Sporting a new logo and a new spec sheet, the next generation of disc-based digital media is almost ready for its summertime debut.
Today, the Blu-ray Disc Association (BDA) revealed that the Ultra HD Blu-ray specification is ready. It also unveiled a brand-new logo for the physical UHD/4K format.
Ultra HD Blu-ray offers 2160p resolution along with a slew of audio and video quality enhancements. It incorporates high dynamic range (HDR), high frame rate (HFR) and an extended color gamut that goes beyond BT.709 (the current HD standard). The format also supports immersive audio such as DTS:X and Dolby Atmos. Scott Wilkinson discussed the confirmed specs in this post filed from CES 2015.
Aside from the new logo, Scott had the complete scoop on the format months ago.
Discs will come in two capacities—66 GB dual layer and 100 GB triple layer. Maximum bitrates rates are 108 Mbps for the 66 GB disc and 128 Mbps for the 100 GB disc. The format offers up to 3840x2160 resolution (the UHD standard), and players will include HDMI 2.0 with HDCP 2.2 copy protection. The new players will handle frame rates up to 60 fps and color gamuts up to BT.2020, as well as 10-bit video.
The BDA made sure Ultra HD Blu-ray offers backward compatibility, as well as new image quality enhancing capabilities, but support for 3D at UHD resolution is notably absent.
An optional "Digital Bridge" feature is a part of the format; it offers flexible content viewing over various devices; I have not read any specifics on how it works.
New devices should start appearing soon, the BDA says it will start licensing products this summer. There's no word on when the first Ultra HD Blu-ray titles might appear. My only wish is that the players and the content launch at a reasonable cost to consumers—I don't see a new disc-based format lasting long if it's not competitively priced.
