Setting up Input Information

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 For the Trigger , select 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 fields 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
fail over 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.
