|
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 (24bits) 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.(16bits)
The choice of both methods are available on DVR.
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. |
