Branding Insertion Options for Intuition XG
Advanced branding from the Intuition XG (including audio embedded in the fill signal) can be
inserted into the program output in several different ways.
Fill/Key Branding Insertion
This example feeds the video source into the Imagestore 750, which performs A/B mixing, DVE
squeezes and basic branding. The Intuition XG’s fill and key outputs also feed rich multi-layered
graphics into one of the Imagestore 750 keying layers, contributing to the final program output.
All audio mixing and processing is performed by the Imagestore 750, although the Intuition XG
can supply voice-overs in its fill signal.

A benefit of fill/key branding insertion is that the graphics device is not in the direct signal path
and will not affect output in the event of a failure. Also both devices can be controlled as a single
“channel processor” by automation and iMC control panels. The main disadvantage is that it is
difficult to synchronize Intuition XG graphics with DVE squeezes.
Downstream Branding Insertion
This example feeds the video source to the Imagestore 750, which performs A/B mixing of video
and audio plus performs advanced audio processing such as Dolby decoding or up-mix. Output
from the Imagestore 750 is then passed downstream into the Intuition XG which performs DVE
squeezes and applies rich multi-layered graphics to give the final program output. The Intuition
XG can also play out and mix audio clips with the program output as embedded audio.
