2 From the Mode drop-down list, choose the redundancy mode for MPEG over IP
input data.
Choose Manual Data1 or Manual Data2 to only use Data1 or Data2 port for
input data. The remaining redundancy controls below are not applicable.
Choose Backup: Primary Data1 (default) or Backup: Primary Data2 to use Data1
port or Data2 port as the primary data port and if one or more of the selected
triggers occur, it will failover to Data2 or Data1 port (the backup port). The
triggers are selected in the Trigger check boxes below.
Note: If the backup port is in a failed state, a failover will not occur.
3 If Backup: Primary Data1/Data2 is selected as the Mode, choose the redundancy
direction from the Type drop-down list. Choose Revertive to attempt to revert
back to the primary port when using the backup port and the primary port is
active again. Choose Non-Revertive to use the backup port (if active) when the
primary port fails, without reverting back to the primary port under any
circumstances.
4 In the Direct Delay field, set the time to switch from primary to backup data port
after the system detects a failure, in a range from 0 to 10000 milliseconds.
5 In the Revertive Delay field, set the time to wait when reverting back to the
primary port once all the triggers for the primary port are back to normal again,
in a range from 0 to 30 seconds.
Note: If Non-Revertive is selected as the Type, this field does not apply.
6 In the Trigger area, check the program-related conditions that will trigger the
MPEG over IP input redundancy switchover to the backup port. Check the AV
Loss, PMT Loss, or PCR Loss check box to detect the status of the audio/video,
PMT, or PCR loss for the program entry being decoded.
The Link Loss and TS Loss check boxes are non-editable. By default, Ethernet
(Link) loss and transport stream loss will always trigger a redundancy
switchover to the backup port.
Note: If Revertive is selected as the Type, and all the triggers are selected, it will
failover to the backup port when any of the triggers occur and the backup port
has valid content. However, it will not attempt to revert back to the primary port
when the primary port is available again. It will remain on the backup port. This
avoids the constant switching between the two ports since the incoming packet
streams cannot be validated until the switch is made.
