3.6.2 FEC Settings
Figure 17. IP TX FEC page
This sub-page will only appear if the unit is enabled with FEC.
FEC Mode: Select "No FEC" to not calculate and send any FEC data.
Select "Column only" to calculate and send one-dimensional FEC data.
Select "Column and Row" to calculate and send two-dimensional FEC
data.
Number of columns (L): Enter number of columns.
Number of rows (D): Enter number of rows.
Select "Column only" to calculate and send one-dimensional FEC data.
Select "Column and Row" to calculate and send two-dimensional FEC
data.
Number of columns (L): Enter number of columns.
Number of rows (D): Enter number of rows.
Note: Please note that the maximum matrix size is 256 (L*D) and
that D is in the range 4 ≤ D ≤ 32. In column only mode L is in the
range 1 ≤ L ≤ 32, while in column and row mode 4 ≤ L ≤ 32. L+D can
not exceed 32.
Note: Please note that FEC column packets are transmitted on UDP
port n+2 and FEC row packets are transmitted on UDP port n+4
where n is the UDP port of the media data. This is in accordance
with Pro-MPEG CoP 3.

Skew: Controls whether to organize the column FEC with or without
skew. When enabling skew, the delay required on the receiver is less
than when transmitting straight columns.
FEC overhead: This number is the overhead in percent caused by the
current FEC configuration.
