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

Digital satellite Equipment Control.

The outdoor unit comprises the antenna, one or more LNBs polarizers and external components.

DVB

The Digital Video Broadcast group was created to establish a technical frame work for the introduction of digital video broadcasting systems.

EPG

Electronic Programme Guide. A software that enables viewers to navigate easily among the large number of channels provide by digital technology, in order to select the service they desire.

FEC

Forward Error Correction. Correction of faulty bits in the received signal.

GHz

The prefix giga means billion, and Hertz means cycles per second. Signal in the GHz range are often called microwaves.

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).

MPEG

Moving Picture Experts Group. Body established

GB 24

by the international Standards Organization to provide the basis for a picture coding and Compression system.

Network

A number of digital channels transmitted from one source. Grouped under separate headings in the channel list.

Parental control

A feature that allows parents to “lock:” programmes that they consider unsuitable for children. A “locked” channel or programme can only be “unlocked” with the special parental access code.

ACCESS code

Personal Identification Number. A four -digit code stored in the memory. You can change ACCESS code on the “User Preference” Menu.

Polarization

Polarization allows several programmes to be fit into the same frequency band. The signal from the satellite are transmitted either with linear (Vertical or Horizontal ) polarization or circular (right or left) polarization.

Radio Frequency(known as HF in some countries).

SERIAL RS232

A serial communication standard data port.

Satellite dish

A dish-shaped antenna (reflector) that receiver signals from a satellite. The dish focuses the signals into the LNB.

SCART

A 21-pin connector used for connecting the Mediamaster, VCR and TV. Also named Euroconnector or Peritel connector.

Symbol rate

Size of the digital package transmission.

S.W

Software. Program code.

PID:Packet Indentifier.

PCR:Program Clock Reference.

BER:Bit Error Ratio.
