Dynamic range
The difference between the quietest and loud-
est sounds possible in an audio signal (with-
out distorting or getting lost in noise).
Dolby Digital and DTS soundtracks are capa-
ble of a very wide dynamic range, delivering
dramatic cinema-like effects.
EXIF (Exchangeable Image File)
A file format developed by Fuji Photo Film
for digital still cameras. Digital cameras from
various manufacturers use this compressed
file format which carries date, time and
thumbnail information, as well as the picture
data.
File extension
A tag added to the end of a filename to indi-
cate the type of file. For example, “.mp3”
indicates an MP3 file.
ISO 9660 format
International standard for the volume and file
structure of CD-ROM discs.
JPEG
A file format used for still images, such as
photographs and illustrations. JPEG files are
identified by the file extension “.jpg” or
“.JPG”. Most digital cameras use this format.
MP3
MP3 (MPEG1 audio layer 3) is a compressed
audio file format. Files are recognized by
their file extension “.mp3” or “.MP3”.
MPEG audio
An audio format used on Video CDs and
some DVD discs. This unit can convert
MPEG audio to PCM format for wider com-
patibility with digital recorders and AV
amplifiers. See also “PCM (Pulse Code Mod-
ulation)”.
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
on-screen menus recorded onto the disc.
Especially good for discs that you would nor-
mally 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. For compatibility with digital audio
recorders (CD, MD and DAT) and AV ampli-
fiers with digital inputs, this unit can convert
Dolby Digital, DTS and MPEG audio to
PCM. See also “Digital audio”.
Regions (DVD-Video only)
These associate discs and players with partic-
ular 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).
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”.
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.
