## Long description

AJA ROI-SDI is a compact serial converter, repeater and isolator for SDI signals, designed to condition, isolate and extend SDI connections in broadcast and professional AV environments. The unit measures 146.4 × 102.1 × 22.9 mm and accepts 100–240 V input voltage via the supplied universal power supply. ROI-SDI extracts a customizable Region of Interest (ROI) from a 3G-SDI input and provides mirrored outputs on 3G-SDI and HDMI while maintaining audio embedding and reference locking for consistent signal routing.
Advantages
ROI-SDI provides high-quality ROI extraction and image scaling using AJA’s scaling algorithms, enabling precise reframing, rotation and aspect-ratio control without significant loss of image integrity. Its 3G-SDI loop-through and genlock/reference input preserve synchronization in complex signal chains, and the included universal power supply with international plugs and locking power connector ensures reliable operation in studio and field setups. Audio handling supports 8-channel embedded audio with selectable routing and a stereo RCA monitoring output.
Suitable for
Broadcast studios and OB vans where SDI signal conditioning and isolation are required
Live events and pro AV installations needing ROI extraction and aspect ratio conversion
Signal distribution chains that require loop-through and genlock/reference locking
Camera rigs or monitor setups where compact, portable conversion to HDMI and SDI is needed
Key specifications
Input: 3G-SDI (with embedded 8-channel audio)
Outputs: mirrored 3G-SDI and HDMI (with embedded audio) plus stereo RCA monitoring output
Functions: Region of Interest extraction, scaling and aspect ratio conversion
Loop-through: 3G-SDI loop-through for inline monitoring
Reference: Genlock/reference input for signal locking
Power: universal power supply included, supports mains 100–240 V input; device uses DC 5–18 V via provided adapter
Dimensions: 146.4 × 102.1 × 22.9 mm
Form factor: compact, portable converter suitable for rack, monitor or camera-mounting integration
How to use
Connect the 3G-SDI source to the ROI-SDI input and connect the 3G-SDI loop-through to a monitor or downstream device if inline monitoring is required. Use the genlock/reference input when synchronisation with facility signals is necessary. Connect HDMI and 3G-SDI outputs to target displays or recorders. Attach the supplied universal power supply and verify the locking connector is secure. For interactive ROI selection, connect the unit to a computer via USB and run AJA’s Mini-Config application to define the Region of Interest, set scaling and aspect ratio conversion, and configure audio routing.
Usage recommendations
For stable operation, ensure the reference input is used when integrating ROI-SDI into multi-device production environments. When extracting a Region of Interest, preview the result in Mini-Config and choose scaling options that preserve critical image detail. Use the stereo RCA output for quick audio checks and verify embedded audio mapping in the software before final distribution. For portable or battery-powered setups, use the optional P-TAP cable with a compatible battery and confirm the locking power connector is seated to prevent accidental disconnection.
