Introduction
Functional overview of an iTX-MC System
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 (figure
1-1 ).
Figure 1-1. iTX-MC system architecture
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.
