Explanation terms
A
AES (Advanced Encryption Standard)
This is a next generation standard encryption
method replacing the current DES and 3DES, and
because of its high security it is expected to be
applied widely to wireless LANs in the future. It
uses the “Rijndael” algorithm developed by two
Belgian cryptographers to divide the data into
blocks of fi xed lengths and encrypt each block.
It supports data lengths of 128, 192 and 256 bits
and key lengths of 128, 192 and 256 bits as well,
offering extremely high encryption security.
B
Bit rate
This expresses the read amount per 1 second of
video/audio data recorded in a disc.
D
DLNA
DLNA and DLNA CERTIFIED are trademarks and/
or service marks of Digital Living Network Alliance.
Some contents may not be compatible with other
DLNA CERTIFIED™ products.
F
Finalize
This is processing that enables playing back of disc
of CD, which was recorded using a recorder, by
other players.
I
IEEE 802.11b
This is one wireless LAN standard set by the 802
working group that establishes LAN technology
standards at the IEEE (Institute of Electrical and
Electronics Engineers) of the United States. It
uses the 2.4 GHz band usable freely without
a radio frequency license (ISM band), enabling
communications at a maximum speed of 11 Mbps.
• The value indicated above is the maximum
theoretical value for the wireless LAN standard,
and does not indicate the actual data transfer rate.
IEEE 802.11g
This is another wireless LAN standard set by the
802 working group that establishes LAN technology
standards at the IEEE (Institute of Electrical and
Electronics Engineers) of the United States, and
is compatible with IEEE 802.11b. It also uses the
2.4 GHz band, but enables communications at a
maximum speed of 54 Mbps.
• The value indicated above is the maximum
theoretical value for the wireless LAN standard,
and does not indicate the actual data transfer rate.
M
MP3 (MPEG Audio Layer-3)
This is an internationally standardized audio data
compression scheme, using the “MPEG-1” video
compression standard. It compresses the data
volume to about one eleventh its original size while
maintaining sound quality equivalent to a music CD.
MPEG (Moving Picture Experts Group), MPEG-2,
MPEG-4
These are the names for digital compression format
standards used for the encoding of video and audio.
Video standards include “MPEG-1 Video”, “MPEG-
2 Video”, “MPEG-4 Visual”, “MPEG-4 AVC”. Audio
standards include “MPEG-1 Audio”, “MPEG-2
Audio”, “MPEG-4 AAC”.
N
Network Names
(SSID: Security Set Identifi er)
When forming wireless LAN networks, groups are
formed to prevent interference, data theft, etc.
This grouping is done by “SSID” or “Security Set
Identifi ers”. For further security, a WEP key is set
and signal transfer is not possible unless the SSID
and WEP key match.
P
Protection circuit
This is a function to prevent damage to components
within the power supply when an abnormality
such as an overload, excess voltage occurs or
temperature for any reason.
In this unit, the power turns off suddenly.
S
Sampling frequency
Sampling involves taking a reading of a sound wave
(analog signal) at regular intervals and expressing
the height of the wave at each reading in digitized
format (producing a digital signal).
The number of readings taken in one second is
called the “sampling frequency”. The larger the
value, the closer the reproduced sound is to the
original.
Speaker impedance
This is an AC resistance value, indicated in Ω
(ohms). Greater power can be obtained with this
value smaller.
T
TKIP (Temporal Key Integrity Protocol)
This is a network key used for WPA. The encryption
algorithm is RC4, the same as for WEP, but the
security level is increased by changing the network
key used for encryption for each packet.

W
WEP Key (Network Key)
This is key information used for encrypting data
when conducting data transfer. On this unit, the
same WEP key is used for data encryption and
decryption, so the same WEP key must be set on
both devices in order for communications to be
established between them.
Wi-Fi®
Wi-Fi Certifi cation assures tested and proven
interoperability by the Wi-Fi Alliance, a group
certifying interoperability among wireless LAN

Windows Media DRM
This is a copyright protection technology developed
by Microsoft.
Content providers are using the digital rights
management technology for Windows Media
contained in this device (WM-DRM) to protect
the integrity of their content (Secure Content) so
that their intellectual property, including copyright,
in such content is not misappropriated. This
device uses WM-DRM software to play Secure
Content (WM-DRM Software). If the security of
the WM-DRM Software in this device has been
compromised, owners of Secure Content (Secure
Content Owners) may request that Microsoft
revoke the WM-DRM Software’s right to acquire
new licenses to copy, display and/or play Secure
Content. Revocation does not alter the WM-DRM
Software’s ability to play unprotected content.
A list of revoked WM-DRM Software is sent to
your device whenever you download a license for
Secure Content from the Internet or from a PC.
Microsoft may, in conjunction with such license,
also download revocation list onto your device on
behalf of Secure Content Owners.
Windows Media Player Ver. 11
This is a media player distributed free of charge by
Microsoft Corporation.
It can be used to play playlists created with
Windows Media Player Ver. 11 as well as fi les in
such formats as WMA, DRM WMA, MP3 and WAV.
WMA (Windows Media Audio)
This is audio compression technology developed by
Microsoft Corporation.
WMA data can be encoded using Windows Media®
Player Ver.7, 7.1, Windows Media®Player
for Windows® XP and Windows Media® Player 9
Series.
To encode WMA fi les, only use applications
authorized by Microsoft Corporation. If you use
an unauthorized application, the fi le may not work
properly.
