NDI® HD mini

HD mini is ScienceImage’s first HD, full NDI® bidirectional codec, supports up to 3G-SDI and HDMI 4K30 with SMPTE input; Accurately restores the color and the clarity of the original image. It integrates 3G SDI and HDMI 4K30 encoding technology, converts video streams into network streams, supports 1080P60 video decoding output to large screens. Widely used in programming, multi person remote video, and medical surgery teaching, providing users with excellent AV experience.

Encoding/Decoding in one key switch

Switch Full NDI® encoding and decoding with one key; Support 3G-SDI and HDMI 4K30 or below any SMPTE standard format input; Full NDI® encodes and decodes exact original image color and sharpness, low latency, broadcast-grade metrics, flexible UDP features, integrated TALLY, audio embed/unembed and call capabilities, flexible live applications and networking, enabling your team to quickly build an IP broadcast-grade studio with high efficiency and low cost.

Flexible deployment, convenient and practical

The box can be used as a Full NDI® Encoder or Decoder, flexibly deployed in the front end or display/control terminal according to different scenarios in the field; While NDI® works, it is also an SDI/HDMI Bi-Directional converter; One machine multi-purpose, reduce the system cost, to be able to respond quickly, flexible, convenient.


Support NDI® functions, the application of NDI® features and tool set, give full play to the remote advantages of NDI®, not limited by the region and network bandwidth, anytime, anywhere to build the studio you need.
