GLOSSARY OF TELEVISION TERMS
General Information: Index
Alternate Channel • The feature that allows you to toggle
between the last two channels viewed by pressing the A/CH
button on the remote control.
Audio/Video Inputs • Jacks (standard RCA), located on the rear
of the TV, used for the input of audio and video signals. These
jacks are designed for use with VCRs (or other accessories) to
receive higher picture resolution and offer sound-connection
options.
Auto Program • The feature that, when activated, scans for all
available channels from regular antenna or cable signals and
stores only active broadcast stations in the TV’s memory.
Channel Edit • The feature that allows you to add or delete
channels from the list of channels stored in the TV’s memory.
Channel Edit makes it easy to limit or expand the number of
channels that are available to you when you press the CH +/–
buttons on your remote control.
Closed Captioning • The broadcast standard feature that allows
you to read the voice content of television programs on the TV
screen. Designed to help the hearing impaired, Closed Captioning
uses onscreen text boxes to show dialogue and conversations
while a TV program is in progress.
Coaxial Cable • A single solid wire normally matched with a
metal plug (F-type) end connector that screws (or pushes)
directly onto a 75-ohm input found on the television or VCR.
Comb Filter • TV filter that removes distortion, resulting in a
sharper and purer color display. The comb filter addresses the
annoying cross-color distortion that may occur in TV broadcasts
when, for example, the presenter wears a striped or checked
jacket.
Component Video Inputs • Inputs that allow the separate
reception of blue, red, and luminance signals. These inputs
provide the highest possible color and picture resolution in the
playback of digital signal-source material, such as the kind
available from DVD players. Component video inputs allow for
improved bandwidth information not possible through composite
video or S-Video connections.
Composite Video Input • An input in which all the components
required for displaying the onscreen image are combined in one
signal.
Convergence • The technique used in color TV for bringing the
red, green, and blue color beams together so that they hit the same
part of the picture tube screen at the same time. This avoids color
fringes around images in the picture.
High-definition Television (HDTV) • High-resolution digital
television. HDTV is high-resolution digital television. It has
lifelike pictures, and with it films retain their original width,
enhancing the home theater experience.
Incredible Surround™ • False acoustic management of the
audio signal that produces a dramatic expansion of the wall of
sound that surrounds the listener and heightens overall viewing
pleasure.
Interlaced • A picture-scanning technique that improves the
appearance of onscreen motion. It also helps smooth jagged lines
that are sometimes seen on curved and angled surfaces in the
picture.
Menu • An onscreen list of feature controls available for you to
adjust or set.
NTSC • National Television Standards Committee format devised
in the 1940s for TV broadcast analog video signals (525 lines: 30
Hz).
Onscreen Displays (OSD) • The wording or messages generated
by the television (or VCR) to help you with specific feature
controls (color adjustment or programming, for example).
Progressive Scan • A picture-scanning technique that doubles the
number of picture lines, eliminating the flicker and providing
a jitter-free picture.
PTV • Projection Television. (Rear- and/or front-projection
design systems are available.)
Remote-control SensorWindow •The window or opening found
on the television control panel through which infrared remote-
control command signals are received.
RF • Radio Frequency or modulated signal design used as the
carrier for television broadcasts.
Second Audio Program (SAP) • An additional audio channel
provided for in the Multichannel Television Sound (MTS)
broadcast standard. A monaural soundtrack included within the
recorded or video signal (usually containing a second language
translation for the displayed programming).
S-Video Input • Signal input that allows direct connection of
high-resolution video sources, such as a satellite receiver, DVD
player, S (Super)-VHS videocassette recorder, or video games.
Provides improved picture resolution, sharpness, and clarity.
480p • Digital picture format with 704 x 480 pixels, sent at 60
complete frames per second. This is the output format of
progressive-scan DVD players.
1080i • Digital high-definition picture format with 1920 x 1080
pixels, sent at 60 interlaced frames per second (30 complete frames
per second).
Tint • TV function that allows you to change the general color
balance between cool and warm. Adjust tint according to your
personal preference.
