System Overview

Within the Encore system, each mixer has two layers, A and B, and each can be assigned 
to either PIP or Key functionality.

A typical single mixer application (including the DSK) is illustrated below.

Figure 1-4.  Layer Illustration — Background, Single Mixer + DSK

Please note the following important points:

The Downstream Key (DSK) is the highest priority layer, using an unscaled DVI 
input or a scaled frame grab.  The DSK visually appears over all other images 
(PIPs and keys) on all mixers.  

The high resolution Background layer has the lowest priority, using an unscaled 
DVI input or a scaled frame grab.  This layer visually appears behind all other 
PIPs, keys, and the DSK.  The system can transition between two background 
sources — both of which must be at the projector’s native resolution.  

On any mixer, a PIP layer appears over backgrounds and under the DSK.  Effects 
include mixes and wipes, smooth moves and resizing, adjustable aspect ratio, 
borders, drop shadows and soft edges, and PIP “clone” mode (mirror and offset). 

On any mixer, a Key layer also appears over backgrounds and under the DSK.  
Key effects include luminance keys, split keys (key alpha and fill), invert keys and 
color keys (graphics).  

Within a single mixer, layer B has priority over layer A, but you can change that 
priority as desired by pressing the Swap Z-Order button.  

On a triple mixer system, up to six inputs can be scaled to produce PIP or Key 
images that can be transitioned independently or in pairs.
