SCR single cable system - Satellite Channel
Router
The single-cable system is used to distribute digital
Sat IF signals (including HDTV) and terrestrial
signals over one cable to up to eight receivers.
There is no limit on the variety of channels, i.e.
the complete range of channels from one or
two satellites is transmitted. Switching and the
transponder selection are undertaken in the feed
system or in the matrix and are controlled by the
receiver using a special DiSEqC™ command
to EN 50494. Each receiver is allocated a fi xed
subscriber frequency over 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 single-cable system satisfi es
the single-cable standard in accordance with
EN 50494, i.e. all components of a single-
cable system that satisfy this standard can be
installed in a satellite system

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.

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 a
single transmission frequency.
Digital transponders simultaneously transmit
several TV and several radio programmes on a
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.

Viterbi rate
The Viterbi rate (code rate, error rate)
characterises the error protection used by the
channel provider. The DVB standard provides
the following values: 1/2 - 2/3 - 3/4 - 5/6 - 7/8
