ATRAC3
ATRAE%, which stands for Adaptive Transform Acoustic Coding3. is audio compression technology
that satisfies the demand for high sound quality and high compression rates.
The ATRAC3 compression rate is approximately IO times higher than that of the Audio CD, resulting
an
increased data capacity for the media.
Bit rate
Indicates the data amount per second. The rate is reflected in bps (bit per second).
III
this tmit. the bit rate for recording an audio CD or converting MP3 and WAV format audio files into
ATRAC? format can he chosen from I32 kbps/lOSkbps, IO5 kbps means IO.5000 bits of information
per second, If the bit rate
IS
large, that means a large amount of information is used to play music.
Comparing music of the same format, a I32 kbps data offers better somld quality than 105 kbps data.
However, audio files in formats ?uch as MP3 have different encoding methods, and thus sound quality
cannot be determined by <imply comparing the bit rate.
Check-In/Check-Out
Check-Out is to transfer music files from your unit to an external device/media (such as Network
Walkman), Returning Checked-Out music files to the same unit is to Check-In. (You cannot move
Checked-Out music files to another device/media.)
You
cm
Check-Out a music file. check it hack in, and then check it out again an infinite number of
times, The SDMI rules provide that up to four copies of a music file can be Checked-Out at one time.
OpenMCi employs a method wherehy three copies of a song can be Checked-Out simultaneously, while
the fourth copy is maintained a$ a "master" on your unit. If three copies of the same song are Checked-
Out at a given time, one copy of the
$ong
needs to be Checked-In to the unit in order to create an
additional Check-Out.
Import
Transfers audio file\ stored
on
"MG Memory Stick" into this unit. The imported audio files are stored
automatically to the Album 001 in the Folder 001
on
the hard disc drive.
MagicGate
Copyright protection technology that consists of authentication and encryption technology.
Authentication ensures that protected content is transferred only between compliant devices and media,
and that protected content is recorded and transferred in an encrypted format to prevent unauthorized
copying or playback.
Note
MAGICGATE
is fermino/ogy denoting the copyrightprofeclion
system deve/oped by Sony /t does not
guarantee conversion among other media.
"MagicGate
Memory Stick"
A compact IC recording media "Memo1-y Stick" equipped with "Magi&ate"
copyright protection
technology. You can record or play data. such as music, that requires copyright protection only by using
a "Magi&ate
Memory Stick'. with "MagicGate" compatible equipment (e.g., Network Walkman).
"MagicGate Memory Stick' can be used to record any other kind of digital data with any other
"Memory Stick" compatible equipment.
.'MagicGate Memory Stick.' is distinguished by the "MG" and "MAGIC GATE" logos.
