Serial Digital Interface (SDI) is a digital video interface that provides a range of advantages for transmitting video and audio. This long-lived standard has been around nearly 30 years and is still as relevant as ever, keeping up with the changing demands of today’s technology. Now, SDI has come out with its most powerful iteration: 12G-SDI. Let’s take a look at all of the details.
12G-SDI brings the SDI standard to the next level with improved resolution, frame rate and color over a single cable. Capable of 12 Gbps speeds, it delivers four times the bandwidth of HD and is perfectly suited for the 4K 60p format. This makes it ideal for live broadcasting, studio sets and venues where it’s important for a cable to maintain a strong signal while also being easy to connect and fairly lightweight. 12G-SDI is also expected to expand into fiber to increase its distance and bandwidth capabilities up to 10km and open up opportunities for 12G technology throughout broadcast and production facilities.
Though this standard has been under development since 2012, it has not yet been ratified by the governing body of standards, the Society of Motion Picture and Television Engineers (SMPTE). Thus, not all manufacturers have begun making products to support 12G-SDI. But those that are being made are delivering customers with cables and connectors that are simple to connect with better image and signal, and without extra weight or cost. Even without ratification, 12G-SDI is a viable standard offering real solutions for today’s video and audio demands.
