USER’S MANUAL
1 KXI-DVI-Bridge Graphic-to-HD/SD Video Interface
This document describes the installation and specification of the KXI-DVI-Bridge. Details of the integration
with Kaleido are available in the Kaleido user documentation. Please see “Compatibility” on page 15 for a list
of Kaleido models that can be used with the KXI-DVI-Bridge.
1.1 Introduction
Miranda’s KXI-DVI-Bridge performs live extraction of computer graphics to generate an SMPTE 292M
compliant link meant for the Kaleido multi-image processor. Each unit provides two independent DVI-to-HD-
SDI conversion processes.
A firmware upgrade now allows the KXI-DVI-Bridge to also perform conversions of DVI signals from a
Kaleido to HD-SDI formats.
1.2 Basic Features
Originally designed as a Kaleido input device, the KXI-DVI-Bridge converts a DVI signal to HD-SDI at a
specific resolution and frame rate (1920x1080p @ 29.97 Hz)
1
. This allows a Kaleido to accept inputs from a
PC at larger VGA resolutions, up to 1600x1200 2 , over a standard HD-SDI signal, without sacrificing quality.
The input resolution from the PC can be XGA, SXGA, WXGA, WSXGA+ or UXGA, but must have a 60 Hz
refresh rate.
Basic KXI-DVI-Bridge Features:
• Dual Channel – pixel-to-pixel extraction on each discrete channel
• Two HD-SDI outputs per channel
• Auto-sensing
DVI input
• One DVI loop output per channel
• Auto-sensing of input format within the Kaleido’s HD-SDI input
• Platform/OS
independent
• Extend reach of DVI signal by using SDI wiring
• Ideal for static content such as the view of an automation system’s run-down list.
1 The reduced frame rate of 29.97 Hz may not result in a smooth playback of video or animations generated by a computer.
2 The 1600x1200 input resolution is supported on the Kaleido-X, but not on the Kaleido-Alto/Quad/Quad-Dual/K2.
