- Abstract
- Live production, particularly for sports, increasingly employs high dynamic range (HDR) single-master workflows to deliver high-definition (HD), ultrahigh-definition (UHD), standard dynamic range (SDR), and HDR, with graphics insertion extensively used for presenting scores and analytic overlays. The workflows are complex: As content originates as HDR or SDR, conversions between formats are required, and graphics must consistently appear. Static Look-Up Tables (LUTs) are the chief conversion technique used today, though dynamic conversions are available, too. The problem is that each of these conversions produces content with different properties, and none are fully interoperable: Each requires different conversions to deliver a consistent final product. This paper presents a metadata-based solution that resolves the compatibility issue. We present an implementation of this proposal and provide tools that ensure viewers enjoy the highest HDR video quality without compromising the SDR stream. While leveraging the already-acknowledged benefits of dynamic conversion, a new constraint, a specific Static Diffuse White, allows stable graphics management and provides compatibility with existing static LUT workflows, offering resolution to their shortcomings and paving the way for a smooth transition from static to dynamic conversions and single-master delivery of premium HDR and SDR content.
