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 videocas-
	settes 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,
	or television).

	that you’ll scroll through when using your remote.

	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.

	eliminate redundancy and dramatically increase picture and sound quality.
DOLBY DIGITAL	Dolby Digital Cinema Sound is made possible by a new digital coding tech-
	nique called Dolby AC-3. Dolby AC-3 produces high-quality, 5.1 channel
