esCriPtion
The cassette is a DVB-S2 / SPTS converter which combines modulated services
(programmes) in accordance with the DVB-S-/DVB-S2 standard into one data
stream in the TPS module. From this up to 12 data streams, containing one
service each, are emitted at the LAN interface. For operating the cassette in a
LAN network it can be assigned its own IP address. The cassette is equipped
with two tuners. The accompanying channel strips consist of the digital SAT
tuners and the digital signal processing levels. From the resulting data streams
of the "
Tuner A
" and "
Tuner B
" channel strips up to 12 services can be taken
and assigned with each an IP address.

The channel strip "
Tuner A
" can descramble scrambled channels via a cor-
responding CA module. Two LEDs provide an indication of the signal quality
with their colour. The transmission of the DVB service information EIT as well
as teletext (TXT), subtitle (SUB) and AC3 tone can be individually activated or
deactivated.

For each service, event information is transmitted (such as starting
time, duration, scrambling etc.).
