Chroma (V) Gain Register, Lower Byte
Memory Mapped Location 0x038 – (SAT_V_LO)
This is the alternate definition for the SAT_V_LO register when using the Bt848A/849A.
Upon reset it is initialized to 0xB4 (this must be changed to 0x80 to get standard chroma (V) gain values when in
digital video mode).
The SAT_V register when used in digital video input mode requires different programming to get the same V gain
adjustments as in analog video decode operation.

SAT_V_LO
This register is used to add a gain adjustment to the V component
of the video signal. By adjusting the U and V color components of
the video stream by the same amount, the saturation is adjusted.
