AVCHD
AVCHD is a new format (standard) for High Definition
video cameras that can be used to record and play
high-resolution HD images.
BD-J
Some BD-Video discs contain Java applications, and
these applications are called BD-J. You can enjoy
various interactive features in addition to playing
normal video.
Bitstream
This is the digital form of multi-channel audio data
(e.g., 5.1 channel) before it is decoded into its various
channels.
CPRM (Content Protection for Recordable Media)
CPRM is technology used to protect broadcasts that
are allowed to be recorded only once. Such
broadcasts can be recorded only with CPRM
compatible recorders and discs.
Deep Colour
This unit incorporates HDMI (V.1.4, Content Type)
technology that can reproduce greater colour
gradation (4096 steps) when connected to a
compatible TV.
You can enjoy exceptionally rich, natural-looking
colours, with smooth, detailed gradation and minimal
colour banding.
[A lower colour gradation (256 steps), without Deep
Colour, will be reproduced if connected to a TV which
does not support Deep Colour. The unit will
automatically set appropriate output to suit the
connected TV.]

Dolby Digital
This is a method of coding digital signals developed
by Dolby Laboratories. Apart from stereo (2-channel)
audio, these signals can also be multi-channel audio.
Dolby Digital Plus
Multi-channel audio and higher audio quality is made
possible using Dolby Digital Plus. BD-Video supports
up to 7.1 channel output.
Dolby TrueHD
Dolby TrueHD is a very high quality audio format that
reproduces the studio master audio. BD-Video
supports up to 7.1 channel output.
Down-mixing
This is the process of remixing the multi-channel
audio found on some discs into fewer channels.
DTS (Digital Theater Systems)
This surround system is used in many movie
theatres. There is good separation between the
channels, so realistic sound effects are possible.
DTS-HD
DTS-HD is a high-quality, sophisticated audio format
used in movie theatres. Previous DTS Digital
Surround-compatible equipment can play DTS-HD as
DTS Digital Surround audio. BD-Video supports up to
7.1 channel output.
Dynamic range
Dynamic range is the difference between the lowest
level of sound that can be heard above the noise of
the equipment and the highest level of sound before
distortion occurs.
Dynamic range compression means reducing the gap
between the loudest and softest sounds. This means
you can listen at low volumes but still hear dialogue
clearly.
