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