READ THIS BEFORE OPERATING
YOUR UNIT
Install this DVD-Player in a well ventilated, cool,
dry, clean place with at least 10 cm on the top,
10 cm on the left and right, and 10 cm at the
back – away from direct sunlight, heat sources,
vibration, dust, moisture, and/or cold.
Avoid installing this unit where foreign object
may fall onto this unit and/or this unit may be
exposed to liquid dripping or splashing. On the
top of this unit, do not place:
– Burning objects (i.e. candles), as they may
cause fire, damage to this unit, and/or personal
injury.
– Containers with liquid in them, as they may fall
and liquid may cause electrical shock to the
user and/or damage to this unit.
Do not cover this unit with a newspaper, table-
cloth, curtain, etc. in order not to obstruct heat
radiation. If the temperature inside this unit rises,
it may cause fire, damage to this unit, and/or
personal injury.
Install this unit near the AC outlet and where the
AC power plug can be reached easily.
This unit is not disconnected from the AC power
source as long as it is connected to the wall
outlet, even if this unit itself is turned off. This
state is called the standby mode. In this state,
this unit is designed to consume a very small
quantity of power.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPLIANCE
TO RAIN OR MOISTURE.
Terminology
Since they share some of the characteristics and
technology of CD players, many of the terms and
operational concepts used in a DVD player are
similar to what you may be familiar with from CD
players and changers, or older video disc formats
such as Laser Disc. However, if this is your first
DVD product, some of the terms used to describe
the features of a DVD player may be unfamiliar.
The following explanations should solve some of
the mysteries of DVD, and help you to enjoy all
the power and flexibility of the DVD format and
the DVD.
With the arrival of DVD, disc data capacity has
increased dramatically. On a DVD Video disc most
of this capacity is taken up by MPEG 2 video and
the multichannel movie soundtrack in Dolby
Digital and/or DTS. This information is
compressed.
Aspect Ratio: This is a description of the width
of a video image in relation to its height.
A conventional video screen is four units wide for
every three units of height, that’s why the ratio is
called ”4:3”. Newer wide aspect ratio video
displays are 16 units wide for every nine units of
height, making them more like the screen in a
movie theater. The program material on a DVD
may be recorded in either format and, in
addition, you may configure the DVD to play
back in either format, depending on the features
recorded on a disc.
Component Video: This form of video signal
eliminates many of the artifacts of traditional
composite video signals by splitting the signal
into a separate luminance channel (the “Y”
signal channel) and two color-difference signals
(the Pr and Pb signal channels). With a
component video connection, you will see
greater picture resolution and eliminate many
picture imperfections such as the moiré patterns
often seen on check-patterned cloth. However, in
order to benefit from component video, you must
have a video display with Y/Pr/Pb component
video inputs. Do not connect the component
video outputs to the standard composite or S-
video inputs of a TV or recorder.
Group: The individual tracks on a DVD-Audio
disc may be combined into Groups. There may be
more than one Group on a disc. Depending on
the way a disc’s producers create the program,
the Groups can contain different program
material, or they may repeat the disc’s content in
different audio formats, such as 5.1 audio or
high-resolution stereo.
HDCP (High-Bandwidth Digital Content
Protection): HDCP is the specification for
protecting digitally encoded content from
unauthorized copying when it is transmitted from
a DVD player (or other video source) to a video
display using HDMI or DVI connections. In order
to take advantage of the high-resolution HDMI
output, your display must be HDCP-compliant.
Virtually all displays with HDMI inputs are HDCP-
compliant, but not all DVI-equipped displays are.
If you are using the player with an optional
HDMI-to-DVI cable or adapter, check the owner’s
manual for your display to determine whether it
is HDCP-compliant.
HDMI ™ (High-Definition Multimedia
Interface ™ ): HDMI is a serial-bus form of
communication between the DVD player and the
video display or audio/video receiver. With 5Gbps
of bandwidth, it is capable of passing
uncompressed digital audio and high-definition
digital video using a single cable. With HDMI, the
player is capable of outputting high-resolution
(720p or 1080p) video and 5.1-channel Dolby
Digital or DTS digital audio, with the convenience
of just a single cable connection.
JPEG Files: JPEG stands for the Joint
Photographic Experts Group, which developed a
standard for compressing still images, such as
photographs. JPEG files may be created on a
personal computer by importing images from a
digital camera, or scanning printed photographs.
These files may be burned onto a compact disc.
The player is capable of recognizing JPEG files
and enabling you to view them on your video
screen.
Title: For a DVD, a title is defined as an entire
movie or program. There can be as many chapters
within a title as the producers decide to include.
Most discs include only one title, but some may
have more than one, to give you a “Double
Feature” presentation.
Chapter: DVD programs are divided into
chapters and titles. Chapters are the sub-sections
programmed into a single title on a disc.
Chapters may be compared to the individual
tracks on an audio CD.
