sRGB
An international standard for color intervals that was formulated so that colors which are reproduced by video equipment can be handled easily by computer operating systems (OS) and the Internet.
SVGA
A type of image signal with a resolution of 800 (horizontal) x 600 (vertical) dots which is used by IBM PC/
SXGA
A type of image signal with a resolution of 1280 (horizontal) x 1024 (vertical) dots which is used by IBM PC/
Sync. (Synchronization)
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals (the relative position of the crests and troughs in the signal) is called "synchronization". If the signals are not synchronized, problems such as flickering, blurriness and horizontal interference can occur.
Tracking
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the resulting images will not be of a good quality. The process of matching the frequency of these signals (the number of crests in the signal) is called "tracking". If tracking is not carried out correctly, wide vertical stripes will appear in the projected images.
VGA
A type of image signal with a resolution of 640 (horizontal) x 480 (vertical) dots which is used by IBM PC/
XGA
A type of image signal with a resolution of 1,024 (horizontal) x 768 (vertical) dots which is used by IBM PC/
YCbCr
The carrier signal which is contained in the color bar signal used in modern TV transmissions. The name comes from the Y (luminance) signal and the CbCr (chroma [color]) signals.
Glossary
YPbPr
The carrier signal which is contained in the color bar signal used in 
) transmissions. The name comes from the Y (luminance) signal and the PbPr (color difference) signals.
