10.4 Simple local insertion of a progam
This example shows how to set up the following case:
You want to add a locally encoded service to a national multiplex.
1. Put the national feed on port 1.
2. Put the locally encoded feed on port 2.
3. Connect output cable to one of the output ports.
4. On Outputs-
>
Tables configure PAT, CAT, PMT and SDTa to "Playout Regenerated".
5. On the Outputs-
>
Services select "Transmit services by default" from ASI1 to transmit
all services from the national feed. See Section 8.7.2.5 .
6. On the same page select the local service from ASI2 and click the “Transmit selected
service” button to add it to the output.
7. Set up additional SI/PSIP on the Outputs -
>
Tables page. See Section 8.7.2.8 .
NIT
Set NITa/NITo to "Passthrough PID" or "Playout Unchanged"from optional source,
or have NIT on the output.
SDT other and BAT
Set SDTo and BAT to "Playout Unchanged" from optional source. Since you’re
regenerating SDT actual, you cannot choose a passthrough mode on "SDT other"
or BAT (same PID).
EITpfa and EITsa
If you have EIT actual on both the national and local feeds, you can set EITpfa
and/or EITsa to "Playout Regenerated" to include EIT p/f for the local service.
If the local feed doesn’t have EIT, you may just as well set EITpfa and EITsa to
"Playout Unchanged" or "Passthrough PID" from ASI1.
EITpfo and EITso
Set EITpfo to "Playout Unchanged" from ASI1 to play out the other information
from the national feed.
TDT and TOT
Set to "Passthrough PID" from ASI1 to forward TDT and TOT from national feed.
10.5 Sharing of service component
Having the case above, you also need to add signalling of a data component that is signalled
on one or more of the national services, to the locally generated channel. This is illustrated in
figure
10.1 .
