BT2084

BT2084 is a color space and transfer function developed by the British Broadcasting Corporation (BBC) and the European Broadcasting Union (EBU). It is designed to improve the accuracy and efficiency of color representation in high dynamic range (HDR) video. The BT2084 transfer function is a perceptual transfer function, meaning it is designed to match the human eye's response to light, which allows for more efficient use of bits in digital video. This is particularly useful in HDR video, where the range of luminance levels is much greater than in standard dynamic range (SDR) video. The BT2084 transfer function is used in conjunction with the BT2100 color space, which is also designed for HDR video. Together, these standards are intended to provide a more accurate and efficient representation of color in HDR video, which can lead to improved image quality and a more immersive viewing experience. BT2084 is widely adopted in the broadcasting industry and is supported by many HDR-compatible devices and platforms.
