  Hi Steffen,
    In MPEG-4 Video Coding, Data Partitioning is not supported in B VOPs.
  Although not mentioned explicitly, Interlacing and Data Partitioning cannot exist together.
  There are Profiles which support all 3 of these tools, as for example, Advanced Simple Profile (Levels L4 and L5), but all of these features may not be present in a single compressed bitstream.
  Best Regards,
  Parag.
