En
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 beginning to end all
at once—karaoke discs, for example.
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. See also Digital audio.
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).
S1 S-video output
This S-video signal format includes aspect
ratio information (4:3 or 16:9) within the video
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.
Widescreen TVs which are compatible with
S2 S-video automatically switch to the
appropriate mode according to the signal.
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.
