Using Manual Insert and Manual Override modes
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.
Figure 5-2 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.

Preparing to use iTX-MC’s Manual Override mode
Before attempting to use the iTX-MC’s Manual Override mode, operators should ensure
that the following pre-requisites are satisfied:
1.
Ensure that Automation Enabled button on the iMC panel is de-activated.
2. Ensure that the iMC panel’s transition rate settings (slow, medium, fast) are consistent
with the typical schedule event’s transition rate settings.
3. (Optional) Enable the Output Server’s Cue-to-First-Frame option if you want to view the
first frame of the next iTX clip event in the schedule on the Imagestore 750’s Preset
channel (see
page 2-19 ).
