Set the de-jittering buffer Latency (delay), in milliseconds. If VBR is selected, you
can enter a range from 110 to 150 milliseconds to set a high buffer latency. If CBR
is selected, you can enter a range from 40 to 150 millis econds, to set a lower
latency for CBR streams.
Setting Up Redundancy Controls for MPEG over IP Input
The Redundancy Configuration area allows you to configure redundancy for MPEG
over IP input when an active port fails due to one of the monitored error conditions
(triggers). The data port 1 is labeled as TS 2 and data port 2 is labeled as TS 3 on the
rear connector panel. For more information, see D9854/D9854-I Receiver Rear
Connector Panel (on page 30).
1
In the Input Setup page (Input > Input Setup), click the IP tab. Refer to the
Redundancy Configuration area.
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 10 000 milliseconds.
