This is a signal compressed and converted into digital form. It is 
converted back to a multi-channel audio signal, e.g., 5.1-channel, by 
a decoder.

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.

A decoder restores the coded audio signals on DVDs to normal. This 
is called decoding.

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.

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 TV’s speakers. 
Some discs prohibit down-mixing. If this is the case, this unit can only 
output the front two channels.
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.

This surround system is used in many movie theaters. There is good 
separation between the channels, so realistic sound effects are 
possible.

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 hear dialogue clearly at low volume.

DVD-Videos are recorded using either film or video. The unit can 
determine which type has been used, then uses the most suitable 
method of progressive output.
Film:   Recorded at 25 frames per second (PAL discs) or 24 frames 

per second (NTSC discs). (NTSC discs recorded at 30 frames 
per second as well.)

 

Generally appropriate for motion picture films.

Video:  Recorded at 25 frames/50 fields per second. (PAL discs) 

or 30 frames/60 fields per second (NTSC discs). Generally 
appropriate for TV drama programmes or animation.

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 finalise 
DVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R,and +R DL on 
the unit. After finalising, the disc becomes play-only and you can no 
longer record or edit. However, finalised DVD-RW can be formatted 
to become recordable.

Formatting is the process of making media such as DVD-RAM 
recordable on recording equipment.
You can format DVD-RAM, DVD-RW (only as DVD-Video format) and 
+RW on this unit.
Formatting irrevocably erases all contents.

Frame refers to the single images that constitute the video you see 
on your TV. Each frame consists of 2 fields.

A frame still shows 2 fields, so there may be some blurring between 
them, but picture quality is generally better.
A field still shows less picture information so it may be rougher, but 
there is no blurring.

HDMI is a next-generation digital interface for consumer electronic
products. Unlike conventional connections, it transmits 
uncompressed digital video and audio signals on a single cable. This 
unit supports high-definition video output [720p (750p), 1080i (1125i), 
and 1080p (1125p)] from HDMI AV OUT terminals. To enjoy high-
definition video a high definition compatible television is required.

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 
benefit of JPEG is less deterioration in picture quality considering the 
degree of compression.

These are uncompressed digital signals, similar to those found on
CDs. LPCM sound is available when recording in XP mode.

A standard for efficiently compressing and expanding colour video. 
MPEG2 is a compression standard used for DVD and digital 
broadcasting. This unit records programmes using MPEG2.

An audio compression method that compresses audio to 
approximately one-tenth of its size without any significant loss of 
audio quality. You can play MP3s you have recorded onto DVD-R, 
DVD-R DL, CD-R and CD-RW.

In general, DVD-Video are produced with the intention that they will 
be viewed on a widescreen TV (16:9 aspect ratio), so images often 
don’t fit regular TVs (4:3 aspect ratio). 2 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.

If a Video CD has playback control, you can select scenes and 
information with menus displayed on the screen.
(The unit is compatible with version 2.0 and 1.1.)

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.
