PAL
The Phase Alternation Line procedure is the TV standard applicable for Europe. PAL pos-
sesses 625 lines per screen and the film transmission speed is 25 pictures per second. The-
se are transmitted in the so-called line-jump procedure where a picture with all the odd lines
and then a picture with all the even lines are created. This corresponds to a half-picture fre-
quency of 50 Hz.
SecurDisc
SecurDisc refers to a security technology that protects data carriers from unauthorized ac-
cess and duplication. SecurDisc can only be burned and password protected with a Se-
curDisc drive. Access with other drives is only possible to a limited extent. The following disc
formats are supported, although without the copy protection feature: DVD+R(W), DVD+-R
DL, DVD-RAM and CD-R(W).
Subchannel data
Subchannel data on a disc contains additional information, such as CD Text or information
on positions.
Track-At-Once
Track-At-Once refers to a write method in which each track is written to the disc individually.
The writing process is interrupted briefly after each track, i.e. the laser starts again for each
track. With this write method, it is only possible to continue writing to a DVD sometimes and
at a later stage. There is a pause of at least 27ms between tracks, which can be disruptive
for Audio CDs.
VCD
The Video Compact Disc saves movies and audio/video data in MPEG-1 format. In doing so,
the video quality from a VCD is similar to a VHS video. VCDs can store up to 74 minutes of
video material including stereo sound on a 650 MB disc. Most optical PC drives and DVD
players can play VCDs.
WAV
The WAV audio format, also called WAVE or Waveform audio format, is an audio format
from Microsoft and uses no data compression. WAV is the counterpart to the AIF format from
Apple.
