Table versioning
scheme
Normally the version numbers of the PSI/SI tables are incremented by
one for each change. This parameter provides the means to force
outgoing tables to use Odd or Even numbers.
This configuration is used in conjunction with Output Redundancy to
differentiate two sources (Main and Backup) from each other, ensuring
that receivers will detect if a redundancy switch has occurred. Should a
switch occur, the receivers will reprocess the PMT and detect a
potentially new PID line-up.
The drop down box provides three options:
Normal – version numbers are incremented normally
Force Odd – version numbers are incremented using odd numbers
only
Force Even – version numbers are incremented using even numbers
only
CA descriptor
placement
Some STBs have specific requirements on the location of the CA
descriptor in the PMT. By default, the unit will place the CA descriptor
in both Service and Component level in the PMT.
The drop down box provides three options:
Service Level – CA descriptor is in the service loop only
Component Level – CA descriptor is in the component loop only
Service and Component Level – CA descriptor is in both loops
PMT caching
Checking this option ensures that the output will not lose the PMT even
if the stream’s input disappears.
NIT manual version
Forces the NIT version number to the given value
Include EIT
signaling in NIT
Enables the EIT linkage descriptor (0x04) to be excluded or included in
the NIT generation.
If EIT schedule information is present, by default, the system adds a
linkage descriptor in the NIT. If EIT is present in multiple transports,
then according to the DVB standard, the NIT will contain multiple
linkage descriptors.
When all transport streams contain the EIT schedule, some STBs jump
to a different transport when using the EPG, causing the current
program not to be displayed concurrently with the EPG. To prevent this
behavior, we recommend that the linkage descriptor be excluded from
the NIT.
7.6.10 DVB  ATSC, ATSC  DVB Conversion
When the output PSI mode is set to ATSC, some selected information will be translated from
the DVB format to the ATSC format. Also the DVB has a larger reserved PID range than ATSC.
