Compatibility; Flexibility And Interactivity - Sony VAIO Blu-ray Disc Player Manual

What does this mean for me?
The limited capacity of DVDs results in video and audio files being
compressed to fit on a disc. This causes a quality reduction in the
picture and/or sound. The greater capacity of BD discs allows for
pristine picture quality and virtually full spectrum audio.

Compatibility

Blu-ray Disc™ offers a convergence of technology and
compatibility among a new generation of high definition movies,
video players, video recorders, personal computers, and gaming
systems.
And what about your current library of DVDs and CDs? The
Blu-ray Disc generation of home entertainment products will be
backward-compatible with your CDs, DVDs, and other optical disc
formats.

Flexibility and Interactivity

The technology built into each Blu-ray disc gives you, and industry
professionals creating high definition content, the tools to create a
viewing experience that up until now has not been possible for
home entertainment. For example:
• Multiple video layers can now be on the screen at the same
time. A presentation layer, customizable by a studio, allows the
content creator to place graphics on the screen on top of the
video or alongside it. Sitting on top of that layer is the Blu-ray
navigation layer that will allow you to interact with the menu
while the video is playing.
• Support for Java applications allows the video layer to be
re-sizable providing even greater flexibility. Imagine the
possibility of watching a movie and playing an interactive game
related to the movie—all at the same time.
