Viewing audiences are continually driving broadcasters to deliver improved video formats to further enhance the immersive experience. It didn’t seem so long ago that HD was lauded as the best format ever. Not only did we end up quadrupling the number of pixels and frame rates to deliver 12G-SDI, but we also mixed them with high dynamic range and wide color gamut.

SDI has been the mainstay of broadcast infrastructures since its adoption in the early 1990’s. It may look like engineers are defying the laws of physics, but with incredible design skills, they have been constantly improving SDI so it can now deliver quad-link 12G-SDI capable of transporting 8Kp video with fabulously low latency.

This Core Insights presents cutting edge information to help engineers, technologists and anybody interested in building and operating broadcast facilities to understand the benefits of using SDI, especially as we progress to 12G-SDI for HDR, WCG and 4K/8K video. This Core Insights contains;

1 – Developing 12G-SDI

An overview of SDI, where it came from and where we are now. The relevant standards are described along with some of the key advantages of using 12G-SDI.

2 – 12G-SDI Technology

Discussion of where 12G-SDI will excel in the overall broadcast infrastructure including HDR and WCG.

3 – Applications for 12G-SDI

Description of some of the specific applications where 12G-SDI is used and why. Backwards compatibility and future proofing are discussed.

Download this Core Insight today to better understand 12G-SDI and the benefits 12G-SDI has to offer.
