Hi All,

This is not quite IPDVB-related, but this seems like the most likely 
place to reach DVB experts in the IETF...

Do you have any comments on the attached request that IANA allocate 
two if-type values for (apparently) DVB-related protocols? 
Particularly, do you have any thoughts on whether these are 
proprietary or industry standard protocols?

AFAIK, there is no problem with allocating these values, we are just 
trying to determine how they should be named.

Please include Bert Wijnen in any responses, as he may not be 
subscribed to the IPDVB list.

Thanks!

Margaret
