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.
