In the User Rate field, enter the output user rate, which is only used if Rate
Control is set to User. You can enter a range from 0 to 206 Mbps.
Note: Output data will be partially or completely lost if the payload (bit rate) of
the transport to be encapsulated is higher than the user-defined output bit rate.

From the Output Mode drop-down list, choose the DPM output mode. With the
exception of No Output and Full DPM Control, selecting a mode will configure
the DPM settings to achieve the specified behavior. In this way, they act as DPM
presets. The Mode Status is changed from Unmodified to Edited by User. We
highly recommend to use either one of these basic modes, or, for advanced setup,
enter the DPM mapping before setting the Output Mode.
Each PE in the Single Program Transport Stream (SPTS) creates its own transport
stream, which includes PAT, CAT, SDT, and PMT tables for one service channel
only, as well as ES PIDs for the PE.
The following table describes each mode:
Output Mode
No Output
Passthrough
Service Channels
Only

Description
The output rate follows that set by the uplink. This setting can be
used if the signal source is ASI. If Null Packet Insertion is set to
Yes, the output bit rate is the same as the input rate (including all
the null packets). If Null Packet Insertion is set to No and the
Output Mode is set to one of the MPTS modes, the output rate is
equal to the payload rate of the transport stream to be
encapsulated, and in most cases, it will be lower than the overall
input rate.
The output rate is specified by the User Rate field. It is
determined by the user setting regardless of the input source.
Null packets are always inserted when the configured output bit
rate is higher than the payload rate of the transport stream to be
encapsulated.
Description
No MPEGoIP output will be generated.
All PEs will be set to Pass and other DPM settings will also be set.
Only service channels will be output.
The output will be identical to the input, except that channels
assigned to PEs and PIDs will be mapped using the DPM settings.
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 saved output MAP
configuration. The output map (for example, output channel PMT)
does not change automatically if the input or channel number is
changed.
