What is a Satellite TV? A satellite TV or satellite television is basically the traditional television that is delivered by ways of communication satellites, compared to the conventional terrestrial televisions and cable televisions. In key areas all across the globe, a satellite tv service supplements the older terrestrial signals, thus providing wider range of services and channels, including those subscription-only services.
History of the satellite TV- The very first television signals were relayed to a Tellstar Satellite from Europe in 1962. The geosynchronous communication satellite that was first introduced was the Syncom 2, launched in 1963. Likewise, the first satellite that was considered as the pioneer in commercial communication satellite tv is call the Intelsat_I, nicknamed as the Early Bird, was launched into orbit April 6 of 1965. On the other hand, the first satellite television for national network was called Orbita, created in 1967 in Soviet Union, and was originally based on a principle that use those a highly elliptical satellite called Molniya. This said satellite is for re-broadcasting, as well as delivering television signals to the ground downlink stations. Furthermore, the Northern American satellite television version named the Anik 1 was launched in 1972, while the ATS-6, the very first Direct Broadcast Satellite, was launched two years after the Anik 1. in 1976, Ekran, the Soviet’s version of a geostationary satellite that carry a Direct-to-home television, was launched in the year 1976.
Standards of the Satellite TV- An analog television set that is distributed thru a satellite is normally sent either scrambled or unscrambled from PAL, NTSC, and SECAM television broadcast standards. Analog signals are generally frequency modulated, converted from FM signals to a baseband. The baseband is the one that comprise video signals and audio sub-carriers of the satellite. The audio sub-carriers are then demodulated to provide raw audio signals. On the other hand, if the signals are digitized television signals, or even multiplex of signals, they are normally QPSK, a type of digital modulation scheme conveying data by either modulating or changing phases of reference signals.
What is DBS?- DBS, or Direct Broadcast Satellites are known as direct satellite tv or direct-to-home television. This is actually a recent development, as far as television distribution is concerned. The direct broadcast satellite either refers to those communication satellites that deliver distinct DBS services or those actual television services. Actually, a direct broadcast satellite service is normally referred as the “mini dish” systems. The modified DBS systems, likewise, can run on a C-band satellite and are used by a number of networks during the past years. Generally, DBS systems are based from proprietary transport stream encoding and encryptions that require proprietary reception equipments. Service providers oftentimes license a lot of manufacturers to provide an equipment that is capable to receive proprietary streams. This said equipment normally uses smart cards as part of its decryption systems and conditional accesses.
Satellite TV by Continent and by Country- Not all countries have direct satellite tv access. Some of the countries that have satellite tv providers are Africa, Canada, Latin America, and the United States. In Asia, some of the countries that have satellite tv are Bangladesh, Malaysia, Japan, Pakistan, and India. It is also available in almost all the countries in Europe, as well as in the United Kingdom and in Ireland. Australia, the New Zealand, and countries in the Middle East and North Africa also has the service of a satellite tv.
If you have a satellite tv of your own and needs to find out about a satellite tv guide, try to visit your local providers.
It is normal to have satellite tv at home, especially if you love to browse to varied movie channels. Compared with the cable and terrestrial televisions, the satellite television is indeed one way to enjoy your movie viewing pleasures.
