17. Glossary/Index

What are DVDs, VCDs and S-VCDs?

DVD stands for "Digital Versatile Disc". They are used to
store audio and video data. They are available in the
formats 8 cm and 12 cm (diameter) DVDs offer a signifi-
cantly higher storage capacity than CD-Rs/CD-RWs – a
playback duration of the stored audio and video data of
up to eight hours.
VCDs/S-VCDs
"Video-CD" (VCD) and "Super Video-CD" (S-VCD) define
two processes that save storage space by compressed
storage of films on CDs. VCDs and S-VCDs are available
in the formats 8 cm and 12 cm (diameter). Their storage
capacity is significantly lower than that of DVDs. Conse-
quently, the 8 cm format provides a storage capacity for
a playback duration of 20 minutes. and the 12 cm format
for 74 minutes.
VCDs are available in two versions:
• Version 1.1 VCDs/S-VCDs will only playback audio and
video data.
• Version 2.0 VCDs/S-VCDs features PBC (Playback Control)
functions; still frames can be reproduced in a high resolu-
tion.

Playback Control (PBC)

Version 2.0 VCDs/S-VCDs feature Playback Control
("PBC"). A main menu is available on the VCD/S-VCD to
operate the different functions of the VCD/S-VCD.

What are title and chapter?

Titles are the largest video and audio units on DVDs.
On many DVDs the (main) film has the title number 01.
Further title numbers can be assigned to bonus mate-
rial (e.g. film trailers, background information, etc) on
many DVDs.
Chapters are the next smallest video and audio units be-
low titles. If the title(s) of a DVD/VCD/S-VCD is/are divided
into chapters, then these are assigned numbers which can
be entered for direct access to the given chapter.
Please note that not all DVDs ...
• feature title(s) subdivided into (numbered) chapters,
• and that chapters may also be designed as "scenes" (e.g.
in the main menu of DVDs)

What are SCART, S-Video, Composite-Video
Progressive Scan and YUV?
Scart
SCART defines a 21-pin, standard plug connection to
transmit RGB signals, video signals and S-Video signals,
as well as a number of other control and extra signals.
S-Video
Connecting the DVD Player to a television by way of S-
Video separates brightness and colour signals to achieve
higher picture sharpness and diminish so-called "coloured
noise" caused by the superimposition of the coloured,
usually intensely saturated, parts of a video picture with
an irregular, restless disturbance structure.
Composite-Video
A video signal or FBAS signal where the video signal con-
tains both colour and brightness information.
Progressive Scan
Normally, televisions and video projectors are controlled
by half pictures or so-called "fields". This produces clearly
visible line structures. Progressive Scan, on the other hand,
defines the output of full pictures or so-called '"frames"
(with this DVD Player at the YPbPr output). Progressive
Scan signals can only be processed by appropriate play-
back units (primarily large-format television, projectors).
Compared with conventional video signals, the picture
quality is significantly enhanced.
YUV (Component Video Out)
YUV defines the component signal supplied by this unit
to the YPbPr output in the form of half-pictures or so-
called "fields". Normally, this is the best signal for con-
trolling large-format televisions and projectors which
cannot process Progressive- Scan signals. As with RGB
video transmission, YUV is composed of three separate
video signals:
• the brightness signal "Y" and
• the two colour differentiation signals "U" and "V".

Fields (Interlace)/Frames (Progressive Scan)

A standard television picture is composed of 576 visible
lines; all odd lines are first shown followed, in alterna-
tion, by all even lines, i.e. half-picture or field. Conse-
quently, only 30 full pictures or frames (60 fields) can
be displayed per second. This method is known as the
"Interlace" format.
