[Mp4-tech] Regarding MBAFF flag

[aditi G]

Dear Experts,
I have some doubts regarding MBAFF implementation in H.263.
If MBAFF is enabled, I know that macro blocks will be arranged in field
format rather than frame format.
I need to know that, the input video file, like clair.cif, need to be in
field scanned format?
How the macro blocks are arranged, while I am calculating the nC value in
CAVLC?
I read the H.264 spec and trying to understand the JM reference related to
this topic. But I didn't get enough.
If any one has the theory /concept behind MBAFF, I request to forward that
to me.
Regards,
AD
