AJA ROI-DVI DVI/HDMI to SDI converter with ROI scaling

AJA’s ROI-SDI Scan Converter allows exceptionally high quality conversion and extraction of a Region of Interest (ROI) from a 3G-SDI input to 3G-SDI and HDMI mirrored outputs at an affordable price in a very portable form factor. With incredible image scaling, extensive aspect ratio conversion and audio functionality, ROI-SDI fulfills the growing need to customize video signals for a range of display and SDI workflow needs without sacrificing budget or space.

Region of Interest

Rotate source signals, customize a portion of an image or reframe the source image to extend the creative options for what’s been captured in camera.

Connecting a ROI-SDI Mini-Converter via USB to a computer running the free Mini-Config application lets you interactively select a Region of Interest from the original 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.

ROI Video Wall Workflow

It is also possible to expand output options and create a large, synchronized video wall display. In this workflow diagram you can see a HD video source in the Ki Pro Ultra 12G is being fed directly to a KUMO 3232 router. The KUMO 3232 can pass the same,  synchronized signal to each of the nine ROI-HDMI's. The individual Region of Interest is output via SDI to the nine video monitors. Immense flexibility can be achieved with ease, with the same solution being scalable to up to 25 monitors as a 5 x 5 video wall. To go larger simply use the KUMO 6464 and create walls of up to 64 screens in an 8 x 8 video wall, all from a single HD source.

Conversion

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. Simple menu controls let you quickly 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.

Connectivity

ROI-SDI utilizes a direct 3G-SDI loop through, allowing it to be placed in-line so you still have a connection to an external monitor while extracting to both 3G-SDI and HDMI. The reference input ensures the 3G-SDI signal out of ROI is locked for use throughout a production or facility.

Audio

ROI-SDI accepts 8-channel embedded audio from an 3G-SDI input. The audio source and routing can be selected in the Mini-Config software and is embedded in the 3G-SDI and HDMI outputs. ROI-SDI also features a stereo RCA output for simple monitoring needs.

Universal Power Supply

All AJA Mini-Converters ship with a universal power supply that includes international plug connections for use around the world.

Compact and Portable

AJA Mini-Converters are small enough to fit behind a monitor, in the back of a rack, or directly on a camera rig. A locking power connector can't accidentally pull loose and an optional P-TAP power cable allows for battery power in remote locations.
