Satellite Broadcasting – An Overviewby Mansoor Ahmad SEO Expert
Satellite broadcasting can be defined as the distribution of multimedia content or broadcast signals via a satellite network. The signals of broadcast generally originate from a station, including a TV or radio station, and sent via a satellite link in order to get a geostationary artificial satellite to redistribute or retransmit to other predetermined geographic locations through an open or a secure channel. Base stations then receive downlinks, including small home satellite dishes or by base stations owned by the local cable network, to distribute to their customers.
In other words, satellite broadcasting is a system of content distribution that uses signals relayed to and from communication satellites that are received by parabolic antennae that are also called satellite dishes. After this, signals go through a low-noise block converter for conditioning.
A satellite receiver decodes the received signals and then presents them to the user via standard television or satellite radio. In the event of satellite television, the signals coming in are encoded as well as compressed as minimum size so that the provider can bundle more channels into the signals. The user can choose which channel to decode and view. The compression used for digital satellite TV is MPEG compression in order to retain its quality.
It is a service that provides television programming to users by relying on it from a communications satellite orbiting the Earth to the location of the viewers. The signals can be received via an outdoor parabolic antenna that is also known as a satellite dish and a low-noise block downconverter.
A satellite receiver decodes the TV programme for viewing on a TV unit. Receivers can be either external set-top boxes or a built-in TV tuner. This TV provides several channels and services. It is generally the only TV available in several remote geographic areas without any terrestrial television or cable television service.
Modern system signals are relayed from a communication satellite on the Ku band frequencies that need only a small dish less than a meter in diameter. The first satellite TV systems were an obsolete type that is today known as television receive-only. These systems get weaker analog signals from FSS type satellite that needs the use of large 2-3 meter dishes. These systems were known as big dish systems and were highly expensive and less popular.
