- Working with PIDs
See “Unreferenced PID Mapping” on page 172 for steps on creating reserved PID mapping.
Dummy PIDs
Maintenance and removal of dummy PIDs are described in the following topics:
•
“Guidelines for Dummy PID Configuration,” next.
•
“Deleting Dummy PIDs” on page 166.
Guidelines for Dummy PID Configuration
The following guidelines should be taken into account when configuring data streams that use dummy
PIDs:
1.
You cannot configure a Dummy PID data stream unless an actual data stream has been groomed
to a program in the relevant transport stream.
2.
You cannot delete a program with a data stream to which other dummy PID streams point.
3.
If you are creating multiple dummy PIDs under one program, they must all point to the original
data streams from a single program. You cannot create multiple dummy PIDs in one program that
point to data streams from multiple programs.
4.
You can only reference a dummy PID data stream to a data stream in a program that is within the
same transport stream.
5.
A dummy data PID referenced in a output program will be used regardless of the input source,
such as the originally groomed network program source, during program redundancy or program
substitution service, or during a DPI ad insertion
.
6.
You cannot configure the value in an ES as “Yes” for the
Dummy
field and “Yes” for the
Preconfigure in PMT
field at the same time.
7.
Groom the actual data stream for which you wish to create a dummy PID, from an input program to
a specific output program.
This section contains an example that creates a dummy data PID that is associated to the real data
stream (
):
