Glossary
SVGA A type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is used by IBM PC/AT-compatible computers.
S-Video A video signal which has the luminance component and color component separated in order to provide better image quality.
It refers to images which consist of two independent signals: Y (luminance signal), and C (color signal).
SXGA A type of video signal with a resolution of 1280 (horizontal) × 1024 (vertical) dots which is used by IBM PC/AT-compatible computers.
Sync (synchronization) The signals output from computers and RGB video equipment 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.
Tra cki n g The signals output from computers and RGB video equipment 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.
USB An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which only support
relatively low data transmission speeds.
VGA A type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is used by IBM PC/AT-compatible computers.
XGA A type of video signal with a resolution of 1024 (horizontal) × 768 (vertical) dots which is used by IBM PC/AT-compatible computers.
