Live HDR Workflow

Many Broadcasters and Production houses started transition from HD to UHD (Ultra-HD, 4k and 8k). One of the biggest challenges in this transition is use of High Dynamic Range (HDR) for live production applications. Use of HDR technology is very important as it can provide better adoption of cameras to rapidly changing lighting condition. High Dynamic Range increases the difference between black and white beyond the contrast range of conventional television. That means water can glisten, stars can twinkle, and sunlight can be golden, all whilst maintaining detail in the shadows. This paper will explain one of the techniques how to simultaneously produce 4K-HDR and SDR in live events and bring HDR content to consumer UHD TV sets. Explanation of Color Gamut and Electro-Optical Transfer Function will help to better understand different HDR standards and processing that needs to be applied in the whole chain.
