Professional HDMI to SDI Conversion
The ROI-HDMI is a professional-grade scan converter designed to transform HDMI and computer signals into broadcast-quality SDI outputs. It enables seamless integration of computer sources into professional video production environments without compromising image quality.
Region of Interest Control
With built-in ROI scaling technology, users can select and extract only the desired portion of the screen. This eliminates unwanted UI elements and allows precise control over what is delivered to the output feed.
