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.

DTS (Digital Theatre Systems)
This surround system is used in many movie theatres 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 fi lm or video. This unit can
determine which type has been used, then uses the most suitable
method of progressive output.

Frame still and fi eld 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 fi elds. A regular television shows these
fi elds 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 fi elds, so the picture may appear blurred,
but overall quality is high.
A fi eld still is not blurred, but it has only half the information of a frame
still so picture quality is lower.

HDMI (High-Defi nition 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-defi nition video output (720p, 1080i, 1080p) from the HDMI
AV OUT terminal. To enjoy high-defi nition video, a high-defi nition
compatible television is required.

: 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

JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding colour 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 benefi t
of JPEG is less deterioration in picture quality considering the degree
of compression.

Linear PCM (Pulse Code Modulation)
These are uncompressed digital signals, similar to those found on
CDs.

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.

MPEG4
A compression system for use on mobile devices or a network, that
allows highly effi cient recording at a low bit rate.

Playback control (PBC)
If a Video CD has playback control, you can select scenes and
information with menus.

Progressive/Interlaced
The PAL video signal standard has 576 interlaced (i) scan lines,
whereas progressive scanning, called 576p, uses twice the number
of scan lines. For the NTSC standard, these are called 480i and 480p
respectively.
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.

Sampling frequency
Sampling is the process of converting the heights of sound wave
(analogue 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.

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