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.
Low RF Level There is carrier lock, but the RF signal level is too low.
New PAT with Changes The version number on the Program Allocation table has changed and a new
program lineup has been submitted. Changes have been made on uplink
transport mux.
New PMT with Changes The version number on one or more of the Program Map Tables has changed
with a new PID lineup submitted. Changes have been made on uplink transport
mux.
No ASI Stream Corrupt or missing input ASI stream. Only applicable if ASI input is available and
selected. Check connection and source.
No Audio for Port N
(N=audio port number) No "free" otherwise-unassigned audio can be allocated to wildcard-assigned
port N. There may be fewer audio PES streams than installed audio ports. If so,
explicitly assign a desired language descriptor to this audio port.
No Carrier Lock Carrier lock cannot (or has not) been acquired and maintained. Check that
requested settings are correct. Check RF level indication and RF connection.
For new installations, check antenna pointing and polarization.
No COMPEL
Data traffic is detected at designated packet ID (PID) for COMPEL
. However,
no valid COMPEL messages have been detected during the last two minutes.
There may be no connection to the network. If required to maintain a
connection, the unit will eventually attempt an automatic recovery to a backup
preset. To debug, check that the COMPEL system at the uplink is functional and
that the data connection to inserter (such as UMX5010) is good. Also check for
fault indications or functional problems at UMX5010.
No COMPEL PID No traffic detected at designated packet ID (PID) for COMPEL, so no
connection is made to the network. The COMPEL PID setting in the unit may be
incorrect. Also see "No COMPEL indication".
