Parental Control
A function of the DVD to limit playback of the
disc by the age of the users according to the
limitation level in each country/region. The
limitation varies from disc to disc; when it is
activated, playback is completely prohibited,
violent scenes are skipped or replaced with other
scenes and so on.
Playback Control (PBC)
Signals encoded on VIDEO CDs (Version 2.0)
to control playback. By using menu screens
recorded on VIDEO CDs with PBC functions,
you can enjoy playing simple interactive
programs, programs with search functions, and
so on.
This system conforms to Ver. 1.1 and Ver. 2.0 of
VIDEO CD standards. You can enjoy two kinds
of playback depending on the disc type.
VIDEO CDs without PBC functions
(Ver. 1.1 discs)
Enjoy video playback (moving pictures) as well
as music.
VIDEO CDs with PBC functions
(Ver. 2.0 discs)
Play interactive software using menu screens
displayed on the TV screen (PBC Playback), in
addition to the video playback functions of Ver.
1.1 discs. Moreover, you can play high-
resolution still pictures, if they are included on
the disc.
Progressive format
(sequential scanning)
In contrast to the Interlace format, the
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.
Region Code
This system is used to protect copyrights. A
region number 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 shown on the DVD, the
region limit may still be activated.
Title

piece on a DVD; 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.
