(2)极大提高了图像的清晰度,但S-Video仍要将两路色差信号(Cr、Cb)混合为一路色度信号C进行传输,然后再在显示设备内解码为Cb和Cr进行处理。这样多少仍会带来一定信号损失而产生失真,而且由于Cr、Cb的混合导致色度信号的带宽也有一定的限制,所以S-Video虽然已经比较优秀,但离完美还相去甚远。4.分量输入接口分量信号有YPbPr、YCbCr两种标识,YPbPr表示逐行扫描亮度/色差信号;YCbCr表示隔行扫描亮度/色差信号。在YPbPr、YCbCr信号中,Y表示亮度信号,PbPr、CbCr分别表示蓝色差信号B-Y(U信号)和红色差信号R-Y(V信号)。
(2) greatly improves the sharpness of the image, but S-Video still needs to mix the two color difference signals (Cr, Cb) into one chrominance signal C for transmission and then decode it into Cb and Cr in the display device deal with. This will still bring some loss of signal distortion, and due to the mixing of Cr, Cb chrominance signal bandwidth also has some restrictions, so S-Video has been relatively good, but far from perfect. 4. Component input interface signal YPbPr, YCbCr two kinds of logo, YPbPr said progressive scan luma / color difference signal; YCbCr interlaced luma / color difference signal. In the YPbPr and YCbCr signals, Y represents a luminance signal, and PbPr and CbCr represent a blue color difference signal B-Y (U signal) and a red color difference signal R-Y (V signal), respectively.
