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.

Film and video

DVDs are recorded using either film or video. Usually, film is record-

ed at 24 frames per second, the rate movies are filmed at, while

video is recorded at 30 frames per second.

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.

Interlace and progressive output

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.

The 480i video signals output from this unit's COMPONENT VIDEO

OUT terminals (Y, PB, PR) allow you to enjoy higher quality pictures

than if the signals were output from the video output terminal or S-

VIDEO OUT terminal. The COMPONENT VIDEO OUT terminals are

also able to handle 480p (progressive) video signals which are of

even greater resolution.

I/P/B

MPEG 2, the video compression standard adopted for use with DVD-

Video, codes frames using these 3 picture types.

h 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

oDisc formats: ISO9660 level 1 and level 2 (except for extended for-

mats)

Files: MP3 files with the suffix ".mp3" or ".MP3"

oTo 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.
