frustrated by cable companies continually raising their rates and they begin to look elsewhere. Satellite TV offers more programming for less costs and the reception equipment is generally free.
When you are looking for a competitive deal, there may only be one or two cable companies you can choose from in your area. But for satellite companies, there are only two.
