HDR10 is an … [97], On September 9, 2016, Google announced Android TV 7.0, which supports Dolby Vision, HDR10, and HLG. AHdrMetadata_smpte2086 #include SMPTE ST 2086 "Mastering Display Color Volume" static metadata. [19][20] In 2016, HDR conversion of SDR video was released to market as Samsung's HDR+ (in LCD TV sets)[21] and Technicolor SA's HDR Intelligent Tone Management. [57], On August 28, 2017, Samsung, Panasonic, and 20th Century Fox created the HDR10+ Alliance[58] to promote the HDR10+ standard.

[91], Rec. 1 Matrix coefficients: BT. [52][53][54] A certification and logo program for HDR10+ device manufacturers will be made available with an annual administration fee and no per unit royalty. [91] The HDR reconstruction metadata can be added either to HEVC or AVC using a supplemental enhancement information (SEI) message. • Color primaries and white point should be set to BT.709 (the format of the incoming video). 1 HDR10+ updates HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 4,000 nits maximum brightness on a scene-by-scene or frame-by-frame basis and supports up to 10bit colour depth and 8K resolution. HDR video is also needed in applications that demand high accuracy for capturing temporal aspects of changes in the scene. High dynamic range video: from acquisition, to display and applications, Dufaux, Frédéric, Patrick Le Callet, Rafal Mantiuk, and Marta Mrak, eds, Academic Press, 2016. [51][52][53][54] This function is based on Samsung application SMPTE ST 2094-40 Application #4. [26][27][28] HDMI 2.1 was officially announced on January 4, 2017, and added support for Dynamic HDR, which is dynamic metadata that supports changes scene-by-scene or frame-by-frame. In 1991, the first commercial video camera using consumer-grade sensors and cameras was introduced that performed real-time capturing of multiple images with different exposures, and producing an HDR video image, by Hymatom, licensee of Cornuéjols. L While technically "HDR" refers strictly to the ratio between the maximum and minimum luminance, the term "HDR video" is commonly understood to imply wide color gamut as well. This standard specifies the metadata items to specify the color volume (the color primaries, white point, and luminance range) of the display that was used in mastering video content. [92] UHD Phase A defines HDR as having a dynamic range of at least 13 stops (213=8192:1) and WCG as a color gamut that is wider than Rec. SMPTE ST 2086, 2018 Edition, April 9, 2018 - Mastering Display Color Volume Metadata Supporting High Luminance and Wide Color Gamut Images This standard specifies the metadata items to specify the color volume (the color primaries, white point, and luminance range) of the display that was used in mastering video content.

[31], The perceptual quantizer (PQ),[32][33] published by SMPTE as SMPTE ST 2084, is a transfer function that allows for the display of high dynamic range (HDR) video with a luminance level of up to 10,000 cd/m2 and can be used with the Rec. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve. c [4] To accommodate this, HDR encoding standards allow for a higher maximum luminance and use at least a 10-bit dynamic range (color depth, compared to 8-bit for non-professional and 10-bit for professional SDR video[5]) in order to maintain precision across this extended range. On June 24, 2015, Amazon Video was the first streaming service to offer HDR video using HDR10 Media Profile video. [22], As of 2018, high-end consumer-grade HDR displays can achieve 1,000 cd/m2 of luminance, at least for a short duration or over a small portion of the screen, compared to 250-300 cd/m2 for a typical SDR display.

[96], On July 6, 2016, the International Telecommunication Union (ITU) announced Rec. Modern movies have often been filmed with cameras featuring a higher dynamic range, and legacy movies can be converted even if manual intervention would be needed for some frames (as when black-and-white films are converted to color)[citation needed]. This is important in monitoring of some industrial processes such as welding, in predictive driver assistance systems in automotive industry, in surveillance video systems, and other applications. o VESA defines a set of HDR levels, all of them must support HDR10, but do not need to have 10-bit displays for some of them. MaxCLL = Maximum Content Light Level - the value in nits of the brightest pixel in the entire clip. UHD Phase A are guidelines from the Ultra HD Forum for distribution of SDR and HDR content using Full HD 1080p and 4K UHD resolutions. Also in 1991, Cornuéjols introduced the principle of non linear image accumulation HDR+ to increase the camera sensitivity:[8] in low-light environments, several successive images are accumulated, increasing the signal-to-noise ratio. [39][40], On July 29, 2016, SKY Perfect JSAT Group announced that on October 4, they will start the world's first 4K HDR broadcasts using HLG. MPEG2, MPEG-4 AVC single, dual, quad up to 1080i60/1080p30 or UHD/4k, HEVC/Vp9 display, HDR10 SMPTE ST 2084, ST 2086 “Blu-Ray” standard and HLG support Also, special effects, especially those that mix real and synthetic footage, require both HDR shooting and rendering[citation needed]. On September 12, 2017, Apple announced the Apple TV 4K with support for HDR10 and Dolby Vision, and that the iTunes Store would sell and rent 4K HDR content. [102], Video having a dynamic range greater than that of standard-dynamic-range video. [60] On January 5, 2018, Warner Bros. announced their support for the HDR10+ standard. m You should use this information to configure your app's HDR tonemapping and gamut mapping. [29][30], The Society of Motion Picture and Television Engineers (SMPTE) created a standard for dynamic metadata: SMPTE ST 2094 or Dynamic Metadata for Color Volume Transform (DMCVT). ) [39][80][81] HLG is supported by HDMI 2.0b, HEVC, VP9, and H.264/MPEG-4 AVC. [55][31][56][52][53][54] HDR10+ is an open standard and is royalty-free; it is supported by Colorfront's Transkoder and MulticoreWare's x265. HDR video can be also considered to speed image acquisition in applications that need a large number of static HDR images are, for example in image-based methods in computer graphics.

SMPTE ST 2086 "Mastering Display Color Volume Metadata Supporting High Luminance and Wide Color Gamut Images" describes static data such as MaxFALL (Maximum Frame Average Light Level) and MaxCLL (Maximum Content Light Level). [24] The previous HDMI 2.0 version already supported the Rec. [74] HLG is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays, consumes additional bandwidth, and may also become out-of-sync or damaged in transmission. What else hides in PS4? Say what? SL-HDR1 allows for HDR rendering on HDR devices and SDR rendering on SDR devices using a single layer video stream. [62] On April 4, 2019, Universal Pictures Home Entertainment announced a technology collaboration with Samsung Electronics to release new titles mastered with HDR10+.

[63], Dolby Vision is an HDR format from Dolby Laboratories that can be optionally supported by Ultra HD Blu-ray discs and streaming video services. 2100, which uses HLG or PQ as transfer functions with a Rec. HDR10 uses SMPTE ST-2086 "Mastering Display Color Volume" static metadata to send color calibration data of the mastering display, as well as MaxFALL (Maximum Frame Average Light Level) and MaxCLL (Maximum Content Light Level) static values. [83][98], On September 26, 2016, Roku announced that the Roku Premiere+ and Roku Ultra will support HDR using HDR10. [77][78][79], HLG is defined in ATSC 3.0, Digital Video Broadcasting (DVB) UHD-1 Phase 2, and International Telecommunication Union (ITU) Rec. [66][67][68] Dolby Vision includes the Perceptual Quantizer (SMPTE ST 2084) electro-optical transfer function, up to 8K resolution, and a wide-gamut color space (ITU-R Rec.

Samsung has proposed a change to the SMPTE ST.2086 base standard HDR10 by adding dynamic metadata so it can perform much like Dolby Vision. represent HDR (PQ, standardized as SMPTE ST 2084), information about the display the content was mastered on (SMPTE ST 2086), and dynamic information about the content (SMPTE ST 2094). Later, in the early 2000s, several scholarly research efforts used consumer-grade sensors and cameras. Colorfront is a world-class software development company in the field of high performance digital processing technologies for the motion picture industry.
