ANC Component
This section describes the parameters associated with the component carrying
ancillary data.
The following parameters are available on the Component tab of the Properties
widget on the Service Configuration page when an ANC stream is selected in the
Outputs widget. The same parameters can be accessed through the
Output/<output name>/Transport Stream ID: <n>/Service List/<service
name>/Component List/<component name> menu on the front panel.

Parameter Values Description
PID 32 to 8190 Sets the packet identifier associated with the component.
Bit Rate Weighting Fixed
Specifies the weight associated to the component in the
Bit Rate Tracking algorithm. For audio stream, this is Fixed
and read only.
5.5.3.4.6 PCR Stream Configuration
The video encoding module can generate a separate PCR stream. The PCR stream
contains timing reference that can be used for decoding the elementary streams
included in the same service as the PCR stream itself. To use the PCR stream as a
timing reference for decoding, set the PCR PID parameter associated with the
service to the PID assigned to the PCR stream.
