Aspect Ratio e ratio between an image's length and its height.
Scr
eens with a horizontal:vertical ratio of 16:9, such as HDTV
screens, are known as wide screens.
SDTV and general computer displays have an aspect ratio of 4:3.
Contrast e relative brightness of the light and dark areas of an image
can b
e increased or decreased to make text and graphics stand
out more clearly, or to make them appear soer. Adjusting this
particular property of an image is called contrast adjustment.
DHCP An abbreviation of Dynamic Host Congurat
ion Protocol, this
protocol automatically assigns an IP address to equipment
connected to a network.

1,080 (vert
ical) dots.

Medicin
e.

HDCP HDCP is an abbreviation for High-bandwidth Digital Content
Pro
tection.

every other line.
IP Address A number to identify a computer connected to a network.
Progressive Projects information to create one screen at a time, displaying
the im

Even though the number of scan lines is the same, the amount
of icker in images decreases because the volume of information
has doubled compared with an interlace system.
