Satelliitvastuvõtja

Satelliitvastuvõtja, commonly known as a satellite receiver or set-top box, is an electronic device used to receive satellite television broadcast signals. These signals are transmitted from geostationary satellites orbiting the Earth and are then picked up by a satellite dish, which focuses the signal onto a low-noise block downconverter (LNB). The LNB amplifies the weak signal and shifts its frequency to a range that the receiver can process.

The satellite receiver then decodes the digital signal, which may be encrypted or unencrypted, and converts it into a format that can be displayed on a television. Modern satellite receivers are capable of handling high-definition (HD) and ultra-high-definition (UHD) signals, as well as various audio formats. They often include features like electronic program guides (EPGs), parental controls, and the ability to record programs onto an external storage device or an internal hard drive (PVR - Personal Video Recorder).

The receiver connects to the television via cables such as HDMI, component, or composite. It is powered by a power adapter and requires a connection to the satellite dish via coaxial cable. The user interacts with the receiver through a remote control, selecting channels, navigating menus, and accessing additional features. Satellite receivers are essential components for accessing satellite television services worldwide.
