Glossary

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

 (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.
