Glossary
P (continuation)
Progressive JPEG: Progressive JPEGs are built up gradually. The
quality of the picture increases progressively during the loading
process.
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 difference between the brightest
and darkest picture 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: Another term for receiver.
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.
V
VGA: PC interface for connecting a monitor.
W
WEP: Abbreviation for Wired Equivalent Privacy. Former standard
process in the WiFi encryption, now outdated.
Wired network: see LAN.
Wireless network: see WLAN.
WLAN: Abbreviation for Wireless Local Area Network. Also abbrevi-
ated as wireless network.
WMA: Abbreviation for Windows Media Audio, Microsoft own audio
data format. As with MP3 files, the content is compressed here as well.
WMV: Abbreviation for Windows Media Video, proprietary Microsoft
video data format.
WPA: Abbreviation for Wi-Fi Protected Access. Replaced WEP as
standard encryption for wireless networks.
Y
Ycc/Ypp: Colour standards for Set-top boxes..
YCbCr: Digital colour model, informally also incorrect designation
for signals in standard resolution (SDTV). The YCbCr colour model,
in which, e.g., DVDs are coded, has been developed from the YUV
colour model used in analogue television technology. With YCbCr, the
data is transferred via digital interfaces such as DVI or HDMI without
being converted.
YPbPr: Analogue colour model, see also Component connection.
The analogue YPbPr signal is generated from the YCbCr signal by a
converter in the source player and then output at the 3 component
outputs of the source player.
YUV: The YUV colour model is used for analogue television in accord-
ance with the standards PAL and NTSC. YUV is often informally re-
ferred to when YPbPr (for analogue connections/cables) or YCbCr (in
digital applications) is actually meant. YUV only occurs in quadrature
modulation during PAL or NTSC transfer and is not otherwise used.
