A composite video signal is a signal in which all the components needed to generate a video signal are embedded in a single signal. The three main components that together form a composite signal are as follows:
The monochrome composite signal is built of two components: luma (or luminance) and synchronization. This signal, which is usually called the Y signal, is shown in the following figure.
The chroma signal by itself, which is usually called the C signal, is shown in the following figure.
The composite color video signal, often called the Color Video, Blank, and Sync (CVBS) signal, is the sum of Y and C.
CVBS = Y + C
The two components Y and C can also be distributed separately as two independent signals. These two signals together are called either Y/C or S-video.
Y/C = S-video
A component video signal is a signal in which all the color components needed to generate a video signal are transmitted separately. Most HDTV formats are component (Y-Pb-Pr).
