Precautions, Notes, and Abbreviation List
Digital Noise Reduction: noise
reduction feature of the set
Dynamic RAM
Digital Rights Management
Digital Signal Processing
Dealer Service Tool: special remote
control designed for service
technicians
Digital Transmission Content
Protection; A protocol for protecting
digital audio/video content that is
traversing a high speed serial bus,
such as IEEE-1394
Digital Video Broadcast - Cable
Digital Video Broadcast - Terrestrial
Digital Versatile Disc
Digital Visual Interface (d= digital only)
Enhanced Display Data Channel
(VESA standard for communication
channel and display). Using E-DDC,
the video source can read the EDID
information form the display.
Extended Display Identification Data
(VESA standard)
Electrically Erasable and
Programmable Read Only Memory
Electro Magnetic Interference
Erasable Programmable Logic Device
Europe
EXTernal (source), entering the set by
SCART or by cinches (jacks)
Full Dual Screen (same as FDW)
Full Dual Window (same as FDS)
FLASH memory
Field Memory or Frequency

Green TeleteXT
H_sync to the module
High Definition
Hard Disk Drive
High-bandwidth Digital Content
Protection: A "key" encoded into the
HDMI/DVI signal that prevents video
data piracy. If a source is HDCP coded
and connected via HDMI/DVI without
the proper HDCP decoding, the
picture is put into a "snow vision" mode
or changed to a low resolution. For
normal content distribution the source
and the display device must be
enabled for HDCP "software key"
decoding.
High Definition Multimedia Interface
HeadPhone
Monochrome TV system. Sound
carrier distance is 6.0 MHz

The ITU Radio communication Sector
(ITU-R) is a standards body
subcommittee of the International
Telecommunication Union relating to
radio communication. ITU-656 (a.k.a.
SDI), is a digitized video format used
for broadcast grade video.
Uncompressed digital component or
digital composite signals can be used.
The SDI signal is self-synchronizing,
uses 8 bit or 10 bit data words, and has
a maximum data rate of 270 Mbit/s,
with a minimum bandwidth of 135
MHz.
ITV Institutional TeleVision; TV sets for
hotels, hospitals etc.
LS Last Status; The settings last chosen
by the customer and read and stored
in RAM or in the NVM. They are called
at start-up of the set to configure it
according to the customer's
preferences
