GLOSSARY
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, making it almost square. 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 HS 300 to play back in either format, depending
on the features recorded on a disc.
Chapter:
DVD programs are divided into chapters and titles. Chapters
are the subsections programmed into a single title on a disc. Chapters
may be compared to the individual tracks on an audio CD. Press the
Disc Menu Button to see a listing of the chapters 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 of the DVD 38
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 output of the DVD 38 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 38 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. It is capable of passing digital audio and high-
definition digital video using a single cable. With HDMI, the DVD 38 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 photo-
graphs. These files may be burned onto a compact disc. The DVD 38
is capable of recognizing JPEG files and enabling you to view them on
your video screen.
MP3 Files:
MP3 is an audio compression format that was developed
by the Motion Picture Experts Group as an adjunct to the MPEG-1 video
compression format. A number of encoding software programs are
available for transferring CDs and other audio programs into the MP3
format. The main benefit of MP3 is that it reduces the size of audio files
considerably, depending on the amount of compression selected during
the encoding process, enabling you to store many more songs on
one compact disc than in the standard audio CD format. The DVD 38
is capable of playing MP3 files stored on a disc using its advanced
graphic interface.
MPEG-2 files:
MPEG stands for the Motion Pictures Expert Group,
which defines digital audio/video standards. The MPEG-2 format is
a method of compressing video presentations, and is the standard
generally used for television broadcasting and DVD, with some minor
modifications appropriate to each type of use.
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-angle scenes. In addition, the
DVD 38’s angle indicator will remain lit in the front-panel display for the
duration of multi-angle availability.
Progressive Scan:
Progressive-scan playback takes the original video
signal on the disc and formats it as a high-scan-rate output with twice
the scan lines of conventional video images. Progressive-scan outputs
must be connected to “digital-ready” or high-definition video displays,
regardless of the technology of the specific display (e.g., conventional
direct-view television, front or rear projector, plasma display panel or
LCD). In some cases, the displays may have special inputs for use with
high-scan-rate inputs, and in others you may need to make adjustments
to the display’s setup menus to make certain that the inputs used are
configured for an “HD” signal. Although the progressive-scan output
uses the component video jacks, it is not compatible with older conven-
tional analog video displays, even when they have component inputs,
unless you change the Scan Rate setting in the Video Setup submenu.
Reading
or
Loading:
This is a message that you will see when you
first press the Play Button. It refers to the fact that the player must first
examine the contents of the disc to determine its type, and then extract
the information about the 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 38 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.
