This setup is why it is considered a lossless product since the RBG signals that get removed aren’t seen regularly viewing distances on a television anyway.Īll DVDs, Blu-rays, cable boxes, satellite sets, and RF tuners natively transmit YCbCr or store it as the digital video signal. The higher frequency signal gets removed from the Cb and Cr in the YCbCr, allowing for more significant signal compression. When you get to the Cb and Cr, you see the color differences for the channels. This setup works to approximate monochrome content. With YCbCr, the luma channel is typically denoted with a Y or Y’, with the latter option indicated that it is gamma-encoded. It represents brightness (Y), blue minus brightness (Cb), and red minus luma (Cr). YCbCr HDMI outputs render colors as brightness and two chroma signals. RGB HDMI outputs express red, green, and blue signals. Does it matter which choice you use for your display in the RGB vs. Most people can’t see the difference when you switch between these options. Some models give you the option to select from two YCbCr choices: 4:4:4 or 4:2:2. ![]()
