Progressive format
Compared to the Interlace format that
alternately shows every other line of an image
(field) to create one frame, the Progressive
format shows the entire image at once as a
single frame. This means that while the
Interface format can show 30 frames (60 fields)
in one second, the Progressive format can show
60 frames in one second. The overall picture
quality increases and still images, text, and
horizontal lines appear sharper. This system is
compatible with 525 progressive format.
Region Code
This system is used to protect copyrights.
A region code is allocated on each DVD
system or DVD disc according to the sales
region. Each region code is shown on the
system as well as on the disc packaging. The
system can play the discs that match its region
code. The system can also play discs with the
" " mark. Even when the region code is not
ALL
shown on the DVD, the region limit may still
be activated.

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 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.
