System Overview
lìíéìí=cäÉñáÄáäáíó
Each Encore Video Processor incorporates one output board, which provides all output
interface functions as well as the blending and data-doubling functions required to support
wide screen applications. Supported output resolutions include:
• Computer output resolutions up to 1600 x 1200
• Analog HDTV resolutions including 720p, 1080I, 1080p
• HDSDI Video
• 2048 x 1080p Digital Cinema video
• Plasma display resolutions.
Output synchronization is supported to lock the output frame rate to an externally applied
NTSC/PAL black burst signal.

Within the Encore system, each mixer has two layers, A and B. For complete flexibility,
each layer can be assigned to either PIP or Key functionality.
A typical single mixer application (plus DSK) is illustrated below.

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.
