2. EXPLANATION OF USED TERMINOLOGY
C-band A frequency range (3.70-4.20 GHz) used for satellite
broadcasts.
CCITT An European committee of the international
Telecommunications Union and makes recommendations for
the distribution of telephone and data distribution.
Clarke Belt The Clarke Belt is a dedicated satellite orbit in which satellites
remain in a fixed position relative to the Earth’s surface.
CI-module/CAM Both names are used for these modules. These modules are
PCMCIAcardswithaslotinwhichyoucaninsertasmart
card.
Common Interface (CI) A DVB standard which defines the software and hardware
requirements for condition access systems.
Conditional Access A system which is used by service providers to control the
subscriber’s access to certain services, programs and events
like Pay TV.
DBS band A signal frequency range (11.70-12.40ghz) intended for direct
TV broadcast by satellite channels.
Decoder A unit that is connected to a satellite receiver in order to
unscramble a picture that is protected by encryption.
Digital Audio Broadcasting Standard which describes the method of transmitting digital
audio.
DiSEqC A standard through which it is possible to let a DiSEqC
compatible receiver send a signal over the RF cable to a
switchingdevicetoswitchbetweendifferentLNBsordishes.
The DiSEqC uses the 22 kHz signal to control the switching
device.
DVB A broadcast standard for digital radio and television, using
MPEG-2 compression. DVB is being supported by all
European manufacturers and broadcasters.
EPG A electronic program guide that comes with the broadcast of a
particular satellite, Note that every station fills the EPG
differently or not, so differences in the EPG are not
necessarily receiver errors.
FEC Is an invisible part of a broadcast.which makes sure that
possible errors in the reception of the satellite signal are
corrected.
Feedhorn A part of the dish which collects the signals from the dish. The
signal is then fed to the LNB(F).
Ferrite A remote controlled device that determines the polarity of the
signal which is fed to the LNB. The ferrite is more or less an
electro-magnetic polarizer.
Fixed Dish A dish antenna that is pointed at one particular satellite.
Free-To-Air broadcast An unscrambled broadcast which you can view without
additional payments to a service provider.
Frequency band A frequency band is a range of frequencies which are dedicate
to a certain usage. In the satellite area, commonly known
bands are the C-band and the Ku-band.
High Definition Television A digital television format, which combines high-resolution
video and theater like sound to create a movie theater quality
TV viewing experience.
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.
