Specifications for the Ultra HD Blu-ray format have been formalized according to the Blu-ray Disc Association. The new discs will support 4K resolution and both high dynamic range and high frame rate content.
Current Blu-ray delivers around 35% of the colors that the human eye can make out, Ultra HD Blu-ray will be capable of 75% of discernible colors. Licensing for the new disc is expected to begin this summer and the first players are expected out before the year’s end.
One key bit of importance – UHD Blu-ray Disc players will also play current Blu-ray Discs, but current players will NOT play the new discs.
