HDR10+
![](https://upload.wikimedia.org/wikipedia/en/thumb/c/cc/HDR10%2B_%28logo%29.svg/220px-HDR10%2B_%28logo%29.svg.png)
HDR10+[1] is a high dynamic range (HDR) video technology that adds dynamic metadata[2] to HDR10 source files. The dynamic metadata are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way based on the content creator's intentions.
HDR10+ is an alternative to Dolby Vision, which also uses dynamic metadata.[3] HDR10+ is the default variant of dynamic metadata as part of the HDMI 2.1 standard.[4]
HDR10+ Adaptive is an update designed to optimize HDR10+ content according to the ambient light.[5]
Description
[edit]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.[6][7][8][9] The technology is standardized and defined in SMPTE ST 2094-40.[10][11][12][7][8][9] HDR10+ is an open standard [disputed (for: "open" describing something not publicly available) – discuss] and is royalty-free; it is supported by a growing list of post-production software and tools.[7][8][9] 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.[13] Authorized test centers conduct certification testing for HDR10+ devices.[13]
On 28 August 2017, Samsung, Panasonic, and 20th Century Fox created the HDR10+ Technologies LLC[14] to promote the HDR10+ standard.[15] HDR10+ video started being offered by Amazon Video on 13 December 2017.[16] On 5 January 2018, Warner Bros. announced their support for the HDR10+ standard.[17] On 6 January 2018, Panasonic announced Ultra HD Blu-ray players with support for HDR10+.[18] On 4 April 2019, Universal Pictures Home Entertainment announced a technology collaboration with Samsung Electronics to release new titles mastered with HDR10+.[19] It is considered[by whom?] to have most of the advantages of Dolby Vision over HDR10, as well as being royalty free.[citation needed]
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.[20] 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.[21]
HDR10+ and Dolby Vision do not use the same dynamic metadata.
Technical details
[edit]HDR10+ content profile
[edit]- 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,[22] 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[23]
- Metadata (optional): MaxCLL, MaxFALL[24]
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 compatability is achieved via the WebM container.[25]
Workflow and ecosystem
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/7/79/HDR10%2B_OTT_Workflow_Example.png/220px-HDR10%2B_OTT_Workflow_Example.png)
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[26])
- displaying HDR10+ content on a capable display (e.g. HDMI interfaces with HDR10+ VSIF) and mobile devices [27]
Metadata generation
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/8/8d/HDR10Plus_Metadata_Workflow_2.jpg/220px-HDR10Plus_Metadata_Workflow_2.jpg)
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,[28] which is then parsed and injected into video files.
Live encoding
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/f/f4/Live_Encoder_Workflow.png/220px-Live_Encoder_Workflow.png)
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+[29] 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
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/3/33/HDR10%2B_Backward_Compatibility.png/220px-HDR10%2B_Backward_Compatibility.png)
HDR10+ metadata can co-exist with HDR10 static metadata that makes HDR10+ content backward compatible[30] with non-HDR10+ TVs. HDR10+ metadata is ignored by devices that do not support the format and video is played back in HDR10.
Administration
[edit]HDR10+ Technologies, LLC[31] administers the license and certification program for products that want to adopt HDR10+. HDR10+ Technologies, LLC provides the technical specifications, test specifications, and certified logo.
