■ Component video signal
With the component video signal system, the video signal
is separated into the Y signal for the luminance and the PB
and P
R signals for the chrominance. Color can be
reproduced more faithfully with this system because each
of these signals is independent. The component signal is
also called the “color difference signal” because the
luminance signal is subtracted from the color signal.
■ NTSC (National Television System
Committee)
NTSC is a video signal system (525 lines, 30 frames per
second) used in North America, Central America, a
number of South American countries, and some Asian
countries, including Japan.
■ PAL (Phase Alternating Line)
PAL is a video signal system (625 lines, 25 frames per
second) used in the United Kingdom, much of the rest of
western Europe, several South American countries, some
Middle East and Asian countries, several African
countries, Australia, New Zealand, and other Pacific
island countries.
■ Pan & Scan and Letterbox
In general, DVD Video is produced for viewing on a wide
television screen with an aspect ratio of 16:9. This means
you can now view most material with the intended aspect
ratio on a wide-screen television.
This ratio will not fit on a standard television that has an
aspect ratio of 4:3. Two picture styles, Pan & Scan and
Letterbox, deal with this problem.
• Pan & Scan cuts off the left and right portions of the
picture to fill the screen.
• Letterbox inserts black bands at the top and bottom of
the picture to reproduce an aspect ratio of 16:9.
■ Progressive scan
A method of displaying all scanning lines in a frame at
once, reducing flicker noticeable on a larger screen and
creating a sharp and smooth image.
■ Title, Chapter (DVD Video)
DVD video lets you divide a disc in a big way by titles or a
small way by chapters. Each division is either called a title
number or a chapter number.
