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 ...
Audio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. [18] Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For example, if the ceiling of a device ...
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 term dynamic range may mean: Dynamic range, dynamic range is a term used frequently in numerous fields to describe the ratio between the smallest and largest possible values of a changeable quantity. High-dynamic-range imaging, the intention of HDRI is to represent the wide range of intensity levels found in real scenes.
HDR10 Media Profile, more commonly known as HDR10, is an open high-dynamic-range video (HDR) standard announced on August 27, 2015, by the Consumer Electronics Association. [1] It is the most widespread HDR format. [2] HDR10 is not backward compatible with SDR. It includes HDR static metadata but not dynamic metadata.
High dynamic range, a general term describing dynamic range across multiple fields; High-dynamic-range video, a technology related to HDR displays and formats such as HDR10, Dolby Vision, HDR10+, and others. High-dynamic-range rendering, techniques in computer-generated imagery; Multi-exposure HDR capture, a technique for capturing high dynamic ...
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. [3] HDR10+ is the default variant of dynamic metadata as part of the HDMI 2.1 standard. [4]
