VIDEO CD
A compact disc that contains moving pictures.
The picture data uses the MPEG 1 format, one of
a worldwide standard 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 sounds we can hear are not
compressed. VIDEO CDs can hold six times the
audio information of conventional audio CDs.
There are two 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.
