Term Tracking USB VGA XGA YCbCr YPbPr YUV Description 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. An abbreviation for universal serial bus, an interface for connecting a personal computer with a relatively low-speed peripheral device. Refers to a 640-pixel (Pix) horizontal x 480-pixel (Pix) vertical display signal for an IBM PC/AT-compatible (DOS/V) computer. Refers to a 1024-pixel (Pix) horizontal x 768-pixel (Pix) vertical display signal for an IBM PC/AT-compatible (DOS/V) computer. 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. 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. 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. 72
