7.6 Block diagram / product architecture
This unit has 4 scaling engines and 4 keyers whose outputs are mixed together
(with an optional background / cascade input) to form a single image, as in the
block diagram below:
As the diagram shows, the 4 inputs are available for use by any of the scalers. A
5
th
DVI-I input acts as a ‘lock source’ (also known as window Z), which can be used
for background / cascading.
Windows A, B, C & D can be scaled (which is any combination of Zoom, Shrink,
Flip, etc. available in Adjust windows), and then each window (A, B, C, D or even Z)
can be keyed to remove any color (or nearby range of colors) using the Adjust
keyers menu.
The resulting windows are merged together into a single output, according to the
layer priority as set in Adjust windows.
Not shown in the above diagram are the Still Image Stores (SIS1 through to SIS4)
which can provide a static source for the Windows A through D (but not background
Z), nor the border generators which can place borders of any color or opacity
around each window.
5 of the 50 Presets (numbers 6 through 10) built into the unit have been pre-defined
with various sample settings to show some of the available configurations, but can
be overridden by the user.
