Scheduling Conflicts and Ripple

You can schedule several types of events at once, as long as they do not conflict with one another.  For example, you can schedule a playout and an overlay to run at the same time.  Likewise you can run a playout on one channel and a live stream on another channel.  Scheduling a playout and a live stream for the same channel at the same time, however, can cause a conflict.

If you schedule a conflict, the application will offer you options.  Not all options are possible for all conflicts.

  • Start Late – No other events are altered. the event being scheduled will shorten to the available duration by starting later into the file, and playing to the end.
  • End Early -No other events are altered. the event being scheduled will shorten to the available duration by ending early, but will start at the beginning.
  • Ripple Conflicts Forward – fit the event into the schedule and push everything else forward.  This is a useful option if the playout overlaps the next event by just a few seconds. However, rippling switch events forward means they will start later than originally scheduled.For example, suppose you scheduled a switch event to a live feed from town hall so you could broadcast the mayor’s speech at 10:00 AM.  Then suppose you schedule a playout at 8:00 AM that creates a 5-minute conflict.

    Ripple stops at midnight. If an earlier event is rippled, then any event scheduled over the midnight hour will end at midnight, even if there is a schedule gap at 00:00:00. Event beyond midnight will be unscheduled.

    If you ripple an event at 19:00:00 so the next event starts at 20:00:05, then all subsequent playouts will start 5 seconds late until midnight or until the web application finds a gap of 5 or more seconds, whichever comes first.Ripple pushes playout, stream, and AIO input events forward, but not overlay events.

  • Ripple Conflicts Backward – If there is an empty time slot before the conflict, this will move the event earlier into the schedule.
  • Cancel Conflicting – Removes any event that was scheduled for the same time of the event you just tried to schedule.  It might be best to begin again, especially if you did not expect a conflict.  For example, you might have scheduled a playout for the wrong channel.
  • Abort Operation – Cancels the change you were about to make.
