As UHD HDR becomes the default for premium live sports and entertainment, quality depends on more than capture—it depends on consistent, measurable delivery across complex conversion and QC chains. This session connects three timely challenges: interoperable, metadata-driven HDR master workflows to ensure reliable HDR/SDR conversions; new HDR-native metrics and visualization tools (including HSAM and the “Stop Waveform”) designed for modern monitoring and QC; and the rising importance of dialog intelligibility as the next audience-facing audio quality benchmark. Together, these papers offer practical methods to standardize quality and protect creative intent across today’s broadcast and streaming ecosystems.
