Reference Information
• User Browsable Slideshows
In DVD-Video, user browsable slide shows were not possible with uninterrupted audio. As a result of Blu-ray
Disc's ability to read data from the disc without interrupting the current audio/video stream, users can browse
through various still pictures while the audio remains playing. This applies not only to forward and backward
selecting: a user can make different selections on what picture to view (or selects from a screen presented with
thumbnail images) while the audio remains playing.
• Subtitles
In DVD-Video, subtitles were stored in the audio/video stream, and therefore they had limitations on the
number of languages and display styles. Again, it is due to Blu-ray Disc's ability to read data from the disc
without interrupting the current audio/ video stream, that subtitles can be stored independently on the disc.
A user may select different font styles, sizes and colors for the subtitles, or location on screen, depending on
the disc's offerings. Subtitles can be animated, scrolled or faded in and out.
• 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.
• Graphical User Interface
In BD-J mode, the author has complete freedom in designing the user interface. The interface is controllable
by user using standard navigational buttons on remote. It can display up to 32bit dynamically generated
graphics (millions of colors), and it supports the display of pictures in standard file formats like JPEG, PNG, etc.
• Playback control
The BD-J application can act as the sole interface to the disc's contents (thus replacing the players on-screen
controls as with discs authored in HDMV mode). The BD-J environment offers all of the playback features of
HDMV mode, including the selection of subtitle, trick play modes, angles, etc. Video can even be scaled
dynamically, so that it can be played in a small size in the corner of a menu, and resume full screen when a
selection is made
• Storage
ABlu-ray Disc player might contain a small amount of non-volatile system storage (flash memory).
This system storage can be used to store game scores, bookmarks, favorites from a disc, training course results,
etc. As a manufacturer's option, a Blu-ray Disc player may also be equipped with Local Storage (hard disk, to
allow large amounts of data like audio/video to be stored.
• 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.
• Conclusion
The Blu-ray Disc format for Movie Distribution offers two flexible profiles for the creation of titles. It was
designed to allow for the streamlined development of Blu-ray Disc (HD) and DVD-Video (SD) titles at the same
time, if needed. Basic menus and navigation can be identical. However, it also offers many new functions that
will benefit both the author (by offering flexible ways of creating disc content), as well as end users (by offering
exiting new functionality compared to DVD-Video).
