Onyx Product Guide

Multi Channel Option

Multl-Channel Option (MCO)

The Multi-Channel Option provides multiple output channels for applications such as visual simulation, entertainment and virtual reality. Tightly coupled to the graphics subsystem, the Multi-Channel Option converts digital information stored in the graphics frame buffer into a variety of multiple analog video signals--or channels--which can then be displayed on additional monitors or projection devices.

With up to six independent channels per RealityEngine2 graphics pipeline, the MultiChannel Option is a cost-effective method of delivering several output channels - all from a single system.

Multi-Channel Option (MCO) Board

MCO Board - allows users to drive multiple channels from a single system and drag/move images from one display
Architected for Low Transport Delay - less than 0.5 milliseconds
Up to Six Channels of output per MCO Board
Three MCO boards in an Onyx with three RealityEngine2 Pipelines - can drive up to 18 channels of output offering a low cost per channel solution for visual simulation, VR, and location-based entertainment application.

Supports a Wide Range of Formats and Timings
