2.4.2.2 Menu setting “1=>ASI MA=OFF”
Transport stream 1 is made available via the ASI output, transport stream 2 via
modulator “
B
”. The signal path via modulator “
A
” (MA) is switched off.
2.4.2.3 Menu setting “2=>ASI MB=OFF”
Transport stream 1 is made available via modulator “
A
”, transport stream 2 via
the ASI output. The signal path via modulator “
B
” (MB) is switched off.
2.4.3 General
The cassette is equipped with two channel strips (“
A
” and “
B
”). The “
A
” channel
strip has a digital SAT tuner and can process both the transport stream fed in via
the LAN interface and the transport stream from the SAT tuner. Using an appro-
priate CA module, encoded services coming from the SAT tuner can be decoded
in channel strip “
A
”. The “
B
” channel strip only processes the transport stream
fed in via the LAN interface. The transport streams are directed to the ASI output
or the output converter depending on the set output signal route “
OUTROUTE
”
via the digital signal processing levels. The HF output signals are sent through
the HF output on the cassette to the output collector. The common output level
of the channel strips can be set in the output collector on the head-end station.
An LED in channel strip “
A
” provides an indication of the signal quality for the
SAT IF input signal and shows whether the modulator of the channel strip is ac-
