Ultra HD Blu-ray is a digital optical disc data storage format that supersedes Blu-ray. Ultra HD Blu-ray discs are incompatible with existing Blu-ray players. Ultra HD Blu-ray supports 4K UHD (3840x2160 resolution) video at frame rates up to 60 frames per second, encoded using High Efficiency Video Coding. 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. Ultra HD Blu-ray technology was licensed in mid 2015, and players had an expected release date of Christmas 2015. 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. Unlike conventional DVDs and Blu-rays, the new 4K format does not have region coding.
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.
