1-6 Vertigo XG & iTX Integration User Guide
Integration of Vertigo XG & iTX
Xmedia Server. The Xmedia Server then publishes the page and its associated graphics
files to the Vertigo XG device.
In addition to templates and pages, the VertigoXG plugin associated with the iTX Desktop
also allows users to browse for standalone scenes stored on the Xmedia Server. Like the
scene-side of a template, scenes contain the collection of graphic objects that will be
displayed on air during playout. Standalone scenes are appropriate if the scene’s objects
and playout do not require any control logic (static and/or timed playout). However, if the
scene’s objects are to be data driven or controlled during playout, the scene should be
associated with a template. See the Xstudio User Manual for more information about using
Xstudio to create standalone scene assets.
Processing and playout of video & graphics
For system resilience, we recommend an independent control setup where the backup
channel is configured to use a different Vertigo XG device and commands are always sent
from both the Main and Backup channels regardless of which one is Master.
Using the Vertigo XG plugin in the iTX Desktop, graphics pages are added to the channel’s
schedule or timeline as a secondary event.
TXPlay controls schedule playout. It sends commands through the Playout Server to the
iTX Player (Pandora) to play out events at specified times. An event can feature one or two
video sources, from which iTX produces an SDI or HD SDI output signal. The output signal
is then fed to the Vertigo XG device’s input.
When an XG event (Vertigo page or scene) is encountered in the schedule, TXPlay uses
the Oxtel protocol to instruct the Vertigo XG’s Xplay to cue and take the page or scene.
Xplay processes the page requirements and sends playout commands to the XG Renderer.
The XG Renderer loads the page/scene and its associated graphics. The XG Renderer and
the GPU renders the graphics with the video streams and outputs a single rendered video
stream to air.
For events that do not feature a Vertigo page or scene (XG Event), the video streams simply
pass through the Vertigo XG.
