Finally we recommend to use the Web-NIT generator for every TS to finally inject the NIT in
every output:
Add each channel step by step and you can also add channels of other QAM Modulators here
(but not there LCN’s) to have a complete Lineup for the Receivers.
Now after we have set the DVB-C Output channels, we can arrange all the MPTS outputs we
want to send to Sub-head ends or simply use them to analyze the QAM outputs by a DekTec
Stream analyzer (which we are selling as well):
Parameters → IP Stream:
This device supports TS to output in IP (16*MPTS) format through the DATA port.
Selecting left the ‘IP Stream’, it will open this setting overview shown as Figure-12 to set/change
the IP out parameters.
The
LCN’s
(Logical
Channel
Numbering)
are processed and transferred along
and within the NIT (Network
Information Table), so this should be
done before you create the NIT –
Which is the mayor Table for tuning
your DVB-Receivers in a fast manner:
The Tuner will extract the NIT on the
first channel it will find and can fast
tune to the center frequencies which
are stored here. Finally the Receiver
can sort all received and stored
channels in the network according to
the LCN- values: No1 comes first, so
we recommend i.e. to put the HD
channels to front in order.
