Glossary Of Television Terms - Philips 60PP9401 Directions For Use Manual

Aspect Ratio * The proportions of a rectangular display screen. NTSC
television has a 4:3 ratio; HDTV is 16:9.
Audio/Video Inputs * Located on the front and rear of the TV, these
jacks (phono-type) 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.
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 on-
screen text boxes to show dialogue and conversations while a TV pro-
gram is in progress.
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 * On-screen messages or graphics that help the user operate
and adjust TV feature controls.
HDTV * High Definition Television, which offers approximately twice
the vertical/horizontal resolution of NTSC video, and sound quality
approaching that of compact disc. (Usually taken to mean a picture of
1920 x 1080 pixels in a 16:9 aspect ratio.)
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.
NTSC * National Television Standards Committee format devised for
TV broadcasting signals in the 1940s (525 lines; 30Hz.)
On-screen Displays (OSD) * Refers to the wording or messages gener-
ated by the TV to help the user with specific feature controls (color
adjustment, programming, etc.).

Picture -in-Picture (PIP) * Picture-in-Picture (PIP) is the showing of
more than one picture on the TV screen at the same time. You see one
main screen picture and a single subpicture or multiple subpictures.
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 sys-
tems are available.
Remote Sensor Window * A window or opening found on the TV con-
trol 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 dis-
played 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).
S-Video Input * Allows direct connection of high-resolution video
sources, such as a Super VHS videocassette recorder, laserdisc 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 sys-
tems. 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.
