    CVBS input need SDP,but "It is not possible to output the FIELD synchronization signal in SDP mode on the output pins DE/FIELD and VS/FIELD".

   How can get FIELD output for CVBS input?

  Does "ADI recommends using the following synchronization methods to interface the back end device to the ADV7441A:• Use the synchronization signals HS, VS and DE" mean according to the relative position between VS and DE?'

  0x33(Vsync Field control 3) register :VS changes state at star tof line in odd field,VS goes low in middle of line in even field?
