What are the differences between RGB and YUV image signals?
A RGB signaling refers to the method of dividing an image signal to the fundamental three colors (Red, Green and Blue) when processing the signal. It has the advantage of good color division and conveyance, but the disadvantage of requiring at least 3 color division data. 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). Color division and conveyance qualities are inferior compared to the RGB method, but the YUV method can express more diverse colors using less image data. The choice of both methods are available on DVR. RGB image will have clearer color but more ‘blocks’ on the image, while with YUV image dividing between colors can be more difficult but you will get a more smoother looking surface from them.
