12G-SDI provides an incredible 12 gigabits per second of throughput, that’s about 8 times faster than HD-SDI, and sets a new standard for SDI connectivity! Just like 6G-SDI, it’s compatible with all of your SD, HD, and Ultra HD equipment. The increased bandwidth of 12G-SDI lets you output Ultra HD over a single cable all the way up to high frame rate 2160p60!

Optical Fiber

Lossless long distance video connections

Traditional copper cabling is bulky, expensive, and can only be used in lengths of 300’ or less for video. Fiber optic cable is readily available, cost effective, and can carry video up to an amazing 28 miles without any signal loss! If you’re in a large facility or working on location with cameras distributed in the field, Teranex standards converters can connect to them via optical fiber. Depending on whether you’re doing SD, HD, or Ultra HD determines the maximum length of your fiber run:

  • Standard Definition = 27.8 miles
  • High Definition (720p, 1080i, 1080p) = 15.5 miles
  • Ultra HD = 7.5 miles

10-Bit Quality

High precision image processing

To get the highest picture quality, video processing operations like image scaling, color correction, compositing and other effects need to be processed using 10-bit precision. That’s because when you manipulate video with 8-bit precision, each time you render or change the image, precision can be truncated back to 8-bits, which can introduce color “banding” and other unwanted artifacts. With 10-bit image processing, you get four times the color resolution, resulting in significantly higher quality images.

Embedded Audio

Up to16 channels of embedded audio on a single cable!

SDI signals can contain up to sixteen mono channels (or 8 stereo pairs) of 48kHz 20 or 24-bit audio. SDI signals with embedded audio can be run over traditional coaxial copper cable, or over optical fiber cable. That means you get perfectly synchronized, professional quality audio embedded with the video over a single cable that can be patched, routed, or distributed around your facility!

Closed Caption

Automatically preserve or convert subtitles

Closed Caption data is now mandatory in many countries for traditional broadcast distribution and, increasingly, distribution of content over the internet. Captions are usually stored as ancillary data embedded into an SDI stream. Teranex standards converters understand the different types of Closed Caption data found in SD and HD video streams, and will preserve and convert it into the proper CEA-608 or CEA-708 format for your output video.


Automatic aspect ratio and picture flags

Active Format Description (AFD) and Widescreen Signaling (WSS) are a standard set of codes that carry information about a video signal’s aspect ratio and active picture characteristics. AFD is often used in the generation of WSS and tells your display how to best present the video that it is receiving. Teranex standards converters preserve AFD and WSS information during the conversion process, so that means your screen will automatically select the correct aspect ratio for video playback.
