AJA OG-ROI-DVI openGear DVI to 3G-SDI Scan Converter Card

The AJA OG-ROI-DVI openGear DVI to 3G-SDI Scan Converter Card is an openGear scan converter designed to integrate computer/DVI sources into a 3G-SDI baseband video workflow, providing proper scaling and timing control. It includes Region of Interest image scaling, plus aspect and frame rate conversion, so PC-style signals can be incorporated into SDI systems without wasting rack space.

Highlights

• DVI to 3G-SDI conversion with DVI loop-through
• Region of Interest scaling for precise framing and clean conversions
• Scan conversion from computer resolutions to video resolutions
• Up, down, and cross conversion with aspect ratio and frame rate conversion
• Remote configuration via Ross Dashboard over Ethernet

Quick Specs & Uses

• Input format range: accepts DVI up to 1920 x 1200 at 60 Hz (VGA minimum 640 x 480)
• SDI output: 3G-SDI (SMPTE-259/292/424), 1x BNC
• Supported video families: SD, HD, and 3G formats (see format lists in specs)
• EDID emulation to stabilize computer output behavior
• Audio: supports up to 8 channels embedded; 2-channel analog audio I/O via 3-pin terminal blocks

Why It Helps

Computer signals don’t naturally behave like broadcast video. OG-ROI-DVI handles the tough parts in the rack: scaling only the region you actually need, matching aspect ratios cleanly, and converting frame rates so the output lands as a stable SDI signal that plays nicely with switchers, routers, and recorders.

Key Technical Notes

• Geometry tools: image H/V flip and 90-degree rotation
• Interlace/progressive handling: conversion between deinterlaced and progressive signals
• Loss of input behavior: selectable Black, Freeze, or Mute
• Genlock/reference options: Reference Input, DVI Input, or Free Run (supports tri-level sync and color black refs)
• System requirements: two openGear slots per card; rear I/O card included; hot-swappable

Frame & Facility Fit

• Compatible frames: OG-X-FR, OG-3-FR, and DFR-8321 openGear frames
• Power: openGear frame compatible, 8.0 W max per card
• Environment: operating 0 to 40 C (32 to 104 F); storage -40 to 60 C (-40 to 140 F)
