Glossary —Continued
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.
PBC (PlayBack Control) (Video CD only)
A system of navigating a Video CD through onscreen
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.
For compatibility with digital audio recorders (CD, MD,
and DAT) and AV amplifiers with digital inputs, this unit
can convert Dolby Digital, and DTS to PCM. See also
“Digital audio.”
Progressive scan video
All the lines that make up a video picture are updated in
one pass (compared to interlace which takes two passes
to update the whole picture).
RIHD *1 (Remote Interactive over HDMI)
Onkyo’s implementation of CEC (Con-
sumer Electronics Control), which allows integrated sys-
tem control over HDMI and is part of the HDMI
standard.
Regions (DVD-Video only)
These associate discs and players with particular areas of
the world. This unit will only play discs that have com-
patible 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).
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 gener-
ated. Standard CD audio has a sampling frequency of
44.1kHz, which means 44,100 samples (measurements)
per second. See also “Digital audio.”
WMA
WMA is short for Windows Media Audio and refers to
an audio compression technology developed by
Microsoft Corporation. WMA data can be encoded by
using Windows Media Player version 8.
