The 1U Indigo 1 or FR1AV frame will house six modules and a single power supply.
The 1U Indigo DT desk top box has a built-in power supply and will house up to two
modules.
On the 1U, 2U and 4U frames a hinged front panel gives access to the PSU and all
modules. The desk top box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.
Applications include correcting computer-generated or post-production output and
ensuring broadcast colour gamut is always legal.
Processing modes
Advance/retard Y/C offset delay
Advance/retard overall horizontal delay (74ns increments)
Hue shift UV channels
Increase/decrease Y, U and V channel lift and gain independently
Set and soft limit Y channel positive (Hi) and negative (Lo) excursions
Set and soft limit U, and V channel positive/negative excursions symmetrically

Soft limiting
Soft limiting or clipping is provided by a combination of adjustable threshold and slope
controls. The luminance channel has both high and low limiting, whilst the UV and RGB
channels have one clipping control for each colour component. UV clipping operates
symmetrically about black level and RGB clipping is adjustable at the high level only.
