Fingerprint analysis alarms
Alarm name	Relation	Applicability (based on comparison mode)			Alarm state	Description
		Lipsync detect	Video comp	Audio comp
Audio match level	For each audio channel	YES	NO	YES	Normal Match is locked [i.e. Result is conclusive and match level is not below minimum threshold. Text shows match level.]	Audio match level for this channel.
					Fault Match is unlocked [i.e. Result is conclusive and match level is below minimum threshold. Text shows 0.]
					Unknown Match cannot be determined. Check fingerprint presence.
Audio delay1	For each audio channel	YES	NO	YES	Normal Match is locked and delay is not above the configured maximum threshold (default is no maximum). Text shows delay in ms.	Audio delay for this channel.
					Fault Match is locked and delay is above the configured maximum threshold (default is no maximum). Text shows delay in ms.
					Unknown Delay cannot be determined due to match fault.
Weak correlation for audio	For each audio channel	YES	NO	YES	Normal No weak correlation when comparing the Probe's ChX audio content with the Reference's.	Status of weak correlation for the compared channels.
					Fault Weak correlation when comparing the Probe's ChX audio content with the Reference's.
					Unknown Weak correlation not applicable. Check fingerprint presence.
Silent audio	For each audio channel	YES	NO	YES	Normal The audio content on the Probe’s ChX is not completely silent.	Audio silence status for this channel on the Probe.
					Fault The audio content on the Probe’s ChX is completely silent. Text shows fault's start time.
					Unknown Silence cannot be determined on the Probe’s ChX. Check fingerprint presence.
Silent audio on reference	For each audio channel	YES	NO	YES	Normal The audio content on the respective Reference channel is not completely silent.	Audio silence status for the respective channel on the Reference.
					Fault The audio content on the respective Reference channel is completely silent. Text shows fault's start time.
					Unknown Silence cannot be determined on the respective Reference channel. Check fingerprint presence.
Lip-sync delay	For each audio channel	YES	NO	NO	Normal The lip-sync delay computed from video and audio delays is not above the maximum allowed. Text shows delay in ms.	Current lip-sync delay for this channel.
					Fault The lip-sync delay computed from video and audio delays is above the maximum allowed. Text shows delay in ms.
					Unknown Lip-sync delay cannot be determined unless both match alarms are Normal.
Lip-sync delay (last valid)	For each audio channel	YES	NO	NO	Normal The lip-sync delay computed from video and audio delays is not above the maximum allowed. Text shows delay in ms.	Last valid lip-sync delay for this channel.
					Fault The lip-sync delay computed from video and audio delays is above the maximum allowed. Text shows delay in ms.
Video match level	For each probe input	YES	YES	NO	Normal Match is locked, i.e. result is conclusive and match level is not below minimum threshold (default is 50%). Text shows match level.	Video match level for this source.
					Fault Match is unlocked, i.e. result is conclusive and match level is below minimum threshold (default is 50%). Text shows 0.
					Unknown Match cannot be determined. Check fingerprint presence.
Video delay1	For each probe input	YES	YES	NO	Normal Match is locked and delay is not above the configured maximum threshold (default is no maximum). Text shows delay in ms.	Video delay for this source.
					Fault Match is locked and delay is above the configured maximum threshold (default is no maximum). Text shows delay in ms.
					Unknown Delay cannot be determined due to match fault.
Weak correlation for video	For each probe input	YES	YES	NO	Normal No weak correlation when comparing the Probe's video content with the Reference's.	Status of weak correlation for the compared video contents.
					Fault Weak correlation when comparing the Probe's video content with the Reference's. Text shows fault's start time.
					Unknown Weak correlation not applicable. Check fingerprint presence.
Low-motion video	For each probe input	YES	YES	NO	Normal The video content on the Probe is not completely in low motion.	Low motion video status for the Probe content.
					Fault The video content on the Probe is completely in low motion. Text shows fault's start time.
					Unknown Low motion cannot be determined. Check fingerprint presence.
Low-motion video on reference	For each probe input	YES	YES	NO	Normal The video content on the Reference is not completely in low motion.	Low motion video status for the Reference content.
					Fault The video content on the Reference is completely in low motion. Text shows fault's start time.
					Unknown Low motion cannot be determined. Check fingerprint presence.
Fingerprint presence	For each probe input	YES	YES	YES	Normal Fingerprints are received for the Probe input.	Status of the fingerprint presence on this probed input.
					Fault Fingerprints are still not received for the Probe input after at least 5 seconds. Text shows fault's start time.
Reference - Fingerprint presence	For each group	YES	YES	YES	Normal Fingerprints are received for the Reference input.	Status of the fingerprint presence on this reference input.
					Fault Fingerprints are still not received for the Reference input after at least 5 seconds. Text shows fault's start time.
Reference [<probed source in a comparison>]	For each group	YES	YES	YES	Text only. Shows the name of the Reference input.	Name of the reference input within this group.
System status2	For each server	YES	YES	YES	Normal The Fingerprint Analyzer is running and operational.	Status of the Fingerprint Analyzer service.
					Fault The Fingerprint Analyzer is not operational.
Fingerprint analysis configuration status2	For each server	YES	YES	YES	Always Normal. Text shows last modification time.	Status of the fingerprint analysis configuration data (update time, etc)
1. The "program delay" alarms (Audio delay and Video delay) are hidden by default because the delay values may not reflect the actual delays due to the lack of a centralized time source. 2. The System status and Lip-sync configuration status alarms are displayed under Health monitoring/Fingerprint analyzer in the alarm tree.
