Mixed SDI/HDMI single keyer card

The DELTA-12G11-hmi11-e-key is a mixed interface, hardware keyer card, specially designed for critical real-time AI/AR video pipelines.

This card targets high-reliability and high-performance applications, in either SDI or HDMI environment, while providing a low-latency reliable keyed output.

Tailored for augmented reality use cases in computer-assisted surgery, robotics, and surgical navigation, the DELTA-12G11-hmi11-e-key meets all the requirements of a robust solution, including : active and passive bypass to secure the video path against a series of incidents, fanless cooling to eliminate mechanical risk linked to rotating elements, and PCIe hockey stick for better retention.

The card meets IEC 60601-1-2 EMI/ESD requirements for the certification of medical electrical devices.

DELTA-12G11-hmi11-e-key can be used in a Windows, Linux or Mac computer, as well as in ARM-based embedded platforms or dedicated medical appliances like NVidia Clara Holoscan.
