English
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.
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 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.
Regions (DVD only)
These associate discs and players with
particular areas of the world. This system
will only play discs that have compatible
region codes. You can find the region code
of your system 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.
Title (DVD only)
A collection of chapters on a DVD disc. See
also Chapter.
