ATRAC3
ATRAC3, which stands lbr Adaptive 'lYanstk}rm Acoustic Coding3, is audio compression
technology that satisfies 1he demand for high sound qualgy and high compression rates.
The AI'RAC3 compression rate is approximately 10 times higher _ban lhat of the Audio
CD, resulting an increased data capacity lbr the media.
"Check-in/Check-Out"
Check-out is to transfer music files from a personal compuler to an external device/media
(such as a Network Walkman). Returning checked-out music files 1{}the same computer is
to check in. (You cannot move checked-out music files to anolher computer.)
You can check out a music file, check it back in, and lben check it out again an infinite
number of times. The SDMI rules provide that up to lbur copies of a music file can be
checked out at one time. OpenMG employs a melhod whereby lhree copies of a song can
be checked out simultaneously, while the fourth copy is maintained as a master on your PC.
Electronic Music Distribution (EMD) service
EMD is a websile that distribules music flies which are available for purchase.
MP3
MP3, which stands tbr MPEG-I Audio Layer3, is a stmMard fbr audio file compression
determined by the Motion Picture Experts Group, an ISO (lnlernational Organization lbr
St3ndardizafion) working group. It enables compression of audio files m about 1/10 of the
data size of a standard compact disc. Since the MP3 encoding algorithm is disclosed, there
are various encoders/decoders that are compliant with this standard, including fi'eeware lbat
is available for no charge. The MP3 standard is therefore widely used in the computer field.
Music Drive
Music Drive is a music database lbr managing audio data on a computer, in Music Drive,
audio files can be managed along wilh such inlbn_ation as artist names, track names, and
CD jacket images, or can be combined and calegorized in different playlists.
OpenMG
Copyright protection technology for the import and mm_agement of musical content from
distribution services or CDs. By using software that are compliant with OpenMG, audio
contents can be encrypled before slorage on a hard disk drive to allow playback of those
audio files on that compuler. OpenMG also prevenls the unauthorized distribution of the
contents via the lnternet or olber networks.
Playlist
A playlist is like a container that can be used 1o hold and calegorize files slored in Music
Drive. For example, by making a "jazz" playlist and then putting your favori|e jazz tracks
into the playlist, you can play all of the tracks repeatedly or check 1hem all out at the same
time.
