Hi Guiseppe, many thanks for getting the ball rolling on this.

The BBC would be very interested in participating in a TF looking at these  
issues. As has already been mentioned on this list, we have been pursuing  
work in this kind of area, so a TF would be a very welcome forum to  
further work in these areas.



Some thoughts on the initial draft:

Great to see service discovery being mentioned early on. Enabling this  
 from the browser does seem key to so many things.

Broadcast style TV services/content should be included when considering  
the kinds of content to be accessed by a device. It is still a popular  
medium :-)

The 2-box / 3-box distinction and the assumption of a need for content  
type negotiation assume a particular structure/model for interaction and a  
particular level of abstraction. Does this implicitly pre-select  
particular solutions (eg. UPnP) for the inter-device application layer  
protocols?

I also feel it may be too limiting, at this stage, to confine the scope to  
just JavaScript APIs. This assumes the existence of suitable inter-device  
application layer protocols. The existence of JavaScript APIs is the (or  
at least a major) desirable end-goal, but we might identify other elements  
that are required.

Arguably content discovery and playback are the two most important  
elements, but devices such as connected TVs have many other functions -  
eg. apps, recording capabilities etc. Many of these functions may also be  
useful to access from other devices within the home. There is also the  
opportunity to comprehensively improve accessibility if most key functions  
of such a device can be exposed through suitable APIs.



many thanks



Matt
