aspect ratio
A signaling method that usescontinuous changes in the amplitude or frequency of an
electronic transmission to convey information.
Refersto the ratio between the width and height of the screen. ThisTV has a 16:9
(widescreen) aspect ratio, as opposed to a 4:3 aspect ratio.

component video
Component video is sent through three cables:two color shade(chrominance)signals and one
brightness (luminance) signal. Component video achievesgreater color accuracythan
composite video or S VIDEOby splitting chrominance into two separate portions.

Composite video is sent through a single cable. Composite video combinesthe color shade
(chrominance) and brightness (luminance) information into one video signal.
A new technology for transmitting and receiving broadcast television signals. DTVprovides
higher resolution and improved sound quality over analog television.
A unit of the FederalCommunications Commission, Washington, DC,that establishes
television standards in the United States, such as NTSCColor, the standard used in this TV.
Radio Frequency.That part of the frequency spectrum in which it is possible to radiate
(transmit) electromagnetic waves.
S VIDEOrequires a single cable, which carries the brightness (luminance) and color
(chrominance) signals of the picture separately. S VIDEOprovides better resolution than
composite video, which carries the signals together.
VHF (Very High Frequency)is the part of the radio spectrum from 30 to 300 megahertz. UHF
(Ultra High Frequency)is the part of the radio spectrum from 300 to 3,000 megahertz.
Provides480 lines of resolution. Displaysimages using interlaced scanning,which first
transmits all the odd lines on the TV screen and then the even lines.
Provides480 linesof resolution. Displays images using progressivescanning, which transmits
each line from top to bottom.
Provides 720 lines of resolution. Displaysimages using progressivescanning, which transmits
each line from top to bottom.
Provides 1080 lines of resolution. Displays images using interlaced scanning, which first
transmits all the odd lines on the TV screen and then the even lines. I080i is one of the
formats used by HDTV(High Definition TV).
