From the chart above, the 15pin D-Sub Connector has three separate connectors for the red, green and blue colour signals, and two connectors for the horizontal and vertical sync signals. In a normal standard AV analogue signal – the three colours can be wired together outputting a composite video signal or the colours separated as above but the two Horizontal & Vertical Syncs wired together giving you an RGB signal via scart.
The separation of the signals is one reason why a computer monitor can have so many more pixels than a TV set.
