Reference excerpt

HDR10+ is a high dynamic range (HDR) video technology introduced by Samsung Electronics Co., Ltd, 20th Century Fox Home Entertainment and Panasonic Corporation as an open, royalty-free dynamic metadata platform for High Dynamic Range (HDR) video. Designed to enhance image quality by applying scene-by-scene tone mapping, HDR10+ aims to deliver improved brightness, contrast, and color accuracy across compatible displays. The platform addresses limitations of static HDR formats by enabling dynamic adjustment of visual parameters, thereby more faithfully reproducing filmmakers’ creative intent. Licensing of HDR10+ was scheduled to commence in January 2018, with a nominal administrative fee and broad availability to content producers, hardware manufacturers, and system-on-chip vendors. The partnership emphasized flexibility and scalability, positioning HDR10+ as a future-ready standard for next-generation home entertainment systems.

Description HDR10+, also known as HDR10 Plus, was announced on 20 April 2017, by Samsung and Amazon Video. HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to the full range of PQ code values (10,000 nits maximum brightness) on a scene-by-scene or frame-by-frame basis. The technology is standardized and defined in SMPTE ST 2094-40. HDR10+ is an open standard and is royalty-free; it is supported by a growing list of post-production software and tools. HDR10+ specifications are not publicly available. A certification and logo program for HDR10+ device manufacturers is available with an annual administration fee for certain adopter categories and no per-unit royalty. Authorized test centers conduct certification testing for HDR10+ devices. On 28 August 2017, Samsung, Panasonic, and 20th Century Fox created the HDR10+ Technologies LLC to promote the HDR10+ standard. HDR10+ video started being offered by Amazon Video on 13 December 2017. On 5 January 2018, Warner Bros. announced their support for the HDR10+ standard. On 6 January 2018, Panasonic announced Ultra HD Blu-ray players with support for HDR10+. On 4 April 2019, Universal Pictures Home Entertainment announced a technology collaboration with Samsung Electronics to release new titles mastered with HDR10+. HDR10+ signals the dynamic range and scene characteristics on a scene-by-scene or even frame-by-frame basis. The display device then uses the dynamic metadata to apply an appropriate tone map through the process of dynamic tone mapping. Dynamic tone mapping differs from static tone mapping by applying a different tone curve from scene-to-scene rather than use a single tone curve for an entire video.

Technical details

HDR10+ content profile EOTF: SMPTE ST 2084 (PQ) Chroma subsampling: 4:2:0 (for compressed video sources), 4:2:2 and 4:4:4 Resolution: Agnostic (2K/4K/8K, etc.) Bit depth: 10-bit or more (up to 16-bit) per color channel Color primaries: ITU-R BT.2020 Maximum linearized pixel value: 10,000 cd/m2 for each color R/G/B (content) Metadata (required): Mastering Display Color Volume Metadata Metadata (optional): MaxCLL, MaxFALL HDR10+ supports the full range PQ up to 10,000 cd/m2. Being resolution agnostic, metadata needs to be created only once and can be applied to any target resolution. HDR10+ content can be encoded using video encoding technologies including HEVC (implemented with VSEI) and AV1, VP9 compatibility is achieved via the WebM container.

Workflow and ecosystem

HDR10+ utilizes an HDR10 master file within existing HDR post-production and distribution workflows. The HDR10+ ecosystem is used within current systems by,

storing HDR10+ metadata in JSON files embedding HDR10+ metadata into HDR10 encoded content distribution through digital stream (e.g. streaming with HDR10+ SEI) displaying HDR10+ content on a capable display (e.g. HDMI interfaces with HDR10+ VSIF) and mobile devices

Metadata generation

For offline and video-on-demand (VOD) (e.g. ultra-high-definition Blu-ray, over-the-top (OTT), multi-channel video programming distributor (MVPD)), HDR10+ metadata may be created during the post-production mastering process or during transcoding/encoding for distribution back-ends by HDR10+ content generation tools in two steps:

Identifying scene cuts, and Performing an image analysis on each scene or frame to derive statistics HDR10+ metadata is interchanged through a low complexity JSON-structured text file, which is then parsed and injected into video files.

Live encoding

Live use cases are possible by delivering HDR10+ metadata in every frame. HEVC encoders generate and inject metadata on live content and mobile phones record video and create HDR10+ metadata in real-time during recording. Live encoding is detailed in the Live Encoder Workflow diagram and real time broadcast operations are supported at the point of transmission enabling a metadata-less broadcast operation.

Compatibility

HDR10+ metadata can co-exist with HDR10 static metadata that makes HDR10+ content backward compatible with non-HDR10+ TVs. HDR10+ metadata is ignored by devices that do not support the format and video is played back in HDR10.

Worked examples

Example 1 — a first encounter with HDR10+

Start with the simplest possible case. Write down what HDR10+ claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to HDR10+ before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about HDR10+ ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of HDR10+

In research: HDR10+ appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses HDR10+ in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: HDR10+ is common in secondary-school and first-year university syllabi. It links to neighbouring topics High dynamic range, Ultra-high-definition television, so understanding it makes those chapters shorter.
In everyday life: Look for HDR10+ outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
