AJA OG-ROI-HDMI openGear HDMI to 3G-SDI Scan Converter

The AJA OG-ROI-HDMI openGear HDMI to 3G-SDI Scan Converter is an openGear scan converter designed to convert computer and HDMI sources into clean, properly timed 3G-SDI baseband video. It combines Region of Interest (ROI) image scaling with aspect ratio and frame rate conversion, allowing HDMI and computer signals to integrate into SDI workflows without wasting rack space or budget.

Highlights

• HDMI to 3G-SDI conversion with HDMI loop-through
• Computer-to-video scan conversion for broadcast-compatible outputs
• Region of Interest scaling for precise cropping and framing
• Up, down, and cross conversion with aspect and frame rate conversion
• Remote configuration via Ross Dashboard over Ethernet

Quick Specs & Uses

• Input: 1x HDMI (with up to 8-channel embedded audio)
• Outputs: 1x 3G-SDI BNC (SMPTE-259/292/424), 1x HDMI loop-through
• Max input formats: HDMI and computer signals up to 1920 x 1200 at 60 Hz
• Supported video families: SD, HD, and 3G formats
• Audio: HDMI embedded audio or 2-channel balanced analog audio input

Why It Helps

HDMI and computer signals rarely match broadcast timing or framing requirements. OG-ROI-HDMI handles the conversion inside the rack, allowing you to crop the active portion of the image, match aspect ratios, and convert frame rates so the output behaves like standard SDI video that can be routed, monitored, or recorded reliably.

Key Technical Notes

• Geometry controls: image horizontal/vertical flip and 90-degree rotation
• Scan type handling: conversion between progressive and interlaced signals
• Loss-of-input handling: selectable Black, Freeze, or Mute
• Genlock options: Reference Input, HDMI Input, or Free Run
• EDID emulation to stabilize HDMI and computer source behavior

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
• Form factor: openGear front card with rear I/O; two slots required
• Warranty: five-year warranty
• Environmental: operating 0 to 40 C (32 to 104 F)
