Playback Control (PBC)
Signals encoded on VIDEO CDs (Version 2.0)

progressive format can reproduce 50 to 60
frames per second by reproducing all scanning
lines (525 lines for the NTSC system, 625 lines
for the PAL system). The overall picture quality
increases and still images, text, and horizontal
lines appear sharper. This format is compatible
with the 525 or 625 progressive format.

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.
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.
