Ultra HD Forum updates Guidelines and plans watermarking API

Ultra HD Forum Tracks Over 190 UHD Services, Adds Emphasis on NGA, Releases Guidelines v2.4, and Plans First Watermarking API

FREMONT, CA — The Ultra HD Forum celebrates its fifth year of successfully bringing together broadcasters, service providers, consumer electronics manufacturers, and technology vendors to accelerate Ultra HD television deployment. The Forum has refreshed its website to better reflect its activities during this time of constrained in-person interactions. Version 2.4 of the Forum’s popular Guidelines includes more material on live OTT distribution of UHD. The Forum’s online UHD service tracker has received a significant upgrade, including new prominence given to Next Generation Audio (NGA). And the Forum plans to issue its first Watermarking API before the end of this year.

Guidelines 2.4

The Ultra HD Forum has published free Guidelines for the UHD community since 2016. The Guidelines have been a source of useful information as the television industry has launched and incrementally enhanced UHD services. The document presents a “foundation layer” of readily available, mature technologies, and an “enhancement layer,” including newer, more leading-edge technologies. Throughout five years of Guidelines development, more than 35 Forum member companies have contributed to the effort.

Version 2.4 includes many minor updates, but also some substantial additions, such as:

• Objective measurement and analysis of the quality of HDR Tone Mapping
• UHD live event distribution via OTT
• New and updated Annexes

New UHD Service Tracker

Eight years of UHD Services (Ultra HD Forum data)

Now tracking 190 commercial consumer-facing and B2B Ultra HD television service offerings, this online resource collates selected information from over three billion user subscriptions worldwide and presents it to the public on the Forum’s website. (Additional data collected about these services is available to Ultra HD Forum members only.)

According to Benjamin Schwarz, who maintains the Tracker for the Forum, “UHD service launches have continued to accelerate since 2013 when YouTube first streamed 4K publicly. Despite the COVID-related slowdown, growth this year is already at double digits again.”

Within the Forum’s Service Tracker, audio offerings can now be categorized as stereo, surround, immersive, or personalized/NGA. The Tracker also lists the audio codec(s) used by a service, whenever possible, including both “legacy” and NGA technologies.
