6.5 SDP COLOR CONTROLS

The following registers provide user control over the picture appearance. They are independent of any other controls. For instance, the
brightness control is independent of the picture clamping, although both controls affect the DC level of the signal. The ADV7850 provides
10-bit control of contrast, brightness, saturation, and hue.
