	   Can you explain this difference further?  Perhaps an example of

   OK, my musing on the differences between EPG and IPG.

   The content is pushed by an EPG, the user interaction is essentially
   passive, the schedule is simply displayed by channel or carousel; any
   'interaction' is limited to selection.  Teletext TV guides are an example of
   an EPG. 


   The content is drawn/pulled by a user interacting with an IPG.  The IPG
   would select/filter the content from a database based on the user selection
   criteria before returning the results.  IPG Software is acting as an agent
   for the consumer, either permanently or on demand.  The agent could also
   prompt the consumer at the start of specifically selected programmes.

   Some Example IPG scenarios, might include:

   *	Show me a list of news channels.
   *	Show me a list of films/movies from a selected genre.
   *	Select a review of a specific film/movie.
   *	Show me a list programmes suitable for family viewing.
   *	Tell me when programme X starts.

Personally, I would classify this as an EPG that had a decent feature
set (which most current implementations don't have) and the line between
EPG and IPG would be blurry at best.  However, you have made
your distinction clear and that's all that I asked for.
