Dolby Vision is a high dynamic range (HDR) videoformat developed by Dolby Laboratories that is used to enhance the picturequality of 4K Ultra HD Blu-ray discs. Dolby Vision is an advanced form of HDR thatadds more brightness, contrast, and color accuracy to images, resulting in amore realistic and immersive viewing experience.
Dolby Vision works by encoding additional informationinto the video signal that is used by compatible displays to adjust thebrightness, contrast, and color of each individual frame of the video. Thisallows for more precise control over the visual elements of the video,resulting in a wider color gamut, deeper blacks, and brighter highlights. Theresult is a more lifelike and dynamic image that better represents the originalartistic intent of the content creators.
One of the advantages of Dolby Vision is that it isbackwards compatible with standard dynamic range (SDR) displays. This meansthat a Dolby Vision enabled 4K Ultra HD Blu-ray can still be enjoyed on anon-HDR capable display, with the SDR signal providing a still-impressiveviewing experience. However, to fully appreciate the benefits of Dolby Vision,a compatible TV or display is required.
In addition to its use in 4K Ultra HD Blu-ray discs,Dolby Vision is also supported by many streaming services and video-on-demand platforms, making it a widely used and recognized format for HDR content.
