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
automatically switch between them.
Audio Video (A/V) A term often used when discussing a channel on a TV receiver or on video equipment, which has
been especially designed to accept VCR audio-video signals. This channel automatically activates
special circuitry within the TV set to prevent picture distortion and skewing. It is also used for
audio-video processors, which handle both types of signals.
CVBS Composite Video Baseband Signal. In broadcast television this refers to the video signal, including
the colour information and syncs.
Component Video
Input (Y Pb Pr)
Component Video Input is a type of connection that uses a cinch-type connector to allow set
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.
HDTV The generally agreed upon denition of HDTV is approximately twice the vertical and
horizontal picture resolution of today’s 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).
Progressive Scan In Progressive Scanning all the horizontal scan lines are scanned on to the screen at one time. The
HDTV Standards accept both Interlaced Scan and Progressive Scan broadcast and display meth-
ods.
Resolution Resolution: A measurement of the nest (smallest) detail that is visible in a video image. TV Reso-
lutions 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: 576i - The picture is 720x576 pixels, 576p - The picture is 720x576 pixels.
HDTV: 720p - The picture is 1280x720 pixels, 1080i - The picture is 1920x1080 pixels,
