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.
