RE: FINAL CALL for Feedback on Charter

[Marie-Jose Montpetit <marie@mjmontpetit.com>]

I don't want to start a thread here (maybe I will) but I think one of the goals of the group is 1. to highlight what has been done before inlcuding the ATSC work (thanmks for the spec!) and 2. see how to define better solutions to specific issues (AR being one).
 
I agree that an abstract solution also needs to be worked on and actually this is being investigated by the BSM working group at ETSI where we are developping a technology agnostic solution not only for broadcast networks but for a whole range of DVB and satellite systems. This said we see the IP over DVB work as important not just because of the wide use of MPEG2 technologies but also as a proof of concept for more abstract work.
