ADV7280A vertical video adjustment

Hello,

We are using ADV7280A with progressive mode for the display application. Our active PAL resolution is 704 x 583. Video first active line is start from 18th line on odd frame and 331th line on even frame. But from decoder ADV7280A these lines are not coming out. It gives only from 23rd line on odd frame and 336th line on even frame. Because of this we are losing top potion of active video on the display.

Can you help us to do the manual adjustment for vertical frame adjustment on ADV7280A. what are the register need to program for this requirement.

Regards,

Bala
