A signaling method that uses continuous changes in the amplitude or frequency of an
electronic transmission to convey information.
Refers to the ratio between the width and height of the screen and picture image. This model
has a 16:9 (widescreen) aspect ratio.
4:3 aspect ratio
Component video is sent through three cables: two color shade (chrominance) signals and one
brightness (luminance) signal. Component video achieves greater color accuracy than composite
video or S VIDEO by splitting chrominance into two separate portions.
Composite video is sent through a single cable. Composite video combines the color shade
(chrominance) and brightness (luminance) information into one video signal.
A process that demagnetizes the metal components in the TV monitor, which eliminates image
distortion that can result from magnetic charges acquired by the TV's components. Your TV
degausses automatically when it is turned on.
A new technology for transmitting and receiving broadcast television signals. DTV provides clearer
resolution and improved sound quality over analog television.
Provides an uncompressed, all-digital audio/video interface between this TV and any HDMI-
equipped audio/video component, such as a set-top box, DVD player, and A/V receiver. HDMI
supports enhanced, or high-definition video, plus two-channel digital audio.
A unit of the Federal Communications Commission, Washington, DC, that establishes television
standards in the United States, such as NTSC Color, the standard used in this TV.
RF
Radio Frequency. That part of the frequency spectrum that is used to transmit TV and radio signals.
S VIDEO requires a single cable, which carries the brightness (luminance) and color (chrominance)
signals of the picture separately. S VIDEO provides better resolution than composite video, which
carries the signals together.
VHF (Very High Frequency) is the part of the frequency spectrum from 30 to 300 megahertz. UHF
(Ultra High Frequency) is the part of the frequency spectrum from 300 to 3,000 megahertz.
Provides 480 lines of resolution. Displays images using interlaced scanning, which first transmits
all the odd lines on the TV screen and then the even lines.
Provides 480 lines of resolution. Displays images using progressive scanning, which transmits each
line from top to bottom.
Provides 720 lines of resolution. Displays images using progressive scanning, 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. 1080i is one of the formats used by
HDTV (High Definition TV).
