GLOSSARY

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.
Interlaced	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 trans-
	formation.
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.
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.
Progressive Scan	Is a method of making a computer picture by drawing all the scan lines sequen-
	tially from top to bottom resulting in a slightly brighter, more stable and flicker
	free picture.
Region code	DVD movies are produced with region encoding to restrict distribution of titles to
	certain areas at certain times. To play back a DVD title with a specific region
	code, you will need a DVD player with the same region code.
RGB	Electrical transmission possibility for video pictures, i.e. it is a picture signal,
	which is splintered according to the primary colours of the TV (red, green and
	blue).
