In November 2016, support for HDR video was added which can be encoded with hybrid log–gamma (HLG) or perceptual quantizer (PQ). [43] HDR video can be encoded with the Rec. 2020 color space. [44] YouTube videos are available in a range of quality levels. Viewers only indirectly influence the video quality.
[54] [55] In 2016, HDR conversion of SDR video was released to market as Samsung's HDR+ (in LCD TV sets) [56] and Technicolor SA's HDR Intelligent Tone Management. [ 57 ] As of 2018, high-end consumer-grade HDR displays can achieve 1,000 cd/m 2 of luminance, at least for a short duration or over a small portion of the screen, compared to 250 ...
Online video platforms allow users to upload, share videos or live stream their own videos to the Internet. These can either be for the general public to watch, or particular users on a shared network. The most popular video hosting website is YouTube, 2 billion active until October 2020 and the most extensive catalog of online videos. [1]
[7] [8] ITU specifies the use of PQ or HLG as transfer functions for HDR-TV. [7] PQ is the basis of HDR video formats (such as Dolby Vision, [2] [9] HDR10 [10] and HDR10+ [11]) and is also used for HDR still picture formats. [12] [13] PQ is not backward compatible with the BT.1886 EOTF (i.e. the gamma curve of SDR), while HLG is compatible.
High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual.. The term is often used in discussing the dynamic ranges of images, videos, audio or radio.
The ITU announced Rec. 2100 which defines two HDR transfer functions which are HLG and PQ. [5] [30] Digital UK published their 2017 specification for Freeview Play which includes support for HDR using HLG. [16] The Digital Video Broadcasting (DVB) Steering Board approved UHD-1 Phase 2 with an HDR solution that supports HLG and PQ.
Images, audio and video files must be uploaded into Wikipedia using the "Upload file" link on the left-hand navigation bar. Only logged in users can upload files. Once a file is uploaded, other pages can include or link to the file. Uploaded files are given the "File:" prefix by the system, and each one has an image description page.
FP16 blending can be used as a faster way to render HDR in video games. Shader Model 4.0 is a feature of DirectX 10, which has been released with Windows Vista. Shader Model 4.0 allows 128-bit HDR rendering, as opposed to 64-bit HDR in Shader Model 3.0 (although this is theoretically possible under Shader Model 3.0).
