• If you select Row and Column, and the number of columns is less than 4, it will be
automatically adjusted to 4.
• If your number of rows is 10, and you set the number of columns to 20, the number of
rows will be automatically reduced to 5.
The number of rows and columns should be selected based on some understanding of the packet
loss characteristics of the network between the 9223 and the receivers. If you have no statistics
on packet loss, the recommended setting is 20 columns and 5 rows to maximize the correction
capabilities. Most receivers that support SMPTE 2022 FEC provide packet loss/recovery
statistics. After running for a while, if the network is found to be clean, consider reducing the
matrix to 10 rows and 10 columns, which will reduce the overhead.
Completing the Configuration
Once the configuration information is filled in, click on the Apply button to make it active. If
there are no errors, the stream will be created, and the configuration area disappears. If any
errors are detected, they will be displayed at the top of the Apply button.
The following configuration-related errors are flagged:
•
Error: UDP Port/Address conflict with Port
streams with the same destination IP Address and UDP port, on the same Ethernet
interface. Please review your settings. Note that ports with FEC enabled will use either
two or three UDP ports (depending on the FEC settings) – these are checked as well.
•
Maximum number of streams exceeded on this

•

licensing. Please contact support to obtain a license.
If the configuration is successful, the output stream will be added to the Active IP Outputs table.
Active IP Outputs Table
Once the output is created, it is added to the Active IP Outputs table, which has Basic and
Advanced views. This table provides a summary of the configuration and status of the output
stream. An example of this table, in the Basic view, is depicted below
