RCA-type Jacks: Standard connection used for analog and digital purposes.
Composite video jacks are labeled yellow, and standard audio cables for left (white)
and right (red) channels. RCA type jacks are also used for YPbPr component analog,
Dolby Digital/DTS digital coaxial audio, Super-Audio/ DVD-Audio analog multichannel,
etc.
Resolution: Capability of a video device to reproduce (or an image to resolve)
detail. The term is generally used to express horizontal resolution, as the number of
lines/pixels that can be displayed in the horizontal direction (see horizontal
resolution).
Response Time: A specification typically associated with LCD panels used to
indicate how fast pixels react to changes of light and avoid a blurring effect that
typically shows as trails and pixel movement that is not in the original content while
displaying fast moving objects on the image.
The measurement is expressed in milliseconds and, depending on the manufacturer,
indicates the time it takes a white pixel to show black and back to white again,
others express that as gray-to-gray, or just indicate the time it takes to become
black from white but not to white again (half of the white-black-white task) which
certainly appears as a faster spec to unsuspected consumers (such as SXRD’s Sony
RPTVs did when introduced with 2.5 ms spec).
Many LCD panels that were 20ms in 2004-5 have gradually been improved to 16, 12,
8, 6, and even 4 ms. The smaller the number the faster the pixel reaction time is
and the better the LCD should be in avoiding the blurring effect on fast moving
images.
Retrace: Action of moving the electron beam from the end of one scanning line to
the beginning of the next one. Usually associated with CRT type of display devices.
RGB: Red, Green, and Blue color signals (chrominance), primary components for
color television; the primary colors of light. RGB video can be transmitted as: RGsB
(the Green contains the sync signal), RGBHV (sync separate from colors, horizontal
and vertical separate), RsGsBs (sync on each of the colors), and RGBS (sync
separate from colors). See component video.
RMS (Root Mean Square): Measurement of continuous power output produced by
an amp. The higher the RMS number, the cleaner, and louder (without distorting)
the sound will be; one of the primary specs to base an amplifier purchase. Peak
power ratings show the maximum wattage delivered by an amp during a brief burst
during a musical peak.
Saturation: Term that expresses the purity and intensity of a color signal, and the
extent by which it is free from white (less white results in more color saturation, less
saturation results when adding more white to the color).
Scanning: Action of moving an electron beam horizontally and vertically across the
raster in CRT video.
Scan Velocity Modulation (SVM): SVM adjusts the rate of horizontal movement
of the beam as it "draws" the scan lines. Dark areas look larger over lighted
background; lighted areas appear smaller over dark background. It is generally
