ENGLISH
	Aspect Ratio	The ratio between the width and height of the TV picture on the screen. In a normal TV set the
		aspect ratio is 4 to 3 (4:3). The new aspect ratio in HDTV is 16:9 which resembles the aspect
		ratio in a movie
		theatre (Widescreen). New TV systems support both 4:3 and 16:9 aspect ratio and can automat-
		ically switch between them.
FRANÇAISE	Audio Video (A/V)	A term often used when discussing a channel on a TV receiver or on video equipment, which has
		audio-video processors, which handle both types of signals.

	ATSC	ATSC: Advanced Television Systems Committee. Formed to establish technical standards for
		advanced
ESPAÑOL		television systems, including digital high definition television (HDTV).
	CVBS	Composite Video Baseband Signal. In broadcast television this refers to the video signal, includ-
		ing the colour information and syncs.
	Component Video	Component Video Input is a type of connection that uses a cinch-type connector to allow set
	Input (Y Pb Pr)	top boxes or analog DVD players to connect a signal to the TV. By offering the cinch-type input
		(YPbPr) the primary colors, red, green and blue are connected from a set top box directly into
		the TV allowing for the signal to display on the screen.
	DTV	Digital television. Generic term that refers to all digital television formats, including high-
		definition
		television (HDTV) and standard-definition television (SDTV).
	DOLBY Digital	Dolby Digital - Six-channel digital audio standard that is part of the U.S. digital television stan-

	Digital Tuner	A digital tuner serves as the decoder required to receive and display digital broadcasts. It can be
		included inside TV sets or via a cable receiver box.
	HDTV	The generally agreed upon definition of HDTV is approximately twice the vertical and
		horizontal picture resolution of today’s NTSC TV, which essentially makes the picture twice
		as sharp. HDTV also has a screen ratio of 16:9 as compared with most of today’s TV screens,
		which have a screen ratio of 4:3. HDTV offers reduced motion artifacts (i.e. ghosting, dot crawl),
		and offers 5.1 independent channels of CD-quality stereo surround sound, (also referred to as
		AC-3).
	NTSC	National television system committee. The organization that developed the analog television
		standard currently in use in the U.S., Canada, and Japan. Now generally used to refer to that
		standard. The NTSC standard
		combines blue, red, and green signals modulated as an AM signal with an FM signal for audio.
	Progressive Scan	In Progressive Scanning all the horizontal scan lines are scanned on to the screen at one time.
		The Digital TV and HDTV Standards accept both Interlaced Scan and Progressive Scan broadcast
		and display methods.
	Resolution	Resolution: A measurement of the finest (smallest) detail that is visible in a video image. TV
		Resolutions may be expressed as number of pixels in an image; or more commonly,
		As Total Number of (horizontally scanned) Lines used to create the image.
		Standard Digital TV Resolutions:
		SDTV: 480i - The picture is 704x480 pixels, 480p - The picture is 704x480 pixels.
		HDTV: 720p - The picture is 1280x720 pixels, 1080i - The picture is 1920x1080 pixels,
		1080p - The picture is 1920x1080 pixels.
	SPDIF	SPDIF (Sony and Philips Digital Interconnect Format) is highly recommended for high quality
		digital sound output.
