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.
Decoder
A decoder restores the coded audio signals on DVDs to normal. This 
is called decoding.
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.
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 dialog clearly.
EPG (Electronic Program Guide)
This is a system used to display the television program list on 
televisions, computers and cellular phones. Data is transmitted using 
the internet or television waves. This unit is compatible with the 
method using television waves. You can use the television program 
list for functions such as scheduled recording.
Film and video
DVD-Video 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.
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, DVD-RW (DVD-Video format) and +R on this unit.
After finalizing, the disc becomes play-only and you can no longer 
record or edit. However, finalized DVD-RW can be formatted to 
become recordable.
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) are stored.
Formatting
Formatting is the process of making media such as DVD-RAM 
recordable on recording equipment.
You can format the HDD, DVD-RAM, DVD-RW (only as DVD-Video 
format) and SD memory card on this unit. Formatting irrevocably 
erases all contents.
Frames and fields
Frames refer to the single images that constitute the video you see 
on your television. Each frame consists of two fields.
A frame still shows two fields, so there may be some blurring, but 
picture quality is generally better.
A field still shows less picture information so it may be rougher, but 
there is no blurring.
HDD (Hard disk drive)
This is a mass data storage device used in computers, etc. A disk 
with a surface that has been treated with magnetic fluid is spun and 
a magnetic head is brought in close proximity to facilitate the reading 
and writing of large amounts of data at high speed.
JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding color still pictures. If 
you select JPEG as the storage system on digital cameras, etc., the 
data will be compressed to 1/10–1/100 of its original size. The 
benefit of JPEG is less deterioration in picture quality considering 
the degree of compression.
LPCM (Linear PCM)
These are uncompressed digital signals, similar to those found on 
CDs. LPCM sound is available when recording in XP mode.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses audio to 
approximately one tenth of its size without any considerable loss of 
audio quality. You can play MP3 you have recorded onto CD-R and 
CD-RW.
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention that they be 
viewed on a widescreen television (16:9 aspect ratio), so images 
often don’t fit regular (4:3 aspect ratio) televisions. Two styles of 
picture, “Pan & Scan” and “Letterbox”, deal with this problem.
Pan&Scan: The sides are cut off so the picture fills 
the screen.
Letterbox: Black bands appear at the top and 
bottom of the picture so the picture itself 
appears in an aspect ratio of 16:9.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and 
information with menus.
(This unit is compatible with version 2.0 and 1.1.) 
Progressive/Interlace
NTSC, the video signal standard, has 480 interlaced (i) scan lines, 
whereas progressive scanning uses twice the number of scan lines. 
This is called 480p.
Using progressive output, you can enjoy the high-resolution video 
recorded on media such as DVD-Video.
Your television must be compatible to enjoy progressive video.
