Glossary 
 
AES/EBU 
AES (Audio Engineering Society) and EBU 
(European Broadcasting Union) standardized 
for the professional digital audio I/O (IEC-60958 
TYPE-1.) It was applied to ANSI (American 
National Standard Institute) too. 
Alarm Log 
A record of errors occurred on devices and 
communication lines.
 
Ancillary Data 
Transmitted kinds of data located in the 
blanking area of digital video interface (e.g., 
audio data and time code data.) 
ARP (Address Resolution Protocol) 
A protocol that is used to acquire the MAC 
address of the transmission destination of 
Ethernet frames. This protocol uses an IP 
address to acquire the MAC address. If the MAC 
address of the transmission destination of IP 
packets is unknown, an ARP packet requesting 
the MAC address is broadcast. The MAC 
address is acquired using the response to this 
request. 
ARQ (Automatic Repeat Request) 
An error correcting method that error packet 
will be re-transmitted automatically when packet 
error is detected at the receiver (Decoder.) 
IP-9500/IP-900 series products have the 
real-time high error-control ability, equipped with 
the original “FEC + ARQ hybrid method.” 
BISS (Basic Interoperable Scrambling 
System) 
A scrambling system formulated by the EBU in 
May 2002. This system has 3 modes: MODE 0, 
MODE 1 and MODE E. In MODE 1, a 
12-character (48-bit) session word is used for 
encryption and decryption. In MODE E, a  
16-character (64-bit) encrypted session word 
and 14-character (56-bit) injected ID are used 
for encryption and decryption. In MODE 0, 
encryption is not used. 
BB (Black Burst) 
Sync signal of black level’s video signal which 
is used to be synchronize 
BNC (Bayonet Neill Concelman) 
One of the coaxial cable connecters which 
have the 75ohms impedance. It uses the lock 
called Bayonet Lock and is very easy and 
compact to use. It is used for the test gear and 
the digital audio because it supports up to 4GHz 
high frequency. 
Browser 
A generic name for programs that support a 
user who wants to fetch a desired option from a 
number of options. Using a browser, the user 
can trace links on the World Wide Web to 
access such multimedia information as text, 
audio, and video by the simple selection of items 
with a mouse or other pointing device. 
Carrier Frequency
 
Radio wave output frequency of a modulator 
card. Low-frequency transmission data is 
overlaid on a high-frequency signal during 
modulation, and this high-frequency signal is 
called a carrier wave. The frequency of a carrier 
wave is called the carrier frequency. 
CAT (Conditional Access Table) 
An information table to support the limited 
receiving. 
CC (Closed Captioning) 
Data for broadcast captioning. It is multiplexed 
at ancillary data area, virtual or horizontal 
blanking area of video signal, in HD/SD-SHI 
signal.
