Re: Resolving btv URLs

Also, the URIs would not be entirely opaque. For example, a URI referring to
a data item in a data carousel being broadcast as part of a data event could
consist of a leading portion identifying the data event, followed by a path
which defines how to navigate the Data Service Table and the Carousel
directory to get to the data item. Moreover, for program events which are
developed by a broadcaster for its own channel, such as local evening news,
the event URI may often consist of the channel URI followed by terms. In
this case the database may only need to contain the channel URI, and the
receiver can tune to the channel to pick up the "DNS" records to resolve a
reference to the specific event.
