BDA Finalizes Ultra HD Blu-ray Specs

12 May, 2015 By: John Latchem

Licensing for the 4K format slated to begin in summer 2015

The Blu-ray Disc Association (BDA) May 12 announced it had completed the specification for the 4K Ultra HD Blu-ray format, with licensing scheduled to begin this summer.

The BDA also unveiled a new logo to mark UHD Blu-ray products. The Ultra-HD Blu-ray specification will enable delivery of Ultra-HD content via UHD Blu-ray to UHD TVs.

“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," said Victor Matsuda, chairman of the BDA Promotions Committee.

The completed Ultra-HD Blu-ray specification focuses on more than just increasing picture resolution to up to 3840x2160, four times the clarity of Blu-ray. It also allows for delivery of a significantly expanded color range and allows for the delivery of high dynamic range (HDR) and high frame rate content. Next-generation immersive, object-based sound formats also will be delivered via the Ultra-HD Blu-ray specification.

In addition, the optional digital bridge feature allows consumers to view their content across a wide 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.

The BDA is working with leaders in the authoring, testing, certification and replication industries to develop tools and processes needed to ensure interoperability between players and software and to facilitate the development of an ecosystem to support the hardware and title launch of Ultra-HD Blu-ray.
