HDR-SDR conversion: Live HDR Single Master Production Conversion Interoperability Challenges

Live production workflows, particularly those for sports, employ complex pipelines to deliver HD, UHD, SDR, and HDR video streams. Because content originates as HDR or SDR, effective and flexible conversions are required between formats. A growing number of live sport events are today produced in a HDR single-master workflow, where conversions are still required at production stage and HDR to SDR down-conversion is necessary at distribution side. An emerging challenge is about ensuring operational knowledge to secure proper use of conversion tools and to improve interoperability between different solutions such as static and dynamic conversions. This paper discusses the challenge and evaluation consensus. A generic solution is proposed, based on metadata to improve workflows efficiency while providing premium HDR and SDR contents.
