3  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 milliseconds, 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 D9824 Receiver Rear Connector 
Panel
 (on page 19). 
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 in 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.
