AJA ROI-DVI DVI/HDMI to 3G-SDI Mini-Converter with ROI Scaling
The AJA ROI-DVI DVI/HDMI to 3G-SDI Mini-Converter facilitates the seamless integration of computer-generated video signals into professional broadcast and production environments. This high-performance hardware solution converts DVI or HDMI inputs into 3G-SDI outputs, offering advanced scaling, frame rate conversion, and aspect ratio management within a compact, portable form factor.
The AJA ROI-DVI provides exceptional control over computer signal processing through its dedicated Region of Interest (ROI) functionality. This feature allows users to select a specific portion of the DVI input signal and scale it to the desired SDI output resolution. The hardware-based scaling engine ensures high-quality image reproduction without the artifacts typically associated with software-based cropping, making it an essential tool for live broadcasts, presentations, and digital signage.
This mini-converter supports a wide range of VESA resolutions and frame rates, ensuring compatibility with various computer sources and professional video standards. The unit includes a DVI-D loop-through output, which maintains a local monitor connection while simultaneously delivering the converted signal to the SDI infrastructure. This dual-output capability eliminates the need for external distribution amplifiers in most monitoring setups.
The AJA ROI-DVI manages audio embedding with precision to ensure perfectly synchronized delivery across the production chain. The device supports 2-channel analog audio input via a 3.5mm jack or 8-channel embedded HDMI audio. Users can map these audio sources directly into the 3G-SDI output stream, providing a complete video and audio solution for professional workflows.
Configuration of the AJA ROI-DVI occurs through the AJA Mini-Config software via a USB connection. This intuitive interface provides a visual representation of the input and output signals, allowing for precise adjustments to cropping, scaling, and signal parameters. The software-driven approach ensures that the converter remains versatile and easily adaptable to changing production needs.
The AJA ROI-DVI is engineered for diverse professional applications, including:
