AJA Video Systems ROI-DVI Mini Converter
DVI/HDMI to SDI with Region of Interest Scaling
AJA's ROI Mini-Converter allows exceptionally high quality conversion of computer DVI and HDMI outputs to baseband video over SDI . 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.
AJA's ROI family of Mini-Converter allows exceptionally high quality conversion of computer 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.
Region of Interest
Eliminate extra interface clutter and menu bars and extract only the portion of the computer screen you want.
Connecting a ROI Mini-Converter via USB to a computer running the free Mini-Config application lets you interactively select a Region of Interest from the incoming computer signal and have full control over how that region is scaled to the output resolution using AJA’s high quality scaling algorithms for the cleanest picture quality possible.
Take full control of aspect ratio and frame rate conversion with on-screen controls in the Mini-Config 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 direct loop through, allowing it to be placed in-line so you still have a connection to an external 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 Mini-Config software and is embedded in the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.
