VCDs/S-VCDs
With "Video CD" (VCD) and "Super Video CD" (S-VCD) two
compression processes, thus space saving, are designated for
storage of films on CDs. VCDs and S-VCDs exist in the sizes 8 cm
and 12 cm (diameter). Their storage capacity is lower than
that of DVDs. Therefore they offer only a playback duration,
for the Audio and Video stored on them, of 20 minutes (8 cm
format) and/or 74 minutes (12 cm format).
VCDs exist in two versions:
• Only audio and video data can be played back on version
1.1 VCDs/S-VCDs.
• PBC (Playback control) functions are available on version
2.0 VCDs/S-VCDs. In addition, paused images can be dis-
played in high resolution.
Playback Control (PBC)
VCDs/S-VCDs of version 2.0 have Playback Control ("PBC").
This means that a root menu is available on the VCD/S-VCD,
with which various features of the VCD/SVCD can be accessed.
What are titles and chapters?
Titles are the largest units of video and audio data on DVDs;
with many DVDs the (Main) film has the title number 01.
For bonus material (i.e. film trailers, background information
etc.), that is available on many DVDs, current additional title
numbers can be used.
Chapters are the next smaller unit of video and audio data
beneath titles. If the title or titles on a DVD/VCD/S-VCD are
subdivided into chapters, they are assigned numbers that
can be entered to select the chapters directly.
Please note that not all DVDs ...
• are the title or titles (numbered) subdivided into chapters
• Are chapters also indicated as "scenes" (i.e. in the DVD's
main menu)
What are Scart, S-Video, Composite-Video Progressive Scan,
YUV and HDMI?
Scart
Scart refers to a 21-pin, standardised connector over which
the RGB signals, video signals and S-video signals as well as
numerous control and additional signals are transmitted.
S-video
When the DVD player is connected to a television via S-video,
the brightness and colour signals are separated; this achieves
better image sharpness and less "colour noise".
Colour noise refers to the overlaying of the colourful, usually
highly saturated parts of a video image with irregular, varia-
ble flaw patterns.

Composite video
Video signal or FBAS signal; this refers to a video signal that
contains both colour and brightness information.
Progressive scan
Normally TV sets and Video projectors with so called "Half
images" are controlled. This results in clearly visible line struc-
tures. In contrast, progressive scan refers to the supply of full
images (with this DVD player at the YPbPr output), progressive
scan signals can only be processed by playback devices (primarily
large screen televisions, projectors) that offer this feature.
The image quality is significantly better than typical video
signals.
YUV (component video out)
YUV refers to the component signal, which is available with
this device at the YPbPR output in the form of "half images";
as a rule this is the best signal for the control of large screen
televisions and projectors, which can not process Progressive
scan signals. As with RGB video signals, the YUV consists of
three separate video signals:
• the brightness signal "Y" and
• both colour difference signals "Pb/Cb" and "Pr/Cr"
Half images (interlacing) / full images (progressive scanning)
A standard television image consists of 576 visible lines; first
the odd then the even image lines are displayed in alterna-
tion. In other words, one half image is shown at a time. In
this way, only 30 full images (60 half images) can be displayed
per second. This method is referred to as "interlace" format.
Contrary to this with the so called progressive or "Progressive
scan" format all images are shown every time, that is to say
60 full images per second are displayed. This increases the
overall quality of the image; for example paused images
and text appear sharper.
HDMI
HDMI is short for "High Definition Multimedia Interface" and
refers to a 19 contact interface for complete digital transmis-
sion of audio and video data. With its high bandwidth HDMI
handles all known today home electronics digital video and
audio formats. HDMI transmits audio data up to frequencys
of 192 kHz with text widths of up to 24 Bit on up to 8 channels.
Thus not only all of today's image and sound formats intro-
duced into home electronics including HDTV (up to the highest
present resolution of 1080i) are transmitted without loss of
quality but also future formats with yet higher resolutions.
