The Ultra HD Forum will publish its first unified Guidelines document defining industry best practices for the introduction of technologies to facilitate ultra-high-definition (UHD) viewing experiences for both Static Metadata and Dynamic Metadata based HDR formats. The currently deployed static metadata HDR systems, most notably HDR 10 and HLG, are now referred to as ‘foundation’ UHD technologies, by the UHD Forum. It now also guides "the ‘enhancements’ that are backward compatible so they will add value to setups that support them, but still, look and sound great on foundation equipment”. In other words Dynamic metadata, and potentially higher brightness for highlights, over 1000 or 4000 nits the limits in some of the current systems. Although the Forum never gets specific in its announcement.
The Forum says it acknowledges 8K development as a promising future technology and plans to work on its inclusion within future versions of the Guidelines. UHDF president, Thierry Fautier said; “8K is not at the same state of maturity as 4K, and not widely deployable without further development and advances in the ecosystem. Our immediate interest is in 4K and HD resolution-based services and technologies, but the Forum continues to monitor the development of 8K video as it may relate to television production and distribution, including leveraging 8K production and display technologies within a 4K distribution system".
At the forum's NAB booth member companies will demonstrate how foundation HDR technology and dynamic metadata coexist and work to improve content reproduction on enabled displays. They will show the effect of HDR-to-SDR content switching on TVs and STBs.
Another demo pod presents UHD content from a wide variety of sources, including HDR → SDR → HDR conversions and 8K production for 4K distribution.
The European Broadcasting Union (EBU) will present essential findings on HDR and its relative impact across different screen resolutions. The effect of resolution and frame rate on HDR Content will be shown at the show in a demo comparing HDR content in HD and 4K, and at Standard and High Frame Rates.
