Totally agree, that is why I started this discussion. Is important to  
discuss on this list and have a common understanding before rushing into

Agree, see other reply I sent where I talk of a meta-profile.
My proposal for this group is to work on a document that provides a guide  
on how to integrate an html5 (end co.) based environment with the layer  
right below it, to be able to support common use cases typical of TV  

I suspect that many groups are looking or will be looking into this. And I  
thought that making the common part together in this group will bring  
several benefits:
- better interoperability
- save time by making the effort in one place and reusing it
- get involvement from the web community

The document (in my view) will still need to be "profiled" by business  
fora to adapt it to their business models, with the advantage of having  
already a pretty advanced starting point.

Yes, this is what I'm proposing, not a focus on a single set-up but on the  
overall architecture. Those points where a generic enough decision cannot  
be made will have to be documented and the "variables" be identified so  
that business groups can limit their work on defining the value of such  

As mentioned in some other places, I'm not sure the word profile is  
appropriate for what I'm proposing. Would be probably better to talk about  
"Guidelines" for integration of tv services in a browser based environment  
(or something like this)
