GLOSSARY
C-band A frequency range (3.70-4.20 GHz) used for satellite
broadcasts.
DiSEqC A standard through which it is possible to let a DiSEqC
compatible receiver send a signal over the RF cable to a
switching device to switch between different LNBs or dishes.
The DiSEqC uses the 22 kHz signal to control the switching
device.
Feedhorn A part of the dish which collects the signals from the dish.
The signal is then fed to the LNB(F).
Frequency band A frequency band is a range of frequencies which are
dedicated to a certain usage. In the satellite area, commonly
known bands are the C-band and the Ku-band.
FTA An unscrambled broadcast which you can view without
additional payments to a service provider.
Horizontal In the satellite industry, horizontal is used to indicate the
direction in which the received signal is polarized. Normally
you will find that it is abbreviated as H.
KU-band A frequency range (10.70-18.00 GHz) used by most
European TV satellites.
LNB A device behind the feedhorn which processes the signal
into a format which is understood by the receiver for further
processing
LNBF A LNB with an integrated Feedhorn. So the LNBF comes as
one single unit.
NTSC USA video standard with image format 4:3, 625 lines, 60 Hz
and 4 MHz bandwidth with a total of 6 MHz video channel
width.
PAL European video standard with image format 4:3, 625 lines,
50 Hz and 4 MHz bandwidth with a total of 8 MHz video
channel width.
Polarization Broadcasts are done in a particular frequency band. To make
maximum use of a frequency band and bring you the
maximum number of programs, the broadcasts are polarized
in different ways to fit as many as possible programs into one
frequency band.
RS232 connection A RS232 connection allows you to connect equipment to the
receiver which supports the RS232 protocol.
SCART cable A SCART cable is also known as ‘Peritel’ cable and is
commonly used in Europe to connect the audio and video
equipment. A fully furnished SCART cable has 21 wires
which is at both sides finished with a 21-pin connector.
SMATV A satellite master antenna TV system is a system which
shares the reception resources and is intended for the
distribution of TV and radio signals to the user in one ore
more buildings.
Symbol rate Information in the stream which tells the receiver at which
speed (rate) the transponder sends the digital information
(symbols). The receiver must be able to handle the symbol
rate to process the signal correctly into a correct image.
Transponder Equipment inside a satellite responsible for receiving a single
uplinked channel and rebroadcasting it back to Earth.
Vertical In the satellite industry, vertical is used to indicate the
direction in which the received signal is polarized. Normally
you will find that it is abbreviated as V.
