"BD-J" mode

Introduction
"BD-J" mode was designed to offer the content provider almost unlimited functionality when creating interactive titles. It is based on Java 2 Micro Edition, so programmers will quickly be familiar with the programming environment for BD-J. Every Blu-ray Disc player will be equipped with a Java interpreter, so that it is capable of running discs authored in BD-J mode.

Internet connection
The BD-J system supports basic Internet protocols like TCP/IP and HTTP. The player may connect to the disc publisher's web site to unlock certain content on the disc (after certain conditions, like payment, are met), or dynamically display certain info (like theater playing schedules for a movie) on the screen. The disc's program may be extended with JPEG pictures or audio fragments downloaded from the Internet, or it can even stream full new audio/visual content to Local Storage.
