How Satellite TV Works
By Mitchell Medford
Digital high definition satellite television is increasing in popularity, with Dish
Network recently reporting crossing the 12 million subscriber threshold and
growing, and there are probably more uninformed as to actual workings of
satellite TV than informed. How does Dish Network make television
programming so realistic in image and sound?
Dish Network, owned and operated by EchoStar Communications, receives
digital satellite signals from their fleet of nine satellites. Plans are underway
at present for EchoStar to launch their tenth satellite this month - February -
increasing their ability to bring you more and better entertainment.
Communications/television satellites orbit synchronously at an elevation of
about 22,000 miles above the Earth remaining over certain land masses/areas
so that a receiver dish can remain stationary on the side of a home or in a
yard. The advanced research and growth of Dish Network is directly
attributed to their continued enhancements in the area of home
entertainment programming.
Dish Network obtains select programming from providers like Life Time, HBO,
CNN, ESPN, Cinemax, Showtime, STARZ, and other sources. These
providers, also known as 'uplink' sites initially beam their signals to the
satellites. Dish Network's, whose broadcast facility is located in Colorado,
satellites then digitize the signaling for quality, encrypt the signals, and then
transmit a digital high definition rebroadcast to installed receivers in subscriber
homes providing the best in home entertainment services. Each satellite has
what is called a target area or 'footprint', and programming from a given
satellite can only be received within that particular target area or 'footprint'.
The 1980's and 1990's dish receivers were huge, some being about 10 feet
in diameter, but now it is completely portable so it is easy to take your
receiver with you as you travel in recreational vehicles or boats - just place
your dish facing a Southern sky and signals are easily received.
This process allows Dish Network to deliver digital high definition and
standard satellite services all over the world and to offer subscribers over 256
channels of quality programming plus 50 channels of Sirius music in CD quality
clarity. Dish Network offers the most complete and diverse packages
available with premium movie channels, 500 commercial-free movies each
month, excellent sports channels, interactive gaming with local and national
weather and traffic updates, multi-cultural international programming,
educational channels, VOOM high definition channels, and children's and adult
channels. A Parental Lock feature is included for absolute control in family
viewing. Dish Network offers free equipment and installation and specified
services for a limited time. As a gift to first-time subscribers, Dish Network
includes a Digital Video Recorder - free - to further enhance viewing
enjoyment. The DVR allows you to digitally record and store up to 100
hours of programming in 100 percent digital high definition imaging and
sound. This lets the viewer record, fast-forward, rewind, and pause - even
stopping live broadcasting for annoying interruptions - and then resuming

as well as a library of your favorite movies, sports events, or music.
