ENGLISH

SCR (Single Channel Router)

Unrestricted single cable system.

If your antenna system is equipped with a single

cable multi-switch, the televisions which are con-

nected to this antenna system can receive televi-

sion channels independently from one another.

Security (WEP/WPA)

WEP (wired equivalent privacy) is the standard

encryption algorithm for WLAN. It controls both

access to the network as well as ensuring the

confidentiality and integrity of data. This proce-

dure is considered insecure nowadays. For this

reason, more recent WLAN installations should

use the more secure WPA encryption.

Symbolrate

This is the number of transmitted symbols in the

digital transmission technology per time unit

Timeshift

You can pause the programme you are watch-

ing. This is a useful function, for example if the

telephone rings while you are watching a film

and you do not want to miss anything.

The programme is saved in the time¬shift memo-

ry of the external data medium.

A maximum of 60 minutes of the current

programme can be recorded in the time shift

memory.

Transponder

A transponder receives data on a satellite and

then transmits it again. For example, an earth

station can transmit data signals for television

channels to a geostationary satellite, which

sends this back to earth. Any suitable satellite

antenna with visual contact to the satellite can

receive the signal.

UHD TV

Ultra High Definition Television (UHDTV or Ultra

HDTV) and Ultra High Definition Video (UHDV)

are a digital video format which includes two

picture resolutions (4K and 8K). Resolution:

3840 × 2160 (UHD-1) or 7680 × 4320 pixels

(UHD-2).

USB-Recording

Enables recording and playback of television

programmes with digital television channels

(DVB-S, DVB-T and DVB-C). This depends on the

broadcaster.

Recording and playback of programmes can

only be carried out using an external data me-

dium (hard drive or USB stick).

Vibrant Colour

Increases the colour contrast and the contrast

adjustment. This setting is mostly too strong for

use with normal pictures and should only be

used where necessary (low or off) otherwise

nuances in the image can be suppressed.

Wi-Fi

The Wi-Fi Alliance is an organisation that has

taken on the task of certifying products from

different manufacturers on the basis of the IEEE-

802.11 standard, thereby ensuring that different

wireless devices can operate in parallel.

On 31 October 2002, the consortium an-

nounced a new encryption technology – Wi-Fi

Protected Access (WPA) – a part of the (then)

forthcoming IEEE standard 802.11i which would

replace the WEP encryption procedure, which

was already regarded as insecure before the

new standard came into force. After 802.11i

came into force, the Wi-Fi group coined the term

WPA2.

IEEE 802.11e is an industrial standard issued

by the Institute of Electrical and Electronics En-

gineers (IEEE) and a supplement to the wireless

LAN standard IEEE 802.11 for supporting the

quality of service.

802.11e works according to a similar principle

as the QoS procedure DiffServ. Data packages

in the WLAN are marked by the sender and the

access point is stopped in order to handle pack-

ages with higher priority.

With the aid of 802.11e, real-time application

such as Voice over IP are better supported as

they require a certain bandwidth in the network

to ensure the connection is not interrupted if

other network traffic creates too great a burden

on the available data transfer rate.
