34 Glossary

DVI (Digital Visual Interface) : A digital interface

standard created by the Digital Display Working

Group (DDWG) to convert analog signals into

digital signals to accommodate both analog and

digital monitors.

RGB signals : These are the three video

signals, Red Green Blue, which make up the

picture. Using these signals improves picture

quality.

S-VHS signals : These are 2 separate

Y/C video signals from the S-VHS and Hi-8

recording standards. The luminance signals Y

(black and white) and chrominance signals C

(colour) are recorded separately on the tape.

This provides better picture quality than with

standard video (VHS and 8 mm) where the Y/C

signals are combined to provide only one video

signal.

16:9 : Refers to the ratio between the

length and height of the screen. Wide screen

televisions have a ratio of 16/9, conventional

screen TV sets have a ratio of 4/3.

MHEG (Multimedia and Hypermedia

information coding Expert Group) : provides

standards for the coded representation of

multimedia and hypermedia information objects

that are interchanged among applications

and services using a variety of media. The

objects deﬁ ne the structure of a multimedia

hypermedia presentation.

HDMI (High-Deﬁ nition Multimedia Interface)

: Provides an uncompressed, all digital audio/video

interface between the TV and any HDMI-equipped

audio/video component, such as set-top box, DVD

player and A/V receiver. HDMI supports enhanced

or high-deﬁ nition video plus two-channel digital

audio.

System : Television pictures are not broadcast in

the same way in all countries. There are different

standards: BG, DK, I, and LL’. The System setting

(page 28) is used to select these different standards.

This is not to be confused with PAL or SECAM

colour coding. PAL is used in most countries in

Europe, SECAM in France, Russia and most African

countries. The United States and Japan use a

different system called NTSC.

MPEG (Moving Picture Experts Group) is

the nickname given to a family of International

Standards used for coding audio-visual

information in a digital compressed format.
