Adding an enhanced SCTE104 message event to a schedule
To add an enhanced SCTE104 message to a schedule, drag and drop the message from the
insertion bar onto a primary event in the Schedule Grid or the Timeline Display. The SCTE104
message will be created as a secondary event. This is represented by a block on the SCTE104
track in the Timeline Display. In the Schedule Grid, iTX nests this secondary event within the
primary event.
You should check and edit the properties of the enhanced SCTE104 message event – in
particular, its time mode and offset – in the Event Editor .
