All-

I would like to offer the following white paper as a framework for 
discussion of TV URI's in general:

	http://www.tbt.com/tvuriframe-03.htm

I have not updated it since Feb, so the links to the I-D's are broken 
- - sorry, but one of them is below.

Also, I wish to point out that the IETF I-D by Dan and Mark 
referenced below is in fact intended to be the same as the ATVEF tv: 
scheme.  And, tv: is unrelated to the ATVEF lid: scheme (noted below 
as the uhttp scheme).

And, while the DAVIC scheme (dsmcc:) is tv-related and useful, it is 
(DVB) transport-dependent, and thus difficult to relate in context to 
transport-independent schemes, such as the rest of these.

Hopefully the paper above will make some of this clearer.

	Mike
