File
A JPEG image recorded on a DATA CD/DATA
DVD. (“File” is an exclusive definition for this
system.) A single file consists of a single image
or movie.
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 theaters. Video based DVDs,
such as television dramas or sit-coms, displays
images at 30 frames (or 60 fields) per second.
HDMI (high-definition multimedia
interface)
HDMI is an interface that supports both video
and audio on a single digital connection. The
HDMI connection carries standard to high
definition video signals and multi-channel audio
signals to AV components such as HDMI
equipped TVs, in digital form without
degradation. Since the video signals are
compatible with the current DVI (digital visual
interface) format, HDMI jacks can be connected
to DVI (digital visual interface) jacks by way of
an HDMI -DVI (digital visual interface)
converter cord. The HDMI specification
supports HDCP (high-bandwidth digital
contents protection), a copy protection
technology that incorporates coding technology
for digital video signals.
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.
Mica-reinforced-cellular-diaphragm
The Mica-reinforced-cellular-diaphragm is
made of a light weight and highly rigid
composite material that consists of Mica flake
and synthetic fiber.
It is constructed with layers of Mica flake. This
construction realizes diaphragm with low
density and high rigidity at the same time.
In this system, a Mica-reinforced-cellular-
diaphragm is used for the subwoofer.
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.
Parental Control
A function of the DVD to limit playback of the
disc by the age of the users 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 50 - 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 or 625 progressive
format.
Region Code
This system 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 system as well as on
the disc packaging. The system can play discs
that match its region code. The system can also
play discs with the “
” mark. Even when the
region code is not shown on the DVD, the region
limit may still apply.
