9 Technical terms
Antenna cable:
Cable used to connect the modulator of the satellite receiver
to the antenna input socket of the television set. Used as an
alternative where no SCART socket is available
AV: see SCART
Channel:
Part of a frequency band, divided and allocated by an agreed
system. A TV channel consists of two frequencies, one for the
audio and one for the visual content. Each channel is descri-
bed in terms of a numeric description (with the exception of
European television channels broadcast in the frequency
band 40-230 MHz, these are denoted by letters).
Data compression/MPEG1/MPEG2:
The transmission of the current television standard (625 lines,
and a picture frequency of 50 Hz) results in a digital data
volume of 216 MBit/s.
This would require enormous bandwidths which are simply
not available, whether via satellite of via terrestrial reception.
Therefore the data is compressed in order to achieve a
reduction in the data volume. For Europe,MPEG-2 has been
laid down as the world-wide standard for data compression.
MPEG2 is an expanded version of MPEG1
Coaxial cable:
Cable used to connect the LNC to the satellite receiver, used
to transmit the signal received as well as to provide power to
the LNC.
DVB:

nology used to transmit pictures, graphics, sound and text,
i.e. data in any form imaginable form, in appropriate quality.

A physical term, indicates the number of vibrations per
