RE: About some issues (RE: Alcatel Space interest about IP/DVB)

["Harald Skinnemoen" <harald.skinnemoen@nera.no>]

Hi,

I've been following this discussion from interest from the sideline, as
I am involved with ETSI work that is related to IP over Satellite, and
in particular Multicasting and Addressing & Routing as part of a
so-called specialist task force at ETSI. 

The Broadband Satellite Multimedia group (WG BSM) is involved with a
number of issues related to what is discussed here - and yes - Alcatel
is very much involved I this work too. 

I've got two things... 

First I would like to invite comments and input on how satellite
multicast - in the future - could be made as efficient as possible with
respect to issues like those Horst Clausen points out - spectrum
efficiency. Naturally, satellite multicast would need to offer IP
multicast compatibility, but one could also imagine a special satellite
solution. I think satellite multicasting also could favorably be
combined with caching. This could increase the number of receivers that
could share the same channel, and thus reduce the cost. I would
appreciate help to find good references and for those of you who might
want to influence future ETSI standards, I would also be happy to invite
suggestions for specific issues that should be contained in a future
standard. 

Second, and as a natural follow-up of the first, I would also invite
this group to not only work with DVB and ATSC, but also ETSI... ;-)
