Adding an Unreferenced PID as an Elementary Stream

You can add an unreferenced PID to an input transport stream. This allows you to manage
unreferenced PID inputs for various applications in the BNP output. Unreferenced PID streams are
those MPEG-2 elementary streams encapsulated in the MPEG-2 SPTS or MPTS, whose PIDs are not
referenced in any PSI (PAT and PMT) tables. These unreferenced PID streams may be purposely inserted
for some special control and applications; they could also result from the stream originator's error.
Unreferenced PIDs can come from the program inputs from GigE interfaces or from ASI inputs. In some
applications, these unreferenced PIDs need to be routed to the appropriate output GigE ports or ASI
ports as pass-through, or with-or-without the PIDs being remapped. In other cases, these unreferenced
PIDs need to be dropped, either because such unreferenced PIDs are not required or the streams are
corrupted.
