Re: looking for tv-related URI use cases/application scenarios

I'd stay away from specifics of carriage of URLs in VBI lines or
MPEG tables, etc.  But what Tim seems to suggest is that URLs are used 
to trigger "loading" of a "page" of content to enhance the video 
program.

The other two possible uses of URLs are: 
- announcement of a future TV show.  Placing such announcements on
    Web sites and within EPG data carried in broadcast TV content.
- association/binding of "channels" (NTSC channels/frequencies, or MPEG
    program within a transport stream) with references to such channels.
- references to any broadcast "object" (data item, video program, etc.)
    from anywhere (web pages, broadcast streams, databases...).
    This use is truly the universal resource identification function of
    URIs, and in many ways a generalization of all uses of URIs that
    people have mentioned to me.
