Multi-session
A method of data recording for CDs or DVDs.
Data is written to the disc in a number of
sessions.
Unfinalized CD
To be able to play an audio CD, it must be
"finalized" after burning. During this process,
information about the contents of the CD is
stored for reading out later by a drive. Without
this information, the contents of the CD remain
hidden or the CD cannot be detected.
PBAP (Phone Book Access Profile)
The PBAP makes the data from the phonebook
available to the integrated hands-free unit so
that the driver can retrieve and dial numbers
in the phonebook using the devices available
in the vehicle.
PTY (Program Type)
Classification of the FM radio stations by type,
for example pop music, news, classical, jazz,
etc.
Radio text
Radio text transmits additional information
such as the name and artist of the track
currently playing or contact details for the
station.
RBDS (Radio Broadcast Data System)
RBDS is a technique for the transmission of
inaudible additional information in the FM
waveband.
In addition to the widely used functions for
program identification, traffic program, and
alternative frequencies, RBDS also offers
further options for additional information/
services (however these are rarely used by
radio stations).
Regional code
A Video-DVD with a unique regional code can
normally only be read by a DVD player that is
also set to this regional code.
The market does, however, also offer "regional
code free" players that play DVD-Videos from
all regions.
SMS (Short Message Service)
SMS is a telecommunications system for the
transmission of text messages that was
initially developed for GSM mobile telephony
and is now also available in the conventional
telephone network.
Surround

placement of sound sources in a room using
several loudspeakers (surround sound).
Touchscreen
A touchscreen is a computer screen with areas
that can be touched to control the program flow.
UMTS (universal mobile telecommunications
system)
UMTS is a standardized system for universal
mobile telecommunications.
This standard will replace the old mobile
communication via GSM, as it is applied in the
D and E networks, with an enhanced range of
services. UMTS will support powerful
multimedia services in the multimedia field in
particular thanks to its high transmission rates.
In addition to voice and audio services, these
include fast data, graphics, and text
transmission as well as the transmission
of pictures and video.
Vanity numbers
Vanity numbers are telephone numbers that
can be represented as a word thanks to letter
dialing. With a vanity number, each letter is
assigned to a digit on the phone keypad. This
allows a telephone number to be represented
as a catchy word instead of a numerical
sequence.
