What is DTH?
Direct-to-Home (DTH) television is a satellite-based television broadcasting technology that delivers television signals directly to individual homes via a small satellite dish and a set-top box (STB). This eliminates the need for cable connections, offering viewers a wider range of channels and greater flexibility in their viewing choices.
How DTH Works
- Satellite Transmission: Television signals are transmitted from a satellite orbiting the Earth to a small satellite dish installed at the viewer’s home.
- Dish Reception: The satellite dish receives the signals and focuses them onto a low-noise block downconverter (LNB).
- Signal Conversion: The LNB converts the satellite signals into a format compatible with the STB.
- STB Processing: The STB decodes the signals, allowing viewers to access and watch television channels.
- TV Display: The STB outputs the decoded signals to a television set, displaying the program content.
Advantages of DTH
