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.1.3a with Deep Colour)
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.
