[Mp4-tech] [H.264] What is the difference of complementary field pairs and non-pair field?

[yaguang xie]

hi Song,
      As my comprehension, there are two kinds of complementary field pairs, complementary reference field pairs(both of the two fields are reference picture) and complementary non-ref field pairs(both of the fields are non-reference picture). 
   If the two fields of a frame is different for reference property,for example, one is reference picture and the other is non-reference picture,either of the field is non-paird field. the reference one is called non-paired reference field, and the non-reference one is called non-paired non-reference field.

          Dear Expert,
  Can you explain the difference of complementary field pairs and non-pair field? I cannot understand the definition of the standard, it makes me confused for long time.
  Thank you and Best Regards.
