GLOSSARY
MEMC
Improves the display of moving images through
the additional computation of intermediate pic-
tures and is only available for devices from 32".
It is displayed with a PPR of 400 (Picture Perfec-
tion Rate). If the adjustment value is too high,
this may result in ghosting with poor transmission
due to the incorrect computation of the interme-
diate pictures.
MP3
MP3 is the abbreviation for MPEG-1 Level 3
and is based on the MPEG-1 standard, which
was developed by the MPEG (Motion Picture
Expert Group).
NAS­(network­access­storage)
The abbreviation NAS is used for devices that
provide data from a hard drive to a network.
Network name (SSID) The network name
(SSID – service set identifier) is the term used
for the identification of a wireless network that is
based on IEEE 802.11. Every wireless LAN has
a configurable SSID, which uniquely identifies
the wireless network. The character sequence of
the network name can be up to 32 characters
in length. It is configured in the base station
(access point) of a wireless LAN and set on all
clients which access it.
Network­mask
The network mask or net mask, sometimes also
referred to as a subnet mask, is a bit mask that
separates an IP address into a network part and
a device/host part. It is used in IP networks to
make routing decisions.

Nois­Reduction
Reduces the visible snow by displaying the
picture a little less sharply and creating a slight
blurring. Should therefore be used minimally
with good picture material.
Perfect­Clear
Improves the general image by means of a
gentle blue hue (giving the appearance of
greater sharpness) and improves the black level
by setting this entirely to black from specific
shade of back. This reduces the visible grey
values in the dark areas of the picture.
Private­IP­address
Private IP addresses belong to particular IP ad-
dress ranges that are not routed in the Internet.
They can be used by anybody for private Net-
works, such as LANs. Many computer networks
require complete connectivity at IP level, but
only limited access to the Internet. If such a com-
puter network has a private IP address range,
it forms an intranet which cannot be accessed
from the Internet as the Internet routers ignore
private address ranges. A gateway or router
that is placed in this private network and which
has a public address in the Internet as well as a
private IP address makes the connection to the
Internet. This can be performed by a proxy or
using NAT/PAT/Masquerading. As the address
range used can only be viewed within the pri-
vate network, the same range can also be used
in other private networks. The unique nature of
an IP address required by the Internet protocol
is ensured by this restricted visibility.
Proxy­server
A proxy or proxy server is a service program for
computer networks that administers data trans-
fer. It makes data transfer faster, and can also
increase security by implementing access control
mechanisms. The transfer is conducted between
computers or programs in computer networks.
On the server side, the proxy acts as a client; on
the client side, it acts as a server.
