Region of Interest

Eliminate extra interface clutter and menu bars and extract only the portion of the computer screen you want.

OG-ROI-HDMI is fully compatible with the free Ross DashBoard application, offering interactive selection of a Region of Interest from the incoming computer signal. You 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, image rotation and frame rate conversion with on-screen controls in the DashBoard software that shows you what your source and output will look like, including the formats that are coming in and the choices you have made for the signal going out.



OG-ROI-HDMI 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 OG-ROI-HDMI is locked for use throughout a production or facility.



OG-ROI-HDMI accepts 2-channel analog audio from the 2x 3-pin terminal blocks connectors or embedded 8-channel audio from an HDMI input. The audio source and routing can be selected in the DashBoard software and is embedded into the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.
