System Overview
A typical ScreenPRO-II Controller application is illustrated below.
Figure 1-2. Layer Illustration — Background, Mixer and DSK
Please note the following important points:
•
The full screen LOGO is the highest priority layer. The LOGO visually appears
“over” all other images, including backgrounds, PIPs, keys and the DSK.
•
The Downstream Key ( DSK ) is the second highest priority layer. It visually
appears over all PIPs, keys and backgrounds — but it is “under” the LOGO .
•
The high resolution Background layer has the lowest priority. This layer visually
appears “behind” all other PIPs, keys, and the DSK. The controller can transition
between two background sources — both of which must be provided at native
projector resolution.
•
A PIP layer appears “over” backgrounds and “under” the DSK and LOGO . Effects
include mixes, wipes, linear moves, resizing, adjustable aspect ratio, borders,
drop shadows and soft edges.
•
A Key layer also appears “over” backgrounds and “under” the DSK and LOGO .
Key effects include luminance keys, split keys (key alpha and fill), reverse key
(key on background), and color key (graphics).
•
Within the mixer, layer B has priority over layer A , but you can change that priority
with the Swap Z-Order button.
•
Up to eight analog inputs and up to two SD/HD SDI inputs can be scaled to
produce PIPs or Keys.
