Additional Information
MP3
MP3 (MPEG1 audio layer 3) is a compressed audio
file format. Files are recognized by their file
extension ".mp3" or ".MP3". See also pages 8–9.
MPEG audio
An audio format used on Video CDs 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 and DVDs.
Video CD 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 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.
PQLS (Precision Quartz Lock System)
[rate control]
Technology for high-precision transmission
of digital audio over the i.LINK interface
enabling jitterless digital-to-analog conver-
sion using a precision quartz in the rate
control-compatible receiver.
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 pages 20, 58.
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 9.
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 S-Video Out on page 59.
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 automati-
cally switch aspect ratio according to the signal.
See also S-Video Out on page 59.
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.
Slidshow (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 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.
