Maximum Packet Stuffing During Critical Transport Loss Setting is Between 1 and 600
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 a value between 1 and
600, then the ASI output will consist of null packets and inserted MIPs capable of
maintaining DVB-T synchronization for the specified time. The output is muted after
the Maximum Packet Stuffing During Critical Input Loss timer expires.
