Just some info when IP over DVB is considered.

The DVB Project is currently in the process of defining commercial
requirements for a new DVB-S specification, and form of "DVB-S2", that will
take into account adaptive coding, modulation and power control in the
forward/downlink. This work is currently being done in the DVB-BSS group.

At our last ETSI meeting in the Broadband Satellite Multimedia Work Group
(WG BSM) we discussed and agreed to aim for cooperation between the work
ETSI is doing and DVB. Most likely DVB will continue focus on Broadcast
aspects, while ETSI will focus on the Telecommunication aspects.

Just like IPv4 most probably will be out there for quite some time, the
general consensus seems to be that IPv6 also needs to be considered.

I think it may make a lot of sense to also consider a new, not yet defined
standard for a forward/downlink standard.

With the specification not yet written one also has the possibility to
influence it by providing input of particular considerations that would help
optimize IP over satelite. Such issues could include security, QoS, PEP and
more.

I have included some background info that was sent out by Peter Barnett
(DVB-BSS chair) recently at the end.

The DVB-S satellite standard was ratified by ETSI in 1994.  Since then,
technology has moved on, and it is now possible to obtain greater digital
capacity in a transponder by using advanced techniques.  Broadcasters in the
USA have indicated an urgent need for higher capacity, driven by high
definition television and "must carry" rules, but the position of other
broadcasters is not known.  The DVB Commercial Module wishes to define the
commercial requirements for future satellite standards on a broad basis,
taking into account issues including the need for backwards compatibility,
multicast, unicast, differences in the use of Ka- and Ku-band systems,
advancing satellite technology, transition to new standards, and above all,
the types of services that will be required to be carried.

The BSS group is examining both DTH and non-DTH applications, covering the
range of broadcaster requirements, and taking account of non-broadcaster
applications that might take advantage of our standards, much the same way
as some Internet backbone services use DVB-S at present.
