Maximum Packet Stuffing During Critical Transport Loss Setting is Between 1 and 600
If the ASI output format is set to Remux, the Packet Loss Adjustment is enabled, and
the Maximum Packet Stuffing During Critical Transport Loss in the Deterministic
Remultiplexing Setup controls is set to a value between 1 and 600, then the transport
input muting always occurs after the time has expired if the input is below the noise
cutoff threshold. Until the time expires, the ASI output is maintained using a best
effort mix of the available input content and null packet stuffing, as needed. The
DVB-T sync is maintained until the timer expires. When the timer expires, the ASI
output is muted.

Maximum Packet Stuffing During Critical Transport Loss Setting is Zero
If the RF signal is above the cutoff threshold, but contains corrupt or unusable data
within the stream, and the Maximum Packet Stuffing During Critical Transport Loss
in the Deterministic Remultiplexing Setup controls is set to zero, then the ASI output
will consist of null packet and inserted MIPs capable of maintaining DVB-T
synchronization. The DVB-T synchronization capable output continues indefinitely
while the RF signal is unusable.
