recordings, and provides a wide and deep sound
space.
DTS
Digital audio compression technology that the
Digital Theater Systems, Inc. developed. This
technology conforms to 5.1-channel surround.
The rear channel is stereo and there is discrete
subwoofer channel in this format. DTS provides
the same 5.1 discrete channels of high quality
digital audio. The good channel separation is
realized because the all channel data is recorded
discrete and processed in digital.
DVD
A disc that contains up to 8 hours of moving
pictures even though its diameter is the same as
a CD.
The data capacity of a single-layer and single-
sided DVD, at 4.7 GB (Giga Byte), is 7 times
that of a CD. Furthermore, the data capacity of a
dual-layer and single-sided DVD is 8.5 GB, a
single-layer and double-sided DVD 9.4 GB, and
a dual-layer and double-sided DVD 17 GB.
The picture data uses the MPEG 2 format, one of
the worldwide standards of digital compression
technology. The picture data is compressed to
about 1/40 of its original size. The DVD also
uses the variable rate coding technology that
changes the data to be allocated 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
Interlace format shows every other line of an
image as a single “field” and is the standard
method for displaying images on television. The
even number field shows the even numbered
lines of an image, and the odd numbered field
shows the odd numbered lines of an image.
Multi-angle function
Various angles, or viewpoints of the video
camera, for a scene 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
Compared to the Interlace format that alternately
shows every other line of an image (field) to
create one frame, the Progressive format shows
the entire image at once as a single frame. This
means that while the Interlace format can show
30 frames (60 fields) in one second, the
Progressive format can show 60 frames in one
second. The overall picture quality increases and
still images, text, and horizontal lines appear
sharper. This system is compatible with the 480
progressive format.
