Additional Information
Bit rate (page 42)
Value indicating the amount of video data compressed in
a DVD per second. The unit is Mbps (Mega bit per
second). 1 Mbps indicates that the data per second is
1,000,000 bits. The higher the bit rate, the larger the
amount of data. However, this does not always mean that
you can get higher quality pictures.
Chapter (page 7)
Sections of a picture or a music piece on a DVD that are
smaller than titles. A title is composed of several chapters.
Each chapter is assigned a chapter number enabling you
to locate the chapter you want.
Dolby Digital (pages 12, 61)
Digital audio compression technology developed by
Dolby Laboratories. This technology conforms to 5.1-
channel surround sound. The rear channel is stereo and
there is a discrete subwoofer channel in this format.
Dolby Digital provides the same 5.1 discrete channels of
high quality digital audio found in Dolby Digital cinema
audio systems. Good channel separation is realized
because all of the channel data is recorded discretely and
processed in digital.
Dolby Pro Logic (pages 12, 61)
Audio signal processing technology that Dolby
Laboratories developed for surround sound. When the
input signal contains a surround component, the Pro
Logic process outputs the front, center and rear signals.
The rear channel is monaural.
DTS (pages 12, 61)
Digital audio compression technology that Digital Theater
Systems, Inc. developed. This technology conforms to 5.1-
channel surround. The rear channel is stereo and there is
a discrete subwoofer channel in this format. DTS provides
the same 5.1 discrete channels of high quality digital
audio. Good channel separation is realized because all of
the channel data is recorded discretely and processed in
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 dual-layer and single-sided DVD is 8.5
GB, a single-layer and double-sided DVD is 9.4 GB, and a
dual-layer and double-sided DVD is 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 a variable rate coding
technology that changes the data to be allocated according
to the status of the picture.
Audio data is recorded in Dolby Digital or DTS, as well as
in PCM, 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.
Film based software (page 63)
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.
Interlace format (page 63)
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 (page 37)
Various angles for the scene (viewpoints of the video
camera) are recorded on some DVDs.
Multilingual function (pages 16, 37, 53)
Several languages for the audio track or subtitles in a
picture are recorded on some DVDs.
Parental Control (page 43, 57)
A function of the DVD used to limit playback of the disc
according to the age of the user and 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.
