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). See also page 11.
S1 S-video output
This S-video signal format includes aspect
ratio information (4:3 or 16:9) within the
video signal. TVs which are compatible with
S1 S-video automatically switch aspect ratio
according to the signal. See also page 53.
S2 S-video output
S2 is an enhanced version of S-video which,
in addition to aspect ratio information,
contains letterbox / pan & scan information.
Widescreen TVs which are compatible with
S2 S-video automatically switch aspect ratio
according to the signal. See also page 53.
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 fre-
quency of 44.1kHz, which means 44,100
samples (measurements) per second. See
also Digital audio.
Slidshow (DVD, Video CD/Super VCD)
A feature of some DVD discs in which still
pictures recorded on the disc cycle automati-
cally as the audio is played. See also
Browsable Picture.
Super Audio CD (SACD)
Super Audio CD is a high quality audio disc
format that can accomodate high sampling
rate stereo and multi-channel audio, as well
as conventional CD audio all on the same
disc.
MPEG audio
An audio format used on Video CDs/Super
VCDs and some DVD discs. This unit can
convert MPEG audio to PCM format for wider
compatibility with digital recorders and AV
amplifiers. See also PCM.
MPEG video
The video format used for Video CDs/Super
VCDs and DVDs. Video CD/Super VCD uses
the older MPEG-1 standard, while DVD uses
the newer and much better quality MPEG-2
standard.
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 possi-
ble.
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/Super
VCD only)
A system of navigating a Video CD/Super
VCD through on-screen menus recorded
onto the disc. Especially good for discs that
you would normally not watch from begin-
ning 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. See also page 19.
