VIDEO CDs with PBC functions
(Version. 2.0 discs)
Play back interactive software using menu
screens displayed on the TV screen (PBC
Playback), in addition to the video playback
function of Version 1.1 discs. Moreover, you
can play high-resolution still pictures, if they are
included on the disc.
Progressive format
(sequential scanning)
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 VIDEO according to the sales region.
Each region code is shown on the unit as well as
on the disc packaging. The system can play back
the discs that match its region code. The system
can also play back discs with the “ ” mark.
Even when the region code is not shown on the
DVD VIDEO, the region limit may still be
activated.
Scene
On a VIDEO CD with PBC functions, the menu
screens, moving pictures and still pictures are
divided into sections called “scenes”. Each
scene is assigned a scene number enabling you
to locate the scene you want.
Title
The longest section of a picture or a music piece
on a DVD VIDEO; a movie, etc., for a picture
piece on video software; or an album, etc., for a
music piece on audio software. Each title is
assigned a title number enabling you to locate
the title you want.
Track
Sections of a picture or a music piece on an
AUDIO CD, VIDEO CD, DATA CD or DATA
DVD. Each track is assigned a track number
enabling you to locate the track you want.
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.
