AJA ROI DVI/HDMI to SDI with ROI scaling 


AJA's ROI Mini-Converter allows exceptionally high quality conversion of computer DVI and HDMI outputs to baseband video over SDI at an affordable price and a very portable size. With incredible image scaling, extensive aspect ratio and frame rate conversion, and audio functionality ROI fulfills the growing need to properly incorporate computer signals into the video world without sacrificing budget or space.



Key Features

Region of Interest

The free MiniConfig application lets you interactively select a Region of Interest from the incoming DVI or HDMI signal and control how that region is scaled to the output resolution using AJA’s high quality scaling algorithms for the cleanest picture quality possible. Eliminate extra interface clutter and menu bars and extract only the portion of the image you want.


Take full control of aspect ratio and frame rate conversion with on-screen controls in the MiniConfig software that show you exactly what your source and output will look like and what formats are coming in and going out. Simple menu controls let you quickly choose the proper output for any situation.


ROI utilizes a DVI loop through, allowing it to be placed in-line so you still have a connection to an external DVI or HDMI monitor while extracting to SDI. The reference input ensures the SDI signal out of ROI is locked for use throughout a production or facility.


ROI accepts 2-channel audio from the 3.5mm analog audio input or embedded 8-channel audio from an HDMI input. The audio source and routing can be selected in the MiniConfig software and is embedded in the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.
