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.
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
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.
Playback Control (PBC)
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.
