    "abstract": "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. Graphics insertion is extensively used, presenting scores and analytics. These graphics must remain stable to provide a consistent appearance throughout the conversions. Today, diverse tone mapping and inverse tone mapping technologies are proposed to industry, each with the promise to create premium HDR content while maintaining the quality of SDR versions. Look Up Tables (LUTs) are the chief conversion technique used today, but constrain the capabilities of HDR and/or compromise the SDR look. Further, their static nature exposes content to artifacts emerging from changing conditions during live capture (e.g., sunset, passing clouds, shadows). While dynamic techniques accommodate such changes, a problem emerging is that none of the different LUT solutions nor dynamic solutions are fully interoperable: Each produces content with different properties, requiring different conversions to satisfy the critical requirement of delivering a seamless final content. This paper presents a generic solution, based on metadata, that resolves the compatibility issue. We present an implementation, a dynamic solution, implementing this proposal and providing tools based on dynamic metadata generation that ensures viewers enjoy the highest HDR video quality with no compromise of the SDR stream. By leveraging an image-based adaptation having already-acknowledged benefits of dynamic conversion, this solution introduces a constraint to allow stable graphics management: a specific Static Diffuse White, which ensures compatibility with existing static workflows while offering resolution to their shortcomings and paves the way for industry to transition smoothly from static to dynamic techniques and ensure delivery of premium HDR and SDR content.",
