GLOSSARY OF TERMS

AGC

Acquisition Gain Control.

Audio system

With digital satellite reception, the sound is transmitted in packages and is elected either in a special audio mode or pre-selected by using the installation set-up. This makes it possible to select between several different languages in a film. The number of choices is dependent on what is available in the signal.

DiSEqC

LNB(Low Noise Block converter)

An electronic unit mounted on the satellite dish. It recovers the signals reflected by the dish and converts them to signal that can be used the mediamaster.

MHz

The prefix mega means million, and Hertz means cycle per second.

Medimaster

A unit that converts the digital satellite signal into audio and video signals. The audio and video signal can be send to the TV set either via SCART or via RF(modulator output).
