A message appears to confirm that you want to resynchronize the output
changes and PIDs to match the selected input programs. Click Yes.
If a conflict occurs and Enable Auto Map for Collision is set to No, a detailed list
of all the conflicts is displayed in the Output Channel and PID Conflicts table
when you click View Conflicts. You can then resolve the conflicts manually. If a
conflict occurs and Enable Auto Map for Collision is set to Yes, a message that
the conflicts will be fixed automatically and the Output Channel and PID
Conflicts table is empty.

For channel conflicts, the system will only automatically change the
duplicated output channel numbers. If both PE actions are set to Map or
XCode, the output channel number of the higher PE is changed. Otherwise,
the output channel number of the mapped and transcoded PE is changed.
The new channel number selected is the next channel number that does not
appear in the current PAT or belong to any other PEs.
OL-31980 -01
Description
This is similar to MAP Passthrough, except that only channels
applied to program entries are available on the output. If the input
is tuned to a valid channel, the PEs are automatically set to Map.
Otherwise, the PEs are automatically set to Drop.
Note: If the PE is mapped, it uses the last valid input. The output
map (for example, output channel PMT) does not change
automatically if the input or channel number is changed.
The output will be generated according to the DPM settings on the
MPEG Digital Program Mapping page. This is a manual control
setting.
The output will be generated using the DPM default settings,
except that the DPM Action will be set to XCode and the
Descrambled mode will be set to Descrambled. If the input is
tuned to a valid channel, the PEs are automatically set to XCode.
Otherwise, the PEs are automatically set to Drop.
Note: If the PE is transcoded, it uses the last valid input. The
output map (for example, output channel PMT) does not change
automatically if the input or channel number is changed.
