To reset this unit
Bitstream
This is the digital form of multi-channel audio data (e.g., 5.1 channel)
before it is decoded into its various channels.
CPPM (Content Protection for Prerecorded Media)
A copy protection system used for DVD-Audio files. This unit
supports CPPM.
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.
Decoder
A decoder restores the coded audio signals on DVDs to normal. This
is called decoding.
DivX
A video compression format developed by DivXNetworks, Inc. that
compresses video files without any considerable loss of video
quality.
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. A large amount of audio information can
be recorded on one disc using this method.
When recording on this unit Dolby Digital (2 channel) is the default
audio.
Down-mixing
This is the process of remixing the multi-channel audio found on
some discs into two channels. It is useful when you want to listen to
the 5.1-channel audio recorded on DVDs through your television’s
speakers. Some discs prohibit down-mixing and this unit can then
only output the front two channels.
[DVD-A]
Tracks that do not allow down-mixing will not play correctly
on this unit except when connecting with an HDMI cable to an
amplifier that meets HDMI Ver. 1.1 standards and is CPPM
compatible.
DPOF (Digital Print Order Format)
DPOF is the standard printing format for still picture data taken by a
digital camera, etc. It is used for automatic printing at a photo
developing store or on your home printer.
Drive
In the instance of this unit, this refers to the hard disk (HDD), disc
(DVD) and SD card (SD). These perform the reading and writing of
data.
DTS (Digital Theater Systems)
This surround system is used in many movie theaters. There is good
separation between the channels, so realistic sound effects are
possible.
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.
