ID3
ID3 is information (such as the
track name or artist name) that is
recorded in an MP3 file. The ID3
tag is used by this unit to display
track information for MP3 files.
Internet
A communication network linking
computers around the world. The
Internet supports many services,
including email and search engines.
Internet Service Provider
A company that offers connection
service to the Internet.
IP address
IP addresses usually comprise
four groups of up to three digits
each, separated by a period (such
as 192.168.239.1). All devices on a
network must have an IP address.
ISO9660
A standard of the International
Organization for Standardization
(ISO) that defines the file system of
CD-ROM media.
LAN
Abbreviation of Local Area
Network.
LAN is a general name for
networks set up for communication
among devices including
computers, printers, and fax
machines in relatively small areas
such as offices or buildings.
Linear PCM
Linear Pulse Code modulation,
a digital, non-compression audio
coding system used in this unit for
recording at 16 bits and a sampling
rate of 44.1 kHz (same as the
standard for audio CDs).
MP3
Abbreviation of MPEG-1 Audio
Layer3. It is a standard for audio
file compression determined by the
MPEG (Motion Picture Experts
Group), an ISO (International
Organization for Standardization)
working group. It enables
compression of audio files to 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. The MP3 standard
is therefore widely used in the
computer field.
MSC
MSC refers to the USB Mass
Storage Class in this unit. MSC is
a data transfer protocol defined by
the USB Implementers Forum for
the transfer of data via the USB to
external devices. It is used in USB
hard disks and USB memories, etc.
MTP
Abbreviation for Media Transfer
Protocol.
MTP is a data transfer technology
developed by Microsoft
Corporation. This protocol allows
you to transfer image data, audio
data, video data, etc. to compatible
portable devices.
Proxy
A program or a server that provides
Internet access to computers within
a firewall or quicker downloading
of web pages.
Router
A device that bridges networks,
converting the protocols and
addresses of each network.
Recently, dial-up routers for
connecting to ISDN lines and
broadband routers for ADSL
and CATV networks have been
introduced. The term “router”
by itself may refer to any of these
devices.
Sampling frequency
When audio sources are converted
from analog to digital data, they
must be changed into numbers
(digitized). This process is called
sampling, and the sampling
frequency refers to the number of
times per second that the signals
are measured for the recording.
Music CDs are sampled at 44,100
times per second, so the sampling
frequency is expressed as 44.1 kHz.
Generally, the higher the sampling
frequency, the higher the fidelity of
the recording.
USB storage
In this manual, USB storage refers
to a mass storage device that
supports the USB Mass Storage
Class standard. These devices,
such as a USB audio player, can be
connected to the USB jack on the
unit or a computer and used as a
removable mass storage device.
VAIO Media
VAIO Media is home networking
software that is provided on Sony
VAIO computers. A computer must
have VAIO Media Version 4.1 or
later to be connected to this unit.
WAV
WAV is a file format developed
by Microsoft Corporation and
IBM Corporation for the storage
of digital audio data. A variant
of RIFF (Resource Interchange
File Format), WAV is simply a
container format that can be
used to store data in a variety of
configurations, including Linear
PCM.
WMA
Abbreviation of Windows Media
Audio. WMA is the audio
compression technology developed
by Microsoft Corporation that
allows audio files to be compressed
to about 1/22 of the data size of a
standard compact disc.
