Explanation of terms

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 ﬁxed 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.

AirPlay

AirPlay sends (plays) contents recorded in iTunes

or on an iPhone/iPod touch/iPad to a compatible

device via the network.

App Store

App Store is a site that sells application software

for such devices as the iPhone or iPod Touch, and

is operated by Apple Inc.

Bit rate

This expresses the read amount per 1 second of

video/audio data recorded in a disc. A larger number

means higher sound quality, but also means a larger

ﬁle size.

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.

FLAC

FLAC stands for Free lossless Audio Codec, and is a

lossless free audio ﬁle format. Lossless means that

the audio is compressed without any loss in quality.

The FLAC license is as shown below.

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.

iTunes

iTunes is the name of the multimedia player

provided by Apple Inc. It enables management

and playback of multimedia contents including

music and movies. iTunes supports many main ﬁle

formats including AAC, WAV, and MP3.

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”.

Network Names

(SSID: Security Set Identiﬁer)

When forming wireless LAN networks, groups are

formed to prevent interference, data theft, etc.

This grouping is done by “SSID” or “Security Set

Identiﬁers”. For further security, a WEP key is set

and signal transfer is not possible unless the SSID

and WEP key match.

Protection Circuit

This is a function to prevent damage to devices

within the power supply when an abnormality

such as an overload, excess voltage occurs or

temperature for any reason.

In this unit, the power indicator blinks and the unit

enters standby mode when an abnormality occurs.

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.

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.
