8 Technical Terms (Glossary)

Antenna cable:
Cable connection between the modulator of the satellite receiver and the antenna input of
the TV set, used as an alternative where no SCART connection is provided.

AV: see SCART

Coaxial cable:
Cable connection between the LNB and the satellite receiver, transmits the signals received
and transmits power supply to the LNBs.

Data compression/MPEG1/MPEG2:
The transmission of an image in accordance with current TV standards (625 lines with a pic-
ture frequency of 50 Hz) results in a digital data volume of 216 Mbit/s. This would require
bandwidths not available in terrestrial or satellite systems. The data volume is thus subjected
to a process of data reduction. MPEG2, which is an expanded development of MPEG1, has
been set in Europe as the worldwide standard for data compression.

Deemphasis:
Making the audio frequency curve conform to the broadcast signal, this is determined by the
transmission parameters of the satellite.

DISEqC:

B

roadcasting - a universal digital transmission technology for video images,

graphics, sound and text, i.e. for data in any conceivable form and in every possible and
appropriate quality.

External unit:
Description for the entire system mounted outdoors, consisting of the parabolic dish antenna
as well as one or more LNBs, to receive signals from one or more satellites.

Frequency:
Physical unit for measuring the number of oscillations per second, expressed in Hertz (Hz) or
cycles per second.
