AJA ROI DVI to SDI Mini-Converter
Key Features
  • DVI to SDI Conversion
  • DVI Loop Through for Monitoring
  • HDMI Adapter Supported on Input & Loop
  • Region of Interest Scaling
AJA's ROI DVI to SDI Mini-Converter converts a DVI signal to an SDI output, enabling you to use computer signals in digital video workflows. On an included MiniConfig software application compatible with Macs and PCs, you'll be able to select a Region of Interest from the input signal and assign how the region is scaled to the output. You can assign image scaling and extensive aspect ratio and frame rate conversions. The Converter syncs up to the MiniConfig application via a USB cable connection to the host computer. A USB cable and a universal power supply are also included.

AJA ROI-DVI Overview

AJA's ROI DVI to SDI Mini-Converter converts a DVI signal to an SDI output, enabling you to use computer signals in digital video workflows. On an included MiniConfig software application compatible with Macs and PCs, you'll be able to select a Region of Interest from the input signal and assign how the region is scaled to the output. You can assign image scaling and extensive aspect ratio and frame rate conversions. The Converter syncs up to the MiniConfig application via a USB cable connection to the host computer. A USB cable and a universal power supply are also included.

A DVI loop through will allow you to monitor the input locally, and a reference input will let you genlock the SDI output. Both the DVI input and loop through support optional DVI-to-HDMI adapters, so you can convert HDMI to SDI and/or monitor your input on an HDMI display.

A 3.5mm TRS input supports 2 channels of analog audio, the SDI output supports 8 embedded channels at 24-bit, and the DVI input supports 8-channel, 24-bit HDMI embedded audio if you use a DVI-to-HDMI adapter.

Key Features
  • DVI to SDI conversion
  • Region of Interest scaling
  • DVI loop through
  • DVI-to-HDMI adapter supported on input and loop through
  • Audio embedding
  • Aspect ratio conversion
  • Genlock input
  • Conversions are configured via included MiniConfig software
  • Uses 5-18VDC power (universal power supply included)
Region of Interest
In an included MiniConfig software application, you'll be able to select a Region of Interest in an incoming DVI or HDMI signal and control how that region is scaled to the output resolution. This selection will let you eliminate extra interface clutter and menu bars and extract only the portion of the image you want.
Conversion
On-screen controls in the included MiniConfig software will let you manage aspect ratio and frame rate conversion. MiniConfig will show you exactly what your source and output will look like and what formats are coming in and going out.
Connectivity
The Converter features a DVI loop through enabling a connection to an external DVI monitor (or HDMI monitor via a DVI-to-HDMI adapter) while converting to SDI. A Reference input ensures the SDI output is genlocked for use throughout a production or facility.
Audio
The Converter accepts 2-channel audio from a 3.5mm analog audio input or embedded 8-channel audio from an HDMI input (DVI-to-HDMI adapter). The audio source and routing can be selected in the included MiniConfig software and is embedded in the SDI output, allowing computer audio to be embedded within the SDI signal for easy, synchronized routing.

AJA ROI-DVI Reviews

Stable, long-term performance in a medical setting

By Kim

I've got four of these converters for use in converting medical monitoring sources to 3G SDI, one of which I've installed permanently in one of our OR control rooms for fluoroscopy. It has been in place for more than six years now, never unplugged (control room personnel need their monitors to function every day, all day, without interruption). Every couple of months I have to get the SDI signal from it and every time it's flawless. I have a few friends around the country who do similar work as me and they use these converters for their reliability. They're worth every penny to have peace of mind.

Fantastic!

I've been using 4 of these for over a year now to convert a DVI signal from a computer to SDI that I send out to projectors. I use them every week for hours on end. They're simple plug and play and require no settings to be changed. If you need something that is MUST work, this is for you.
