26 TERMINOLOGY
DVD 28 Digital Versatile Disc Player
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” sig-
nal 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 imperfec-
tions such as the moiré patterns often seen on
check-patterned cloth. However, in order to ben-
efit from component video, you must have a
video display with Y/Pr/Pb component video
inputs. Do not connect the component video out-
puts of the DVD 28 to the standard composite or
S-video inputs of a TV or recorder.
HDCP (High-Bandwidth Digital Content
Protection):
HDCP is the specification for pro-
tecting digitally encoded content from unautho-
rized 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 output of the
DVD 28 via its 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
DVD 28 with an optional HDMI-to-DVI cable or
adapter, check the owner’s manual for your dis-
play to determine whether it is HDCP-compliant.
HDMI ™ (High-Definition Multimedia
Interface ™ ): HDMI is a serial-bus form of com-
munication between the DVD player and the
video display or audio/video receiver. With 5Gbps
of bandwidth, it is capable of passing uncom-
pressed digital audio and high-definition digital
video using a single cable. With HDMI, the
DVD 28 is capable of outputting high-resolution
(720p or 1080i) 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 DVD 28 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.
Progressive Scan: Due to the immense data
storage capacity of DVD, images are nowadays
stored progressively (intact, rather than inter-
laced). This allow all of the lines in each frame
(odd and even) to be shown at the same time.
Harman Kardon Cinema Lounge comes with true
progressive scan video output resulting in a 40%
greater light output than a conventional TV and
a stunningly detailed, high definition image with
absence of visible scanlines and motion artifacts.
WMA Files: WMA (Windows Media ® Audio) is
an audio compression format that was developed
by the Microsoft
® Corporation for use with its
Windows Media Player. WMA files can be even
smaller in size than MP3 files, while maintaining
similar quality. The DVD 28 is among those DVD
players capable of playing discs containing WMA
files. Note that Windows Media Player uses other
file formats; however, the DVD 28 is only capable
of playing files that end in the “.wma” extension.
See page 5 for more information on WMA file
support.
Multiple Angle: DVDs have the capability to
show up to four different views of the same
scene in a program. When a disc is encoded with
multiple-angle information, pressing the Angle
button will enable you to switch between these
different views. Note that at present, few discs
take advantage of this capability and, when they
do, the multiple-angle technology may only be
present for short periods of time within the disc.
Producers will usually insert some sort of icon or
graphic in the picture to alert you to the
availability of multiple viewing angles.
Reading: This is a message that you will see
after you´ve loaded the disc and the tray has
closed. It refers to the fact that the player must
first examine the contents of the disc to see if it
is a CD or DVD, and then extract the information
about the type of material on the disc, such as
languages, aspect ratios, subtitles, number of
titles and more. The slight delay while the
contents of the disc are read is normal.
Resume: The operation of the Stop Button on
the DVD works differently from what you are
used to on CD players. On a traditional CD
player, when you press the Stop button, the unit
does just that: it stops playback. On a CD player,
when you press the start button again, the disc
starts from the beginning. With the DVD,
however, you have two options when playing
DVD discs. Pressing Stop once will stop playback,
but it actually puts the unit in the Resume mode.
This means that you can turn the machine off
and, when you press play the next time, the disc
will resume or continue from the point on the
disc where the Stop button was pressed. This is
helpful if you are watching a movie and must
interrupt your viewing session but wish to pick
up where you left off. Pressing the Stop button
twice will stop the machine in a traditional
manner and, when the disc is played again, it will
start from the beginning.
In resume mode, the cover of the DVD will be
displayed, if available. Otherwise, the
Harman Kardon screen will appear.
DivX
DivX is the name of a revolutionary new video
codec which is based on the MPEG-4 compres-
sion standard for video. This DVD player will play-
back discs created with DivX software. The DVD
player’s playback functionalities of DivX video
discs will vary depending on the DivX software
version used for creating your movies. For more
information about the different software versions
of DivX, please go to www.divx.com.
