Quick Notation Question - Data Rates/Frame Rates/Interlacing

Finally upgraded to a decent prosumer camera and I'm trying to decipher what the manual is telling me about the many different formats it shoots and and the associated options.  I keep seeing things like "There are two basic shooting modes: 720p and 1080i/p.", which I'm finding confusing.  In my understanding, the "p" in 720p means progressive video and the "i" in 1080i means interlaced.  So what do I make of 1080i/p?

 

On top of this, my camera shoots in "native" mode, which drops duplicate frames used in "over 60" formats.  This will give me variations in the notation like:

 

  • 720/24pN
  • 720p Native 60 fps
  • 1080i/24p
  • 1080/24PN

 

 

Can someone give me a quick primer about frame rate vs data rate and explain how to read these notations?  I'd appreciate it quite a bit.

 

Thanks!
