Broadcasters are increasingly adopting IP infrastructure to enhance live sports coverage with HDR video and immersive audio. The publication of ST 2110-41 (Fast Metadata Framework) has streamlined real-time IP-based metadata workflows, supporting Dolby Vision and Dolby Atmos in live linear services. Ateme, Dolby, and Jünger Audio are leveraging ST 2110-based systems to enable end-to-end metadata communication, driving Dolby Vision, Atmos, and AC-4 distribution. ST 2110-41 facilitates the transmission of HDR video and Next Generation Audio (NGA) metadata through S-ADM (serialized Audio Definition Model) from live sources to encoders, automating workflows for ATSC 1.0/DVB and advanced ATSC 3.0/DVB-T2 use cases. France TV will use this during the Olympics 2024, and major European broadcasters will soon offer UHD Dolby Vision and Atmos services. In North America, ATSC 3.0 services will also benefit. This integration ensures precise HDR video and customizable audio experiences, simplifies UHD signal flow, and enhances scalability.
Next Generation Audio and High Dynamic Range are an essential part of immersive and accessible Live Sports experience like the one delivered for the Paris Olympics Real-time IP based metadata delivered over ST 2110-41 allow to dynamically drive NGA and HDR workflows End-to-end processing chain is now functional and deployed at scale
