HDR10+cite-ref-1[1] is a high dynamic range (HDR) video technology that adds dynamic metadatacite-ref-2[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.cite-ref-3[3] HDR10+ is the default variant of dynamic metadata as part of the HDMI 2.1 standard.cite-ref-4[4]

HDR10+ Adaptive is an update designed to optimize HDR10+ content according to the ambient light.cite-ref-5[5]

HDR10+ Gaming is an HDR standard optimized for gaming, providing accurate HDR gaming images with low latency, variable refresh rate (VRR) and high frame rate.

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.cite-ref-6[6]cite-ref-hdr10plus2017april2017samsung-7-0[7]cite-ref-hdr10plus2017april2017zdnet-8-0[8]cite-ref-hdr10plus2017april2017forbes-9-0[9] The technology is standardized and defined in SMPTE ST 2094-40.cite-ref-10[10]cite-ref-smpte2094dynamicmetadatajanuary2017-11-0[11]cite-ref-hdr10plus2017april2017tvtechnology-12-0[12]cite-ref-hdr10plus2017april2017samsung-7-1[7]cite-ref-hdr10plus2017april2017zdnet-8-1[8]cite-ref-hdr10plus2017april2017forbes-9-1[9] HDR10+ is an open standard and is royalty-free; it is supported by a growing list of post-production software and tools.cite-ref-hdr10plus2017april2017samsung-7-2[7]cite-ref-hdr10plus2017april2017zdnet-8-2[8]cite-ref-hdr10plus2017april2017forbes-9-2[9] HDR10+ specifications are not publicly available.

On 28 August 2017, Samsung, Panasonic, and 20th Century Fox created the HDR10+ Technologies LLCcite-ref-hdr10-llc-14-0[14] to promote the HDR10+ standard.cite-ref-hdr10standardaugust2017flatpanelshd-15-0[15] HDR10+ video started being offered by Amazon Video on 13 December 2017.cite-ref-hdr10amazondecember2017forbes-16-0[16] On 5 January 2018, Warner Bros. announced their support for the HDR10+ standard.cite-ref-hdr10january2018forbes-17-0[17] On 6 January 2018, Panasonic announced Ultra HD Blu-ray players with support for HDR10+.cite-ref-panasonichdr10january2018forbes-18-0[18] On 4 April 2019, Universal Pictures Home Entertainment announced a technology collaboration with Samsung Electronics to release new titles mastered with HDR10+.cite-ref-samsunguniversalagreement-19-0[19] It is considered to have most of the advantages of Dolby Vision over HDR10, as well as being royalty free.

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.cite-ref-20[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.cite-ref-21[21]

HDR10+ and Dolby Vision do not use the same dynamic metadata.

• 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,cite-ref-22[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 Metadatacite-ref-23[23]

• Metadata (optional): MaxCLL, MaxFALLcite-ref-24[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 compatibility is achieved via the WebM container.cite-ref-25[25]

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+ SEIcite-ref-26[26])

• displaying HDR10+ content on a capable display (e.g. HDMI interfaces with HDR10+ VSIF) and mobile devices cite-ref-27[27]

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:

1. Identifying scene cuts, and

2. Performing an image analysis on each scene or frame to derive statistics

HDR10+ metadata is interchanged through a low complexity JSON-structured text file,cite-ref-28[28] which is then parsed and injected into video files.

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+cite-ref-29[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.

HDR10+ metadata can co-exist with HDR10 static metadata that makes HDR10+ content backward compatiblecite-ref-30[30] with non-HDR10+ TVs. HDR10+ metadata is ignored by devices that do not support the format and video is played back in HDR10.

HDR10+ Technologies, LLCcite-ref-31[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.
