Samsung announced Tuesday a new extension on its HDR10+ dynamic metadata-based high dynamic range (HDR) profile, called HDR10+ Adaptive, a profile designed to optimize TV picture quality based on a room’s ambient brightness.

The new development is said to provide new on-the-fly flexibility in adjusting the look of scene-by-scene HDR enhancements to look their best in a range of room lighting conditions. It is said to leverage the ambient light sensor built into some TV models to automatically adjust screen brightness to changing lighting conditions, thereby optimizing picture quality to a range of environments, and not just dark rooms, for which HDR systems are typically preset.

Samsung said it plans to launch the HDR10+ Adaptive system globally beginning with QLED TV products slated for 2021 and planned for formal introduction during Virtual CES 2021, beginning January 11th.

The intended benefit of HDR10+ Adaptive sounds very similar to Dolby’s Dolby Vision IQ profile that was first announced last year. That system, which is currently present in select 4K TV models from LG and others, also automatically optimizes HDR content to changing room light conditions.

Samsung pointed out that its HDR10+ Adaptive profile will work with the Ultra HD Alliance’s Filmmaker Mode, which was announced last year as a new picture mode that turns off post-processing effects like motion smoothing and video noise reduction to present film-based movies and programs as the filmmakers original intended them to appear. Samsung, LG and others began offering Filmmaker Mode in select better-performing 2020 TV models.

The new HDR10+ Adaptive feature will work with movies and programs that are graded in post production to the HDR10+ tone mapping criteria. Although not as widely available as Dolby Vision HDR movies, services including Amazon Prime and some Ultra HD Blu-ray titles are now offering HDR10+ support.

In addition, Universal Pictures Home Entertainment (UPHE) and Samsung will be extending their technology partnership to further expand the catalog of HDR10+ content available in new titles for distribution on OTT services around the world, the companies announced.

Comparatively, movies and programs graded for Dolby Vision dynamic metadata have been more prominently available on streaming services and in new 4K Ultra HD Blu-ray titles. With both Dolby Vision and HDR10+, 4K/HDR televisions that don’t offer specific support for either profile will auto-default to the baseline HDR10 that uses so-called static metadata. This keeps brightness and color grading parameters at one constant level throughout a movie, instead of adjusting to levels on a shot-by-shot basis for a more natural appearance.

Samsung continues to be the primary TV manufacturer supporting its HDR10+ profile in televisions, although gradually more companies, like Panasonic (in countries outside of the U.S.), Hisense and TCL have climbed on board as well.

Samsung’s announcement did not say if any its legacy QLED TV models will be updateable to support the HDR10+ Adaptive feature or if any other brands intend to support it this year.
