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

 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
