Bit rate
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 is, the
larger the amount of data. However, this
does not always mean that you can get
higher quality pictures.
Chapter
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
This sound format for movie theaters is more
advanced than Dolby Pro Logic Surround. In
this format, the rear speakers output stereo
sound with an expanded frequency range
and a subwoofer channel for deep bass is
independently provided. This format is also
called "5.1” because the subwoofer channel
is counted as 0.1 channel (since it functions
only when a deep bass effect is needed). All
six channels in this format are recorded
separately to realize superior channel
separation. Further more, since all the
signals are processed digitally, less signal
degradation occurs.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround,
Dolby Pro Logic Surround produces four
channels from two-channel sound.
Compared with the former Dolby Surround
system, Dolby Pro Logic Surround
reproduces left-to-right panning more
naturally and localizes sounds more
precisely. To take full advantage of Dolby Pro
Logic Surround, you should have one pair of
rear speakers and a center speaker. The rear
speakers output monaural sound.
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 real audio presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided with
the DVD.
MPEG AUDIO
International standard coding system 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.
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.
