FEC Discard
To reduce network latency, the FEC Discard parameter can ignore SMPTE‐2022‐2 input. The default
setting is Disable, meaning the module normally detects SMPTE‐2022‐2 input. FEC Discard is only visible
when the Primary Source or Secondary Source is EXT IP and Control > IP LAN > Data Eth Protection is
not
configured to Seamless.
When the FEC Discard parameter is set to Enable, the delay through the decoder RTP receive buffer is
set to two transport stream packets only.
Transport Stream Errors and Errored Seconds
Transport Stream Errors counts the number of errors; Errored Seconds reports the number of seconds
in error. The transport stream errors detected and counted are continuity count errors, PSI packet CRC
errors, corrupted transport packet headers, and— in some rare cases—overflows of processed packet
queues.
Primary and Secondary IP
Use the IP Receive Port Number to set the IP receive port when the Source is set to external IP.
Use the Multicast Group field to configure the multicast group address, along with the addresses of the
Primary Multicast Source and Secondary Multicast Source.
Status ASI
Read‐only parameters report the Loss of Signal (shown as Fault, No Fault, or Not Applicable), number of
Errors, and Format (shown as ASI‐188, ASI‐204, or Unknown).
Status IP
The Primary and Secondary IP Failure parameter detects an error condition on the primary or secondary
input for this channel. When an error is detected, the parameter reports LAN interface not configured,
Invalid multicast address, or Unstable source.
The Received IP Rate indicates the received IP data rate from the selected IP interface for this channel,
in Mbits/sec.
If FEC is detected, the Corrected and Uncorrected Error counters will indicate number of packets
corrected by FEC and the number of packets that could not be corrected.
If RTP is present, the Reordered Packets parameter reports the number of packets reordered.
