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
playback function.
Multi‑angle function
Various angles, or viewpoints of the video
camera, for a scene are recorded on some
DVD VIDEOs.
Multilingual function
Several languages for the sound or
subtitles in a picture are recorded on
some DVD VIDEOs.
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 disc is a disc having multiple
sessions, with each segment from Lead-in
to Lead-out regarded as a single session.
Parental Control
A function of the DVD VIDEO 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 (sequential
scanning)
In contrast to the Interlace format, the
progressive format can reproduce 50
60 frames per second by reproducing all
scanning lines (525 lines for the NTSC
system, 625 lines for 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.
