B.3.3.1 Limitations
PID Limitations on large MPTS: for incoming MPTS containing more than 30 PMTs
a restriction exists such that any component with a PID larger than the PID of the
31
st
PMT will not be routed to the option cards for transcode, and hence use of that
component will result in a ghost PID on the transcoded output.
Upstream remapping of the PIDs will be required should this limitation affect the
service lineup used in the AVP 4000.
