abstract:BD-J, or Blu-ray Disc Java, is a specification supporting Java ME (specifically the Personal Basis Profile of the Connected Device Configuration or CDC) Xlets for advanced content on Blu-ray Disc and the Packaged Media profile of Globally Executable MHP (GEM).
NetBlender has made plans official for new versions of its DoStudio authoring software, adding support for Blu-ray and BD-J features including BD Live.
While major studios may be able to create BD-J enhanced discs on their own, the idea is that this package can allow other professionals to make full featured discs without having to learn scripting.
