AES/EBU
This is the standard of the professional digital
audio signals and standardized by AES and EBU.
ANSI adopts it too.
Alarm Log
Record of errors that have occurred on devices
and communication lines
BNC (Bayonet Neill Concelman)
Type of coaxial connector whose characteristic
impedance is 75 Ω . A locking system called a
bayonet lock is used, ensuring cables are easy
to connect and remove, and secure connections.
The connector is compact and lightweight and
has a frequency range compatible with the high
frequency of 4 GHz, so it can be used for
measuring instruments
equipment.
Browser
General name for programs that support users
who want to select desired options from
available options. Using a browser, a user can
trace links on the Internet to access such
multimedia information as text, audio, and video
by simply using a pointing device (e.g., mouse)
to select items.
DCE (Data Circuit terminating Equipment)
Data circuit terminating equipment. DCE is a
term from ITU-T. Similar to modems and DSUs,
it changes signals to waveform that are suitable
for their transmission routes.
DHCP (Dynamic Host Configuration Protocol)
This is the protocol to assign IP address
dynamically when startup and to release it when
shutdown. The IP address prepared by DHCP
server is assigned.
DTE (Data Terminating Equipment)
Data terminating equipment. It is one kind of
terminal equipment (e.g., PC). DTE is a term
from ITU-T and is paired with DCE.
Embedded Audio
It is the scheme to embed (multiplex)
AES/EBU digital audio signals in the auxiliary
data area (blanking area) of the serial digital
signal.

FG (Frame Ground)
Ground for a cabinet
Flow Control
Procedure for controlling the flow of data
between two devices. Its purpose is to prevent
data loss when the device buffer becomes full.
Gateway
Equipment that connects network systems that
use different protocols.
one protocol into another to support operation
between two networks. In a broader sense, a
gateway sometimes means a device that
transfers information between any two networks.
HD-SDI (High Definition television – Serial
Digital Interface)
HD-SDI is the serial digital interface to
transmit HD (High Definition) video signal,
which transmission rate is 1.485 Gbps. It can
transmit multiplexing HD video signal, PCM
audio signal and data signal like time stamp.
HTTP (Hyper Text Transfer Protocol)
Protocol used for sending and receiving files
and other data between a WWW server and
WWW browser
Hub
Concentrator required for using 10BASE-T or
100BASE-TX as a local area network (LAN)
standard. Twisted-pair cables are used to
connect hubs. A high-speed hub conforms to
100BASE-TX, and a switching hub has switching
functions.
IP (Internet Protocol)
Protocol used between host computers to
transfer packets over all of the Internet. The
codes that identify the destinations and senders
in packet transfers are called IP addresses. An
IP address is a 32-bit code that can identify a
network and host in the network. A unique IP
address must be allocated to each hosts that
communicates on the Internet.
IP Address
Code used for identifying a node (e.g., PC)
operating using TCP/IP. This 32-bit number is
