AJA HDMI to SDI with ROI scaling

Watch this video to learn how to configure and control your ROI with AJA’s free Mini-Config control software.

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.

You’re able to easily create highly effective and engaging displays by using additional ROI-HDMI mini-converters. By utilizing three ROI-HDMI mini-converters you can feed three display monitors side by side, each rotated to portrait mode. By using the HDMI pass through of the ROI-HDMI, the HDMI routed image is in sync, with each ROI-HDMI providing the necessary region of interest output via SDI. The result is a visually exciting and creative way to feed display content.

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.

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.

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 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.
