Setting up Deterministic Remultiplexing 
If output Packet Loss Adjustment is enabled or an input stream fault occurs (for 
example, Common, Regional, or RDCS is corrupted or lost), the ASI output bit rate 
and MIP interval (megaframe) is maintained by insertion of stuffing packets and 
MIPs. This feature allows DVB-T modulator sync to be maintained during brief 
input signal outages or corruption of events. The Deterministic Remultiplexing 
Setup values affect the stream maintenance function of the D9804 MTR. 
Proceed as follows to configure the error handling on remultiplexing output:  
1  From the user interface of the D9804 MTR, click the Setup tab, and then the DM 
setup icon from the sub-page. 
 
2  If Packet Loss Adjustment is enabled and an input stream (Common, Regional, 
or RDCS) fault (corrupted or lost) occurs, you can set the Packet Stuffing Alarm 
Delay
. It controls whether the D9804 MTR issues an immediate or delayed fault 
message to indicate that output stuffing is occurring. You can enter a range from 
0 to 100 one tenths of a second. 
For immediate indication, set to 0. 
For delayed indication, set from 1 to 100, where the value is fault delay in one 
tenths of a second. 
3  In the Maximum Packet Stuffing During Critical Transport Loss field, set the 
maximum duration of output maintenance in the event of a persistent critical 
input fault. A critical input fault condition exists when both CYTS and/or the 
RDTS are corrupted or missing. You can enter a range from 0 to 600 one tenths of 
a second.  
Set to 0 for infinite output. For example, the D9804 MTR provides best effort 
maintenance of bit rate and MIP interval maintenance for unlimited time. 
Set from 1 to 600 to provide the best effort maintenance of bit rate and MIP 
interval maintenance for the configured number in one tenths of a second. The 
output is muted if persistent corruption or loss of input exceeds the configured 
time limit.
