circular left or circular right). Reception of
both types of polarisation requires two
single LNBs or a V/H-LNB (Universal
LNB).
Receiver: see satellite receiver
Satellite:
A designation for the transmitting unit in
space. Most often referred to by name
and position, e.g. ASTRA 19° East,
EUTELSAT 13° East
Satellite receiver:
The signals received and converted by
the LNB cannot be processed by the TV.
The satellite receiver processes them,
and transmits audio and video signals
(AV) to the TV through its outputs.
SCART:
A connector on TV sets, VCRs, satellite
receivers and other entertainment
equipment for transmission of audio
(sound) and video (picture) signals (AV).
Transponder:
Carries out the processing of one or
more programmes from a satellite, i.e.
reception of data from earth station,
amplification and radiation/transmission
to earth.
Universal LNB:
A designation for a three-band LNB. For
reception of the ranges FFS (10.70 -
11.70 GHz), BBS (11.70 - 12.50 GHz)
and FFS High Band (12.50 - 12.75 GHz).
The total range 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 powered through the coaxial
cable to which the receiver supplies a
voltage of 14 or 18 Volt.
Outdoor unit:
A designation for the equipment
mounted outside, consisting of satellite
dish/offset dish and one or more LNBs
for reception of signals from one or more
satellites, and DiSEqC converters, if
any.
Viacces:
Digital coding method.
