New HDR10+ Feature Optimizes Picture for Ambient Light
January 5, 2021
HDR10+ Technologies, a consortium led by Panasonic Corp. and Samsung Electronics, has announced the specifications for a new feature called HDR10+ Adaptive, designed to optimize HDR10+ content for a more consistent viewing experience in various environments.
HDR10+ is an enhanced version of HDR10 that leverages dynamic metadata to maximize the black level and peak brightness of every scene and frame on displays.
HDR (high dynamic range) reference material is typically produced in dark rooms at mastering houses or production studios, while content viewing conditions at home range from well-lit family rooms to totally dark home theaters. As a result, ambient and stray light can affect the amount of image detail and contrast the human eye perceives, according to the group.
HDR10+ Adaptive, using HDR10+ dynamic metadata, in conjunction with real-time ambient-light information, allows compatible displays to automatically optimize brightness levels, on a scene-by-scene basis, to ensure that the creator’s intent is fully realized, under a variety of viewing conditions, according to the group.

It is expected that televisions with HDR10+ Adaptive capability will be introduced this year by companies such as Panasonic, Samsung and others, the group reported.
In addition to a number of Blu-ray Discs available that utilize HDR10+ technology, including the Academy Award-winning Best Picture Parasite, distributed by Universal Pictures Home Entertainment, the group announced that a number of companies have recently released products that support HDR10+, including:
- Qualcomm, which announced that their latest flagship smartphone processor (Snapdragon 888) now incorporates HDR10+ as part of its 5G Mobile Platform;
- Realtek Semiconductor Corp., which debuted a series of HDR10+ compatible SOC’s (System On Chips) for use in 4K UHD set-top boxes from Android TV and RDK;
- Denon and Marantz, which have introduced 13 HDR10+ compatible AV receivers to date;
- and Magenta TV in Germany and Watcha in Korea, which now deliver HDR10+ programming in their respective regions.
