YUV signaling refers to the method of expressing an image signal by the vertical and horizontal signal synchronization (Y), and its color signals (U, V).

RGB images will have clearer color but more 'blocks' on the images, while with YUV images dividing between colors can be more difficult but you will get a more smoother looking surface from them.
