The Ultra HD Forum, the global organisation promoting the industry’s proven best practices for the delivery of immersive UHD experiences, has released a major Phase A Guidelines update.

Version 1.5 is the fifth public release and reflects another intense year of collective industry experience. Key changes from version 1.4 are:

1. Descriptions and workflow diagrams of four “real world” deployments of UHD / HDR services for marquee television events (major sports tournaments, parades, etc.).
2. Synergies between Phase A and Phase B technologies. (Phase B technologies are independent, incremental additions to the foundation of Phase A technologies.)
3. Important new standards that support Phase A workflows, including SMPTE ST 2108-1 for carriage of HDR metadata over SDI interfaces.
4. Clarification between “HDR10” and “PQ10” to ensure alignment with other new SDOs’ specifications such as SCTE’s.
5. More detail about two-step forensic watermarking methods.

Ultra HD Forum Phase A guidelines were first published in 2016, and include:

• End-to-end workflows for UHD services
• Resolutions of 1080p (with HDR) and 2160p
• HDR / WCG (PQ10, HLG10 and HDR10)
• Channel-based immersive audio
