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.
