Glossary
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
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.
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
DVD-Videos are recorded using either film or video. Usually, film is
recorded 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
picture. 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 video signals output from this unit's
COMPONENT VIDEO OUT terminals (Y, P
higher quality pictures than if the signals were output from the
VIDEO OUT terminal or S VIDEO OUT terminal.
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
This picture has the best quality and is the best to use when
adjusting the picture.
P: Predictive coded picture
This picture is calculated based on past I or P-pictures.
B: Bidirectionally-predictive coded picture
This picture is calculated by comparing past and future I and
P-pictures so it has the lowest volume of information.
Maintenance
To clean this unit, wipe with a soft, dry cloth.
≥Never use alcohol, paint thinner or benzine to clean this unit.
≥Before using chemically treated cloth, read the instructions that
came with the cloth carefully.

Linear PCM (pulse code modulation)
These are uncompressed digital signals, similar to those found on
CDs.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and
information with menus.
WMA, MP3, and CD text information
≥Discs must conform to ISO9660 level 1 or 2 (except for extended
formats).
≥This unit is compatible with multi-session but if there are a lot of
sessions it takes more time for play to start. Keep the number of
sessions to a minimum to avoid this.
≥The order tracks appear in the menus may differ to the order shown
on your computer.
[WMA]
≥Noise may occur when playing WMA files.
≥You cannot play WMA files that are copy protected.
[MP3]
≥This unit is not compatible with ID3 tags.
≥If you play an MP3 track that includes still picture data, it will take
some time before the music itself starts playing and the elapsed
time will not be displayed during this time. Even after the track
starts, the correct play time will not be displayed.

[CD] (CD text only)
When making your own CD text discs
The unit plays the tracks in the order you record them so you do
not have to prefix the titles with numbers.

WMA is a compression format developed
by Microsoft Corporation. It achieves the
same sound quality as MP3 with a file size
that is smaller than that of MP3.

Before moving the unit, ensure the disc tray is
empty.
Failure to do so will risk severely damaging the disc and
the unit.
