Ad triggering

Notice

Dynamic ad-triggering (SCTE-35) requires a q.air Premium subscription.

The dynamic ad-triggering feature enables you to signal ad insertion opportunities that can be used by downstream systems to automatically replace these parts of your content.

The underlying workflow is based on the SCTE-35 standard and enables you to schedule splicing event trigger points in your program that are afterwards included in the playout output data stream. These splicing trigger points can be evaluated by downstream systems to perform server-side or player-side ad insertion. In addition to ad insertion, SCTE-35-based splicing events can be used for various other purposes. E.g. for regional content variations, for blanking content on the web or to trigger recording servers.

Shortly before a splicing event is sent by the playout, the event itself is announced. For this purpose additional information is included in the playout output stream. The time interval for announcing the upcoming splicing event is configurable and usually set between one and four seconds before the start of the actual event.

Depending on its properties a splicing event can be stopped either automatically or manually. For an automatic splicing event the end event trigger is automatically sent when the playback of the corresponding clip or show is finished. A manual splicing event has to be stopped manually by an operator.

In q.air you can add and manage splicing events in the following ways:

  • use q.air Traffic to add splicing events to clips or shows already when you create/schedule playlists

  • use q.air Automation for last minute changes
