[Kwintv] teletext/cc/etc

   After seeing the great teletext progress, I decided to have a look at close 
captioning support.  There are some tools available already which do this, 
but I'm not sure how well they really tie into Qt model.  I am considering 
what might be a slightly different approach:

   vbi interface
   ---------------
        This would be a plugin which communicates with the vbi device directly 
and sends events to a teletext manager.

   teletext manager
   ---------------------
         This would have two components.  The first component would be for 
closed captioning types of data.  It could be configured by the user to 
display in a separate widget (say a drop-down below the video widget), or to 
display with an overlay (which would be called through the OSD).

         The second component would be the enhanced teletext widget.  It could 
work similar to the one Rich is implementing now.


   Is this feasible for teletext?  It clearly requires splitting the code into 
components for I/O and display.

    I think it's a good idea to make these plugins because apparently there 
are other protocols that work over vbi too, such as webtv.  It might be 
better to do each separate system with a plugin instead of putting it all 
into kwintv and using configuration settings.
