Dolby Vision is a proprietary HDR video format that combines PQ encoding with dynamic, scene-by-scene metadata to tone map content for each display.
HDR10 is the open high dynamic range video format that combines PQ encoding, Rec. 2020 color, 10-bit depth and static metadata for HDR delivery.
HDR10+ is an HDR video format that adds dynamic, scene-by-scene metadata to HDR10 so displays can tone map each shot to their own brightness limits.
HLG, or Hybrid Log-Gamma, is a backward-compatible HDR video transfer function built for live broadcast that needs no dynamic metadata.
Peak luminance in HDR video is the highest brightness, in nits, that a display can produce or that content is mastered to reach in its brightest…
PQ, the perceptual quantizer, is the absolute HDR transfer function that maps video code values to brightness levels of up to 10,000 nits.
SDR, or standard dynamic range, is the conventional video format mastered for about 100 nits peak brightness with Rec. 709 color and a gamma transfer curve.
Tone mapping in HDR video compresses mastered brightness and color into the range a particular display can reproduce while preserving intent.
