About iTX Master Control
Functional overview of iTX-MC
The iTX Master Control (iTX-MC) option integrates the Imagestore Master Control processor
(Imagestore 750 or Imagestore-Modular) and an iMC panel (iMC100, iMC200, or iMC300)
with a traditional iTX channel automation system, station router and router controller (see
Figure 1-1).

iTX channel playout automation:
When the iTX-MC option is added to a system, iTX
still drives automation control by managing and playing the schedule’s events. However,
unlike traditional iTX systems, the iTX automation system controls the Imagestore 750
mixer as the playout device as well as an iTX Output Server.
Video source inputs:
With the iTX-MC option, the iTX Output Server acts as a video
server source to the station router by providing the pre-recorded programme content,
which can also contain the usual secondary events like logos, voice-overs...etc.
The station router also receives SDI video inputs from various sources, including live
network feeds, studio feeds and the SDI output of the iTX Output Server.
A/B source mixing and local secondary event insertion:
The Imagestore 750 provides
the A/B switching of signals from the station router based on the scheduled events being
run by the iTX automation system, or the manual operations performed on the iMC master
control panel.
The Imagestore 750 also provides the ability to perform downstream insertion of logo or
voice-over assets which are native to the Imagestore 750.
Traditional master control integration:
The iMC panel is directly connected to the
Imagestore 750 master control and channel branding processor via Ethernet. The
Imagestore 750 is fed A/B program sources by an upstream router, with control from
