LSB
Least Significant Bit. The lowest weighted bit or signal line.
Luminance
The signal (Y) which represents brightness or the amount of light in the
picture. Luminance is the only signal required for black and white pictures.
For color systems, it is obtained as a weighted sum (Y = 0.3R + 0.59G +
0.11B) of the R, G, and B signals.
MSB
Most Significant Bit. The highest weighted bit or signal line.
NTSC
National Television System Committee. The organization which developed
the television standard currently in use in the United States, Canada, and
Japan. Now generally used to refer to that standard.
PAL
Phase Alternate Line. Refers to one of the television systems used in Europe
and many other parts of the world. The phase of one of the color difference
signals alternates from line to line to help cancel out phase errors.
P
B
A color difference signal used in component video systems. It is derived by
subtracting the B (blue) signal from Y.
P
R
A color difference signal used in component video systems. It is derived by
subtracting the R (red) signal from Y.
RF
Radio Frequency. In television applications, RF generally refers to the
television signal after the picture carrier modulation process.
RGB
Red, Green, and Blue. Also referred to as GBR in SMPTE specifications.
The three primary colors used in color television's additive color reproduc-
tion system. These are the three color signals generated by the camera and
used by the picture monitor to produce a picture.
R–Y
One of the color difference signals obtained by subtracting luminance (Y)
from the red camera signal.
Saturation
The property of color which relates to the amount of white light in the color.
Highly saturated colors are vivid, while less saturated colors have more white
mixed in and, therefore, appear pastel. For example, red is highly saturated,
while pink is the same hue, but less saturated.
