"if there is only one video packet per VOP then it is probably useless, as VOP header could have been used for sync."
That is true, unless you have corrupted fields in the VOP header, in such cases the HE of the video packet will be useful indeed.

  Gaurav is correct.. i will elaborate it further
  for error resilience is implemented in three ways:
  1. Video Packet (Slice Resynchronization)
  2. Data partitioning
  3. RVLC.
  first level is Video Packet.
  so if there are more than one video packet in VOP, it provides a mechanism to synchronize the data at the decoder end.
  if there is only one video packet per VOP then it is probably useless, as VOP header could have been used for sync.
  Best Regards,
  Gautam

    Yes, video packet is lower layer as compared to VOP and decoding is VOP -> Video Packet -> MB.
    What's the confusion? I didn't really understand your question.

      hi
      now i have a question: in my view, video packet should be in lower layer than VOP, when decoding macroblock, we must go through VOP->Video Packet ->Macroblock, is it right? then what's the actual relation between Video Packet and VOP?
      thanks for help!
