The Encore Video Processor is a compact chassis that provides Encore’s input and output
circuitry. Two models are available:
• The “standard” Video Processor (VP) is a full-featured unit that includes all input,
output, genlock and link circuitry.
• The VPx is an economical VP with a reduced set of inputs (DVI only). The VPx is
ideal for widescreen configurations, and for special widescreen “preview”
configurations. VPx includes all output and link circuitry, but no genlock circuitry,
and only a small subset of the standard VP’s input circuitry.
• 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.
