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

Hello Harald,

Thanks for your input - and YES we are certainly willing and interested in
also working with the respective ETSI group(s).
I think we should keep the two "layers" apart - the Multicast Applications
and the encapsulation and transmission aspects.
This group, at least as I see it - Gorry might se it differently - should
concentrate on the encapsulation, keeping in mind what sort of applicatiopns
might predominantly be using it.
For multicasting applications we have developed a software system which is
noch used for the distribution of Envisat data via satellite and is working
fine. If you want an update on our system (it has changed quite a bit since
we met last time); please let me know.

Regards,
--Horst
