VIDEO CD
A compact disc that contains moving
pictures.
The picture data uses the MPEG 1 format,
one of the worldwide standards for 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.
Sound 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 back only
moving pictures and sounds.
• Version 2.0: You can play back high-
resolution still pictures and enjoy PBC
functions.
This system conforms to both versions.
