Glossary

A list of definitions for some of the words found in this guide as they relate to these TVs.

75 OHM RF CABLE	The round cable that comes from an off-air antenna or cable service provider. Each end looks like a hex
	shaped nut with a wire sticking through the middle, and it screws onto the threaded jack on the back
	of your TV.
A/V CABLES	Audio/Video cables. Three cables - Right audio (red), Left audio (white), and Video (yellow). A/V
	cables are used for stereo playback of videocassettes and for higher quality picture and sound from
	other A/V devices.
A/V DEVICE	Any device that produces video or sound (VCR, DVD, cable box, satellite receiver, set-top box, or televi-
	sion).
ADD (SHOW)	This function lets you add new channels to the channel list in memory that you’ll scroll through when
	using your remote.
AMPLIFIER	An external device that amplifies sound from a television, CD player, VCR, DVD, or other A/V device.
ANALOG TV	Traditional method of representing a television signal as a replica (analog) of the original picture and
	sound.
ANTENNA	The physical receiver of television signals sent over the air. A large metal piece of equipment does not
	always have to be visible for your home to be using an antenna.
ASPECT RATIO	The ratio of the horizontal dimension to the vertical dimension of a picture. Standard television in the
	U.S. today is generally transmitted and displayed in a 4:3 aspect ratio. High-Definition television will
	normally be formatted in the wider 16:9 aspect ratio.
AUDIO CENTER MODE IN	Input jack provided for connecting external Dolby digital preamplifier output to the TV, to use as the
	center speaker channel and enhance your home theater setup.

COMPONENT INPUT (PR PB Y) Series of input jacks provided for extremely accurate picture reproduction yielding a higher quality pic- ture than standard video inputs.

DELETE (HIDE)	Removes channels that you don’t watch from the channel list in memory.
DIGITAL TV	A new method of representing a television signal as a series of binary numbers (1s and 0s). This
	method allows for the signal to be manipulated to eliminate redundancy and dramatically increase pic-
	ture and sound quality.
DOLBY DIGITAL	Dolby Digital Cinema Sound is made possible by a new digital coding technique called Dolby AC-3.
	Dolby AC-3 produces high-quality, 5.1 channel surround sound which is six discrete separate channels

	left, front right, surround left, surround right and subwoofer).
