2.4 Description
The twin transmodulator cassette is a QPSK-converter, which converts all sta
-
tions transmitted according to DVB-S / DVB-S2 standard into two QAM-modu-
lated cable signals. The cassette has two digital SAT inputs and an HF output.
Additionally it is equipped with an ASI input and an ASI output (ASI – Asyn-
chronous Serial Interface acc. DIN EN 50083-9).
The transport stream fed via the ASI socket (TS
ASI
) is inserted into the transport
streams of the receiving stages via the TPS module. In this way data can be
added or removed. The output signal path is set in the menu item "
OUTROUTE
".
