Glossary
M
MAC address: Hardware address of a network adaptor, e.g., he net-
work card in the PC. It is issued permanently by the manufacturer and
is used to uniquely identify devices in networks.
Mbit/sec: Information about the transfer rate in networks in mega-
bits, i.e. millions of characters per second. With WLAN the maximum
speed is 11 (IEEE 802.11b), 54 (IEEE 802.11g), 300 (IEEE 802.11n) or
1300 (IEEE 802.11ac) Mbit/sec, in wired networks 10 Mbit/sec, 100
Mbit/sec (Fast Ethernet) or 1000-Mbit/s-Ethernet (Gigabit Ethernet).
Media Server: Stands for the device on which multimedia content
is stored, but is also the name for the service provided by the device
that makes this data available to the network.
Modulator: Transmitter in the video or DVD recorder so that the
devices can receive signals via the tuner of the TV device.
Mono: Single channel sound.
MP3: Data format for compressed audio files.
MPEG: Digital compression method for video.
Multimedia content: Videos, music files and photos are grouped
together under this term.
N
NAS: The term describes a hard disk which is independently linked
to the network (i.e. without a PC).
Network ID: NID refers to the so-called programme ID number, also
known as network ID – a number between 0 and 8191. This specifica-
tion is necessary in specific cable networks of some countries. Then
only DVB signals of this station network are searched for.
NICAM: Audio standard. Is used in Denmark, England, France, Swe-
den, and Spain.
NTSC: American colour standard, stands for National Television
Standards Committee.
O
OLED: Abbreviation for Organic Light Emitting Diode. OLED is a further
development of the light emitting diode (LED) for display technology. In
contrast to LEDs, the coloured self-luminous OLEDs consist of organic
semiconductors that emit light in an electric field.
P
Page Catching: For teletext, refers to marking and calling a page
number.
PAL: European colour standard, stands for phase alternation line.
PCM: Pulse Code Modulation for digital sound.
Picture in Picture: See PIP.
PIP: Picture in Picture; a function which displays two pictures on the
screen.
Pixel: Also called picture element or pel. Denotes both the smallest
unit of a digital graphic grid and its display on a screen with grid control.
Pixel error: A pixel error is a defective pixel, usually on an LCD. Pixel
errors may be caused by production errors. They are expressed for
example by a constantly lit pixel or a constantly black pixel. Single
defective pixels however are excluded from a guarantee.
PNG: Abbreviation for Portable Network Graphics, a freely available
grid graphics format for loss-free compression.
Port: It allows assignment of data packages to various services which
are running on one device under the same network address.
Powerline: Powerline designates a type of wired network connection
in which data is transferred via the domestic electricity network using
optionally available adaptors.
Progressive JPEG: Progressive JPEGs are built up gradually. The qual-
ity of the picture increases progressively during the loading process.
Proxy server: Proxy means authorized representative or deputy. Proxy
servers provide indirect access to the network for systems that do not
have direct access to the Internet.
ProScan/Progressive Scan: Progressive Scan (abbr. PS) or full
picture method is a technique in the picture build-up of monitors, TV
sets, beamers, and other display devices in which the output device is
not sent line interlaced half pictures – unlike in the interlace technique
– but real full pictures.
PSK: Clients that wish to connect to a wireless network secured with
PSK must know this key.
R
RGB: Colour signals Red, Green and Blue.
Router: Device for connecting several networks, e.g., home network
and Internet.
S
Satellite tuner: Receiver for satellite programmes.
SDTV: Standard Definition TeleVision.
SECAM: French colour standard, stands for Séquentiel à mémoire.
Set-top box: Set-top box (STB for short) refers to a device in enter-
tainment electronics which is connected to another device, usually a
TV set, and offers the user additional functional options.
Signal input group: Depending on the applied signal, the signal
sources are divided into different groups.
Signal strength: Strength of the received antenna signal.
Signal quality: Quality of the incoming antenna signal.
Smart Card: The Smart Card is an electronic chip card issued by the
respective programme provider or by the certification free Pay TV
operators. It contains the code which is decoded by the CA module.
Static contrast ratio: Describes the relationship between the lightest
and darkest image display.
Stereo: Dual channel sound.
Switch: Device for connecting several computers to a network.
Switching voltage: Video devices supply this voltage to switch the
TV set to playback.
Symbol rate: Specifies the transmission speed for data transmission.
T
Terrestrial: In data transmission a wireless transmission that does
not use satellites as intermediate station is referred to as terrestrial.
TFT: Thin Film Transistor. One widely distributed application is control
of liquid crystal flat screens, for which a signal transistor is used for
each pixel. This design of display is also referred to as active matrix,
however it is frequently also referred to as TFT display.
Tuner: English for receiver. A tuner is a receiving component in TV
sets or radios. Stations transmit TV or radio signals simultaneously
but at different frequencies. The tuner is connected downstream of
the antenna input and selected, that is, it filters out the desired signal.
U
Ultra HD: Ultra HD (abbr. for Ultra High Definition) is a digital high-
definition video format, which is about four times the resolution of
HDTV.
USB: Universal Serial Bus. Serial bus system for connecting external
devices (USB card reader, USB stick).
UPnP AV Is used to control network devices from all manufacturers.
Has become a widespread standard for home networking.
