Ultra HD Blu-ray is a digital optical disc data storage format that supersedes Blu-ray.[2] Ultra HD Blu-ray discs are incompatible with existing Blu-ray players.[1] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 resolution) video at frame rates up to 60 frames per second,[2] encoded using High Efficiency Video Coding.[2] The discs support both high dynamic range by increasing the color depth to 10-bit per color and a greater color gamut than supported by conventional Blu-ray video by using the Rec. 2020 color space.
Specifications
The 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.[2] Ultra HD Blu-ray technology was licensed in mid 2015, and players had an expected release date of Christmas 2015.[2] Ultra HD Blu-ray uses a new revision of AACS DRM, AACS 2.
On May 12, 2015, the Blu-ray Disc Association revealed completed specifications and the official Ultra HD Blu-ray logo.[3] Unlike conventional DVDs and Blu-rays, the new 4K format does not have region coding.[4]
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.[5][6]
Initial titles
The first Ultra HD 4K Blu-ray Discs were officially released from four studios on March 1, 2016.[7] These were Sony (six titles: The Amazing Spider-Man 2, Salt, Hancock, Chappie, Pineapple Express, and The Smurfs 2),[8] Lionsgate (four titles: Sicario, The Last Witch Hunter, The Expendables 3, and Ender's Game),[9] Warner Bros.
