GB, a single-layer and double-sided DVD is
9.4 GB, and double-layer and double-sided
DVD is 17GB.
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 (average) of its
original size. The DVD 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 with
the DVD.
DVD-RW (page 6)
A DVD-RW is a recordable and rewritable
disc with the same size as the DVD VIDEO.
The DVD-RW can be recorded in two
different modes: VR mode and Video mode.
VR (Video Recording) mode enables various
programming and editing functions, some of
which are limited in the case of Video mode.
Video mode complies with DVD VIDEO
format and can be played on other DVD
players while a DVD-RW recorded in VR
mode can only be played on DVD-RW
compliant players. The “DVD-RW”
appearing in this manual, and the on-screen
displays refer to DVD-RWs in VR mode.
Film based software, Video based
software (page 76)
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.
Index (CD)/Video Index (VIDEO CD) (page
10)
A number that divides a track into sections to
easily locate the point you want on a CD or
VIDEO CD. Depending on the disc, no index
may be recorded.
Interlace format (page 76)
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.
International standard coding system used to
compress audio digital signals authorized by
ISO/IEC. MPEG 1 conforms to up to 2-
channel stereo. MPEG 2, used on DVDs,
conforms to up to 7.1-channel surround.
Progressive format (page 76)
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 player is compatible with the
480 (525) progressive format.
Scene (page 10)
On a VIDEO CD with PBC (playback
control) functions, the menu screens, moving
pictures and still pictures are divided into
sections called “scenes.”
Super Audio CD (page 6)
A Super Audio CD disc can reproduce sounds
that are extremely faithful to the original
sound by use of DSD (Direct Stream Digital)
technology. This technology utilizes a
sampling frequency of 2.8224 MHz, which is
64 times that of a conventional CD, and 1-bit
quantization that enables the disc to hold 4
times the amount of information that a
standard PCM format CD can hold. Super
Audio CDs are divided into the following
types.
• Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
