By clicking a stream name a dialog opens displaying an overview of the services available in the stream.
Press the blue information button to display the following information for the service:
Service name:
Shows the name defined for the TV service in the SI service
descriptor. If no SI is present in the stream the service id will be
shown.
Service id:
The ID of the selected service within a transport stream.
Audio silence detection status:
A bulb indicating the audio silence detection status. If no audio
silence detection threshold value has been defined, bulb color will
be gray.
When a threshold value has been defined, bulb color is green
for status OK. If the measured audio level goes below the audio
silence detection threshold value, for more than the duration
specified in the threshold settings, an alarm will be raised, and
the bulb turns red.
Freeze-frame detection status:
A bulb indicating the freeze frame detection status for regular and
color freeze. The freeze-frame error timeout value is set as part
of the stream threshold template associated with each multicast
(refer to the
Multicasts — Stream thresh.
and
Multicasts —
Streams — Edit
views). The different bulb colors are:
White:
Unknown (typically due to the Extractor being unable to
decode video)
Grey:
freeze-frame detection is disabled.
Green:
freeze-frame detection is enabled, no freeze-frame is
detected.
Yellow:
freeze-frame detection is enabled. Two consecutive equal
frames have been detected, but the freeze-frame error timeout
value has not been exceeded.
Red:
freeze-frame is enabled. freeze-frame has been detected
and the freeze-frame error timeout value has been exceeded,
thus resulting in an alarm.
Scrambling status:
A bulb indicating the scrambling check status. Scrambling check
is defined as part of the stream or service threshold template
associated with each multicast (refer to the
Multicasts — Ether-
net thresh.
,
Multicasts — Service thresh.
and
Multicasts —
Streams — Edit
views). The different bulb colors are:
Grey:
Scrambling check is disabled.
Green:
Scrambling check is enabled, and scrambling is in accor-
dance with the user-defined requirement.
Red:
Scrambling check is enabled, and scrambling is not in
accordance with the user-defined requirement; an alarm is active.
