Track
Sections of a picture or a music piece on a CD or VIDEO
CD. Each track is assigned a track number enabling you to
locate the track you want.
VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of the
worldwide standards of digital compression technology.
The picture data is compressed to about 1/140 of its
original size. Consequently, a 12 cm VIDEO CD can
contain up to 74 minutes of moving pictures.
VIDEO CDs also contain compact audio data. Sounds
outside the range of human hearing are compressed while
the sounds we can hear are not compressed. VIDEO CDs
can hold 6 times the audio information of conventional
audio CDs.
There are 2 versions of VIDEO CDs.
• Version 1.1: You can play only moving pictures and
sounds.
• Version 2.0: You can play high-resolution still pictures
and enjoy PBC functions.
This system conforms to both versions.
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.
Multi-angle function (page 43)
Various angles, or viewpoints of the video camera, for a
scene are recorded on some DVDs.
Multilingual function (pages 15, 41, 43)
Several languages for the sound or subtitles in a picture
are recorded on some DVDs.
Parental Control (page 54)
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.
Playback Control (PBC) (page 30)
Signals encoded on VIDEO CDs (Version 2.0) to control
playback.
By using menu screens recorded on VIDEO CDs with PBC
functions, you can enjoy playing simple interactive
programs, programs with search functions, and so on.
