I was in a discussion that 30p is not on NTSC broadcast spec as well as BluRay spec. PsF was used indeed in delivering progressive content through interlace device/broadcasting. Basically, each full progressive frame is split into two fields. Since at each moment, both fields are showing the exact same content, the progressive content is preserved. Here is a graphic presentation of what PsF works.
 

 
While at the discussion, I was asked how 60i and 60p affiliates from each other. Here's another graphical presentation.
