GLOSSARY

DVD-10

A DVD that is double-sided and single-layered, which holds up to 9.4 GBytes of

 

data. This disc must be manually flipped to use both sides.

DVD-18

A DVD that is double-sided, dual-layered, holding up to 17 GBytes of data.

DVD+RW

DVD+ReWritable uses phase change media, the same technology on which

 

rewritable CDs are based. A high-performance laser is used to change the

 

reflective properties of the recording layer; this process can be repeated more

 

than thousand times.

DVD+R

DVD+R (write-once DVD). Unlike a DVD+RW disc, the disc can only be written

 

to once. If it is not finalised after a recording, further recordings can be added to

 

it in a DVD recorder. Old recordings can be deleted but can no longer be over-

 

written. Before this disc can be played in a DVD player, it must be finalised in a

 

DVD recorder. Once this process is completed, no further recordings can be

 

added.

DVD+R DL

Dual-layer DVD+R disc that expands the storage capacity of the DVD to 8.5 GB.

 

There can be made recordings with a length of up to four hours in DVD quality

 

when using this kind of disc.

Interlace

It is a process in which the picture is split into two fields by sending all the odd

 

numbered lines to field one and all the even numbered lines to field two. This

 

allows a whole picture to be produced in two very fast scans.

JPEG

Joint Photografic Expert Group. File format for pictures with high compression

 

degree.

kHz

Kilohertz. kHz is the indication for the height of the scanning rate with which an

 

analogue signal (PCM) is interrogated for the following analogue/digital transfor-

 

mation.

Macrovision

Analogue copy protection which scrambles the video signal when used with

 

VHS recorders. Also has an effect on some projectors and monitors.

MP3

A compressed audio format. MP3 files recorded on CD-R or CD-RW media are

 

suitable for playback on your DVD player.

MPEG

Moving Picture Experts Group. Compression method that is used for digital

 

video records, e.g. for Video CDs or CDs.

MPEG-4

Latest compression method standardized by MPEG group with greater com-

 

pression capabilities.

NTSC

National Television System Committee, television norm among others in the

 

USA and Japan (from 525 lines only 480 lines will be transferred with a picture

 

changing frequency of 60 half pictures per second).

PAL

Phase Alternation Line, television norm in Germany and other European coun-

 

tries (from 625 lines only 576 lines will be transferred with a picture changing

 

frequency of 50 half pictures per second).

Pan & Scan

When used with a normal TV (4:3 aspect ratio), this setting results in the typical

 

“Pan & Scan” display, where a movie is clipped on the sides to fit on the TV

 

screen.

PCM

Pulse Code Modulation. Linear data stream, which arises from the scanning of

 

an analogue signal in the same intervals.
