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

In the UK, (and I believe in Europe) Line 22 is becoming the de-facto
standard, for EIA 746 type VBI insertions. Some broadcasters (such as the
BBC) would find difficulty using any other line. The relationship with UK
style Teletext (and URL's that might be carried in teletext) is unclear.
The transmission and interpretation of events in the digital domain is still
in need of better definition. The UK mandates DVB rather than ATSC, and
there are some hints how to do this for the MHEG regime, but further
definition is needed.

The immediate applications we see are for program adjunct material, and for
EPG use.
