The picture data uses the MPEG 2 format, a
worldwide standard of digital compression
technology. The picture data is compressed to
about 1/40 of its original size. DVD also uses
variable rate coding technology that processes
allocated data according to the status of the
picture.
The audio data is recorded in Dolby Digital as
well as in PCM, allowing you to enjoy more
realistic audio presence.
Furthermore, various advanced functions such
as the multi-angle, multilingual, and Parental
Control functions are provided with the DVD.
File
Section of a picture on a data CD containing
JPEG image files.
Film based software, Video based
software
DVDs can be classified as Film based or Video
based software. Film based DVDs contain the
same images (24 frames per second) that are
shown at movie theatres. Video based DVDs,
such as television dramas or sit-coms, displays
images at 30 frames (or 60 fields) per second.
Interlace format (Interlaced
scanning)
The Interlace format is the NTSC standard
method for displaying TV images at 30 frames
per second. Each frame is scanned twice -
alternately between the even numbered scanning
lines and then odd numbered scanning lines, at
60 times per second.
Multi-angle function
Various angles of a scene, or viewpoints of the
video camera are recorded on some DVDs.
Multilingual function
Several languages for the sound or subtitles in a
picture are recorded on some DVDs.
Neo:6
Developed by Digital Theater Systems, Inc.,
applies a conventional 2-channel or Dolby
Digital source signal to a high-precision, digital
matrix decoder to achieve 6.1 channel surround
playback.
CINEMA mode allows for more separation of
channels to enhance the 6.1 channel effect, and
is best suited for movies.
MUSIC mode allows the front L and R channels
to go unprocessed for optimum stereo, with the
addition of the surround components adding a
special quality to the sound.
Parental Control
A function of the DVD to limit playback of the
disc by the age of the viewer according to the
limitation level in each country. The limitation
varies from disc to disc; when it is activated,
playback is completely prohibited, violent
scenes are skipped or replaced with other scenes
and so on.
Playback Control (PBC)
Signals encoded on VIDEO CDs (Version 2.0)
to control playback.
By using menu screens recorded on VIDEO
CDs with PBC functions, you can enjoy playing
simple interactive programs, programs with
search functions, and so on.
Progressive format (sequential
scanning)
In contrast to the Interlace format, the
progressive format can reproduce 60 frames per
second by reproducing all scanning lines (525
lines for the NTSC system). The overall picture
quality increases and still images, text and
horizontal lines appear sharper. This format is
compatible with the 525 progressive format.
Region Code
This receiver is used to protect copyrights. A
region number is allocated on each DVD system
or DVD disc according to the sales region. Each
region code is shown on the receiver as well as
on the disc packaging. The receiver can play the
discs that match its region code. The receiver
can also play discs with the “
” mark. Even
when the region code is not shown on the DVD,
the region limit may still be activated.
Scene
On a VIDEO CD with PBC (playback control)
functions, the menu screens, moving pictures
and still pictures are divided into sections called
“scenes.”
