Bad Video data Video PES stream appears to be invalid. Check if other IRDs
see similar problem on the same program.
Bad Video PTS Excessive jumps or jitter in video PTS values. There may be a
defective uplink encoder or mux.
Content for ASI N/A Program content requested to route to ASI output cannot be
found in over-satellite transport mux. Contact network TOC
and advise.
Content Routing problem ASI transport output bears no program content because a
Content Routing Table has not been loaded from the network
or is corrupt. Contact network TOC.

value less than sum of Threshold + Margin—evaluated
over 10 sec. intervals. Unless the margin setting is incorrect,
this indicates a marginal downlink.
FP email fail An FP Email message was received which was corrupt or
invalid. User should acknowledge the warning to clear, and
then notify the network TOC.
High Error Rate High errored seconds rate, presumably useless signal—
evaluated over 60 sec. intervals. Signal-to-noise ratio is
insufficient or there is severe terrestrial or antenna cross-pol
interference.
High RF level There is carrier lock, but the RF signal level is too high.
ID Tag Mismatch Carrier ID frequency text mismatch. User or network has
entered carrier frequency text or tag site ID incorrectly or unit
is on the wrong carrier.
ID Tags Lost Carrier ID tags disappeared. There may be a failure at the
uplink inserter (UMX5010) or loss of COMPEL
®
PID. See "ID
Tag Mismatch" indication.
Invalid COMPEL Hdr Invalid COMPEL header detected in incoming COMPEL
messages. This will cause the unit to immediately attempt
automatic recovery to a backup preset. The IRD is not set up
for connection to this COMPEL system.
Invalid VBI data fmt VBI data found in PID or video user data in unrecognized or
unsupported format (protocol).
Invalid video format Video format in requested program is not supported.
IP address conflict LAN detected but cannot use because of IP address conflict.
KMS stream lost KMS stream lost after initially detected in this transport
stream. There could be an uplink problem. See also "No KMS
stream" indication.
Lost COMPEL PID Data traffic at designated packet ID (PID) for COMPEL has
been lost for more than two minutes. See "No COMPEL"
indication.
Lost VBI Data FN LM
(N=field number;
M=line number)
VBI data for field N, line M has disappeared. If any is
expected, contact network TOC.
