In the last article in our three-part series, we explored the advantages of SDI and how 12G-SDI is applied in broadcast facilities. In this article, we investigate applications where SDI excels.
Reporters for WAFF-TV, the NBC affiliate in Huntsville, Alabama, have seen their share of weather disasters and learned to adapt to working from home for short periods of time. It goes with covering the territory. The current pandemic situation, however, is another story all together. It’s a story that, with each week, brings mental fatigue but also a can-do spirit to help the local community get through the crisis.
High dynamic range and wide color gamut combined with 4K resolution and progressive frame rates have catapulted broadcast television to new levels of immersive experience for the viewer.

Recent international events have overtaken normality causing us to take an even closer look at how we make television. Physical isolation is greatly accelerating our interest in Remote Production, REMI and At-Home working, and this is more important now than it ever has been.
The dominant reason for the adoption of color difference working is that it allows the color difference signals to be reduced in bandwidth without obvious loss of picture quality. Only the luma signal needs to be retained at full bandwidth. There are various ways in which that can be done.
In the last article in this series we looked at how SDI has developed over the years to reach an incredible 47.52Gbits/sec for quad-link 12G. In this article, we dig deeper and uncover the technology enabling SDI and its advantages.
