8.4 Creation of NIT (

able)
The NIT is a transponder table, which includes informationn for direct reception of digital programs.
The NIT processing requires advanced knowledge of DVB standards!
The combined NIT includes all relevant data of all connected headend devicesand contains information about all
receivable programs in the network.
Important:
If possible, place the output channels containing a common NIT on the lowest possible frequencies.
Many receivers begin their search at the lower end of the range and therefore the common NIT is
found as early as possible in the tuning operation. This is particularly relevant if existing systems with
devices from other manufacturers are to be upgraded.
Important:
Create a precise system and programming plan
before
installation/programming.
Important:
If service remapping should be applied, this adjustment has to be done
before
creating the combined
NIT.
Process scheme:
Changes to the NIT table(s) first become effective after closing the PC software.
Please wait approx. 1 min. after closing the PC software until the changes become
effective in all relevant systems.
2.
Create a combined
NIT using the
individual device
parameters
3.
upload the
combined NIT upon
all devices separately
4.
in case of later changes:
- set all devices separately
- create a new combined NIT
- upload the combined NIT
upon all devices separately
1.
set all devices
separately
, store the
parameters and
document them
