What is Composite Video?

Composite video signal (Composite Video Signal) is a method that compares the luminance signal (Y), red color difference signal (U), and blue color difference signal (V) in a video signal (U and V are collectively referred to as chrominance signal C, as opposed to luminance signal ) And synchronous signal composite transmission and storage. Because the equipment is relatively easy to manufacture, low in cost, and simple to use, it is widely used in standard definition televisions, video and audio equipment such as VCDs, and home television game consoles. The most well-known composite video equipment is the yellow composite video RCA terminal, which is easy to connect and only requires a cable to achieve video signal transmission.
