Alarm Status Widget
139
Example: Three alarms occur, two of which can be acknowledged without further action, while the other
one is considered an Error. In such a case, the overall alarm status would be Error.
Each channel has one global alarm for its alarms only. The global alarm cannot be configured and is not
exposed in the
Channels/Sources tab. It can only be assigned to a widget component that supports alarm
levels, like a UMD or an Alarm status widget. In the Properties pane, the lists of alarm levels that can be
assigned to a widget component include the item
GlobalAlarm , along with all the individual alarm levels.
You can select this global alarm not only as an alarm status, but also as a text label level. When an
individual alarm is in Error, its friendly name will contribute to the global alarm text value. When the global
alarm level is assigned to an Alarm status widget, the text values for all contributing alarms currently in
Error will be visible.
Alarm Status Widget
Alarm status widgets help you see the status of global alarms, but their use is not limited to this type of
alarms. When any alarm level is assigned to an alarm status widget the status of this alarm will be shown.
When using the global alarm at the text label level, it will display the text value of the alarm, which is a
readable name. Choose from two display modes: cycle and marquee. In cycle mode, the Alarm status
widget displays text from each alarm, one after the other. In marquee mode, the alarm text scrolls across
the widget.
In addition, you can control the cycling speed and the scroll rate by setting the cycling period, in
milliseconds.
Subtitling
Teletext subtitling (WST) can be displayed on the monitor wall, allowing visual monitoring of decoded text
from an analog or SDI video source. The lines of text that are part of the video source metadata are
displayed within the corresponding video window. Teletext subtitling is decoded as described by the ETSI
ETS 300 706 standard.
The WST contains up to 799 pages of displayable data (numbered from page 100 to 899). At any time, only
one page can be decoded per video widget and only one page can be decoded per video source.
Video Formats / Subtitling Types
The following table contains a list of supported formats and their corresponding subtitling types. Available
types are: None, CC608, WST and DTVCC708 (note that DTVCC708 also supports the Legacy CC608).
