150 from 176
is allocated a fi xed subscriber frequency
via which it receives its channels. A twin
receiver requires two such subscriber
frequencies. The transponder selection and
conversion to the subscriber frequencies is
undertaken using special tuner modules,
so-called SCR (Satellite Channel Router),
that are installed in the feed system or in the
matrix.
The Kathrein one cable system satisfi es
the single-cable standard in accordance
with EN 50494, i.e. all the components of a
single-cable system that satisfy this standard
can be installed in a satellite system.
Shoutcast Internet radio

transmissions.
Standard gateway
Is used as an interface between two
networks or computers that are linked via a
router. As a result it is possible to transmit
data.

time.
Subnet mask
Defi nes an IP address range in a subnet
(small independent network).
Symbol Rate
The symbol rate describes the quantity of
data that is transmitted per second. The
symbol rate is measured in MSymbols/s and
is equal to the number of symbols received
per second.
Timeshift function
Time-shifted playback
Transponder
A transponder is a frequency converter
which receives TV and radio signals
broadcast from the earth, converts them
and the rebroadcasts them to the earth at a
different frequency. A satellite has several
transponders.
Analogue transponders transmit only one
TV channel and possibly multiple radio
channels on the transmission frequency.
Digital transponders simultaneously transmit
several TV and several radio programmes
on one transmission frequency. If a
channel provider is broadcasting several
TV channels via a digital transponder, we
refer to the provider's channel package.
The terms "digital transponder" and "channel
package" have the same meaning.
tvtv service
This involves an edited EPG that provides
information for up to 14 days for around
160 broadcasters.
UB - User Band
Each receiver has a frequency, the so-called
UB (Userband) assigned to it.
The frequencies of the UBs have already
been preset for various Kathrein single cable
multi-switch series and infeed systems.
In all other cases the frequency can be
selected as desired from the receiver menu
and must match one of the offered UBs of
the multi-switch that is used.
