Sonic Solutions announced today that its US Patent 6,944,621 for dynamic content revision has been evaluated as essential to the Blu-ray Disc specification for BD players and optical media for the purpose of participating in a joint Blu-ray Disc Patent Portfolio License being facilitated by MPEG LA. The Sonic technology covered in the ‘621 patent allows for updating or augmenting multimedia content on portable storage media including CD, DVD, UMD, flash memory, and HD DVD. In addition to Sonic's intention to participate in the Blu-ray Disc Patent Portfolio License, the company will continue to license the ‘621 patent directly to content owners, online service providers, software developers, game console manufacturers, consumer electronics companies, in-game advertisers, and other industry partners developing online services and non-BD applications.

Sonic's dynamic content revision technology enables publishers of content on any portable storage media to update or augment that content over the Web or through a local cache. Movie studios, for example, can replace trailers or change menu selections, and game console software makers can deliver in-game advertisements over the internet, providing a cost-effective way to keep content "fresh" and deliver ongoing value-added promotions and e-commerce offerings to form a more direct relationship with the entertainment viewer. The same technology is already widely-licensed by major Hollywood studios today for use on standard-definition DVD releases of InterActual-enabled titles such as Lord of the Rings: Return of the King, Harry Potter and the Prisoner of Azkaban, and the Star Wars Trilogy.
