Abstract: Deploying separate high dynamic range (HDR) and standard dynamic range (SDR) production facilities to cover the same event simultaneously can be economically prohibitive. In this case study, we present a new method for creating both ultrahigh-definition (UHD) HDR and HD SDR streams from a single UHD HDR production workflow, developed through a series of real-world UHD HDR production trials in 2018 and 2019, concluding with the 2019 Football Association Challenge Cup (FA Cup), a major U.K. sporting event. We describe the findings from those trials and the lessons learned and include descriptions of what worked well and what worked less well. The workflow solution presented allows for the integration of both HDR camera sources and SDR camera sources (e.g., super slow-motion and specialist cameras), prerecorded or archive SDR content and SDR graphics into a single HDR production environment. It can exploit the backward-compatible nature of the hybrid log-gamma (HLG) HDR solution and recent advances in color volume management. We show how a production’s two outputs, HDR and SDR, can be made using current SDR shading/racking monitoring, with only a single HDR vision guarantee monitor.

bio
Simon Thompson has worked at British Broadcasting Corporation (BBC) Research & Development (R&D), London, U.K., for 17 years, researching workflows for high dynamic range (HDR) video production recently and has worked on programs including the Fédération Internationale de Football Association (FIFA) World Cup, Wimbledon, and The Royal Wedding. His former projects include radio frequency (RF) spectrum management, RF transmission design, additional services for digital video broadcasting (DVB) broadcasts and Official Journal of the European Union (OJEU) procurements for cameras and the new broadcasting house newsroom and video workflow optimization. He is currently a member of the European Broadcasting Union Video Systems Group, International Telecommunication Union Research Group 24, World Wide Web Consortium Media Group, and the Digital Television Group’s Production Technology Group. He also serves on the SMPTE Board of Editors.

Andrew Cotton is a principal technologist within BBC R&D’s Broadcast & Connected Systems Section. He has a background in video compression and image processing. He and his team are responsible for maintaining the technical integrity of the BBC’s acquisition, production, playout, and Internet Protocol (IP) distribution systems. Most recently, their work has focused on HDR TV, as he is one of the developers of the HLG HDR system. He joined BBC Research in 1987 after graduating from the University of Oxford, Oxford, U.K., with a BA degree in engineering science. He spent seven years in industry working for a leading broadcast equipment manufacturer but returned to the BBC in 2002. He won the IBC 2015 Conference Prize with colleague Tim Borer for their paper “A Display Independent High Dynamic Range Television System.”
