Rate Control
Description
User
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.
3 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.
4 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
Description
No Output
No MPEGoIP output will be generated.
Passthrough
All PEs will be set to Pass and other DPM settings will also be set.
Service Channels
Only
Only service channels will be output.
MAP Passthrough
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.
MAP Service
Channels Only
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.
