No Def for Mapping
ASI transport output bears no program content because an Output Definition
Table has not been loaded from the network. Contact network TOC.
No DHCP Server Found IRD is required to get IP settings from DHCP server but none are detected on
the LAN.
No Genlock Sync
IRD supports and has genlock option installed and enabled, but no video
reference sync is detected.
No ID Tag Found
No carrier ID tags in COMPEL
stream. Set IRD not to expect ID tags or check
uplink UMX5010.
No KMS Stream
No KMS stream detected since transport stream acquisition. Unit will not be
authorized if not connected to the KMS stream. Check that KMS PID is set
correctly in unit. If okay, check the uplink.
No LAN Detected
No Ethernet LAN connection. Check LEDs on rear and check other devices on
the LAN.
No PAT
No Program Allocation Table detected in input carrier (or terrestrial interface).
Check that legal ISO transport is available from uplink mux. Often, this
indication may appear when the connection between the uplink transport mux
and the DVB modulator is lost.
No PCR
No Program Clock Reference found, either in video or stand-alone PID. Check
uplink mux or that program's encoder.
No PMT
No Program Map Table found for a program listed in PAT. This could be a fault
in the uplink mux.
No RF Signal
No carrier lock with low RF signal power indication. There may be a
disconnected RF signal. Check connection and check that LNB has DC power.
No SDT Entry
No Service Descriptor Table, or the table is corrupt or missing proper entries.
Uplink mux may not support this DVB feature or may have fault.
No Valid Software
No valid application software available in either the primary or backup flash
positions. Unit will need service.
No VBI Data FN LM
(N=field number;
M=line number)
VBI data not found in video user data or PID for Field N line M If any is
expected, contact network TOC.
PAT Disappeared
Formerly valid Program Allocation Table ceases to be received or becomes
corrupt. See "No PAT" indication.
PAT Version Changed
Version number in Program Allocation Table has changed but no change to
program lineup.
PCR Disappeared
Formerly valid Program Clock Reference ceases to be received or becomes
corrupt. See "No PCR" indication.
PCR Jitter
Excessive jitter in Program Clock Reference values. This may degrade timing
of output video signals. Check uplink encoder for that program.
