Dolby Digital (page 22, 58)
Digital audio compression technology
developed by Dolby Laboratories. This
technology conforms to multi-channel
surround sound. The rear channel is stereo
and there is a discrete subwoofer channel in
this format. Dolby Digital provides the same
discrete channels of high quality digital audio
found in “Dolby Digital” theater surround
sound systems. Good channel separation is
realized because all of the channel data are
recorded discretely and little deterioration is
realized because all channel data processing
is digital.

DVD (page 6)
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 is 4.7 GB (Giga Byte), which is 7
times that of a CD. The data capacity of a
double-layer and single-sided DVD is 8.5

double-layer and single-sided DVD is 8.5
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.

Recording) mode allow the contents to be
programmed or edited.

Interlace format (page 17)
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

Additional Information
Progressive format (page 17)
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 progressive
format.
