Overview  ROI-DP

AJA’s ROI-DP DisplayPort to SDI with ROI scaling allows high quality conversion of computer DisplayPort outputs to baseband video over SDI at an economical price. The ROI-DP offers an extensive audio functionality, incredible image scaling as well as aspect and frame rate conversion.

Region of Interest
ROI Mini-Converter can be connected via USB to a computer running the free Mini-Config application. This allows the users to 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 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. It also provides a simple menu controls that let you choose the proper output for any situation. The output will be mirrored to both the 3G-SDI and HDMI outputs for simultaneous delivery to multiple displays or continuing signal paths.


ROI uses 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.

Audio Support

ROI support 2-channel audio from the 3.5mm analog audio input or embedded 8-channel audio from a DisplayPort input. The audio source and routing can be selected manually in the Mini-Config software and is embedded in the SDI output. This allows computer audio to be embedded within the SDI signal for simple, synchronized routing.
