Fta Satellite TV & Fta Receivers

Author: Jeff Herder

Free-to-air (FTA) is a term used to describe television (TV) and radio broadcasts, which are broadcast, unencrypted and may therefore be picked up via any appropriate receiver. The term should not be confused with free-to-view, which describes TV, which is available without subscription, but which is encoded and may therefore be restricted geographically. Neither of these options can be described as pay-TV, which describes a subscription service, which is encrypted. The term typically refers to delivery by satellite television, but in various parts of the world where encrypted digital terrestrial television channels exist, broadcast on UHF or VHF bands, it can also be applied to those systems.

Satellite Television

Satellite television today is received by most people in developed markets by means of a DBS provider like a DTH platform or Dish TV. The service providers choose programs as is required and send across the same to its customers a predetermined package. The basic aim of the service provider is to give competition to the cable TV by providing hundreds of channels to its customers. The broadcast of the service provider these days, unlike the previous days is completely digital hereby providing extremely high quality video and sound. C-band radio was used in earlier broadcasts that were in the range of 3.4 to 7 GHz frequency. But digital satellite television uses the Ku band frequency of 10 to 14 GHZ. Digital satellite television has five major components. The programming sources are nothing but the channels that are broadcast. The DTH platform does not create its own content rather it broadcasts content of other companies like ESPN or HBO by paying them accordingly. Thus the satellite television service provider acts like a broker between the end viewer and the content provider. This is very similar to the job of a cable television provider. Acting as the hub of the system is the broadcast centre. It receives content from different programming sources and compresses the same and if needed even scrambles it and beams across the signal to the satellites it uses. The satellite in turn receives these signals and rebroadcasts them back to the earth. The dish at the viewer’s house picks up these signals from the sky (one or more satellites in the same part) and sends them to the receiver placed at the viewer’s house. The signals are then processed by the receiver and then sent to the standard television set for viewing.

Satellites and Satellite television

Sunday, February 15th, 2009

While terrestrial television use radio waves to broadcast the signals that originate from the television stations, the satellite TV uses the communications satellite to do the same. In many countries, the satellite TV acts as a supplement to the terrestrial signal, thus giving a wider choice of channels to the viewer. To receive signals of satellite TV, a satellite dish must be purchased, along with a digibox.

The satellites that are used for transmitting the satellite television signals are placed wither in an elliptical or geostationary orbit about 22300 miles above the earth’s equator.

Satellite television is television delivered by way of orbiting communications satellites located 37,000 km above the earth’s surface. The first satellite television signal was relayed from Europe to the Telstar satellite over North America in 1962. The first domestic North American satellite to carry television was Canada’s Anik 1, which was launched in 1973.
