Subject: AW: Workshop feedback sought

Dear Philipp,

thank you very much for organizing the workshop and also for your
hospitality during these two days. I think, I got a good impression of
what is going on in the Internet developers community and how different
TV and Internet look at the convergence of these two medias. In my
opinion, the workshop was a good start to get deeper into discussions.

Answers to your questions in the text

Best regards
Alexander

> The following topics had high priority:

> 1. New URL-scheme for TV channels [high] 
>     (new URL for content in TV services) 
>      broadcast-specific data on the Web (SI/PSI-like metadata:
>       schedule, etc.) 
[AB]  What is ment with "broadcast-specific data on the Web"? Using
SI/PSI-data in HTML-pages (That shouldn't be too complicated)? Or
sending SI/PSI-tables to receivers on the Internet for tuning purposes
and program control information (Why should we do this)? Or something
else?
> 2. Broadcast HTML (tv-related profile of CSS, HTML, etc.) [high] 
> 3. Authoring guidelines [high] 
> 4. Default style sheet for TV [high] 
[AB]  Good points 2-4. I think our Intercast editorial crew could
contribute something on these topics.


> The following topics had medium to low priority:
> 
> 5. Metadata description/transport [10]
> 6. interaction mechanisms for streaming media, linking [10]  
> 7. controlling streaming media [6] 
> 8. filtering/transforming data for specific devices 
>     device profiles [6] 
>      (re-processing color palettes, guidelines for ~,...) 
> 9. accurate layout control[5] 
[AB]  Important point for a broadcaster. In my opinion should this be
high priority.
> 10. transition effects in CSS [5] 
> 11. temporal layout in CSS [3] 
> 12. API to VCR controls (and other devices) [3] 
[AB]  The API is one of the central points in Digital TV, very
complicated and not yet solved. I don't know how we could work on that.
> 13. "unidirectional HTTP" [2] 
> 14. caching streaming content [1]

[AB]  See above.
