NSV[3:0]
NSH [2:0]
The horizonal ALC coefficient (NSH) specifies the number of the horizonal samples (N) used to calculate the average blank level per
horizonal line. Offset error correction is applied immediately based on the vertical (NSV) coefficient.
The vertical coefficient (NSV) specifies the amount of offset error correction (derived from NSH) that is applied to each line update.
NSV [3:0]: ALC vertical filter coefficient
