The Ultra HD Forum has published version 3.0 of its guidelines as the organisation aims to make them more accessible for users.
The guidelines have been restructured into a series of nine shorter “Rainbow Books”, each concentrating on a specific aspect of Ultra HD: definitions, technology, production, distribution, and real-world experiences.
This new format allows for more frequent updates in crucial areas of Ultra HD that are still evolving, said the Forum.
The updated guidelines aim to offer greater clarity on HDR in the production book (Blue) and include updated linear metadata for immersive audio. The Black book defines additional terms, such as Single-Master HDR/SDR Production.
The Forum has also published an updated Ultra HD Service Tracker, which now features details on nearly 250 customer-facing Ultra HD services, showcasing significant growth in US-based ATSC 3.0 services in recent quarters.
More details on the new “Rainbow Books” and Service Tracker can be found at the Ultra HD Forum’s website.
