Ultra HD Blu-ray is a digital data storage format. It supersedes Blu-ray.[citation needed] Ultra-HD Blu-ray supports 4K UHD (3840x2160 resolution) video at frame rates up to 60 frames per second.[1] The standard encodes videos under the High Efficiency Video Coding standard.[1] 4K Blu-ray Discs support both high dynamic range by increasing the color depth to 10-bit per color and a greater color gamut by using the Rec. 2020 color space using HEVC. The 4K-Blu-ray specification allows for three disc sizes, each with their own data rate: 50 GB with 82 Mbit/s, 66 GB with 108 Mbit/s, and 100 GB with 128 Mbit/s.[1] 4K Blu-ray Disc technology will be licensed in mid 2015, and 4K Blu-ray Disc players have an expected release date of Christmas 2015.[1]
On May 12, 2015, the Blu-ray Disc Association revealed completed specifications and the official Ultra HD Blu-ray logo.[2] Unlike conventional DVDs and Blu-rays, the new 4K format does not have region coding.[3]
On March 1, 2016, the BDA released Ultra HD Blu-ray with mandatory support for HDR10 Media Profile video and optional support for Dolby Vision.[4][5] The first Ultra HD 4K Blu-ray Discs were officially released from four studios on March 1, 2016.[6] These were Sony (six titles: The Amazing Spider-Man 2, Salt, Hancock, Chappie, Pineapple Express, and The Smurfs 2),[7] Lionsgate (four titles: Sicario, The Last Witch Hunter, The Expendables 3, and Ender's Game),[8] Warner Bros. (four titles: Mad Max: Fury Road, The Lego Movie, Pan, and San Andreas),[9] and 20th Century Fox (ten titles: The Martian, Kingsman: The Secret Service, Exodus: Gods and Kings, X-Men: Days of Future Past, Maze Runner: The Scorch Trials, The Maze Runner, Wild, Agent 47, Fantastic Four, and Life of Pi).[10]
