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 About progressive scan video on page 24.
Regions (DVD-Video only)
These associate discs and players with partic-
ular 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).
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.
S2 S-video output
S2 is an enhanced version of S-video which, in
addition to aspect ratio information, contains
letterbox / pan & scan information. Wide-
screen TVs which are compatible with S2 S-
video automatically switch aspect ratio
according to the signal.

En
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. Stan-
dard 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/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 Brows-
able Picture.
Super Audio CD (SACD)
Super Audio CD is a high quality audio disc
format that can accommodate high sampling
rate stereo and multi-channel audio, as well
as conventional CD audio all on the same
disc.
