- Terrestrial receiver
The terrestrial receiver is a set-top box that permits the reception of digital television. Its components are very similar to a desktop PC. This device is a vital link in the chain of the television system. The goal of a DVBT broadcasting system is to concentrate the hardware requirements at the source to simplify the receivers and makes it as inexpensive as possible. It is usually connected to the TV set or incorporated into the TV set.
The main features of a Digital TV receiver may be classified as follows:
– Decodes the incoming digital signal
– Verifies access rights and security levels
– Displays cinema-quality pictures on the TV set
– Outputs digital surround sound
– Processes and renders Internet and interactive TV services
- Receiver for satellite TV
A satellite TV receiver decodes television programs from satellites so they can be viewed on a television set. Receivers come in two forms. One build can be an external set-top box which is connected to the TV. The second type is built-in television tuner which allows the TV to automatically receive the signal without the need of extra equipment. Satellite television provides a wide range of channels and services. It is the only television available in many remote geographic areas where there is no terrestrial television service or cable television service.
Modern systems signals are relayed from a communications satellite on the Ku band frequencies (12–18 GHz) requiring only a small dish which will be less than a meter in diameter. The first satellite
TV systems were an obsolete type known as television receive-only. These systems received weak analogue signals transmitted in the C-band (4–8 GHz) from FSS type satellites, requiring the use of large 2-3 meter dishes. Consequently, these systems were nicknamed “big dish” systems and were more expensive and less popular.
Early systems used analogue signals, but modern ones use DVBS2 digital signals which allow faster transmission of signals at standard or high-definition. Different receivers are required for both types. Some transmissions and channels are unencrypted and therefore free-to-air or free-to-view, while many other channels are transmitted with encryption requiring the viewer to subscribe and pay a monthly fee to receive the programs.
