Meaning / Possible Cause
Unable to switch to backup software from network com-
mand, usually because that software image is not available
or corrupted.
ASI Transport output has been muted per user or network
command.
Requested audio PES stream for port N is invalid or cannot
be decompressed or processed. There may be a problem in
the hardware for that audio port or in the uplink Encoder.
Audio port N PES data buffer overflow. Audio PES data
being delivered faster than can be decompressed. There may
be a problem with the STC at uplink Mux or in the IRD.
Audio port N PES data not available (buffer underflow).
here may be a problem in the hardware for that audio port or
in the uplink encoder. Check that PTS values in the audio
stream do not grossly lead PCR.
No audio PID found in PMT with assigned language
descriptor for hard-assigned port N. Check that the language
descriptor requested by the user or network is actually
assigned to an existing audio stream.
Audio PID found in PMT with requested language descriptor
but no PES data detected. Check uplink encoder.
Auto-recovery in progress. This may be caused by any of
the following problems on a previously commanded or suc-
cessfully acquired transport stream: (1) IRD unable to
deliver services for time exceeding Services Recovery Tim-
eout; (2) IRD required to maintain connection to
COMPEL  and IRD has not detected COMPEL for time
exceeding Network Recovery Timeout; or (3) IRD detects
invalid incoming COMPEL header.
Excessive jumps or jitter in Audio port N PTS values
One or more Program Map Tables are corrupted. See "No
PMT" indication.
Serial number read from secure processor does not match
unit. There may be a an attempt at piracy, a defective
NVRAM memory, or a defective secure processor.
VBI data for field N, line M is unrecognized or in an unsup-
ported format. Contact TOC to confirm that the version of
application code in your IRD is current.
