System Overview
qÜÉ=båÅçêÉ=sáÇÉç=mêçÅÉëëçê
The Encore Video Processor is a compact chassis that provides the Encore Presentation
System’s input and output circuitry. Two models are available:
The “standard” Video Processor (VP) is a full-featured model that includes all
input, output, genlock and link circuitry.
The VPx is a VP with a reduced set of inputs (DVI only). The VPx is used for
widescreen configurations, and a special widescreen “preview” configuration.
VPx includes all output and link circuitry, no genlock circuitry, and only a small
subset of the standard VP’s input circuitry.
Both units provide a 3RU rack-mount chassis that can be configured with one, two or three
M/E (mixer) boards. One or two M/E systems can be upgraded with additional M/E boards.

Each M/E board provides two independent Athena scalers with universal inputs that handle
both analog and digital video sources.
The figure below illustrates a block diagram of the VP’s M/E.

The VP accepts the following inputs:
Standard component and composite analog video formats (NTSC, PAL, SECAM)
SDI video
Computer input resolutions up to 1920 x 1200 (analog or digital)
Analog HD formats including 720p, 1080I, 1080p
HD-SDI Video
Important In a widescreen configuration, a VPx cannot function in a
standalone manner, but must always work downstream of a
standard VP. Here, a VPx cannot be the first processor in an
Encore configuration.
In the special widescreen “preview” configuration, a VPx can
be used as a standalone destination that accepts DVI input
signals only — but no other input types are accepted, and no
genlock circuitry is provided.
