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. 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.
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 Interlace 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 player
is compatible with the 480 progressive
format.
The picture data uses the MPEG 2 format,
one of the worldwide standards of digital
compression technology. The picture data is
compressed to about 1/40 of its original size.
The DVD also uses the variable rate coding
technology that changes the data to be
allocated according to the status of the
picture.
The audio data is recorded in Dolby Digital
as well as in PCM, allowing you to enjoy
more real audio presence.
Furthermore, various advanced functions
such as the multi-angle, multilingual, and
Parental Control functions are provided with
the DVD.
