    "abstract": "Live HDR television production has been slow to gain acceptance because it has often been found to compromise the quality of a standard dynamic range (SDR) BT.709 signal derived from the HDR. Whilst parallel SDR/HDR production workflows are possible, they greatly increase the expense and complexity of a production. This paper describes how “scene-light” format conversions, as opposed to the more usual “display-light” conversions, allow SDR and HDR cameras to be intermixed in an HDR production, and an SDR BT.709 output to be derived from an Hybrid Log-Gamma (HLG) HDR production workflow without compromising the quality of the SDR BT.709 signal. — The paper illustrates how these technologies have been deployed in four major international events over the summer of 2018; thereby proving their suitability for live HDR production and paving the way for simpler live HDR production workflows in the future.",
