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 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.
