AJA ROI-SDI 3G-SDI to HDMI/3G-SDI Scan Converter
Best professional tool for precise SDI signal scaling and region extraction.
The AJA ROI-SDI is a versatile scan converter designed to precisely extract a Region of Interest (ROI) from 3G-SDI sources. It simultaneously mirrors the processed signal to both 3G-SDI and HDMI outputs, simplifying your workflow. This device offers comprehensive scaling options, including up, down, and cross-conversion, along with frame rate and aspect ratio adjustments. It supports 8-channel embedded audio input and output, plus a 2-channel analog RCA audio output. A dedicated 3G-SDI loop-through ensures signal integrity, and configuration is made easy via USB with the Mini-Config software.
