Glossary

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.
DHCP (Dynamic Host Configuration Protocol)
Provides a mechanism for automatically assigning network
information such as the IP address or Subnet mask sent by the
router and so on to this unit.
DNS server
A server which acts like a telephone directory and translates Internet
domain names into IP address.
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 DVD-Audio prevent down-mixing of all or part of
their contents. When playing such discs, or such parts of the disc,
unless the number of connected speakers is the same as the disc's
channel specification, audio will not be output properly.
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), SD card (SD) and PC card (PC). These perform the reading
and writing of data.

§
Folders can be created on other equipment. However, these folders cannot be selected as a transferring (dubbing) destination.
≥The folder cannot be displayed if the numbers are all "0" (e.g., DCIM000 etc).
≥If a folder name or filename has been input using other equipment, the name may not be displayed properly or you may not be able to play or
edit the 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.
Film and video
DVD-Videos are recorded using either film or video. This unit can
determine which type has been used, then uses the most suitable
method of progressive output.
For PAL
Film is 25 frames per second.
Video is 50 fields per second (two fields making up one frame).
For NTSC
Film is 24 or 30 frames per second, with motion picture film generally
being 24 frames per second.
Video is 60 fields per second (two fields making up one frame).
Finalize
A process that makes play of a recorded CD-R, CD-RW, DVD-R, etc.
possible on equipment that can play such media. You can finalize
DVD-R on this unit.
After finalizing, the disc becomes play-only and you can no longer
record or edit.
Folder
This is a place on the hard disk or memory card where groups of
data are stored together. In the case of this unit, it refers to the place
where still pictures (JPEG, TIFF) or MPEG4 are stored.
