U-HUB 12G-SDI to NDI Codec

NDI® official technical background + more advanced application functions

12G-SDI and NDI HX bidirectional conversion

With simultaneous encoding and decoding, dual use in one machine

U-HUB 12G-SDI to NDI codec supports two-way conversion between 12G-SDI and NDI HX. It has the advantages of high bit rate, high image quality (4Kp60 default 250Mbps), and end-to-end ultra-low latency. The device is exquisite and compact, supporting 12G-SDI 4Kp60 video input, encoding into NDI® stream output, or decoding 4K NDI® stream, and outputting 12G-SDI 4Kp60 video.

Wide range of application scenarios

IP-based production of ultra-high-definition video programs, low-latency video projection, low-latency video transmission, video conference input and output, etc. The following is an application example video.


With dual functions of NDI® encoding + decoding, one machine with dual functions

● Plug and play, SDI to NDI®, or NDI® to 12G-SDI to the screen can be easily realized;

● Both encoding and decoding support video resolutions up to 4Kp60 (UHD), and are backward compatible with SD/HD/VESA resolutions and other special resolutions;

● YCbCr 4:2:2 NDI high-quality encoding ensures excellent picture quality, and lossless audio encoding ensures high-fidelity sound quality; ultra-low latency, end-to-end latency is less than 100ms;

● Through accurate clock and only algorithm, to ensure video frame synchronization, as well as accurate picture and audio synchronization;
