The Blu-ray Disc Association has revealed further details of the forthcoming 4K Blu-ray disc format, to be called Ultra HD Blu-ray.

Back in September last year the Blu-ray Disc Association (BDA) announced that 4K Blu-ray discs and hardware would be available by Christmas 2015.

And at CES 2015 Panasonic revealed a prototype of its first 4K Blu-ray player with HDR compatibility (see picture below).

Now the BDA has confirmed further details of the new 4K Blu-ray format, according to the Hollywood Reporter: it will be called Ultra HD Blu-ray, and will be applied to discs that can handle resolution up to 3840 x 2160 and frame rates up to 60fps (frames-per-second).

Ultra HD Blu-ray will also have a wider colour range than standard Blu-rays, 10-bit colour depth and HDR (High Dynamic Range) will also be a key part of the spec. Disc sizes will range from 66GB (dual layer) up to 100GB (triple layer).

As for Ultra HD Blu-ray players, they will use the HEVC (H.265) codec adopted by the likes of Netflix for streaming 4K, and will also play standard Blu-ray, DVD and CD discs.

A final spec for Ultra HD Blu-ray is expected to be released by the BDA in mid-2015.
