stands for three front and two rear surround sound
channels, the "1" for the bass sound chanel.

17.4 MP3, WMA, JPEG, DivX andMPEG

MP3

MP3 denotes a process and/or format developed
by the Fraunhofer Institute for the compression of
audio data. In the MP3 format compressed music
pieces are only a fraction of their original size,
which, for example, on CD-Rs/CD-RWs allows for
storage of a considerably greater volume of music
than on commercially available audio CDs, on
which audio data is stored in the CDA format.
The structure of an MP3-CD can, for example, appear
as follows, if the MP3 data is stored in files:

WMA

WMA ("Windows® Media Audio") is a data format
developed by Microsoft® for audio data.

JPEG

JPEG ("Joint Photographics Expert Group") denotes
a wide spread graphic format, developed by the
organization with the same name, with which image
data of the colour and grey scales are compressed.

DivX

DivX is a coding format for videos and multimedia
data, invented by the DivX Networks, Inc company.

MPEG

MPEG ("Moving Picture Experts Group") refers to
a video compression format.
17.5 What are files?
As opposed to audio CDs the title on a CD-R/CD-RW
with MP3-, WMA- or JPEG data can be stored in
files, for example, in order to file titles from different
genres.
