Additional Information
PureCinema (DVD-Video only)
Video on a DVD discs may be either video
material (originally shot on video) or film
material (originally shot on film). Video material
has a frame rate of 30 frames/sec.(NTSC),
compared with 24 frames/sec. for film. This
player converts film material to 60 frames/sec.
(in progressive scan mode). PureCinema adjusts
the picture so that it matches more closely the
picture quality of a cinema screen.
You can see whether video on a DVD disc is film
or video material by displaying the video
transmission rate (see
page 34
). If a hash mark
(#) appears above the transmission rate
display, it is film material.
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, Super VCD/Video CD)
A feature of some DVD discs in which still
pictures recorded on the disc cycle automati-
cally as the audio is played. See also

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, Super VCDs/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 Super VCDs/Video
CDs and DVDs. Super VCDs/Video CDs uses
the older MPEG-1 standard, while DVD uses the
newer and much better quality MPEG-2 stan-
dard.
Multi-session
A CD-R/RW that contains two or more ‘ses-
sions’. 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)
(Super VCD/Video CD only)
A system of navigating a Super VCD/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
