However, the artifacts created by compression of interlace direct is
probably more noticeable then artifacts created in the de-interlacing stage.

For the compression to be progressive, the video needs to be deinterlaced.

We think in terms of few TV networks vs. millions of TV sets.  But those
millions of sets make it possible to get fine deinterlacing silicon (think
the Realta chip).  No TV station will buy a $250,000 deinterlacer (and not
even THAT can do a perfect job).


There's no question progressive is the way to go.  But, as we speak, more
hours of interlaced HD are being generated.

TTFN,
Mark
