2.4 Description
The cassette is a ”MPTS / QAM”-converter, which converts services (stations)
modulated according to DVB-S / DVB-S2 standard and the transport stream fed
via the LAN interface into one or two QAM-modulated cable signals dependent
on the input and output signal paths. The cassette has one SAT IF input and one
HF output. Additionally it is equipped with a LAN interface and an ASI output
(ASI – Asynchronous Serial Interface acc. DIN EN 50083-9).
The transport stream fed via the LAN socket can be inserted into the transport
stream of the receiving stage via the TPS module. The signal path is set in the menu
items input signal path “
INROUTE
” and output signal path ”
OUTROUTE
”.
2.4.1 Input signal path “INROUTE”
2.4.1.1 Menu setting “1=MA 2=MB”
The transport streams of the receiving stage channel strip “
A
” and of the LAN
input channel strip “
A
” generate optionally the transport stream 1. The transport
stream of the LAN input channel strip “
B
” generate the transport stream 2.
