CPPM (Content Protection for Prerecorded Media)

Acopy 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

Aprocess 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.

	u	r
Frame	Field	Field

pA frame still shows two fields, so there may be some blurring, but picture quality is generally better.

pA 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.

the data will be compressed to 1/10–1/100 of its original size. The		Glossary/
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.,
feature of JPEG is less deterioration in picture quality considering		Service
the degree of compression.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses audio to		Product
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 1/60th 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 1/60th 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.
