A video signal that separates the video signal into three separate signals (and three separate wires) to avoid any quality loss from mixing signals. Component video describes a video signal that is split into two or more components. It is generally used to express analog video information that is stored or transmitted as three separate components. "Component video" cables do not transmit the audio signal, that's why separate cables are used for audio.
The components can be RGB (red, green, and blue); luma (Y) and two chroma signals, such as Y, Y-R, Y-B; or other formats including YUV, YCbCr, or Y Pr Pb. Requires a separate audio signal and connector.
Analog Component Video
Reproducing a video signal on the screen is complex due to the many different signal sources. DVD, VHS players, computers, etc. they process and transmit video signals differently. One way to preserve the clarity of the video signal is to separate the signal into its components and transmit them in such a way that they do not interfere with each other. The signal that is separated into its components in this way is called component video.
RGB Analog Component Video
Since it does not have compression feature in various RGB and analog component video standards and it contains a lot of unnecessary data, it requires very large bandwidth in signal transport. In today's computers, this signal is given via the VGA port. Especially in Europe, many televisions use RGB via SCART connection. All arcade games, early vector and black-and-white games follow RGB except for its use.
