Satellite Tv – The Rich History Of Satellite Tv And Why You Should Have It In Your Home
For people who are looking for a different type of viewing experience than terrestrial or cable offer, they should try getting television service through communications satellites. Satellite TV is a type of service which gives you a greater array of channels and services, and this means that there are several channels that you must have a subscription to, as well.
Telstar was the first to successfully relay satellite television signal in 1962, from Europe over North America in 1962. A year later, Syncom 2, which was a geosynchronous communication satellite – made its debut around the world. The year 1965 saw the appearance of Early Bird, which was the first commercial satellite to reach synchronous orbit. An additional two years after, Orbita, a Soviet Union company, rebroadcast satellite signals to downlink stations that were ground-based using Molniya elliptical systems. Canada in 1972 offered geostationary Anik 1, becoming the first North American company to do so.
How does it work? Altered from FM to baseband, the frequency modulated analog signal comprises both the audio sub-carrier and the video signal. In most cases, the digitized signal is QPSK. As a general trend, digital TV (which includes those which are transmitted via satellite) are based on MPEG and DVB-S (both open standards). In order to encrypt, scrambling through Conax, Dicicipher, BISS, Irdeto, Viaccess, Nagravision, VideoGuard, PowerVu, and Videocipher are used.
There are three main types of satellite television: direct reception by the reviewer, services through local TV affiliates, and headends reception through one of the locally distributed cables. Hotels and residential homes include the first of the three types, which can either be direct broadcast satellite (DBS) or television receive only (TVRO) types.
As satellite TV offers the best all around digital programming, it is an excellent way for people to seek an alternative to boring analog TV and get better clarity and resolution at the same time. One of the major advantages that satellite TV has in its favor is that it uses Ku band signals, whereas the far less advanced analog uses C-band cables. Satellite TV also guarantees broad coverage and stronger reception. These types of television services are a particularly good alternative if you live in an area that is particularly rural or otherwise doesn’t offer cable services. Unlike traditional cable providers in local areas, satellite TV gives additional subscription offers. Overall, if you are looking for an alternative that offers the most varied programming possibilities, this is the plan for you.
