Direct to Home Television (DTH)

Direct to home (DTH) television is a wireless system for delivering television programs directly to the viewer’s house. In DTH television, the broadcast signals are transmitted from satellites orbiting the Earth to the viewer’s house. Each satellite is located approximately 35,700 km above the Earth in geosynchronous orbit. These satellites receive the signals from the broadcast stations located on Earth and rebroadcast them to the Earth.
The viewer’s dish picks up the signal from the satellite and passes it on to the receiver located inside the viewer’s house. The receiver processes the signal and passes it on to the television.
The DTH provides more than 200 television channels with excellent quality of reception along with teleshopping, fax and internet facilities. DTH television is used in millions of homes across United States, Europe and South East Asia.
