Lost IP frames
The number of IP frames lost. I.e. FEC processing has not been able to recover these
frames.
Corrected IP frames
The number of IP frames that were successfully regenerated by the FEC processing.
Duplicated IP frames
The number of IP frames that have been regenerated while also being received correct-
ly. This occurs if the IP frame is received out-of-order with sufficiently long delay (thus
regarded as lost by the FEC processor).
Max Burst Loss Length
The maximum number of consecutive IP frames that have been lost.
Columns(L)
The number of columns used in the FEC matrix of the incoming signal.
Rows(D)
The number of rows used in the FEC matrix of the incoming signal.
Max IP frames delay
The maximum delay of out-of-order IP frames (datagrams).
Latency required
The latency required by the input FEC processor to handle the incoming FEC matrix.
The
Column Stream Status
and
Row Stream Status
fields show the status of the IP stream
carrying the column and row FEC IP datagrams, respectively:
UDP port
The UDP ports receiving the column/row FEC data.
Bitrate
The bitrates of the Column and row FEC data.
RTP sequence errors
Shows the number of disruption in the sequence count of the RTP protocol.
For further details of FEC properties and usage, see Appendix B .

Timeouts in MAC address lookup tables can sometimes cause problems when routing one-way
traffic. The Ping feature is designed to solve this by transmitting a ping message generating
two-way traffic.
