Anamorphic. A type of lens that "squeezes" a 16:9 widescreen picture into a standard
4:3 image. For proper playback, the image needs to be "unsqueezed" by display on a
16:9 screen or by letterbox presentation (with black bars at the top and bottom) of a 4:3
screen.
Artifact. An unwanted distortion of the video signal, visible on the screen.
Aspect ratio. The proportion of TV screen width to height. Conventional television has
an aspect ratio of 4:3. Modern, widescreen television has an aspect ratio of 16:9.
ATSC. Stands for the Advanced Television Standards Committee. An advisory group
that produced the table of 18 recommended transmission formats for Digital Television
(DTV) broadcasting in the United States.
Cathode Ray Tube (CRT). The most common television display technology, the CRT
is a sealed glass envelope in which the inside front surface is coated by phosphors. The
phosphors glow when excited by an electron beam—the "cathode ray." CRTs are used
for both direct-view and projection television.
CD-R/RW audio playback. Plays audio discs from your CD-R/RW burner.
Center channel. A speaker channel in surround sound systems. The Center channel is
crucially important because it creates the illusion that the dialog is coming from the
actors on the screen.
Chrominance. The color component of a video signal, abbreviated C. Chrominance is
combined with the black-and-white signal (luminance) in composite video connections,
but kept apart in S-Video and component connections. For higher quality, the single
chrominance signal can also be divided into B-Y and R-Y components in Y/P
B
/P
R
component connections, or into the primary colors of Red, Green and Blue for R/G/B
component connections.
CineMotion reverse 3-2 pull-down. A Sony feature that preserves the integrity of
movie film frames for spectacular, consistent fine detail in 480-line progressive scanning
(480p). In televisions, it works with all film-originated content, including broadcast TV,
cable TV, satellite TV and DVD.
Coaxial digital output. A method of connecting high-quality digital audio from a source
component to an A/V receiver.
Component Video connections (Y/P
B
/P
R
). Component video is the best method for
connecting analog video signals. Y/P
B
/P
R
is ideal for DVD players and compatible
satellite receivers. Uses separate connections for luminance (Y), blue color difference
(P
B
) and red color difference (P
R
).
Component Video connections (R/G/B). Component video is the best method for
connecting analog video signals. R/G/B is ideal for HDTV receivers and computer
signals. Uses separate connections for Red (R), Green (G) and Blue (B).
Composite Video connections. Composite video is the standard method of connecting
video equipment, but it is far from the best method. Composite video puts color
information (chrominance) together with black-and-white information (luminance) on the
