We are referring to broadcast television through communication satellites, which is different from traditional television and cable television. Satellite TV offers a much wider variety of services and channels, including subscription-only channels.

Telstar satellite successfully sent a relay satellite television signal in 1962 from North America to Europe. Following the trend, in 1963, Syncom 2, a geosynchronous communication satellite, premiered as well around the world. The Early Bird was the first commercial appearance of a synchronous orbiting satellite, and that occurred in 1965. Orbita was created by the Soviet Union in 1967 and functioned by redelivering and re-broadcasting television signals to ground stations through the usage of Molniya elliptical systems. In North America, Canada was first to carry geostationary Anik 1 (in 1972).

How does it work? Altered from FM to baseband, the frequency modulated analog signal comprises both the audio sub-carrier and the video signal. The digitized format of the television signal is QPSK. Digital television - including those which are transmitted via satellite- are based on a type of open standard such as MPEG and DVB-S. It is necessary to both scramble and access types of encryption, and this is done through Videocypher, BISS, VideoGuard, Digicipher, BISS, Conax, Irdeto, Viaccess, and PowerVu.

Three examples of satellite television exist: reception that is direct by the viewer, service through local TV affiliates, and headeneds reception. For these areas, they can receive either DBS, a.k.a. direct broadcast satellite or TVRO, a.k.a. television receive only.

Satellite TV is often chosen over analog TV because of the advantages it offers, two of which include advanced clarity and resolution. You get a superior product in satellite TV because it uses superior equipment such as advanced digital equipment and Ku band signals, though analog uses C-band cables, which are already outdated. Satellite TV also guarantees broad coverage and stronger reception. This is the kind of TV for anyone who lives in a rural area, or any other place where cable TV is restricted. Satellite TV likewise offers more options in terms of subscription ? you can actually choose from among many different retailer companies (never get stuck with the only cable provider in your area). For anyone looking for a variety of programming options, this is what you are looking for.
