Manually overriding a scheduled broadcast with a live source
The iTX-MC’s Manual Override mode instructs the iTX automation system to keep running
the schedule’s programming while the live source event is played out on air. Once the live
source event has finished, the broadcast rejoins the schedule already in progress. In other
words, from where it would have been had there not been a live event interruption.
on page 39 demonstrates that when a manual override is executed on the iMC
panel, the scheduled events continue running in the schedule grid and timeline, but the
channel’s actual playout transitions to a Master Control Event named “Roll Under”, which is
added to added to the schedule grid and timeline.
The Roll Under event has an initial default duration, however as the event continues to
playout the Roll Under item expands in the timeline without delaying the other scheduled
events. When the operator chooses to end the Roll Under event, the channel’s playout
transitions back to the scheduled playout event by rejoining the event as if no interruption
had occurred.
