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.

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 disc (DVD), SD card 
(SD) and PC card (PC). 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. 

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 DVD-RAM 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 DVD-RAM and memory cards on this unit. 
Formatting erases irrevocably 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.

JPEG (Joint Photographic Experts Group)

This is a system used for compressing/decoding colour 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 
feature 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

The PAL video signal standard has 625 (or 576) interlaced (I) scan 
lines, whereas progressive scanning, called 625P (or 576P), uses 
twice the number of scan lines. For the NTSC standard, these are 
called 525I (or 480I) and 525P (or 480P) respectively.
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.
Panasonic televisions with 625 (576)/50I · 50P, 525 (480)/60I · 60P 
input terminals are progressive compatible.

Protection

You can prevent accidental erasure by setting writing protection or 
erasure protection. 

Sampling frequency

Sampling is the process of converting the heights of sound wave 
(analog signal) samples taken at set periods into digits (digital 
encoding). Sampling frequency is the number of samples taken per 
second, so larger numbers mean more faithful reproduction of the 
original sound.

TIFF (Tag Image File Format)

This is a system used for compressing/decoding colour still pictures. 
A common format for storing high quality images on digital cameras 
and other devices.

Thumbnail

This refers to a miniature representation of a picture used to display 
multiple pictures in the form of a list.

VBR (Variable bitrate)

This is a method of video recording that adjusts the bit rate 
according to video signal.
