4 TERMINOLOGY
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.
Media Library: The Media Library refers to the
content stored on the DMC 1000’s internal hard-
disc drive. It contains all of the content that you
have transferred to the DMC 1000, including
copies of audio CDs, captures of audio streams
from the Auxiliary Analog Audio Inputs, and MP3
audio and JPEG image files transferred from
memory cards, discs or USB drives. The Media
Library automatically organizes the content so
that you may view it by track name, album, artist,
genre, cover art (when available) or playlists that
you have created. When a multizone system has
been connected, each zone may access different
content stored in the Media Library. When con-
nected to other properly programmed devices in
the home using the Network Jack or the RS-232
Port, the Media Library may be used as a server,
allowing you to enjoy content throughout your
home.
Multizone: A multizone system is used to dis-
tribute audio to various rooms in the house so
that the occupants of each room may independ-
ently choose different program material. The
DMC 1000 permits up to four different zones to
stream audio simultaneously. Multizone control is
usually set up by the custom installer, using
either control devices connected to a home net-
work, or devices connected to the DMC 1000’s
RS-232 port.
Server: A server is a computer device with a
large amount of storage that delivers content to
other devices. The DMC 1000 may be accessed
as a server from a home network when appropri-
ate devices are connected. When placed in Server
Mode, the DMC 1000 may still be used as a serv-
er, even though its four zones are inactive.
Zone: A zone is a section of a multizone system
in which all loudspeakers in the zone play the
same source program. By connecting the DMC
1000’s audio outputs for a specific zone to a
multichannel amplifier, you may include a num-
ber of loudspeakers in a variety of room locations
within the zone. Example: A four-channel amplifi-
er connected to the Zone 2 Outputs may power a
pair of speakers in the living room and a stereo
ceiling speaker in the connected dining room, so
that you and your guests may enjoy the same
program anywhere within the zone.
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 of the DMC 1000 to the standard
composite or S-video inputs of a TV or recorder.
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 output
of the DMC 1000 via its HDMI output, your dis-
play must be HDCP-compliant. Virtually all dis-
plays with HDMI inputs are HDCP-compliant, but
not all DVI-equipped displays are. If you are
using the DMC 1000 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
DMC 1000 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 DMC 1000 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.
