Component Video
Typically used on DVD players and HDTV systems, component video is a
standard Red/Green/Blue (RGB) color signal for televisions. The signal is
split and compressed into separate luminance and color values—luminance
(“Y”), red minus luminance (R-Y), and blue minus luminance (B-Y). The
value for green is not transmitted. The display device automatically “fills
in” the color values that are not red or blue. DVDs are encoded using
component video, so display devices will provide enhanced playback when
this type of connection is used. A common variant of this format used in
North America is YPbPr.
Composite Video
Composite video is a type of analog video signal that combines both
brightness and color information into a single signal. It typically uses a
single RCA connection for the video channel, and separate RCA
connections for the left and right audio channels. The quality of the video
signal is reduced by the process of mixing the brightness and multiple color
channels together into a single channel. For this reason it is inferior in
signal quality than either S-Video or component video. Composite video is
the broadcast format for analog television signals worldwide, and
connections are typically available on VCRs, DVD players and video
games.
CRT
Acronym for “cathode ray tube”, which is the main component of computer
monitors and TVs. Color CRTs use three separate electron beams fired
through a shadow mask and onto the back of the glass screen. The electron
beams activate separate red, green, and blue values in various strengths in
order to produce a colored image.
Dithering
A computer graphics technique that takes advantage of the human eye’s
tendency to mix two colors that are adjacent to each other to produce
smooth boundary transitions. Dithering adds intermediate color values
between two or more boundaries, producing smoother, more natural look
to 2D images or 3D objects.
