    OG-ROI-DVI - Overview

    AJA's OG-ROI-DVI is an openGear DVI to 3G-SDI Scan Converter. This versatile unit features incredible region-of-interest image scaling as well as aspect and frame rate conversion, OG-ROI-DVI fulfills the growing need to properly incorporate computer signals into the video world without sacrificing budget or space.

    ROI, or Region of Interest, allows you to eliminate extra interface clutter and menu bars and extract only the portion of the computer screen you want.

    OG-ROI-DVI 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 exactly 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.

    It is also possible to expand output options and create a large, synchronized video wall display. The workflow diagram shows 9 OG-ROI-HDMI utilized in a rackframe to produce a video wall of 9 SDI monitors. Control over each OG-ROI-HDMI is provided via ethernet to the DashBoard. Each computer source is connected to an OG-ROI-HDMI input with the region of interest output via SDI. Simple controls and connectivity for the OG-ROI-HDMI can be used to create sophisticated and complex video wall presentations.

    OG-ROI-DVI accepts 2-channel analog audio from 2x 3-pin terminal blocks connectors. The audio source 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.
