Blu-ray 4K specs published

The Blu-ray Disc Association (BDA) has completed its specification for its Ultra-HD devices. Consumers should be able to buy UHD discs and players during Q4 this year.

“For years, Blu-ray Disc has set the standard for high definition picture and audio quality in the home. Ultra-HD Blu-ray will do the same for UHD home entertainment,” said Victor Matsuda, chair, BDA Promotions Committee.  “The technical capabilities of Blu-ray Disc, in particular its significant storage capacity and high data transfer rates, will enable the delivery of an unparalleled, consistent and repeatable UHD experience.”

The completed Ultra-HD Blu-ray specification addresses a range of factors, beyond simply increasing resolution, that will significantly enhance the home entertainment experience for consumers. In addition to delivering content in up-to 3840×2160 resolution, the Ultra-HD Blu-ray format enables delivery of a significantly expanded colour range and allows for the delivery of high dynamic range (HDR) and high frame rate content. Next-generation immersive, object-based sound formats will also be delivered via the Ultra-HD Blu-ray specification.  Additionally, with the optional digital bridge feature, the specification enhances the value of content ownership by embracing the notion that a content purchase can enable the consumer to view their content across the range of in-home and mobile devices.

The specification also mandates all new Ultra-HD Blu-ray players be capable of playing back current Blu-ray Discs, giving consumers access to the vast library of more than 10,000 titles currently available on Blu-ray Disc.

Licensing of Ultra-HD Blu-ray is scheduled to begin this Summer.  The BDA is working closely with industry leaders in the authoring, testing, certification and replication industries to develop  the tools and process needed to ensure interoperability between players and software and to facilitate the development of a robust ecosystem to support the hardware and title launch of Ultra HD Blu-ray.
