2.4 Description
The cassette is a DVB-S2 / SPTS converter which combines modulated serv-
ices (programmes) in accordance with the DVB-S-/DVB-S2 standard and data
streams supplied via the ASI interface into one data stream in the TPS module.
This is emitted via the LAN interface and can contain up to 16 services. 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. The
resulting data streams from the “
Tuner A
”/“
Tuner B
” channel strips and from the
data streams supplied via the ASI socket (ASI – Asynchronous Serial Interface
according to DIN EN 50083-9) can take up to 16 services and are each as-
signed an IP address. The signal supplied into the ASI input is provided again
via the ASI output.
