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).
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 or Windows
Media Player for Windows XP.
