彩条信号是一种实用的电视标准测试信号,它可在彩色电视机屏幕上显示出按亮度递减顺序排列的8条等宽竖条,其颜色从左到右依次为白、黄、青、绿、紫、红、蓝、黑,包括了光的三基色(红、绿、蓝)及其补色(青、紫、黄)和非彩色(白、黑)等各种典型颜色。彩条信号波形简单,每行都一样。我国规定,在电视信号发射、传递和磁带录象中采用“100/0/75/0”彩色信号,在彩色电视编码器和解码器的调整和测试中通常采用“100/0/100/0”彩条信号,此信号由于波形简单,在演示各种波形及修理调试过程中经常要使用。
Color bar signal is a practical television standard test signal, which can be displayed on the color TV screen according to the brightness decreasing order of 8 vertical stripes, the color from left to right are white, yellow, green, Green, purple, red, blue, black, including the light of the three primary colors (red, green and blue) and its complementary colors (cyan, purple, yellow) and non-color (white, black) and other typical colors. Color bar signal waveform is simple, each line is the same. Our country stipulates that “100/0/75/0” color signals are used in transmitting, transmitting and videotape recording of television signals. In the adjustment and testing of color television encoders and decoders, “100/0/100/0 ”Color bar signal, the signal due to the waveform is simple, in the demonstration of various waveforms and repair often use the process of debugging.
