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

Horizontal ) polarization or circular (right or left)
polarization.
RF

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.
