HDR video refers to a video encoded in an HDR format. Thoses HDR video have a greater bit depth, luminance and color volume than standard dynamic range (SDR) video which uses a conventional gamma curve. [22] On January 4, 2016, the Ultra HD Alliance announced their certification requirements for an HDR display.
The HDRR was tone mapped to SDR for broad compatibility with almost all displays. High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR).
SDR for HD video uses a system chromaticity (chromaticity of color primaries and white point) specified in Rec. 709 (same as sRGB). [86] SDR for SD used many different primaries, as said in BT.601, SMPTE 170M and BT.470. HDR is commonly associated to a WCG (a system chromaticity wider than BT.709).
Featuring a 144Hz refresh rate with variable refresh rate (VRR) and low latency for high-level gaming, the U8K supports all versions of HDR including HLG (Hybrid Log Gamma) to vastly improve the ...
SDR, HDR, and WDR are camera terms that refer to what type of imaging tech your device uses to capture details in over- and under-exposed lighting environments.
You're about to feel better if you've been holding back on buying a new TV. The HDMI Forum has unveiled a new specification for its namesake video connector, HDMI 2.1, and there's enough here to ...
Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.
[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.
