色差接口(也称分量视频接口)有多种标示方式,如YUV、YCbCr Y/B-Y/B-Y等。在一些专业级视频设备和高档影视家电上,常以YPbPr和YCbCr两种标识,其中YPbPr表示逐行扫描色差输出,YCbCr表示隔行扫描色差输出。色差接口在颜色处理过程中忽略了绿色差Cg而只保留YCrCb,这样就避免了两路色差混合解码、分离的环节,并保持了色度通道的最大带宽,只需经过反矩阵解码电路就可以还原R、G、B三基色信
Color difference interface (also known as component video interface) There are a variety of marking methods, such as YUV, YCbCr Y / B-Y / B-Y and so on. In some professional video equipment and high-end video appliances, often YPbPr and YCbCr two kinds of logo, which YPbPr said progressive scan color difference output, YCbCr interlaced color difference output. The color difference interface ignores the green color difference Cg and only retains the YCrCb during the color processing, thus avoiding the two channels of color-difference hybrid decoding and separation and maintaining the maximum bandwidth of the chrominance channel, only the inverse matrix decoding circuit can Restore R, G, B trichromatic letter
