ACCESS code
Personal Identification Number. A four -digit code stored in
the memory. You can change ACCESS code on the “User
Preference” Menu.
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.
CA
Conditional Access. A system to control subscriber
access to services, programmes and events.
CA Module
A device for the decoding of scrambled signals
Common Interface
Describes a DVB standard hardware and software
architecture for Conditional Access systems.
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

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.
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.
RF
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 Identifier.
PCR
:Program Clock Reference.
BER:
Bit Error Ratio.
