TECHNICAL TERMS
Modulator
Circuit in the satellite receiver or the
VCR, for connection to the tv by means
of an aerial cable.
Mode
determines whether a mono or stereo
program is received.
Multifeed:
ODU, consisting of a dish and several
LNBs for the reception from several sat-
ellites.
ODU (OutDoor Unit):
The equipment installed outside, con-
sisting of parabolic/offset dish and one
or more LNBs for the reception from
one or several satellites.
Parabolic Dish:
Parabolically shaped dish of metal or
covered with plastic for collimation of
the electromagnetic waves radiated
from the satellite, in a focal point..
Polarisation level:
For optimum utilisation of the frequency
ranges available, satellites transmit ad-
jacent programs with opposite polarisa-
tion (horizontal and vertical or turning to
the left or to the right). For the reception
of both polarisation levels two single
LNBs or one V/H-LNB are required.
Receiver: see satellite receiver
Satellite:
Name of the satellite, usually with name
and position in the orbit,
ASTRA 19° East
EUTELSAT 13° East
Satellite receiver:
The signals received and converted by
the LNB cannot be processed by the tv.
In the satellite receiver they are proc-
essed in such a way that at its outputs
there are audio and video signals (AV)
which are transmitted to the tv.
SCART:
Connector at tv-sets, VCRs, satellite re-
ceivers and other entertainment elec-
tronics for the transmission of audio
(sound) and video (picture) signals (AV).
Transponder:
Processes one or several programs at
the satellite, viz. reception of data from
the earth station, amplification and re-
radiation to the earth.
Universal LNB:
Designation for a three-band LNB. For
reception of the areas FFS (10,70 -
11,70 GHz), BBS (11,70 - 12,50 GHz)
and FFS High Band (12,50 - 12,75
GHz). The total area is divided into two
bands:
Low Band: 10,70 - 11,80 GHz; LOF
9750 MHz
High Band: 11,70 - 12,75 GHz; LOF
10600 MHz
Power Supply:
LNBs are supplied with power through
the coaxial cable, the receiver delivering
a voltage of 14 or 18 Volt.
