Sky Sports launched its live HDR service for English Premier League football in August 2022, expanding to over 6000 hours of UHD HDR sport production across multiple platforms. This paper explores the end-to-end considerations for integrating live HDR while maintaining HD delivery. It details the choice of Hybrid Log-Gamma (HLG) for HDR broadcasts and how Sky uses a single UHD and HD workflow to deliver HDR and Wide Color Gamut (WCG) benefits cost-effectively. The paper examines the impact of HDR and WCG across different sports, the necessity of UHD for HDR, and the operational demands, including training for engineers. Key areas covered include the design of workflows for editing, archiving, and encoding, as well as LUT-based conversions and broadcast graphics workflows. Additionally, the paper discusses critical viewing and management of end devices in assessment environments.
