Freeze-frame error timeout:
The time (in minutes) a freeze-frame error should persist
before the VB7880 will raise an alarm.
Color-freeze noise floor:
It is possible to define how much noise is allowed when per-
forming color-freeze detection. When set to Off, the color-
freeze detection is disabled. When set to
Small change
, only
a small amount of noise is allowed when comparing to the list
of solid colors.
Normal change
is the recommended setting,
whereas selection of
Large change
allows a high amount of
noise, which may result in too many color-freeze alarms.
Color-freeze error timeout:
The time (in seconds) a color-freeze error should persist be-
fore the VB7880 will raise an alarm.
Real-time audio analysis:
Enables real-time loudness extraction for the stream. The
loudness data can be retrieved through the Eii.
Audio silence detection threshold:
Set the threshold for silence detection in decibel below 0
LUFS/LKFS (max volume) Use negative values, 0 disables
alarm.
Audio silence detection timeout:
The value in seconds for when to trigger the audio silence
alarm.
If the OTT Active Testing option is available, additional settings are available, which can be enabled on a
channel-by-channel basis by checking the appropriate checkbox in the channel setup. Depending on
the purchased license, there might be an upper limit as to the number of channel the Active Testing
thresholds can be applied to, this limit is described in the
Edit Threshold
dialog.
To disable a threshold alarm, set the threshold value to -1. This does
not
apply for
Manifest XML size
.
Active testing thresholds
Download speed error:
The maximum allowed difference between profile bitrate and download
bitrate (%). If the difference exceeds the threshold value a bitrate error
alarm will be raised.
Download speed warn:
The maximum allowed difference between profile bitrate and download
bitrate (%). If the difference exceeds the threshold value a bitrate error
warning will be raised.
Actual bitrate min:
The minimum allowed bitrate when measured actual bitrate is compared to
profile bitrate (%). If the actual bitrate goes below the threshold an actual
bitrate alarm will be raised.
Actual bitrate max:
The maximum allowed bitrate when measured actual bitrate is compared
to profile bitrate (%). If the actual bitrate exceeds the threshold an actual
bitrate alarm will be raised.
Sequence age:
The maximum time a manifest can remain unchanged before a manifest
age alarm is raised.
Manifest XML size:
The maximum detected size of the manifest before a manifest size alarm
is raised.
