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 Labo-
ratories. 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.

Dolby Pro Logic

Dolby Pro Logic

is an advanced decoder that derives 5 channel

surround (Left, Center, Right, Left and Right Surround) from any
stereo program material, whether or not it has been specifically
Dolby Surround encoded. Pro Logic

provides two full-range

surround channels, as opposed to Pro Logic’s single surround
channel.

Down-mixing

This is the process of remixing the multi-channel audio found on
some discs into two channels output. Some discs prohibit down-mix-
ing and this unit can then only output the front two channels.

Drive

In the instance of this unit, this refers to the hard disk (HDD) and
DVD. 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 pos-
sible.

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.

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 or DVD-R
etc. possible on equipment that can play such media. You can final-
ize DVD-R on this unit.
You cannot record onto or edit finalized discs.

Formatting

Formatting is the process of making media such as DVD-RAM
recordable on recording equipment.
You can format the HDD and DVD-RAM on this unit.
Formatting irrevocably erases all recordings on the disc.

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.

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.

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.

VBR (Variable bitrate)

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