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.
Letter box
This setting allows you to view a widescreen film on a normal TV
in real widescreen format. Note that black banners will appear
on the top and bottom of the screen.
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.
Pan&Scan
This setting allows you to view a widescreen film on a normal TV
without black banners on the top and bottom. Note that some of
the image is cut of to make it fit on your screen.
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.
RS-232 connection
A RS-232 connection allows you to connect equipment to the
receiver which supports the RS-232 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.
SVHS
SVHS (Super-VHS) is a video signal with separated
chrominance and luminance. SVHS is an improvement for the
VHS (composite) video as found on VCR tapes.
