Bitstream

This is the digital form of multiple channel audio data (e.g., 5.1 chan- nel) before it is decoded into its various channels.

Decoder

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

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 5.1-channel audio. A large amount of audio information can be recorded on one disc using this method.

Dolby Pro Logic

A surround system where a 4-channel audio track is recorded as 2 channels and then is restored to 4 channels for play. The surround channel is monaural and can reproduce up to 7 kHz.

DTS (Digital Theater Systems)

This surround system is used in many movie theaters around the world. 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.

Frame still and field still

Frames are the still pictures that go together to make a moving pic- ture. There are about 30 frames shown each second.

One frame is made up of two fields. A regular television shows these fields one after the other to create frames.

A still is shown when you pause a moving picture. A frame still is made up of two alternating fields, so the picture may appear blurred, but overall quality is high.

A field still is not blurred, but it has only half the information of a frame still so picture quality is lower.

I/P/B

MPEG 2, the video compression standard adopted for use with DVD-Video, codes frames using these 3 picture types.

I:Intra coded picture (I-picture)

This is the standard picture and is a complete picture in itself. This means it has the best picture quality and is the best to use

when adjusting the picture.

P:Predictive coded picture (P-picture)

This picture is calculated based on past I or P-pictures.

B:Bidirectionally-predictive coded picture (B-picture)

This picture is calculated by comparing past and future I and P-pictures so it has the lowest volume of information.

Linear PCM (pulse code modulation)

These are uncompressed digital signals, similar to those found on CDs.

MP3

A method of compressing audio, MPEG Audio Layer 3 (MP3) allows audio to be reduced to up to one tenth its original size without overtly hurting audio quality.

When creating MP3 files to play on this unit

Disc formats: ISO9660 level 1 and level 2 (except for extended for- mats)

Files: MP3 files with the suffix “.mp3” or “.MP3”

To have this unit play files in a certain order, prefix folder and file names with numbers in the order you want to play them. This may not work in all cases.

Not compatible with multi-session recordings

If you record MP3 onto CD-R/CD-RW over a number of sessions, this unit can play only the recordings made in the first session.

Playback control (PBC)

If a Video CD has playback control, you can select scenes and infor- mation with menus.

Reference

Disc handling

Do not use irregularly shaped discs, such as heart-shaped. (These can damage the unit.)

How to hold a disc

Do not touch the recorded surface.

If the surface is dirty

Wipe it with a damp cloth and then wipe dry.

If the disc is brought from a cold to a warm envi-

ronment, moisture may form on the disc

Wipe with a soft, dry, lint-free cloth before using the disc.

Handling precautions

Do not write on the label side with a ball-point pen or other writing instrument.

Do not use record cleaning sprays, benzine, thinner, static electric- ity prevention liquids or any other solvent.

Do not attach labels or stickers to discs. (Do not use discs with exposed adhesive from tape or left over peeled-off stickers.)

Do not use scratch-proof protectors or covers.

Do not use discs printed with label printers available on the market.

Do not place or store discs in the following places

Locations exposed to direct sunlight

Humid or dusty locations

Locations directly exposed to a heat vent or heating appliance
