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).
Vibrant­Colour
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.
