GLOSSARY OF TERMS

Access

Authorisation to use the coding system to purchase / order TV programmes.

AGC

Automatic Gain Control.

Audio system

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

CA

Conditional Access. A system to control subscriber ac- cess to services, programmes and events.

CA module

A device for the decoding of scrambled signals.

Common Interface

Describes a DVB standard hardware and software archi- tecture for Conditional Access systems.

DVB

The Digital Video Broadcast group was created to estab- lish a technical framework 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 provided by digital technology, in order to se- lect 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. Signals in the GHz range are often called micro- waves.

LNB (low-noise block converter) or LNBF

An electronic unit mounted on the satellite dish. It re- ceives the signals reflected by the dish and converts them to signals that can be used by the Mediamaster.

L.O.

Local oscillator part of the LNB. It converts from the sat- ellite frequency down to a frequency acceptable for the Mediamaster.

Mediamaster

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

MHz

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

MPEG

Moving Picture Experts Group. Body established by the International Standards Organisation to provide the ba- sis for a picture coding and compression system.

Network

PCMCIA

Personal Computer Memory Card International Associa- tion. The Common Interface slot follows this standard.

PCR

Program Clock Reference.

PIN code

Personal Identification Number. A four-digit code stored in the Smartcard. For PPV (Pay Per View) or other serv- ices together with the subscription.

Polarization

Polarization allows several programmes to be fit into the same frequency band. The signals from a satellite are transmitted either with linear (vertical or horizontal) po- larization or circular (right or left) polarization.

RF

Radio frequency (known as HF in some countries).

SERIAL RS 232

A serial communication standard data port.

Satellite dish

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

SCART

A21-pin connector used for connection of the Mediamaster,VCR and TV. Also named Euroconnector or Peritel connector.

Scrambled satellite TV programme

Some satellite TV programmes are transmitted in scram- bled form. A Smartcard, and possibly a CA module, will be needed to view such programmes.

Service provider

Is a company that collects a number of programms/serv- ices and distributes them to customers.

SNR

Signal to Noice Ratio. Signal quality measure.

S/PDIF

Sony/Philips digital interface format. Digital audio output.

Symbol rate

Size of the digital package transmission

SW

Software. Programme code.

TS

Transport stream.

VCR

Video Cassette Recorder.
