Film based software, Video
based software
DVDs can be classified as Film based or Video
based software. Film based DVDs contain the
same images (24 frames per second) that are
shown at movie theaters. Video based DVDs,
such as television dramas or sit-coms, displays
images at 30 frames (or 60 fields) per second.
Index (CD) / Video Index (VIDEO
CD)
A number that divides a track into sections to
easily locate the point you want on a VIDEO CD
or a CD. Depending on the disc, no indexes may
be recorded.
Interlace format
(Interlaced scanning)
The Interlace format is the NTSC standard
method for displaying TV images at 30 frames
per second. Each frame is scanned twice-
alternately between the even numbered scanning
lines and then odd numbered scanning lines, at
60 times per second.
Menu Playback
Playback using the menu screens recorded on
VIDEO CDs with PBC functions. You can enjoy
simple interactive software using the menu
palyback function.
Multi-angle function
Various angles, or viewpoints of the video
camera, for a scene are recorded on some DVDs.
Multilingual function
Several languages for the sound or subtitles in a
picture are recorded on some DVDs.
Multi Session
This is a recording method that enables adding
of data using the Track-At-Once method.
Conventional CDs begin at a CD control area
called the Lead-in and end at an area called
Lead-out. A Multi Session CD is a CD having
multiple sessions, with each segment from
Lead-in to Lead-out regarded as a single session.
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.
This system conforms to Version 1.1 and
Version 2.0 of VIDEO CD standards. You can
enjoy two kinds of playback depending on the
disc type.
VIDEO CDs without PBC functions
(Version. 1.1 discs)
Enjoy video playback (moving pictures) as well
as music.
VIDEO CDs with PBC functions
(Version. 2.0 discs)
Play 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 unit is compatible with 525
progressive format.
