BD J: Blu-Ray Disc Java, BD-J for short, designates a Java variant that enables the storage and execution of interactive content on Blu-Ray players. Build on this platform, for example BD-Live and Blu-Ray Magic on.
Depending on the Blu-Ray profile, it is then possible to display picture-in-picture content and call up additional material for the film that has been inserted via a network connection. This can be, for example, short trailers, documentaries, games or even shopping services.
