Dieses Zeichen ist ein Other Symbol und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Das Schriftzeichen ist auch bekannt als high dynamic range.
Das Zeichen ist keine Zusammensetzung. Seine Weite in ostasiatischen Texten wird vom Kontext bestimmt. Es kann weit oder schmal sein. In bidirektionalem Text wird es von links nach rechts geschrieben. Bei einem Richtungswechsel wird es nicht gespiegelt. Wenn seine ostasiatische Weite „schmal“ ist, bildet U+1F1A7 mit ähnlichen Zeichen ein Wort, das in sich Zeilenumbrüche verbietet. Andernfalls erlaubt es Zeilenumbrüche um sich herum, außer in einigen numerischen Kontexten.
Die Wikipedia hat die folgende Information zu diesem Codepunkt:
High-dynamic-range television (HDR-TV) is a technology that uses high dynamic range (HDR) to improve the quality of display signals. It is contrasted with the retroactively-named standard dynamic range (SDR). HDR changes the way the luminance and colors of videos and images are represented in the signal, and allows brighter and more detailed highlight representation, darker and more detailed shadows, and more intense colors.
HDR allows compatible displays to receive a higher-quality image source. It does not improve a display's intrinsic properties (brightness, contrast, and color capabilities). Not all HDR displays have the same capabilities, and HDR content will look different depending on the display used, and the standards specify the required conversion depending on display capabilities.
HDR-TV is a part of HDR imaging, an end-to-end process of increasing the dynamic range of images and videos from their capture and creation to their storage, distribution and display. Often, HDR is used with wide color gamut (WCG) technology. WCG increases the gamut and number of distinct colors available. HDR increases the range of luminance available for each color. HDR and WCG are separable but complementary technologies. Standards-compliant HDR display also has WCG capabilities, as mandated by Rec. 2100 and other common HDR specifications.
The use of HDR in television sets began in the late 2010s. By 2020, most high-end and mid-range TVs supported HDR, and some budget models did as well. HDR-TVs are now the standard for most new televisions.
There are a number of different HDR formats, including HDR10, HDR10+, Dolby Vision, and HLG. HDR10 is the most common format, and is supported by all HDR-TVs. Dolby Vision is a more advanced format that offers some additional features, such as scene-by-scene mastering. HDR10+ is a newer format that is similar to Dolby Vision, but is royalty-free. HLG is a broadcast HDR format that is used by some TV broadcasters.
