the High range
Modulator:
Switch in the satellite receiver or video recorder used to con-
nect the television set via antenna cable
Parabolic dish:
Dish, made of metal or coated synthetics, with parabolic
shape, used to focus the electro-magnetic waves transmitted
by the satellite at a focal point.
Polarisation plane:
To better utilise the available frequency range, satellites trans-
mit neighbouring programmes with opposite polarisation (hori-
zontal and vertical or laevorotatory and dextrorotatory). In
order to receive the two polarisation planes either two single
LNCs or one V/H LNC are required.
Receiver: see satellite receiver
Satellite:
Description of the satellite, usually a combination of the name
with the orbital position,
ASTRA 19° East
EUTELSAT 13° East
Satellite receiver:
The signals received and converted by the LNC cannot be
processed by the television set. The signals are processed in
the satellite receiver so that modified audio and video (AV)
signals are available at the receiver outputs that can then be
processed by the television set.
SCART:
A standard plug-in connection used in satellite receivers,
video recorders, television sets and other home electronics
equipment to transmit audio (sound) and video (picture) sig-
nals (AV).
Software update:
Digital television is a new medium that provides improved pic-
ture and sound quality as well as the option of providing inter-
active services. These services are continually being develo-
ped and improved by programme providers. To utilise these
services it may be necessary to update the software of the
digital receiver occasionally.
Transponder:
Located on the satellite, used to process one or more pro-
grammes. In other words, it receives the signal from the
ground station, amplifies the signal and transmits it back to
earth.
Universal LNC:
Used to receive the FFS range (10,70 - 11,70 GHz), BBS
(11,70 - 12,50 GHz) and FFS High Band (12,50 - 12,75 GHz).
This entire 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
Service voltage:
64
