Output Rate column of the table. If this box is unchecked, the following additional
control is displayed:
 Bit Rate: Enter the desired NULL padding bit rate, in bits/second. Note that if the
stream data rate peaks over the configured value, data can be dropped, depending on the
peak duration (the BRD will buffer the data for short periods of time, but the MPEG
buffer models may be compromised).
When the Apply button is clicked, the changes entered in the Advanced Configuration area are
implemented, if the BRD is licensed to support them:
 Enabling a stream requires an IP Output license.
 Enabling SMPTE 2022 FEC requires a FEC license.
An error message is displayed at the top of the table if either or both licenses are not available.
IP Outputs Status Tab
The IP Outputs Status tab is depicted below. It has one entry for each available stream:
The following status are reported:
 Off: The stream is not enabled (and is not transmitting).
 OK: The stream is enabled and is transmitting correctly.
 Overflow: The stream is set for NULL Padding with Auto Bit Rate disabled, and the
configured padding rate is not high enough to support the current stream rate. Packets are
being dropped. Either increase the padding rate, or set the port to Auto Bit Rate, or
disable NULL padding.
 Overrun: The overall IP output capacity of the BRD has been exceeded, and packets
are being dropped. This will happen if too many output flows are enabled, especially if
NULL padding is also enabled. Turn off unneeded streams, reduce the NULL padding
rate, or disable NULL padding if possible.
