You are reconstructing the temporal resolution nicely, but I think that
you are halving your possible vertical resolution from 576 back to 288.

With conventional interlacing, eye/brain persistance would reassemble the
lines of the two fields, allowing each line to be resolved.  But your blit
and the filter blurs each two lines together.
