Tracking Signals output by a computer are output at a certain predetermined
frequency.
If the frequency of your projector cannot match that frequency, a
clear image cannot be obtained. Matching of signal frequencies is
referred to as matching tracking. When tracking is not matched, a
projected image displays broad vertical bands.
USB An abbreviation for universal serial bus, an interface for connecting
a personal computer with a relatively low-speed peripheral device.
VGA Refers to a 640-pixel (Pix) horizontal x 480-pixel (Pix) vertical
display signal for an IBM PC/AT-compatible (DOS/V) computer.
XGA Refers to a 1024-pixel (Pix) horizontal x 768-pixel (Pix) vertical
display signal for an IBM PC/AT-compatible (DOS/V) computer.
YCbCr The carrier signal which is contained in the color bar signal used in
modern TV transmissions (NTSC format). The name comes from
the Y (luminance) signal and the CbCr (chroma [color]) signals.
YPbPr The carrier signal which is contained in the color bar signal used in
high-definition TV (HDTV) transmissions. The name comes from
the Y (luminance) signal and the PbPr (color difference) signals.
YUV This signal consists of three components, the luminance (Y), red
minus luminance (U) and blue minus luminance (V).
The human eye is more sensitive for changes in brightness than
changes in color. By using this feature, the data volume assigned to
the brightness is larger. To prevent a deterioration of the image
quality, a high data compression rate is used.
This signal format is used for digital video data.
