First I'd like to point you to the book

Video Demystified: A Handbook for the Digital Engineer, 5th Edition

It's an excellent resource on anything video and readily available from Amazon

Check out VESA formats to see what H & V sync look like.  DE is normally generated from H & V so the reverse should be possible from DE and FRAME.

The ADV7511 is basically a parallel to serial converter.  I am not sure if you even need H & V sync.  It would be interesting to try.  Just replace VSync input with Frame and tie off HSync and run it in DVI mode.

I'd get a ADV7612-7511P evaluation board to test it out.
