AES/EBU
AES (Audio Engineering Society) and EBU
(European Broadcasting Union) standardized for
professional digital audio I/O (IEC-60958 TYPE-1).
It was applied to ANSI (American National
Standard Institute) too.
Alert log
Alert log is obstacle history of unit or network.
BNC (Bayonet Neill Concelman)
One of the coaxial cable connectors which have
75 ohms or 50 ohms impedance. It uses the lock
called Bayonet Lock and is very easy and
compact to use. It is used for test gear and digital
audio because it supports high frequencies of up
to 4 GHz.
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)
DCE is a term from ITU-T. Similar to modems and
DSUs, it changes signals to waveforms that are
suitable for their transmission routes.
Downconverter
Converting from an HD-SDI signal to an SD-SDI
signal.
DTE (Data Terminating Equipment)
One kind of terminal unit (e.g., PC). DTE is a term
from ITU-T, and it is paired with DCE.
DVB-ASI (Digital Video Broadcasting
- Asynchronous Serial Interface)
Standard interface in DVB (Digital Video
Broadcasting: European Digital Broadcasting
standardization organization) and used in MPEG
CODEC most commonly. It is an asynchronous
serial interface and standardized in ETSI TR 101
891.

Glossary

Embedded audio
A method to embed AES/EBU digital audio signal
into the blanking area of an SDI (Serial Digital
Interface) signal.
FG (Frame Ground)
Ground for a cabinet.
HD-BNC (High Density BNC)
One of the coaxial cable connectors which have
75 ohms or 50 ohms impedance. About four times
smaller than regular BNC connector.
H.264
One of the video compression coding systems
standardized, in May 2003 in this case, by the ITU
(International Telecommunication Union). It is also
standardized as a part of MPEG-4 (MPEG-4 part
10 Advanced Video Coding) by the ISO
(International Organization for Standardization).
Therefore, it is commonly called H.264/MPEG-4
AVC or H.264/AVC, showing both parties.
This technology is used for various applications
from those with low bit rates and low resolutions
like mobile TV to those with high bit rates and high
resolutions like HDTV. It is improved so that the
data capacity is half that of MPEG-2, which is in
widespread use.
H.265
One of the video compression coding systems
standardized, in January 2013 in this case, by the
ITU (International Telecommunication Union).
From the study phase of the research and
development team JCT-VC (Joint Collaborative
Team on Video Coding), it has also been called
HEVC (High Efficiency Video Coding) by VCEG
(Video Coding Experts Group) of the ITU and
MPEG of the ISO (International Organization for
Standardization).
H.265 has a high compression rate due to
optimization of the block size and other reasons,
and achieved compression performance that is
almost twice that of H.264. It will be used for 4K
and other high-resolution video, and video
distribution for mobile terminals.
