J
JPEG/JPG: Joint Photographic Experts Group is a committee that has
developed a standard method of compression for digital images. This
JPEG method (JPG for short) named after the committee is a widely used
graphic format for photos.
L
LAN: Abbreviation for Local Area Network. Mainly used as a designation
for networks with wiring (Ethernet).
LCD: Liquid Crystal Display.
LCN: Logical Channel Numbers. In stations with LCN, the channel loca-
tion number belonging to the station is also transmitted by the provider.
The stations are sorted according to these channel location numbers.
L-Link: Intelligent system connection between Loewe devices for the
automatic exchange of information. Makes the operation of TV and
Loewe system components even more convenient.
LNB/LNC: The crucial electronic component of a satellite antenna is
referred to as an LNB (Low Noise Block Converter). It is mounted in the
focal point of a parabolic antenna. The designation LNC (Low Noise
Converter) indicates that conversion to lower intermediate frequency
takes place. The supplemental block in the LNB refers to the fact that a
whole frequency range (a block) is converted in each case.
M
MAC address: Hardware address of a network adapter, e.g. the network
card in the PC. It is permanently assigned by the manufacturer and is
used to uniquely identify devices in networks.
Mbit/sec: Information about the transfer rate in networks in megabits,
i.e. millions of characters per second. With WLAN, the maximum speed
is 11 (IEEE 802.11b) or respectively 54 (IEEE 802.11g) Mbit/sec, in wired
nets 10 Mbit/sec or 100 Mbit/sec (Fast Ethernet).
Media server: Stands for the device which multimedia contents are stored
on, but is also the name for the service provided by the device that makes
this data available to the network.
MHEG-5: Digital teletext standard of the Multimedia and Hypermedia Ex-
pert Group. At the moment only available in United Kingdom and Ireland.
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 audio.
MPEG: Digital compression process for video.
MP3: Data format for compressed audio files.
Multimedia contents: Videos, music files and photos are grouped together
under this term.
N
NAS: Abbreviation for Network Attached Storage. 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 specification is
necessary in specific cable networks of some countries. Then only DVB
signals of this station network are searched for.
Network Mediaplayer: The technology in your Loewe TV set which pre-
sents multimedia contents on the screen for you.
NICAM: Audio standard. Is used in Denmark, England, France, Sweden,
and Spain.
NTSC: American picture standard.
P
Page Catching: For Teletext, refers to going to and calling a page number.
PAL: European picture standard.
PCM: Pulse Code Modulation for digital audio.
Picture in Picture: See PIP.
PIP: Picture in Picture; a function which displays two pictures on the
screen.
Pixel: Refers to the smallest unit of a digital grid graphic and its repre-
sentation 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 faults. 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: A port is part of a network address (or also IP address). It allows
assignment of data packages to various services which are running on
one device under the same network address.
Progressive JPEG: Progressive JPEGs are built up gradually. The picture
quality improves continuously during loading.
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: Stands in connection with WLAN encoding for Pre-Shared Key.
Clients, who want to connect up to a wireless network secured with
PSK have to know this key.
