Ultra HD Blu-ray (marketed as 4K Ultra HD) is a digital optical disc data storage format that supersedes Blu-ray.[2] Ultra HD Blu-ray discs are incompatible with existing standard Blu-ray players (though in most cases, a traditional Blu-ray and digital copy has been packaged with the Ultra HD Blu-ray discs).[1] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive 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. It is supported on Microsoft's Xbox One X[3] as well as the S model[4], as well as Sony's upcoming PlayStation 5[5][6] video game consoles.

To differentiate Ultra HD Blu-ray titles on store shelves, the format uses a black opaque or slightly transparent keep case packaging format.

Specifications[edit]

The specification allows for three disc capacities, each with its own data rate: 50 GB at 82 Mbit/s, 66 GB at 108 Mbit/s, and 100 GB at 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 and AACS 2. In addition, AACS 2.1 is used on certain titles (Stand by Me, Fury, The Patriot, Zombieland).[citation needed]

On May 12, 2015, the Blu-ray Disc Association revealed completed specifications and the official Ultra HD Blu-ray logo.[7] Unlike conventional DVDs and Blu-rays, the new 4K format does not have region coding.[8]

On February 14, 2016, the BDA released Ultra HD Blu-ray with mandatory support for HDR10 Media Profile video and optional support for Dolby Vision.[9][10]

As of January 23, 2018, the BDA spec v3.2 also includes optional support for HDR10+ and Philips/Technicolor's SL-HDR2.[11]

Initial titles[edit]

The first Ultra HD Blu-ray Discs were officially released from four studios on February 14, 2016:[12]
