DVD VIDEO (digital video disc, video)
(page 11)
A disc that contains up to eight hours of moving
pictures on a disc the same diameter as a CD
(compact disc).
The data capacity of a single-layer and single-
sided DVD (digital video disc) is 4.7 GB (Giga
Byte), which is 7 times that of a CD (compact
disc). The data capacity of a double-layer and
single-sided DVD (digital video disc) is 8.5 GB, a
single-layer and double-sided DVD (digital video
disc) is 9.4 GB, and double-layer and double-sided
DVD (digital video disc) is 17 GB.
The picture data uses the MPEG (moving picture
experts group) 2 format, which is a worldwide
standard of digital compression technology. The
picture data is compressed to about 1/40 (average)
of its original size. The DVD (digital video disc)
also uses a variable rate coding technology that
changes the data to be allocated according to the
status of the picture. Audio information is
recorded in a multi-channel format, such as Dolby
Digital, allowing you to enjoy a more real audio
presence.
Furthermore, various advanced functions such as
the multi-angle, multilingual, and Parental
Control functions are provided on the DVD
(digital video disc).
Hard disc drive (page 2)
A hard disc drive is a whole mechanical system
that consists of discs and drive. Discs are flat,
circular, rigid plates coated with a thin magnetic
media. Magnetic heads record data on the rapidly
spinning discs, and this enables the speedy and
efficient reading and writing of data.
Interlace format (page 19)
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.
Original (page 71)
Titles actually recorded on a HDD/DVD-RW (VR
mode) (hard disc drive/digital video disc-
rewritable, minus RW (Video Recording mode)).
Erasing original titles frees up disc space.
Playlist (page 71)
Playback information created from the actual
recordings on a HDD/DVD-RW (VR mode) (hard
disc drive/digital video disc-rewritable, minus
RW (Video Recording mode)). A Playlist leaves
the original titles as they are, and contains only the
information needed to control playback. A Playlist
title takes up very little disc space.
Progressive format (page 19)
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.
Title (page 65)
The longest section of a picture or music feature
on a DVD (digital video disc), movie, etc., in
video software, or the entire album in audio
software.
Track (page 65)
Sections of a music feature on a CD/VIDEO CD
(compact disc/video compact disc) (the length of a
song).
