ADV7611: no hsync during vsync

Hi, in my ADV7611 design both hsync and sync are active low signals. For the 
duration of sync active (low), hsync also becomes low. But in my design I do require, 
that hsync pulses do continue in the vsync active period. Is there a setting in 
a register, where I can enable hsync pulses during vsync?

 

I have attached a screenshot with the hsync (blue - 37 kHz)) and vsync (yellow - 50 Hz) timing. It shows one field of a 1080i50 signal.

 

Thanks and best regards, Jurgen
