Glossary 
 
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 and digital audio 
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.   
DVB-ASI (Digital Video Broadcasting 
- Asynchronous Serial Interface)   
This is the standard interface in DVB (Digital 
Video Broadcasting: European Digital 
Broadcasting standardization organization) and 
used in MPEG CODEC most commonly. It is the 
asynchronous serial interface and standardized 
in ETSI 101 891.   
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.  It basically converts 
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. 
H.264 
This is one of the video compression coding 
systems standardized in ITU (International 
Telecommunication Union) in May, 2003. It is 
also standardized as a part of MPEG-4 (MPEG-4 
part 10 Advanced Video Coding) in ISO 
(International Organization for Standard). 
Therefore, it is commonly called H.264/MPEG-4 
AVC or H.264/AVC, showing both of parties. 
This technology is used for the various 
applications from the low bit rate and low 
resolution like the mobile TV to the high bit rate, 
high resolution like HDTV. It is improved that the 
data capacity is half comparing MPEG-2 used 
wide spread. 
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
