Regions (DVD-Video only)
These associate discs and players with particular
areas of the world. This unit will only play discs
that have compatible region codes. You can find
the region code of your unit by looking on the rear
panel. Some discs are compatible with more than
one region (or all regions).
Sampling frequency
The rate at which sound is measured to be turned
into digital audio data. The higher the rate, the
better the sound quality, but the more digital
information is generated. Standard CD audio has a
sampling frequency of 44.1kHz, which means
44,100 samples (measurements) per second. See
also Digital audio.
Slideshow (DVD, Video CD)
A feature of some DVD discs in which still pictures
recorded on the disc cycle automatically as the
audio is played. See also Browsable pictures.
Super Audio CDs
This is a high audio quality pure audio standard
with more data recorded based on CD standards.
There are three different types of super audio CD
discs, single layer, dual layer and hybrid. Hybrid
discs have the structure of both CD and super
audio CD discs.
Title (DVD-Video only)
A collection of chapters on a DVD-Video disc.
Equivalent to a DVD-Audio group. See also
Chapter and Group.
Track
Audio CDs, Video CDs and DVD-Audio discs all
use tracks to divide up the content of a disc. The
DVD-Video equivalent is called a chapter. See also
Chapter and Group.
MPEG video
The video format used for Video CDs and DVDs.
Video CDs uses the older MPEG-1 standard, while
DVD uses the newer and much better quality
MPEG-2 standard.
Multi-session
A CD-R/RW that contains two or more ‘sessions’.
Each session is a complete recording process, so
each session is read as a complete disc. This player
can only read the first session on a disc.
Optical digital output
A jack that outputs digital audio in the form of
light pulses. Connect components with optical
digital jacks using a special optical cord, available
from good audio dealers.
Packed PCM (DVD-Audio only)
A lossless compression system that enables more
PCM audio to be stored on a DVD-Audio disc than
would otherwise be possible.
PCM (Pulse Code Modulation)
The most common system of encoding digital
audio, found on CDs and DAT. Excellent quality,
but requires a lot of data compared to formats
such as Dolby Digital and MPEG audio. For
compatibility with digital audio recorders (CD, MD
and DAT) and AV amplifiers with digital inputs, this
unit can convert Dolby Digital, DTS and MPEG
audio to PCM. See also Digital audio.
PBC (PlayBack Control) (Video CD only)
A system of navigating a Video CD through on-
screen menus recorded onto the disc. Especially
good for discs that you would normally not watch
from beginning to end all at once—karaoke discs,
for example.
Progressive scan video
Also called non-interlaced video, this method of
displaying a picture updates all the lines in one
pass, resulting in a more stable, flicker-free image
than interlaced video (for a given scanning rate).
See also Interlaced video.
