GLOSSARY TO TELEVISION TERMS
56
Audio/Video Inputs * Located on the rear of the TV these
connectors (RCA phono type plug) are used for the input of audio
and video signals. Designed for use with VCRs (or other
accessories) in order to receive higher picture resolution and offer
sound connection options.
Coaxial Cable * A single solid antenna 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.
Display * An on screen message or graphics that help the user
operate and adjust TV feature controls. See On Screen Displays
(OSD).
Identify* Method by which a remote control searches and finds an
operating code for another product (such as a VCR or Cable
Converter). Once the code has been "identified" then the TV
remote can operate and send commands to the other product.
LED * Light Emitting Diode or indicator.
Menu * An on-screen listing of feature controls shown on the TV
screen that are made available for user adjustments.
Multichannel Television Sound (MTS) * The broadcast standard
that allows for stereo sound to be transmitted with the TV picture.
On Screen Displays (OSD) * Refers to the wording or messages
generated by the TV to help the user with specific feature controls
(color adjustment, programming, etc.).
Picture -In-Picture (PIP) * Term used when two pictures are
shown on the TV screen at the same time. The smaller PIP picture
is supplied by a VCR (or other tuner/video playback source). The
PIP picture can also be moved and swapped with the TV's main
screen picture.
Pre-Amplifier * The control center of a hi-fi system. Not only
amplifies source inputs, but also allows for source selection,
volume, tone, balance and all other controls that affect the sound.
Programming * The procedure of adding or deleting channel
numbers into the TV’s memory circuits. In this way the TV
“remembers’’ only the locally available or desired channel
numbers and skips over any unwanted channel numbers.
PTV * Projection Television (Rear and/or Front projection design
systems are available.)
Remote Sensor Window * A window or opening found on the TV
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) * Another or 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.)
Status * Allows the user to quickly confirm what channel number
is currently being viewed. Status can also be used to clear the TV
of on-screen displays or information (rather than waiting for the
displays to “time out” or automatically disappear from the screen).
Subwoofer * A speaker designed for audio playback of only the
lowest-frequency notes (under 100 Hz.)
S-Video Input * Allows direct connection of high-resolution video
sources, such as a Super VHS videocassette recorder, Laser Disc
player, etc. Provides improved picture resolution, sharpness, and
clarity.
Twin Lead Wire * The more commonly used name for the two
strand 300 Ohm antenna wire used with many indoor and outdoor
antenna systems. In many cases this type of antenna wire requires
an additional adapter (or balun) in order to connect to the 75 Ohm
Input terminals designed into the more recent Televisions and
VCRs.
Variable Audio Output * An adjustable audio output which
allows for volume variations at the source.
