System Overview

^=tçêÇ=^Äçìí=i~óÉêë

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-Orderbutton.

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.
