DVD-Video Digital Versatile Disc is a storage medium that combines the convenience of the

compact disc with the latest digital video technology. DVD-Video uses modern

MPEG-2 data compression technology that enables an entire film to be stored

on a single five inch disc. DVDs come in different formats, such as single-sided

or double-sided. Each side can have a single layer or two layers of data.

DVD-5 A DVD that is single-sided, single-layered, holding up to 4.7 GBytes of data.

DVD-9 A DVD that is single-sided, dual-layered, holding up to 8.5 GBytes of data.

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.

HDCD High Definition Compatible Digital. It is a coding/decoding process with a clear-

ly improved sound quality for CD and CD-R software which has been recorded

accordingly. The integrated HDCD decoder in the device decodes these signals

and ensures the natural sound characteristics.

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.
