Network ID:
This identifies the distribution network (the head end); all transport streams generated or processed in a head
end are given the same network ID.
The following settings must be unique to the relevant device or will be taken account of by only one device in the cascade:
•
IP address:
The IP address of each device must be unique within the IP network.
•
Device within Cascade:
Within a cascade of a maximum of 8 devices, each device must receive a unique ID [1 … 8]. The
serial order due to the ASI cabling is quite irrelevant.
•
Create NIT:
If a blank network information table is created for a device during configuration, the device configured to recei-
ve it will overwrite with the current values all NIT information contained in the transport stream. If this option is configured in
more than one device, it will be the table in the last device which is functional.
•
Create TDT/ TOT:
see above.
If TDT or TOT tables are created for a device during configuration, the device configured to receive it will overwrite with the
current values all the relevant information contained in the transport stream. If this option is configured in more than one
device, it will be the table in the last device which is functional.
•
Program Name:
The program name is the designation of the service taken over via the relevant interface, A to D. If more
than one device is in use, the default setting for each device will automatically generate the program name “Prog A” …
“Prog D”. These names will show in the program tables of the reception devices. They should be unequivocal in
meaning and should therefore be changed to represent the actual situation.
The information on cascades and positions which has been set in the configuration will be the basis for the distribution of the transport
stream over the individual programs (or services) and of the automatic allocation of neutral program names and of A/V PIDs and
service IDs in ascending order. It is possible to change the program names but not the PIDs.

Table 4: Automatically allocated service IDs and PIDs
1)
VTX: Teletext internally generated.
The EMA device has the facility that a teletext carousel can be generated for each particular device. This teletext can be allocated to one or all of
the services being shown. This is an optional function and a charge is made for it.
2
) TTX: Teletext of the external signal at the Video IN ports A … D
