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.
