RE: FINAL CALL for Feedback on Charter
I
reiterate that the IP over DVB work is important.
A
layered system design with proper abstractions can serve many if that is the
objective.
Of
course there need to be transport specific bindings; but perhaps those do not
need to be in the common IEFT document (or they might be an informative annex),
as the authority for such transport specific binding standards would be DVB
and/or ETSI.

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.

The charter's
focus on IP over MPEG-2 being DVB centric is very troublesome.
Certainly
the developed method should enable IP over DVB-flavored
Transports.
However, as an international standard, it should enable IP over
all
flavors of transport, and not discriminate against other flavors.
ATSC,
ISDB and other systems (China's) should be enabled as well.
A generic
solution abstracted from the details of transport would
seem to have a much
larger marketplace.
I note that delivery of
IP over MPEG-2 has been solved for the ATSC
transport, and while the
standard is tied to ATSC announceme! nt, that tie
could be abstracted, as
it is not the heart of the technology. The IP
therein is a technically
separable layer. The essence of the standard is how
to deal with the
one-way issues that contrast IP over broadcast vs. two way
over the
internet.
See http://www.atsc.org/standards/a_92.pdf
The
current scope seems to be one of requiring re-inventing the wheel,
and
being narrow while doing so... perhaps a broader view would better
serve the
world.

Gorry et al.
Can you
email a text version directly to this mail group for those of us
off-line
most! of the time (at the moment :).
Cheers, Rod.
