4 The generation of the FEC packets is based on the use of a matrix. The matrix
size is defined by the Length (L) and Depth (D) parameters. In the FEC Columns
(L) field, set the spacing between non-consecutive packets used to calculate the
FEC packet (1 to 20).
If the
FEC Mode is set to 2D , set the depth of the matrix in the FEC Rows (D)
field (4 to 20).
Note: For additional restrictions on L and D values (depending on the FEC
Scheme and FEC Mode ), refer to Pro-MPEG FEC COP#3 and SMPTE-2022.
5 In the FEC Columns UDP Port field, enter the UDP port number for the FEC
Columns stream (2 to 65534, even number only).
Note: We recommend that you set the FEC Columns UDP Port number to TS
UDP port + 2.
If the
FEC Mode is set to 2D , enter the destination UDP port number for the FEC
Rows stream in the FEC Rows UDP Port field (2 to 65534, even number only).
Note: We recommend that you set the FEC Rows UDP Port number to TS UDP
port +4.

View ing Stream Details
To view the stream details, click Stream Details in the MPEG over IP Output Main
or Stream page. The following Stream Status table is displayed.
The Stream Status table displays the status of the streams for the data port,
including the content overflow and link overflow statuses. The FEC Encoder
Overhead displays the FEC overhead, compared to the transport stream bit rate, in
percentage. The FEC Latency column displays the transport stream delay introduced
by the FEC encoder, in milliseconds.
