The one on the picture is called composite connector, compared to component, which used the same connector type but different colors codes. You had to be very careful where you plug them in your VHS player.

In composite the red and white plugs were the left and right sound, and the yellow the image. Van Gogh had one ear, so only one audio connector, Beethoven was deaf, so only yellow video, Ray Charles were blind.
