PCR Program Clock Reference
PID Package Identifier
PIN code Personal Identification Number.
A four-digit code that is used for locking/unlocking, eg
with the parental control feature. Default value is nor-
mally 1234.
PSI Programme Specific Information
Parental control A feature that allows parents to "lock"
programmes that they consider unsuitable for children.
A "locked" programme can only be "unlocked" with the
special secret code (PIN code).
Polarisation Polarisation allows several programmes
to be fitted into the same frequency band. The signals
from a satellite are transmitted either with linear (verti-
cal or horizontal) polarisation or circular (right or left) po-
larisation.
RF Radio frequency (known as HF in some coun-
tries).
RS 232 Serial data port
Satellite dish A dish-shaped antenna (reflector) to re-
ceive signals from a satellite. The dish focuses the sig-
nals on the LNB.
SCART A connector used for connection of e.g.
Mediamasters, video recorders and TV sets. Also
named Euroconnector or Peritel connector.

Glossary of terms
Access Authorisation to use the coding system to
purshase/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 instal-
lation set-up. This gives the opportunity to select be-
tween several different languages to a movie. Amount
of choices is dependent on what is available in the sig-
nal.
CA Conditional Access
Coded satellite TV programme
Some satellite TV programmes (PAY TV) are transmitted
in encoded form; with black screen and no sound. A CA
module and a Smart Card is needed to view such pro-
grammes.

EPG Electronic Programming Guide, programme in-
formation about name, starttime etc.
FEC Forward Error Correction, parameters given by
e.g. the Service provider, TV-guides etc.
GHz Abbreviation for GigaHertz. The prefix giga
means billion, and Hertz means cycles per second. Sig-
nals in the GHz range are often called microwaves.
LNB (low-noise block converter) or LNBF
The LNB is an electronic unit mounted on the satellite
dish. It receives the signals reflected by the dish and con-
verts them to signals that can be used by the Media-
master.
L.O. Local oscillator part of the LNB. It converts from
the satellite frequency down to a frequency acceptable
for the Mediamaster.
Mediamaster A unit that converts the digital satellite sig-
nals from the LNB into audio and video signals. The au-
dio and video signal can be sent to the TV set either via
SCART or via RF (modulator output).
MHz Abbreviation for MegaHertz. The prefix mega
means million, and Hertz means cycles per second.
