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.

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.

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.
