Configuring the off-air behavior
The Off Air Behavior settings define what the card will do if you force the broadcast off air or
something goes wrong during the broadcast such as a loss of media, an empty playlist, a
missing asset, or a hardware or software crash, for example. Whenever you do not have a
primary event on air, it is considered an off-air situation.
When the card encounters an off-air situation, one of the following occurs:
• If the card was forced off air and no primary events are available in the playlist, the
configured Off Air Action is triggered immediately.
• If no primary event is on air but primary events are available in the playlist, there is a 3
second delay before the configured Off Air Action is triggered. During the first 2
seconds of the delay, the last frame of the last played clip remains on air. This allows
time for the card to resume the playout, if possible. If the card is unable to resume
playout after 2 seconds, it switches to a black screen for 1 second before triggering the
configured Off Air Action.
The Off Air Action can be configured to output a black screen, output a live feed, or output
a full-screen slide that announces that the broadcast is off-air. The Off Air Action can
activate even in the event of a complete hardware or software crash.
If the off-air situation is still not resolved 30 seconds after the Off Air Action was triggered,
the action selected in the Off Air Recovery list is applied. If a primary event is pending such
as a failed event is being restarted, the card will delay triggering the Off Air Recovery for up
to 30 seconds to allow the possibility of a successful resumption of the playout. Once the
Off Air Recovery is triggered, the Off Air Recovery event continues until valid on-air
programming resumes.
The screen graphic used as the off-air slide should be full-screen, in the required video
standard for the channel, and be in OXT format. The SSP-3801 card contains some samples
of off-air slides in various video standards in the FTP location /mediacache/push, which can
be accessed by using local:// in the path. To use a sample slide, choose the slide with the
appropriate video standard for your channel and type one of the following paths in the Off
Air Slide field:
• local://ApologySlide1080.oxt
• local://ApologySlide720.oxt
• local://ApologySlideNTSC.oxt
• local://ApologySlidePAL.oxt
IMPORTANT:
When the SSP-3801 card is registered with GV STRATUS Playout, then GV
STRATUS Playout overwrites any Channel Configuration changes made
through the card’s web interface any time it updates the card with its own
changes.
