How is component cable better than all the other connections (except HDMI)?
Component video was the first connection capable of transmitting high-definition video signals. It is an analog connection, so it is often slightly inferior to DVI and HDMI, which are all-digital, because the analog signal requires a D/A conversion. However, if your source and television have high-quality D/A converters, component video signals may be virtually indistinguishable from their digital counterparts. Component video derives its name from the method of transmission it employs. “Component video” actually refers to many different connections (VGA, RGB, YPbPr, YCbCr, etc.), but nowadays typically refers to YPbPr. Component video is superior to composite and S-video because it splits the signal into “components” and transmits the data via three separate cables. YPbPr cables transfer luminance data via one cable, and color data via the other two. This removes bandwidth limitations imposed by composite and S-video by dedicating cables to one purpose. Composite video transmits every
