RE: ip-dvb - PROPOSED CHARTER

["Bernhard Collini-Nocker" <bnocker@cosy.sbg.ac.at>]

I fully agree that QoS can be a quagmire. However, I doubt that there can
be one single framework that solves it all. Independent from any compression
and coding there are specific capabilities, requirements, and limitations
of any physical and link layer, which have to addressed and met.

We should also work in this proposed group on the issues Internet people
are interested in, which may be different to those of the DVB people.

I remember from the early standardisation meetings of the DVB groups that
there were many people from the broadcast and telephone world, but few did
care about Internet. Finally, it would be good to approach the whole story
from another point of view.
