The difference is it takes 2 fields to paint a single frame (so 60 fields for 30 frames). 1080p30 takes 1 field to paint a single frame, for 30 frames.
There is no difference at all between the two -- a simple accumulationbuffer in 1080i can just display every-other-frame and display the exact same picture as 1080p30.
