CPPM (Content Protection for Prerecorded Media)

A copy protection system used for DVD-Audio files. This unit

supports CPPM.

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.

Down-mixing

This is the process of remixing the multi-channel audio found of

some discs into two-channel output.

Some multi-channel DVD-Audio will prevent down-mixing of all or

part of their contents if this is the manufacturer’s intention.

This unit cannot down-mix these types of discs. (When the disc is

automatically down-mixed, audio will not be output correctly when

using headphones, etc. Audio is output only with the front two

channels, etc.)

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) 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.

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: Recorded at 24 or 30 frames per second. Generally

appropriate for motion picture films.

Video: Recorded at 30 frames/60 fields per second. Generally

appropriate for TV drama programs or animation.

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-R DL, DVD-RW (DVD-Video format), +R or +R DL 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 disc 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 DVD-RAM, DVD-RW (only as DVD-Video format),

+R, +R DL or +RW and SD memory card on this unit.

When you use DVD-RW, +R, +R DL or +RW, it must be formatted.

Formatting irrevocably deletes 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.

HDMI (High-Definition Multimedia Interface)

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,1080i) from HDMI

AV OUT terminal. To enjoy high-definition video a high-definition

compatible television is required.

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

feature of JPEG is less deterioration in picture quality considering

the degree of compression.

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 deletion by setting writing protection or

deletion 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.

Thumbnail

This refers to a miniature representation of a picture used to display

multiple pictures in the form of a list.

TIFF (Tag Image File Format)

This is a system used for compressing/decoding color still pictures, a

common format for storing high quality images on digital cameras

and other devices.

1080i

In one high definition image, 1080 alternating scan lines pass every

1/60

of a second to create an interlace image. Because 1080i more

than doubles current television broadcasts of 480i, the detail is much

clearer and creates a more realistic and rich image.

720p

In one high definition image, 720 scan lines pass at the same time

every 1/60

of a second to create a progressive image. Since

progressive video does not alternate scan lines like interlace, there

is a minimal amount of screen flicker.
